991.2 GTS Turbo Failure Issue - Page 3 - 911/Carrera GT - PistonHeads UK

Hi, I have just been informed by my local Porsche specialist (Weissach in Cheshire) that the turbos in my 57k mile 991.2 GTS have failed as per my own suspision. The remedial work appears to have been done in 2020 by Porsche and has always been serviced at the OPC's before and during my ownership. I was wondering if anyone else has any experience with dealing with these sorts of issues with Porsche ('good will' as its put to me) when the car has no official Porsche warranty but it is clearly a well known problem with the cars? I spoke to Porsche at Chester but they would like to do another inspection. Having been an owner of multiple Porsches, Caymans etc its all rather disappointing on a car which I've had for less than a year! Any advice would be greatly appreciated

Maybe take the opportunity to go wild and upgrade to better quality. I think I might put these in when the time comes. https://www.design911shop.com/p/tte600-upgrade-tur...

I had trouble enough getting Porsche to acknowledge the problem, even with a warranty. Why the hell this isn’t a recall matter I don’t know.

Is it not more to do with their position or is it a known issue and no bearing on their position at all?

Its a very common issue. As others have said use as an opportunity upgrade to turbos that will not fail. Litchfield and 9e worth a call too.

Active engine mounts fail quite regularly and the RWS mechanism/motor are also known to have issue…when one of the engine mounts failed in my car it was replaced without issue (under warranty)…two months later second one went. OPC told me that happens 50% of the time when they replace a single engine mount…Porsche wont let them replace them both. I do wonder what the deal is with the extended warranty in an issue like this. The extended warranty is an insurance product so the insurance company would take the financial hit….I wonder if there is some kind of push back from the insurance company to Porsche is there are repeated claims on something like this. I am guessing there is some kind of % threshold where the amount of failures triggers a recall or it is a safety issue.

Fair comment, I just wonder what the reputational damage threshold is.

I experience the smoky turbo symptom last year ( see my previous post ) For some reason , cost I suppose , OPC’s unless a very obvious sign of turbo damage have been instructed to replace turbo oil lines and drain pots as a first attempt at fixing smoky problem. It didn’t work for me and I needed one new turbo. Problem is the work involved for pipes etc is almost as much as replacing turbo so car had to go back for more days….OPC certainly don’t do themselves any favours when trying to avoid warranty work…I’m lucky to have a good connection with the techs that work on my car , they tell me it’s the warranty dept that cause all cheap fixes and bother. good luck with repair…great cars when working!

One issue in common with 911s is that all the kit outside of the engine block is sat there with no protection from salt and road debris. When combined with the cheap fixings it does seem to be a recipe for problems if used through the winter. At least the engine seems to have proved to be strong. As has been said, recalls tend to be for safety issues. Having said that, if owners clubs can generate enough noise then maybe Porsche might react. The 991.1 GT3 would be an example. The 992 has the same engine. I wonder if they’ve changed anything with the oil feed. This would give a bit of a clue. I suspect they are likely to have had some similar failures. Loads of these cars have been produced though.

If you’ve got a warranty it is there problem. Unfortunately the lesson here is don’t run a modern Porsche without a warranty…I’ve got three that are all under the extended warranty…I think when you look at the cost of repairing these cars and the fact that some parts can have horrendous delays the hire car they provide if a car isn’t roadworthy makes it worthwhile.

I cannot believe that this has been allowed to continue especially with these cars all being affected and having been out since 2016. I am trying to get some traction going with Porsche UK to get this sorted out. Any information from any owners would really help with this situation

Brilliant cars when they are working! But I agree, mine apparently had the remedial work done of replacing pipes etc but it still happen and just the left side that has failed but going to do both as I will more than likely be paying for it personally. It's basically the seals that go because of the pressure I feel with them being so low down - hence a fundamental design flaw! Thinking twice about another Porsche, 718 Cayman I had before for 4 years was faultless, expected the same experience but clearly not! I think as another poster says a warranty on any of these cars is required but a necessary 'Tax' to own one with these issues.

Loads of these cars have been produced though. The engine is solid! As per my specialist tells me. Ninemeister as per my previous post says that the 992 is the same design and will happen when they start to age a little more. My 991.2 GTS is on 56k miles and has just happened on a 67 plate - so overall from what I read I've actually been quite lucky and it has taken quite a long time (although having only owned it since May 23). I read another forum saying the oil seal had been improved with the 992 but Ninemeister disagree otherwise I would sell up and move up to one of those or unfortunately move away completely. I've had an Alfa Romeo Giulietta QV as a daily for the last 6+ years and been faultless so thinking a Gulia QV might be the best option going forward for reliability!

I completely agree, but buying any fairly modern Porsche now a days from a non main dealer (even with a full OPC history) usually doesn't come with the Porsche warranty as an option, in my case I was offered WarrantyWise which I didn't take as it wasn't getting very good feedback online and I'm sure wouldn't have covered this massive repair at 11.5k. I was after the manual version of the GTS which was hard to track down (last March) so had to stay out of the main dealers - sometimes there's no option. Unfortunately if I had waited a year I would have found many better options - but how long do you wait.. I agree with Porsche OPC service cars they provide, I had a Macan last year whilst my Cayman was in but surely this should be expected as standard with these sorts of cars even for an MOT or anything at an OPC? I just think If Porsche waived the inspection fee, paying for the Porsche OPC warranty would be fine..

If anyone has had any issues with their own 991.2 911 whether they have owned it in the past or currently own one - if they could message me directly with their experiences it would be really helpful with my own situation but also future situations with current or potential new owners and getting some sort of group and traction together that can sort this out for all. I think this is as a big an issue as with the GT3 and should be sorted out or at least admitted to by Porsche, even more so when the remedial work they do isn't sufficient. I guess my wishes of a GT3 are over for now!

Mine went & replaced under warranty, no where near your mileage.

I’ll be honest it is above my pay grade as a driver to describe the symptoms of the engine mount failure…I didn’t notice anything. I think for most people you’d need to be doing track work to notice. Mine was actually due on track when the warning light came up the first time mine failed…managed to get it replaced in time. I wouldn’t have taken it on track with one failed as would have been nervous of how the car may have behaved on the limit. With regards to the RWS when I took my GT3 to Center Gravity they said there was a small amount of play in one of the rear wheels….we’re talking tiny amounts and I’ve never noticed anything. I’d trust them over an OPC with these things…they felt it was something to keep an eye on at that stage. They’ve had several clients had them replaced though.

I have a recently purchased 991.2 GTS with 10500 miles, one of the turbos was replaced under warranty at 7500 miles.

I was told by my specialist that the 992 has the same design and issues but slightly more covered up in terms of the rust issue but I still think the oil pipe issue might still be present which I think is the bigger issue. I am speaking to Litchfield on Tuesday so I will see what they say as I heard they might have a proper fix. I am just after some clarification that if I down the official Porsche route and having to spend around 11-12k to get this issue sorted that it won't keep happening, as it seems pretty random. Some members report this happening at 7,000 miles whereas mine hit 57 and I have no knowledge of it being done before. Do you mind sharing your experience with how Porsche dealt with issue with yours and their explanation either via Forum or direct message, if you are able to spare the time?

I bought my 991.2 C4 GTS back in November 2021 when the car was on 13,000 miles. My car is now on 24,000 miles and is at Porsche Solihull with suspected turbo failure. The car was originally diagnosed with a faulty oil separator and replaced with a new one accordingly. My car went into Porsche Solihull on Monday 26th February. They delivered it back to me on Wednesday 20th March. I drove to work the following day and the dash lit like a christmas tree followed by clouds of blue smoke!! I limped it back to the dealership and they have put me back in the dreadful and gutless Macan T that I used for 3 weeks previously. I have a feeling I’ll be in the Macan for quite a few weeks yet

Took a fair while to get the parts for mine last summer. Hope the wait won’t be too long given the weather is just starting to pick up.

I asked about this when looking through the service history pre purchase. The service manager said it was due to the car being under used. Am not aware if anything was modified along with the turbo replacement.

Doesn't seem to be many who do that, even though personally that was the whole point of the 911 going back in history. It's interesting that you got warning lights on the dashboard, as I had nothing at all showing up. It was just observation that lot of smoke was coming out of the back during startup. After a long run and another startup it's usually fine but I guess that's because the oil had been burnt off from inside the turbos? Not to sure. I think as I keep sayings its with the oil lines being insufficient then taking out the turbos. What have the dealership been like to deal with and have they given you any info on what actually causes the issue? I think they have to keep to the warranty guidelines hence possibly not replacing your turbos right away. I think however the main issue is whether it will keep happening again and again. Some people report on this forum and others it happening at very low mileages and then mine at 57k which I guess is very late on from a 2017 car. I had to limp mine as well home and then as a safety measure have it trailered to the dealership! OPC's seem to be giving out the Macan T's generally for the curtsy cars. When my Cayman 718 was in for its first service and various recalls used to get a Cayman but the last time I went it was a Macan T. Its a nice car to sit in inside but totally underpowered with I think from memory the same engine from a Golf GTi pulling an SUV.. Can't believe it has the Porsche badge on its bonnet in that spec to be honest! If you could get any information on whether its an actual fix for the problem from the OPC or just replacing parts when you collect, I think it would be helpful for all on this one! I will be doing the same with my specialist when they have the parts required. At least you have the warranty that's all I can say, but even then its unacceptable for a car being sold currently in approved used by Porsche to have these issues and not be depended on. I'm having to pay 11-12k out of Porsche warranty

There must be loads around that require the same parts so can understand that, completely. Hopefully I can enjoy it a little over the summer before selling it and not worry about any road salts corroding the car underneath

It seems a completely random issue. Mine as I said is on 57k which must be high for a GTS going by ones for sale. I was reading about it and possibly because the car is highly revved or enjoyed after 3rd gear and this is when the pressures become too much and the seals and oil lines can leak or cause issues - so possibly more to do with this than underuse and enjoying the car occasionally!

It seems inherently unfair when this is such an obvious issue. I sincerely hope you can get a contribution towards the costs from Porsche as a goodwill gesture. I did actually consider not extending my warranty last November when the original 24 month Porsche Approved warranty was due to expire. I’m so relieved I did!! The first time my car went into Porsche Solihull it was on a trailer as I had to be recovered from the Cotswolds. The car lost power, sounded like a bag of spanners and I had 4 warning lights on the dash (AWD function limited, PSM failure, Engine control fault & Oil level below minimum). The vehicle inspection report confirmed cylinder deactivation and spark plugs needed for cylinders 2 & 6. The report also stated “oil being collected in the RH bank turbo intake” and “removing the intercooler to drain off and wash out the oil that has been drawn into the system”. Porsche Solihull have been woeful. Zero communication unless instigated by me. Messages to call me back with updates ignored. Not the kind of service I expect from a brand like Porsche I get the impression their workshop is overwhelmed with work. My car is due a service in May and I was advised to get it booked in last month!! I’ll give an update on the issue when I know more.

It was the 991.1 GT3 rather than the .2. Rennlist will have lots of information on the web. From memory, it was American owners who got together. My car is still going well, but I’ve anticipated the problem and have the turbo upgrade plan in my head. Maybe you should contact PorscheclubGB in the first instance?

I had my oil lines and both turbos replaced under warranty last September at around 25k miles. The OPC were great and all dealt with in a couple of weeks. I had the standard smoking on startup and large plumes of smoke on full throttle upshifts. On test my turbos were only achieving about 0.5bar on full boost when I dropped it off with them. I was told the replacement oil lines now have a one way valve which the originals didn't which stops oil being pulled back into the turbos on big pressure changes. The turbos are also revised and are now the same as the 992 which have additional protection around the main actuator.

Is this a GTS specific problem?

DMZ said: Is this a GTS specific problem? Mine is a T

Basically Porsche know there is a problem to upgrade the parts and should offer the same sort of warranty terms as on the affected parts as per the 991.1 GT3

Looks like Porsche has become complacent with their reputation for build quality, if this was happening to this extent from a certain British supercar manufacturer, there would be a lot of abuse around reliability issues. The saving grace is that the extended Warranty is quite cheap to compensate

My 991.2 S had both turbos replaced at 11k and 20k. I wouldn’t own this gen without a warranty - it’s not expensive anyhow and for me is a no brainier on the modern cars. As above there are updated design to try and stop it - I’ve only heard of a couple of 992 go this far so it seems to be less prone but high corrosion will effect eventually I suppose

I had a chat with my local Indy today (Ninemeister) as I'm getting a few bits done (Geo, clean underneath and seal with lanoguard, extra oil/filter change). If you have any info on the new oil lines then they will fit these for me as well? I suppose I could phone my OPC and see if they could help. Interestingly, he said that the 993 and 996 turbos did have one way valves in their oil lines.

It is unfair and wrong to be honest when there are so many people who state the same issues. With a majority of the cars being under Porsche warranty, I don't know why if they know there is a problem to be more proactive with getting it sorted out before customers have to break down out and about enjoying their cars! I tried to get in contact with Porsche Chester on multiple occasions prior to taking it to Weissach UK, they for some reasons were not picking up the phone on that day at all so I gave up and went with the Porsche accredited route thinking that the likelihood of Porsche giving any good will out of warranty was slim even though the car had always been serviced with them, even down to the tyres during and prior to my ownership. Having had to get the car trailered to the garage, I wasn't going to get it taken to Chester afterwards to possibly have to pay to bring it back again if they weren't going to help out financially. Weissach UK has been fair with their labour costs thus far, it's the part cost that is high. The whole thing is going to cost a little under £13k (fingers crossed) as it hasn't been completed. I also needed new rear springs as they had corroded and therefore snapped as well I'm glad you extended the warranty! - I think this is an absolute must with these cars. Unfortunately you save at the beginning (like me) but pay for it later on. You've absolutely got peace of mind!! It sounds like your situation is slightly different that mine, I didn't have any warnings or anything on the dashboard at all, just smoke but the car did drive although not with much boost. Porsche Solihull sound very disappointing thus far and absolutely not what you expect from this brand! I have heard the same rumour up here about them being overwhelmed with warranty repairs, especially from the likes of the Taycan etc. Look forward to hearing the update when you've heard back!

Grantstown said: It was the 991.1 GT3 rather than the .2. Rennlist will have lots of information on the web. From memory, it was American owners who got together. My car is still going well, but I’ve anticipated the problem and have the turbo upgrade plan in my head. Maybe you should contact PorscheclubGB in the first instance? I've just been reading about, interesting how they managed to do it. But yes possibly have to join the PorscheClubGB to be able to find any more insights. Glad to hear yours is going well! They are amazing cars. If you don't mind me asking though why do you think the uprated turbos would affect it if it's the oil lines? Or is more changed

Iknownothin said: I had my oil lines and both turbos replaced under warranty last September at around 25k miles. The OPC were great and all dealt with in a couple of weeks. I had the standard smoking on startup and large plumes of smoke on full throttle upshifts. On test my turbos were only achieving about 0.5bar on full boost when I dropped it off with them. I was told the replacement oil lines now have a one way valve which the originals didn't which stops oil being pulled back into the turbos on big pressure changes. The turbos are also revised and are now the same as the 992 which have additional protection around the main actuator. That is interesting. I wonder if they have revised the oil lines again since my remedial work was done. I noticed on 911 parts online that there are many revisions of the turbos so sounds like if I was on original turbos and not oil lines it wasn't fully resolved originally. What mileage was yours on?

DMZ said: Is this a GTS specific problem? It's any with the 3.0 Turbo engine. I was told that the Carrera and S are worse as they are even nearer to the floor than the GTS but not too sure on whether that's correct or not

GT4P said: Basically Porsche know there is a problem to upgrade the parts and should offer the same sort of warranty terms as on the affected parts as per the 991.1 GT3 I would absolutely agree! It's just going about how to raise enough noise about it really. Porsche GB might be a good place to start, so was going to post there as well.

PinkHouse said: Looks like Porsche has become complacent with their reputation for build quality, if this was happening to this extent from a certain British supercar manufacturer, there would be a lot of abuse around reliability issues. The saving grace is that the extended Warranty is quite cheap to compensate Think they're just hiding behind their brand a little too much. But yes if it was McLaren or Aston then we would all know about it. Ironically I decided against a the 4.0 2018+ Vantage as I thought the Porsche would be better built with no issues. But warranty is a must now I'm learning

Do you think it all went down hill with the 996 when they were struggling financially?

bosshog said: My 991.2 S had both turbos replaced at 11k and 20k. I wouldn’t own this gen without a warranty - it’s not expensive anyhow and for me is a no brainier on the modern cars. As above there are updated design to try and stop it - I’ve only heard of a couple of 992 go this far so it seems to be less prone but high corrosion will effect eventually I suppose Wow! Twice - did they mention anything after the first time about any changes or not to stop it happening at all or is it just with 992 that's properly been improved? But yes corrosions seems common on all due to the placement. I am definitely learning always have a warranty. I purchased from an independent Porsche specialist this time around, never again if I even stick with the brand

Turbo failure in 2022 at under 6,000 miles on my previous car a 2018 991.2 Carrera T. Repaired under extended warranty. OPC stated yours not the first & wont be the last….

When I enquired at Litchfield motors, the quoted cost was 9293 to have my turbos swapped out and to be refitted with GTS turbos and then to be retuned again. They said that this could go up a little if it needed new oil lines, which I think are a must, or if the bolts holding the turbos to the manifolds had seized. The power gain would have modest over my current 506bhp, so I left it for now as it’s plenty really. They do the turbos on an exchange basis. Turbos they remove are stripped and rebuilt with parts that are of a much higher standard of production. I’m at 34K, so my clutch may go soon as mine is a manual. My next drivetrain upgrade would then be to get a lightweight flywheel when the clutch is replaced.

I purchased from an independent Porsche specialist this time around, never again if I even stick with the brand The first time was before I owned the car - around 2020 so perhaps before the upgrades. Second time was literally the day after I sold the car to a dealer. I had called the local OPC about it during my ownership as she like to drink oil - but they insisted it was normal. Weirdly I had the smoke on start up thing only once - about 9 months before I sold it . I don’t know for sure , but given the 992 engine is the same any replacement parts would be the upgraded lines

rjh_36093 said: Hi, Thanks for the message, Tim. It is unfair and wrong to be honest when there are so many people who state the same issues. With a majority of the cars being under Porsche warranty, I don't know why if they know there is a problem to be more proactive with getting it sorted out before customers have to break down out and about enjoying their cars!

I have heard the same rumour up here about them being overwhelmed with warranty repairs, especially from the likes of the Taycan etc. Look forward to hearing the update when you've heard back! Porsche Solihull just called. They have found oil in the right hand bank turbo. Porsche have approved the replacement of both turbos, oil lines etc. I asked how much the claim will be. They said with the replacement oil separator, oxygen sensor, new turbos and labour it’ll be £15k +. Turbos are due in next week so I should be able to have the car back the week following.

Just renewed the warranty on my 11k miles 2018 991.2 Carrera T. No turbo issues certainly during my ownership of the last couple of years but it seems it's a case of when not if ! I did have the other much maligned water pump failure about a year ago at around 8k miles, I read around a bit and again seems like our US chums beat the drum very hard and got Porsche to extend the warranty on that part to 10 years in the States. Mine was obviously covered under warranty so no idea if there would have been any goodwill towards the repair this side of the pond ?? Also had a claim on the TPMS, I originally thought the batteries must have gone in the sensors but it turned out to be some rotted wiring to the sender unit or whatever it is on the body of the car ? Anyways goes without saying the warranty is a must in my view.

I would agree that the warranty is a good idea, unless you're in the situation where you wish to make the car much better than it was at the time of delivery, in which case they'll no longer be happy to issue a warranty. I've found the parts for the new pressure lines. Nice and cheap, but OPC suggests engine out! I suspect this is because of steel meeting aluminium and causing them to seize. I'll see what Ninemeister's opinion is on Monday. Generally they have solutions that are impossible to OPCs, who always replace everything in the most expensive way possible. And why not I guess if you get paid to do it by the warranty underwriters.

I’ve come across this as a potential easy device to decrease the risk of the issue oil building up in the turbos. https://www.vektorperformance.com/shop/vektor-perf...

I'm wondering if I'm the only one surprised by how common the issue seems to be, pointing to a design flaw. I wouldn't expect relatively new, expensive cars to be having such serious issues - surely the answer should be "Porsche should fix the design flaw/recall" rather than "Don't run a 991.2+ turbo car without a warranty because turbos will almost certainly go pop"?

You are likely in the minority, see 996/7 issues and 991 GT3 engine issues...

Recall’s mean you have to admit something serious is wrong with a car and also have to be informed to shareholders if significant. Neither of which Porsche will be keen to do….never mind the logistics of all 991.2’s needing workshop time which as we know is a nightmare at most OPC’s.

T25doc said: So looks like my 2016 2S @ 56k mileage has just hit this problem. Litchfield noticed smoke when they did my service some 3/4weeks ago and swapped out the oil return pipes, unfortunately for me though it looks like it hasn’t solved the problem and I’m now faced with replacing both turbos… Nice £9k cost or worse still just shy of £11k if they need to drop the engine out to replace the oil and water feed pipes that go across the top of the motor… Disappointing really, car isn’t a daily driver, and I do about 5k a year in it…didn’t take out Porsche warranty as I purchased the car originally from an Indy some 2yrs ago… Wife isn’t happy with me now and thinks it’s a money pit ?? Edited by T25doc on Tuesday 1st October 16:30 9K cost and you can upgrade to 992.2 GTS power without spending 90K and have another 8 years of fun. A new kitchen is a money pit as well!

Just wanted to let folks know about what has happened with my 992 Carrera S. It's on a 69 plate, I took delivery of the car brand new in January 2020. Quite early in the car's life, I think between 1 and 2 years old, the dashboard flashed up an engine warning telling me I had reduced power and that I needed to drive to a workshop. I did so and the OPC replaced the left side turbo. Then recently the same warning light came on the dash. The OPC have now replaced the right side turbo. The tech report states: "Turbocharger replacement on assembly bank 2. Wastegate arm cannot be cleaned up and greased". The car was also due a Porsche recall, campaign number WRC0. I think that was to check the turbo intake pipes (that is my memory of what the OPC told me a few days ago, please don't quote me). So mine is a relatively new car but has needed both turbos replaced within 5 years of new. Fortunately I have kept up the Porsche warranty so this cost me nothing except inconvenience. As I said above, Porsche have a recall on the 992 evidently (related to the turbos) so 992 owners may want to contact their OPC about that. Perhaps 991.2 owners should do likewise.

Sorry to hear that you're in the same situation as me on this one. How did you get on with Litchfield? Did you need to drop out the engine? Mine had to be done because it had all seized. £11k isn't too bad if the engine has to come out, it ended up costing me a fair bit more than that. Not good by any means but sounds like Litchfield are offering a fair price for the job. I got a third party warranty on mine via my specialist for around 1k a year which I have been promised by the Porsche specialist will cover new turbos should it happen again. The trouble is the issue hasn't actually been resolved even with new oil return pipes. I think it's a fundemental design flaw - so upgraded turbos etc still will not resolve it. I spoke with Litchfield on mine and they said there isn't a solution even with their oil collection device it can still happen.

This doesn't surprise me as the 992 has the same engine as the 991.2 and by the sound of yours doesn't look like its been modified by Porsche much to fix the issue. Possibly because the 991.2's have only more recently been more well known about. I asked my specialist whether they had ever had a 991.2 and 992 side by side to see the differences in the engine but they hadn't. Thanks for the info with the campaign number. It might be worth the other poster in this forum who has recently had problems to ring his OPC and see if there has been any change regarding a recall. Out of interest how many miles are on yours at the moment with the second turbo replacement? johnny senna said: Just wanted to let folks know about what has happened with my 992 Carrera S.

My turbos went on my 991.2 CS in August last year all replaced under warranty by the OPC, took about a week.

rjh_36093 said: The second turbo on my car was replaced last week and the car is currently on 24,000 miles. It’s a 69 plate 992 C2S.

I saw Porsche specialist Weissachuk post on Instagram yesterday that they were fixing a 991.2 with a turbo failure. Along with fitting some updated genuine Porsche oil lines. Maybe Porsche have updated a part causing the problem?

Wonder why the Turbo/S models don’t seem to suffer from this?

This was my car! They did a great job with it and is running well. Mine had already had the updated lines done prior and it still happened. Unless there has been another update I don’t know? I think the issue likes with the oil lines to a degree but also the seals failing, and road debris damaging them. Mine were too corroded to be redone by a third party PaulJC84 said: I saw Porsche specialist Weissachuk post on Instagram yesterday that they were fixing a 991.2 with a turbo failure.

bosshog said: Wonder why the Turbo/S models don’t seem to suffer from this? Thought the same thing myself. Must be a different design although I think corrosion to some degree must still affect them unless they are more covered and the car has better cooling?

More protected location, but all the fasteners are still rubbish and a nightmare to change. Things still go wrong!

This happened to our 991.2 5 years ago. It was a 16plate car on only 3k miles. Lots of smoke on start up. Then had boost pipes come off, and limp. Trailered to Guildford. OPC Guildford changed the oil lines, but but that made zero difference. We then told them we were going to drive 2k miles across Germany, they said go for it, no problem. Once past Aachen, the second time I used over 1/2 throttle, we had a big POP and the entire Autobahn (both sides) was obliterated by a what looked like a Saturn 5 launch. I knew it. We limped to services and parked it up. Porsche warranty / recovery were great though, and we were given decent cars for our trip. Aachen OPC were 5km away, so it was dumped there on a Sunday. They then replaced both turbos and all lines and communicated with us throughout. The warranty also covered our costs to go and retrieve it two weeks later and drive home. That was 5 years ago today, so funny I should spot this thread! It was fine for the next 10k miles until we sold it. This was the week we bought it. https://youtu.be/EZ5MghqN6Ko?si=93u6kJa7BQaEQW55 This was starting it to drive it onto the trailer at Aachen. https://youtu.be/xs3b3G20AkI?si=tCmdVzDIWN_ha-I8

bosshog said: Wonder why the Turbo/S models don’t seem to suffer from this? I was tolld when I had my turbos replaced on my T that there is a one way valve on the turbo/turbo S design which stops the oil being drawn back into the turbos under high pressure change events such as upshifts at full throttle. This one way valve isn't present on the lesser models and over time oil is drawn into the turbos and that's what can cause the failure. There are apparently updated oil lines which prevent the oil flowing back into the turbo. I don't believe it's anything to do with corrosion or mounting location of the turbos As an aside Porsche were very good at replacing both turbos under warranty, car was 5 years old with 30k miles on it. I've had a turbo fail on two other cars (from different brands) during the original warranty period, I think keeping the warranty on the Porsche is a no brainer knowing the costs associated with fixing the thing.

Grantstown said: I'm having a full clean up and lanoguard as well, so that should help with the protection issue. YMMV, but I would not be spraying Lanoguard underneath my 911. Firstly, it's a s tty product made of sheep extract that needs regularly topped up (Bilt Hamber have far better equivalent products), and secondly it results in a layer of bukakke'd black gunk everywhere on the underside of the vehicle making future maintenance more difficult, looks horrendous, and shouldn't be put on anything turbo/manifold/engine/oil-line/exhaust related anyway. Having seen the above pic of the location of the turbos on these cars, I just wouldn't be driving them in UK in the winter and especially not when salt is on the roads. Other than this there's simply nothing that can be done to stop accelerated corrosion of the turbo, fixings and related components given the location and our climate.

Grantstown said: More protected location, but all the fasteners are still rubbish and a nightmare to change. Things still go wrong! I don’t understand why they didn’t do the same location for them all considering the Turbo / Turbo S has a bigger engine, I think I’m right in saying? Yes it seems all fasteners etc on the Porsches aren’t great. I can’t believe they don’t even use stainless screws when the important components are so close to the floor. But yes all cars go wrong - but with Porsche to expect and be offered no help with a car with a still high value compared to their new SUVs even isn’t right . With a golf, Alfa yes but a company making as much money as Porsche, wanting people to buy 5 Taycans to have a GT3 RS or what not I don’t think helping out loyal and reoccurring customers a big deal

Can’t believe it was 5 years to the day. I watched your videos on YouTube quite early on during my information finding process. Thanks for uploading those to help us all with issues.

Did your car have the issue out or warranty originally? Personally I agree, and think it will just keep happening again and again and going my a previous post on here the 992 possibly suffers the same issue. A car only to have under warranty and not to be a daily driver - even though I practically daily mine. Weissach after inspection offer a really good warranty and is what I have on mine now. So speak to them if you are out of your Porsche warranty and near to Cheshire. Abtj said: Both my turbos (2018 GTS) were changed last summer after a protracted battle with Porsche.

Even if it’s in warranty & want to go on a few euro trips like I wanted and still want to do - it’s a big worry with or without warranty. You go on these trips to enjoy ‘your’ car not the hire car your given in the circumstances of something going wrong. a macan or cayenne Porsche has lent you is a lovely car but to enjoy the alps or what not you want a sports car and a relaxed trip & without inconvenience. If you have spent as much money on a car any 911 fairly modern you shouldn’t have these worries in your head.

Yup, I had a reminder pop up of our fun day on the trains lol. Our take aways from this were….. 1. Cardiff OPC sold the car in that condition. We collected in drizzle annd only spotted the clouds of smoke next day. They encouraged us to both in the car, before we started it to leave! “We’ll film you getting in and leaving and sent you the clip later” No they won’t! It was a second hand car like any other, so should have been independently checked by a 3rd party before we travelled I now seen some of the same from Reading. 2. I realised Cardiff don’t prep their cars. We had four different tyre pressures, found coins and receipts in the car. Also when we lifted the frunk ancillaries cover, it was FULL of pine needles and the drains were clogged with tree detritus / brown goop. We really wanted to keep that car / spec, so were happy that Guildford said they’d sort it. 3. There is still a reluctance to do what’s required, and to test an interim fix, in the hope the car gets driven gently and covers next to no miles until out of warranty. 4. The extended warranty and especially European recovery were amazing, on Sunday too! Even swapping cars to come back to the UK in `franc on a Sunday was a breeze. The German OPC experience was also VERY different. We were extremely lucky and had great weather throughout the drama. 5.Then learning about the issue and realising the designers were stuck for anywhere better to put the turbos. Fortunately for us, we were visiting family in CZechia, so didn’t mind a car down grade. (We weren’t on a meticulously planned euro hoon of a lifetime) An A6 diesel wasn’t exactly fun, but was still fast, and arguably a better car on the Autobahn and halved our fuel bills No way it’ll put me off the brand (we’ve had four since) but realise the dealers are often the same as dealers ‘down the arches’ When it comes to getting cars out and hiding issues until on somebody else's dollar, they can be quite ruthless.

rjh_36093 said: Even if it’s in warranty & want to go on a few euro trips like I wanted and still want to do - it’s a big worry with or without warranty. You go on these trips to enjoy ‘your’ car not the hire car your given in the circumstances of something going wrong. a macan or cayenne Porsche has lent you is a lovely car but to enjoy the alps or what not you want a sports car and a relaxed trip & without inconvenience. If you have spent as much money on a car any 911 fairly modern you shouldn’t have these worries in your head. Obviously totally up to you what you feel comfortable with but to put the use in context I did 15k miles in mine in the 9 months following the Turbo replacement, never saw another puff of smoke and it didn't use any oil.

Iknownothin said: Why not just extend the warranty and not worry about it? Fighting with Porsche was an awful experience

rjh_36093 said: Did your car have the issue out or warranty originally? Personally I agree, and think it will just keep happening again and again and going my a previous post on here the 992 possibly suffers the same issue. A car only to have under warranty and not to be a daily driver - even though I practically daily mine. Weissach after inspection offer a really good warranty and is what I have on mine now. So speak to them if you are out of your Porsche warranty and near to Cheshire. Abtj said: Both my turbos (2018 GTS) were changed last summer after a protracted battle with Porsche. I asked for written confirmation that the replacement was an ‘upgrade’ that would stop issue again and received response that it was a like for like replacement. Got a full two year OPC warranty extension as way of apology. I love the car so much but will replace before warranty expires as it will happen again in my opinion…. Some of the comments about water ingress makes sense to me given turbo location. I now keep in garage and don’t drive in the wet. I do find it odd to have to be so concerned about such an expensive failure on a modern car. In my case, my car had about 20k miles on and was about 4 years old. I’d bought at OPC about three months earlier when it started smoking (so full warranty). By the end it smoked every time I pushed on i.e. >70mph. I took numerous videos and kept taking back to Porsche. I can’t remember but 6 or 7 times over 12 month period I was told that they couldn’t recreate the smoke and therefore nothing could be done under warranty. They did however change the oil lines twice. I raised to Porsche UK in the end. They were evasive and continually tried to pick holes in my story - I have written responses telling me that legally they were not able to road test above 70mph and therefore couldn’t investigate further. In the end I took legal advice and submitted to the supplying OPC. Within 48 hours the car was recovered and both turbos were replaced. The final amusing chapter came the following week. I was in France on holiday and got a call at about 11pm from Lincolnshire Police. They had been called by the local Tesco as my car had been abandoned there earlier. The driver returning the car from Porsche to mine had run over his hours and therefore parked up at the front of Tescos and given the key to the customer services. After no one returned for hours, the Tesco staff had got worried, called the police who then called me. The end result was Lincolnshire Police recovered my car to the station and I had to drive there and get it. Somewhat took the edge off the experience. I forwarded the police emails and photos to Porsche who called me up in a bit of a flap and offered a two year warranty extension. As such I keep telling myself to get rid but I’m just too lazy, I still love the car and I hope that if anything else went wrong I might get better support.

My Father had massive issues in 2022 with his 991.2 GTS Targa around 15-20k miles. The car had a complete meltdown while in the Spain resulting in it dying at the roadside. After weeks at the Marbella dealership with technicians trying everything, along with back and forth to the factory and UK mechanics, they tracked it down to the DPF’s and turbo’s. End result was all the Cats and DPF’s being replaced, along with one of the turbos - all under warranty. Car was eventually transported back to the UK after 2-3 months sitting static in Spain awaiting the parts. Needless to say he was pretty unimpressed with the whole situation and Porsche GB put their hands up and offered him a package by way of apology. He’s moved onto a 992 now and really likes the car and thinks the general quality is significantly up on the 991.

Not sure if already covered but my car’s been in with an OPC for a couple of weeks now and as nobody seemed to want to update me I called the service manager to find out what’s going on. My symptoms were quite a bit of oil usage, occasional smoke (one time significant smoke) and a visibly oil leak on one side. Apparently the fix is to drop the engine to replace the oil feed pipes (apparently an upgraded part is used). Then everything’s cleaned up and put back together. They then test the car to see if it still smokes and if it does and does so for at least a minute, Porsche will authorise replacement of the turbos (video evidence required). Then the car gets taken apart again and they do the work. The service guy suggested that even if they. Couldn’t get it to smoke during testing the majority of cars will start smoking again resulting in a return trip to the dealership to get the turbos replaced. It is creating additional work for dealerships as there’s only so many dropped engines they can accommodate and given that most cars do get the turbos replaced it means the service centres are wasting so much time dropping engines and putting them back where the work should really all just be done in one go. I guess the accountants at Porsche still think there current process is the winner though.

Anyone seen Petrol Peds video on this issue?

johnny senna said: Just wanted to let folks know about what has happened with my 992 Carrera S. It's on a 69 plate, I took delivery of the car brand new in January 2020. Quite early in the car's life, I think between 1 and 2 years old, the dashboard flashed up an engine warning telling me I had reduced power and that I needed to drive to a workshop. I did so and the OPC replaced the left side turbo. Then recently the same warning light came on the dash. The OPC have now replaced the right side turbo. The tech report states: "Turbocharger replacement on assembly bank 2. Wastegate arm cannot be cleaned up and greased".... (Sorry for reviving an old thread) Was there a noticeable symptom? I've got 69 992S that did the "Reduced Engine Power" warning, which went next time I started the car. I feel like it doesn't perform the same since. Been in to Porsche a couple of times. No error messages, logs etc. 2 techs have driven it and said it seems fine. Lacking any go at lower revs. Manual 4th from 40 is poor, 5th from 40 is almost non-existent. In auto, at 30 in 5th, foot to floor downshifts to 2nd, but takes over a second before speed starts to increase. Anything more than a very gentle accelerate ends up shifting down to 2nd. Delivery feels like an old school turbo, nothing while it builds up, then sudden power.

Sad to say the smoke issue broke the spell for me after four years. Three times it went in for investigation. Twice it had new oil separator pipes installed. Then the first day of a driving holiday last month, big smoke, dashboard lit up and car immobile in a not so convenient location. To be fair, Porsche Glasgow did a brilliant job of turning it around in four days with new everything this time including two new turbos. Service manager there was brilliant and was far more open about the issue than I’d experienced before. His reassurances aside, I can’t be doing with looking for smoke every time I start the car up. I sold it today (with full transparency). All done under warranty. Porsche seem happy to just roll with it. Suspect I’ll be back, but I’ll be taking a break from 911s for a few years.

Hi Ted, trust you’re good? While I can keep a Porsche warranty I’ll be keeping mine, after having both sorted I’d hope that I’d get a few years of decent motoring.

So I picked up (what was to me my dream car) an approved used GTS - 38k from Porsche Swindon a few weeks ago. Purchase experience was fantastic, could not fault them Within the same day it was making an odd noise - to me what sounded like an alarm beep from the engine. Took it back, was told it was a loose breather pipe on the turbo. While there I paid for new rear disks and pads as I felt they looked tatty and a bit shot to me (but by all accounts within the tolerances for an approved car) To note, I paid for an extra third year warranty at POS for peace of mind. Added tyre insurance and wheel damage insurance. This is a car/spec I have been waiting for around 3 years to strike on. I took it then to my detailer - had it properly tidied up and PPF'd etc. From there it went to Litchfield to fit a Milltek Titanium exhaust as the sports exhaust to me looked tired and corroded underneath when I saw it up on the ramp at my detailer. Litchfield took the exhaust off and discovered the turbos had oil in them and to call Porsche straight away. I did, spoke to the after sales manager who showed the image to the technicians who said they would expect to see this much oil with this age etc (the car is 3 weeks old to me at this point less than 500 miles mostly back and forth to get stuff sorted from where I live and nothing more than motorway speeds). They said wipe the oil away and fit the exhaust and carry on, advised Litchfield to carry on and picked it up Saturday. Drove home, popped to Caffeine and Machine to see a friend and had a spritely drive home. Barely 20 miles of spirited driving on A/B roads. Parked at the pub, had some dinner and came back to the car. Started it and filled up the pub car park with plooms of white smoke. Car has used 1 litre of oil in about 200 miles and on cold start this morning spat more smoke out, had this residue in the exhaust and what looks like a load of oil (both sides) spilt on the floor below the pipes. I am taking it back to Porsche Swindon tomorrow. I am due to go to France on the 6th May for a pre arranged car trip with some of my friends following the death recently of my wife. The reason I bought this car, to try to put behind me the last 5 years of stress and dealing with cancer. Genuinely gutted and no idea what's next. Litchfield who used to look after my Impreza's 25 years ago when I was last 'in the car world' have been superb with me.

Be careful, changing the exhaust to non standard can invalidate your warranty.

Hi Eric. I hope that after all that you have gone through you get the car properly sorted asap and can enjoy some decent smiles per miles!

Really sorry to hear this Eric I hope you get it sorted in time for your road trip.

What a pain in the backside for you. You’ve done the right thing to call them straight away and with a bit of persistence you’ll make it their problem and most likely get a new pair of turbos and oil lines.

Eric - very sorry to hear about your wife's illness and passing. I do hope you get this resolved quickly or at the very least they give you a great car to go on that trip with. Ted - when you say your OPC was open about the issue, is there anything new you can share? My GTS is currently ok at 25k and I'm sort of ok with the warranty resolving any issues like this. However, if they shared the root cause with clarity I'd be keen to know where it sits. Clearly it's not the oil separators so is the issue the turbos themselves?

The service manager in Glasgow explained it to me, but with his Scottish accent and a few terms I wasn’t familiar with, it went in one ear and out the other. He said he’d not seen one come back after having all the work done. Absolutely sucks. They should get this nailed and provide genuine reassurance. I’ve bought an M5 instead.

I have just had the Litchfield oil catch tank kit delivered and plan to fit it this weekend. Any feedback from anyone else with this on their car. My new to me 991.2 C4S has dropped a bit of oil and the team at Parr in Sussex don’t believe it to be anything to worry about, as the separator passes all the tests.

I’ve been looking for a 991 GTS. I drove a base spec red one in Sudbury last week. Lovely but too much for a base spec car. I had a look a high spec Blue one but the garage selling it aren’t really very serious. With all of these turbo issues, perhaps I’d be better off with the .1 GTS but having driven the later car, it really does feel like a step forward… is the only option to get a car with a porsche warranty and the let them pay for fixing the inevitable problems?

The .2 do feel quicker with the big uplift in torque plus 30hp of extra power. Having said that, Porsche do understate the power as mine was on the rollers at Litchfield & produced 470hp- completely standard GTS .2? However, a warranty is very important until the car settles down . I extended the warranty & it has paid for itself. Edited by griffdude on Thursday 14th May 18:08

I've had a dot 2 GTS for 6 years and 30k miles. I have run it without a warrenty since the three year Porsche one ran out. No regrets as it's a mega car. They need to be driven and exercised regularly and allowed to idle for a couple of minutes before switching off. No oil burnt, everything is cool. As ever, with these things, you only tend to hear about the failures. There are many many cars that don't have turbo issues, but you won't hear about those.

PorscheGirl said: is the only option to get a car with a porsche warranty and the let them pay for fixing the inevitable problems? If you want to not worry and just enjoy the car. These cars depreciate very slowly compared to normal run of the mill cars. Just look at the cost of the warranty as part of your running cost. The overall cost of ownership is still low.

I was behind a nice English-registered 991.2 at the Nürburgring for two warm-up laps. On the first fast lap, it started billowing smoke, and that was the end of his trip. Real shame.

On forums this problem is as common as death and taxes, but there have been around 100K 991.2s with turbos and more 992s with the same set up. It’s certainly not a guaranteed early point of failure, but it’s an exposed engine bay with the turbos and their associated feeds very low down. When you look underneath there’s a huge difference between an example that’s been used through the winters versus a summer car +\- underbody protection etc.

The Porsche warranty is incredible value compared to other manufacturers, especially when you look at parts and labour prices. A year’s warranty cost is about four hours labour and if the car isn’t driveable you get a loan car straight away from Porsche GB without having to wait for an OPC loan car to become avaialble.

My car is used almost exclusively in the dry (although I did get caught out in the rain yesterday) and therefore is extremely clean underneath. I guess this could be a factor. When I see some other 911's of a similar age on ramps I am often staggered as to how comparatively dirty / rusty they are. As ever, buy the best example and look after it.

I had one from new (4GTS) 2018-2025. 40k miles, no turbo issues and I would let it run at the end of a journey for a minute or 2 as recommended for many turbo cars. I did renew the warranty but only ever needed it for a couple of sensors replacing.

It looks like Genome has a preventative solution https://genomedesign.co.uk/products/porsche-991-2-...

My 991.2 T had a turbo replaced as a precaution; a bit more oil than expected noted (long story) during the eight-year major service. 27.5K miles, no symptoms and six years sympathetic driving from me. Thankfully, all covered by extended warranty. I wouldn't run a Porsche eligible for extended warranty without one.

griffdude said: It looks like Genome has a preventative solution https://genomedesign.co.uk/products/porsche-991-2-... I've had an oil:air separator fitted to my car. It's a shame that the emission controls have to be at the expense of reliability. I do feel more comfortable knowing that one mechanism of failure has been mitigated. I don't think that it solves the oil feed issues though, which is a different mechanism. Still, it's an inexpensive item to fit. Turbos are a potential point of failure on any car over time. If mine go in the future I'll have upgraded items fitted as I continually look to improve the car.

When the turbo(s) are replaced are they like for like? If so, only a matter of time before it goes again. I had a 991.2C2s and when the OPC did their 111 inspection they said - "misting from turbo, no need to replace but keep an eye". Hopefully the turbo went like Thermite as it was stolen shortly after anyway!

Sold mine last week. Never had any issues other than coolant leaks and a new water pump. Great car but I didn't use it enough to warrant the money being sat there so decided to put it somewhere else. Turbo issues in the background did take some shine off but the OPC warranty was enough for me. Oddly it couldn't be sold without one being on it so read into that what you will.

Can't blame them considering the cost of resolving it and if anyone is running a modern turbo Porsche out of warranty they're braver than I was.
