Hello

Well after an event free 3 months(and nearly 8k miles!!) of tt ownership, I think my first major expenditure is due. I think that my clutch is shortly about to expire (judging by recent posts I dont think that I am alone). After the car is fully warmed up when I release the clutch I get a vibration through the clutch pedal and a `grinding` noise. It also seems that the clutch release is quite high. This mainly happens when downshifting from 4rth to 3rd gear. Does this sound like the clutch or anything else I should consider?

If I do need to replace the clutch it would be an ideal opportunity to upgrade. Seems the popular choice is LWF and GT2 plate. What are the advantages and disadvantages of the setup? Will it effect driveability? Any UK rennlisters recommend a source in the UK?

Thanks in advance
Ronnie

if you want to test your holding of the clutch go over to a hill and stick it in what 2nd or 3rd and try to go up the hill and see if it slips. Be careful of course, but this is what I was told is the definitive way to test if it's wasted or not. Clutch disc wise. It could also be glazed with both the pp and clutch disc, either from beating on it or by oil puking on it and cooking onto it. Sounds like you have the right idea about what you want for the upgrade though, check the archives there seems to be a fair amount of data about the options.

I would first look into the clutch slave cylinder. I've also read here about some sort of a kinematic clutch gizmo that may explain your symptoms. I hate to throw water on your clutch upgrade plans, but it may be something far simpler to fix. Sorry.

Thanks guys, car going in on Monday to the local independent.
Steve - if it is the slave cylinder then thats better, will spend the money on some other things Just have to upgrade the clutch whent the time comes (at 55K miles probably not too far off!)

cheers

Ronnie,

My TT has 58000 miles on the original clutch, and its been through 4 owners. Its smooth, but engaging quite high, so I think I'm on borrowed time as well. A good, smoooth driver can make a clutch last for a very long time. Much as I want the upgrade, I'm probably a least a couple of years away. Meantime... when will my turbo units start to give me trouble? I've heard around 75000 miles if properly cared for, and they'll need a rebuild. That will be an excellent opportunity for another upgrade.

Do some independent research on that kinematic clutch gizmo... it seems that Porsche dealers are quite ignorant of this part (as am I), and it can often be the culprit.
