One of the jobs was the clutch replacement which would slip under heavy acceleration and smell dreadful, this was replaced approx 3 months ago.

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

Hi everyone I recently joined the forum but never posted a question till now. I have been hiding behind my keyboard reading all the other informative posts and checking which ones relate to me. I purchased my 98 carrera in Aug 2015 and inherited a long list of faults of which I am currently going through with a current tally of £3k. One of the jobs was the clutch replacement which would slip under heavy acceleration and smell dreadful, this was replaced approx 3 months ago. I have pushed the car several times since with no problem but tonight was different. I accelerated at full pelt with the tc on and no problem, then I turned the tc off and duplicated my run but this time the clutch pedal dropped down and stayed down while I was accelerating in second gear. I stopped immediately and the pedal returned and I noticed the smell of a burning clutch. The car drove fine on my way home even when I pulled off in second gear there was no slippage. So if anyone has come across this what was the remedy and if this is new to all then any suggestions. Appreciate your time.

POST 2Original post

Keiran!! I can't say I've heard of this before, but from what you have said I would suspect that the release bearing stuck on that occasion. Another possibility might be the hydraulics. Is the fluid level OK?

POST 3 / ORIGINAL POSTEROriginal post

Hi Richard My capabilities peak at filling the washer tank with water. Sorry I am not mechanically minded so it may mean a trip to the garage. Another issue that may be linked to this scenario is that the clutch pedal is not light and when in slow trafic it is quite difficult to maintain a slow speed without over revving, and when I dip the clutch in first the revs increase for a split second. Thanks

POST 4Original post

How old is the clutch / brake fluid? if your acceleration runs have been matched by equally heavy braking it's possibly that your reaching the boiling point of the fluid in the clutch system(by putting heat into the fluid with the brakes) or that your clutch hydraulics need bleeding. I am assuming it was a complete clutch change and not just the friction plate?

POST 5Original post

The heavy and difficult clutch action might be the pedal booster spring, and this might also cause the pedal to stick.

POST 6 / ORIGINAL POSTEROriginal post

Clutch was replaced approximately 3 months ago and the car only gets used at weekends. As for braking heavy that never happens. Because of the smell after the event I do not want to try and replicate to see if this was a one off. As far as what was replaced I only know it cost £1k ( Sachs clutch ) and carried out at an indie.

POST 7Original post

Can't say I've had this problem on my Porsche, but it sounds consistent with clutch release bearing problem - they ought to to, but don't always, replace them - suggest you check to see if they did.
