I'm about to do mine again as the bearings i used didn't hold up.

Could understand certain other built to budget Asian car manufacturers but I wouldn't think Porsche would ever do this (unless it was the North American branch with their bad public relations lately)

But for everyone else a $20k repair on a car that is worth $30k (I'm looking at you Golfs) is a write off.

I reckon 25K is way too long between oil changes anyway.
These are separate views of the same evidence. Frequency alone does not establish a fix, and these counts must not be added together.

Counts describe captured discussions, not unique people or a diagnosis. Author identities are not reliably stored. Exact duplicate evidence is counted once across matching discussions; one discussion counts at most once per action/state. Multiple repairs reported together remain a combination. Suggestions and failed attempts do not establish a fix. Matches cover whole discussions and can include related faults, model variants and incomplete threads.

So Porsche Melb wants me to service my car yearly and not every 2 years as the manual says.
Now I was going to do it yearly anyway but I was interested in what they would say, so I asked and got this reply:
Hello,
Thank you for the email. With regard to service on the Porsche, Australia is a "B Grade" fuel market and as such, it is necessary to service your Porsche every year or 15,000 km's. Whichever occurs first. If your manual states every two years I would suggest that it may be possible that the incorrect service book is in the vehicle.
In Europe and North America the service interval is every 2 years. Was your vehicle originally sold in the U.K?
So.... Aus is a B Grade Fuel market??
Probably referring to the Sulphur content of Australian petrol. Whether this actually means you need to service more often I simply don't know.
Japan / EU = Low Sulphur
US / AU = High Sulphur
I could understand changing your oil yearly but to blame it on the fuel is stupid. The fact we have poor fuel at the pump has more to do with the crap that ends up in the fuel at the servos more than anything else. The number of times I have had water in a tank of fuel by filling up at a Shell servo is nuts.
I filled up mine at a shell servo once. My knock sensor went crazy and pulled so much timing. I can actually show you graphs in boost curves how bad the car drove.
drained it and put BP back in. drove like a dream again.
when i got my motorbike license the dealer warned us not to use shell premium in their triumphs as it made them run terrible.
never understood it myself as it all comes out of the same refinery?
I haven`t given the newer shell the chance to ruin my day, but the original v power or v max or whatever it was called, if left in the fuel rails too long would evaporate into a jelly that required total dismantling and cleaning of injectors, rails and even fuel lines,lots of swear words and many hours were spent vowing never to darken their forecourt again.
Can someone tell me how cars went from the traditional 6 month / 10,000km service interval to 2 years / 15,000km intervals? Holden/HSV added a bigger sump to their LS2 and that was enough to lengthen the service interval. So more oil means it degrades slower? I can't help but think that it's all marketing that could potentially shorten the lives of engines in the long run. That wouldn't have any effect on the manufacturer as it would be way out of warranty by then.
If PC used that font in their response to you, then I'd automatically assume their response was full of shit!
Hmmmmmmm. I generlly use Shell followed by BP.
I can honestly state that I have NOT had any bad experiences with either.
I reckon 25K is way too long between oil changes anyway. That is of course if that's what Porsche intend to do on the shorter service.
Here are my logs:
First one is with BP ultimate (98)
Second one is with Shell Vpower (98) - at 4k rpm you can see a flat spot where it suppose to be at a ~345 and increase to ~355 at 4250rpm but has dropped and stayed at ~320 and stayed there until 4250 rpm.
****Note the red and blue lines have changed sides between logs****
Build tolerances, materials and lubricants have improved over the years. Better engineering means engines run cleaner and with less wear. So service intervals get longer. Well that's the theory anyway.
I either go for Shell or Mobil then BP. Don't even remotely think about Caltex or Safeway and other independents as I've had some pretty rough running engines out of them in my Honda Civics.
Orion - Service interval sounds pretty standard to me, my 996 is doing changes at 10k or 6 months
By the book it's 24 months, 30,000 km
I know it's better to get it done more often, I was just amused at the reason the service guy gave, i.e. Aus is B grade fuel.
My take on the long service is...
It's perceived to be a big hassle to the public to take the car in for a service, so the car companies make it longer and longer. The car companies also bet on the average owner not keeping a car for longer then 5 years... so the engine itself can die after 10 years.
So hence it's okay to have longer service intervals cause hey the car is design to be obsolete in 10 years.
That's my 2 cents on the long service interval.
Could understand certain other built to budget Asian car manufacturers but I wouldn't think Porsche would ever do this (unless it was the North American branch with their bad public relations lately)
Works in a manufacturers favour. Car blows up at 10 years, that buyer was never going to buy a new one anyway. So the reputation amongst new buyers stays sound, and the manufacturer gets to sell more cars.
Geez you make it sound so bad!
If anything major, rod and crank bearings and new seals. Piston rings if worn out enough but i'd change them anyway.
shes good to go another 200,000k's
I think it's old Porsche Vs new Porsche....
Old Porsche you figure you can drive forever.
New Porsche = built in obsolescence especially with all the electronic gizmos.
will a PDK last 30 years? find out in 25 years time?
:-)
But hey that's just my cynical view.
But that's just like saying how long is a piece of string.
for example when the transition from mechanical fuel injection to electronic. i bet it would have been the same thing. 25 years later and the moronic systems still work, and some have solder join issues.
Only time will tell
Can't agree with you more there Pauly. There's also always the case of replace it with a part which is newer and better. I bet there's a tonne of 30+ year old cars on here which have swapped out an old part for a newer more modern retrofit/replacement. Although the rate of obsolescence for things has definitely increased these days.
Increased service intervals have been seen as a competitive advantage by manufacturers when trying to sell cars to fleets. Fleet sales depends on low life cycle costs and if it's possible to defer maintenance that's extra sales.
Here's a good example.
I had to rebuild my injector harness the other day. Every single wire was frayed next to the pin, so if they happened to twist, my engine would shut off. Which was the case last week.
I can see the 964 and 993 owners slowly getting to the point of wires up-to their life time limit.
For the 944 and a few 911s who use the motronic computers, now there's replacements that run cooler and with less components and expandable. tuneable too.
The 924/944/968 have torque tubes, and the bearing inside are 'not replaceable' and are not suppose to wear out. But they all wear out and you cannot replace them as they say.
PITA job but you can replace them, it's just hard to find the correct bearing as none fit.
I'm about to do mine again as the bearings i used didn't hold up. i will have to make my own carriers and fit better bearings.
So i believe with the PDK, they are rebuildable.. And im sure somewhere someone will write up a DIY PDK rebuild.
with the more electrics, they're just more sensors really, and OBD2 can pick up sensor failure.
Which is all ok if you're on the tools, but for those of us that aren't a PDK / S Tronic / DSG / DCT is currently a throw-away item. One that costs $20k (including parts) to get other people to replace.
Everything is fixable no doubt, especially if you have the skills, and probably more importantly time. But for everyone else a $20k repair on a car that is worth $30k (I'm looking at you Golfs) is a write off.
Kind of wandered off track here
workshops will likely start offering exchange gearboxes. send a rebuilt one out to you once they receive your original box. will not be too expensive by that time i'd say.
sleazius did you just point out why manuals are superior as a collectible car
In the case of Golfs you can buy a rebuild kit, manual and hopefully make some new friends trying to fix it for a lot less than 20k. Trust me, making new friends who can help out is always handy when you're not a spanner monkey.
That sounds like a good reason for the long service interval.
