Explicit resolution reports before identified causes, performed actions and suggestions. Within each level, matching component labels precede direct query mentions and inherited thread context; successful versus unsuccessful discussion counts, owner confirmations and independent discussion support determine order. This is not a probability of success.

0 original-poster resolution reports. Counts can overlap; they are not unique people or a success rate.

0 discussions have direct query context; 0 report a fix in that context. Other evidence may inherit the discussion’s subject.

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.

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

POST 1 / ORIGINAL POSTEROriginal post

My 3.4 996 C4S has been wonderfully reliable but yesterday started to smell a little sulfurous and today the "check engine" light came on... Is this something I can fix myself? It seems to run OK but will driving cause any serious damage?? Migration info. Legacy thread was 140890

POST 2Original post

Is it on or flashing? Mine has only come on once and it was a MAF sensor. Easy fix. Also coil packs can cause this, again an easy fix, but you would notice the loss of power. I would go straight to an OPC to get it identified. Migration info. Legacy thread was 140906

POST 3Original post

I would go to the nearest OPC at your earliest convenience to get it checked out for sure.....mine came on the other week and was reset after a diagnoses revealed a small amount of dodgy fuel....since then it's not come back on and been serviced and all is well Migration info. Legacy thread was 140909

POST 4 / ORIGINAL POSTEROriginal post

Thanks for the advice! Another trip to Autofarm.... BTW: The official diagnostic tool is really expensive, is there a cheap and cheerful generic diagnostic tool that would at least allow you to read this stuff off? Migration info. Legacy thread was 141042

POST 5 / ORIGINAL POSTEROriginal post

oops, meant to say that the light is on all the time suggesting emission issues. The engine runs fine with no misfiring, just that eggy smell on start-up...... :evil: Migration info. Legacy thread was 141043

POST 6Original post

sounds like the cat' has a problem Migration info. Legacy thread was 141051

POST 7 / ORIGINAL POSTEROriginal post

The nice man from the AA popped in and put his diagnostic thingy on,read the error as the mass flow unit. He reset the error, disconnected and reconnected the cables, restarted and it was all OK!! I thought these things reset. Migration info. Legacy thread was 141084
