I went to see a 2003 996 C4S today as a possible change for my 996 C4.

These are separate views of the same evidence. Frequency alone does not establish a fix, and these counts must not be added together.

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.

POST 1 / ORIGINAL POSTEROriginal post

I went to see a 2003 996 C4S today as a possible change for my 996 C4. It's a tiptronic (which is what I need), but when I started it and blipped the throttle it wouldn't rev over 4000 rpm. Didn't matter whether it was in Park or Neutral - it just wouldn't rev higher. Is this normal? Is there something clever that only allows the engine to rev higher if you are actually driving and in a gear? Or does it mean there is a major problem?!

POST 2Original post

Yes, there is a rev limiter when the car is in neutral on 3.6 996's.

POST 3 / ORIGINAL POSTEROriginal post

Thankyou Richard. I now feel suitably stupid, but relieved and better informed. Have also just noticed that your car is not dissimilarly priced to some C4S cars, which brings a whole new dilemma to my new car search! Is it wrong of me to have a modified 944 Turbo AND a 996 Turbo (which would be immediately remapped)?

POST 4Original post

It took me a while to find that out too, so don't feel stupid. Not wrong to think that way IMHO. Two very different cars and character. You'll probably find the Turbo cheaper to insure than a C4S too. Crazy, I know, but many have found it so. Other running costs are similar, with the exception being a spark plug change.

POST 5Original post

you're right Richard, my Turbo S is significantly cheaper than my C4S was, just insured it this week for £407. [ ]

POST 6Original post

Hi Ashley, £407 sounds amazing. I'm paying more than that on a C4 Cab. Who are you insured with??? Regards Wills
