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.

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

  • 911uk: 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

Hello everybody...I've been reading with interest (alarm?!) at the thread about the 996 engine problem and Porsche's response to it. Rather than continuing on that same post, I thought it would be interesting (and scientifically worthwhile) to ask 996 owners on this forum what problems (if any) they've had with their own cars. To make it accurate, please reply with the following info: 1. What model (and whether a 3.4 or 3.6 engine) 2. Age (Model year and registration year e.g. 1999 on 'S' plate) 3. Mileage covered to date 4. Original Engine? 5. If original engine, any major mechanical problems, what was done, how much and did Porsche GB help out financially? 6. If NOT original engine. What mileage did it fail at? How much was the bill to fix it?! Did Porsche GB assist financially? 7. Any other comments thats are relevent. If we get enough responses to this, it may help people in the future decide whether or not to buy a 996: it will (hopefully!) reassure those 996 owners (myself included) as to the likelyhood or being financially "spanked" in the future by their car! And maybe, it might help Dr Mahen Nadarajah in his battle with Porsche GB with his own car. Please take a few minutes to take part as I'm sure the results will be appreciated by many.

So far 11 cars reported on, and 4 RMSs/engine replacements. Not a representative sample but not encouraging. Decompressing should change his moniker to 'Depressing'. Migration info. Legacy thread was 29393

1. 996 C2, 3.4ltr Tip, LHD 2. 2001 'Y' Reg 3. 42000 4. Has original Engine 5. In for 48K service yesterday. Porsche called me today. RMS just about to start leaking (oil buildup). High-pitch horn needs replacing. Fortunately these 2 are covered by the extended warranty (already paid for itself). Fanbelt needs replacing, as do front discs, and soon the front tyres as well. 6. N/A 7. I knew that Porsche service can get costly, but ouch! However, when I drive it, it is easy to forget! Nik Migration info. Legacy thread was 29406
