slipping clutch symptoms

[adw555]

Just wondering what the symptoms are for a slipping clutch on my 2 yr old GTI (27k) ....I've noticed particularly going up from 3rd->4th->5th the revs dont seem or sound like they are dropping as much as they did...it sounds more eager...maybe the engine is now loosing up more...just wondering what I should look for

adw555,

A sure sign of clutch slip is to put the car in 6th at 35-40mph and push the throttle to the floor. If you get a surge of revs that isn't in line with the increase in speed then the clutch is on its last legs. If the car simply gradually increases its speed along with the revs then you should be ok.

That actually sounds like a problem with the engine management!  You seem to be stating that the revs are "holding on" between gearchanges, rather than dropping much quicker.

Hurdy is correct with his simple test on clutch slip.  Another test, and you'll need to find a quiet flat straight road, is to do as Hurdy suggested, but whilst keeping the accelerator to the boards, GENTALLY press the clutch pedal.  If the engine revs rise frantically the moment you merely sneeze at the clutch pedal, then your clutch is shagged.  If you need to press the clutch pedal roughly half way to the floor, then your clutch is fine!
