Help diagnose engine/clutch vibration

[smithk3933]

I've recently acquired an 02 C4s with 38k miles and have a question regarding a vibration. I feel the vibration in a couple of ways. If the clutch is fully depressed, disengaged, and rev the engine to 3-5k, I feel the vibration through the depressed clutch pedal. Also if while driving along, and just partially depress the clutch, not to the point of disengaging, I also feel a vibration. It definitely doesn't feel as smooth as my previous 95 993.

Any ideas? I was going to bleed the clutch this weekend, but wouldn't think this would help since it has the vibration with clutch disengaged.

I would have said air in system (bleed clutch). This could be cus your slave or master cylinder is on way out. Any 'binding' as you depress and release the clutch??

I would certainly not call the overall clutch pedal action smooth. The car still has a bit of CPO remaining so I might take it by the dealer and see if they will do a test drive. I would love to be able to drive a similar model to determine what a normal feel is.

See my chains of questions on this problem. I have almost exactly the same problem. You clutch is on the way out, warped clutch disc or pressure plate. Shortly after that happened we believe the diaphragm spring died and the clutch started slipping. Not sure whether this is a common failure sequence.

Let me know what quote you get for a clutch job. So far, the local quotes varied from 3kUS$ to 1.5kUS$ at P dealers.
