The flywheels are recomended to be changed after the second clutch you don't want to be damaging it any more.

What's the best way to test a clutch to see if it's slipping as I suspect mine is on it's way out?
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.

Did my clutch, fuel filter and RMS the weekend.
Easy to tell, drive at around 30mph in 6th, give hard throttle, if you get the initial rise in revs before the car speeds up then thats the 1st signs.
Had any fishy smells?
The standard test is to drive uphill in a higher gear than normal. If the revs rise and your speed doesn't pick up, your clutch is slipping.
Edit: beaten to it. Went for a quick coffee
Related point. Im looking at a couple of 996TTs. One has 44k miles and Ive asked if its had a clutch replaced. Guy handling the sale is doing so for his boss and is getting me the relevant information but suspects its on its first clutch.
Cant imagine a turbo managing 44k miles on one clutch surely?? Dont intend to even look at it if it still is on its first on the basis that Id be putting one in soon. Correct or not?
Interesting that the other day you mentioned that your pedal stuck halfway.
Obviously related. Sounds like a definite clutch failure is imminent.
My guess is the friction plate is seizing on the shaft.
Not sure if Richard H has ever seen anything like this but I have seen crushed clutch hydraulic lines in the past. It is the Blue 6mm thick pipe that travels under the NSF wing, down and along the passenger side sill.
If crushed it will cause heavy pedal and slipping problems.
Thanks for your input Lloyd, but when I pulled the pedal up with my foot it came back without too much pressure. If the friction plate was sticking then surely it wouldn't have come back, the engine was also driving the wheels via the gearbox at the time. :?:

Drive along with a steady engine note, toe the pedal till it just starts to move.
If it revs up you have had your moneys worth.
A full clutch will bite just off the floor.
Is the car becoming snappy at the lights when you try move away?
RMS,IMS seal- clutch.
Good menu.
All the above threads are good diagnosis may I add!!
My Porsche Tec told me these can loose drive all of a sudden when they are on the way to bear metal!
Promted me to take action.
I do trust him!
That's right, it would be easy, it hydralically SP? assisted both ways.
I bet when it gets striped down you will find the plate is not moving freely on the shaft and you thrust release bearing is knackered.
Order:
3 part clutch kit
6 plate mounting bolts
Set of flywheel mounting bolts
Upgraded rear main seal
Advice:
Take it easy, avoid slipping as much as possible. The last thing you want is big Blue spots on your flywheel.
Adeymars, I recently found that I needed a lot of revs to get over a speed bump, also the same when reversing up a steep incline. Then my clutch pedal got stuck half way - in my mind it was pointing to a failing clutch...........
Ray
I would go to your trusted indie and let him have look and a drive.
Lloyd has a good point. The flywheels are recomended to be changed after the second clutch you don't want to be damaging it any more.
(TT anyway, I found this out after alot of enquiries.)
You should here the engine note rise if you are loosing drive. The rev counter should raise up with out any more forward momentem.
You should not have to fight to get over a speed hump,just cringe thinking about the though of your poor control arms!
The clutch plate is designed to wear out on the pressure plate side first rather than the flywheel side for obvious reasons. Some solice.
I think Lloyd has it with the bearing suggestion.(stuck pedal)
Good luck but don't delay!
You broken down at the side of the road will not do our image any good!
Pork on!
