I've had 2 dynamic engine mounts fail, the nearside exhaust actuator fail and then the nearside exhaust replaced after the exhaust valve jammed.

Porsche replace an entire back box BUT many seem to check the actuators frequently by manually moving them and also grease the actuator rods to prevent/reduce likelihood the happening.

Coverage and how to read this overview

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.

8 eligible posts · 0 unverified posts · 1 discussions match the subject in their title or opening post.

  • PistonHeads: 1 discussions

0 evidence records excluded for query context · 0 excluded by outcome qualification · 0 adjusted by outcome qualification.

0 acknowledgements have no verified action link; they do not establish a repair result.

POST 1 / ORIGINAL POSTEROriginal post

I have been doing a good amount of swatting up on the 981 and below seem to be the known/common issues. I have all but decided i won't go for a Porsche warranty myself (instead put money aside for issues) as the car I am buying was just serviced by an indy last month. The first 2 services were OPC and second 2 the same porsche indy, only 2 owners etc so a strong history. - Dynamic engine mounts that come as a part of sports chrono. £1200-1500 per side all in. - Sticking exhaust actuators. Porsche replace an entire back box BUT many seem to check the actuators frequently by manually moving them and also grease the actuator rods to prevent/reduce likelihood the happening. - Steering racks have been known to fail but this is very rare. Up to £3500 to replace the steering rack. - I have just read about PDK failures but there doesn't seem to be a lot of info in terms of frequency/likelihood. Very expensive to replace! Any thoughts? Stu

The only one that is bum twitchy is the pdk but very little info on it.

POST 3Original post

anonymous said: [redacted] Specialist can now rebuild them. Porsche don’t ‘fix’ anything, they just swap out defective parts hence under warranty a PDK is. Full unit replacement north of £10k

POST 5Original post

Dont forget the flaky PCM! Boards fail inside and your looking at around 2.5k from Porsche or 1k+ to attempt to repair it. You will notice there are always a few on Ebay - usually ones that have been repaired and now being re-sold. I had mine got - system just re-boots constantly. Have a look on line under PCM rebooting.

Rear axle carrier recall. See other thread. Mine unaffected. Heater fan sticks. Mine did this just once, years ago. Self healed. Brake pedal bush. Mine unaffected.

That's in just over 5yrs in ownership.
