thanks to everyone who replied to my earlier threads! much appreciated. After lots of head scratching problem turned out to be the dual mass flywheel collapsed, destroying the clutch at the same time.
I have found a clutch/flywheel kit on ebay for £150: Audi A3 TT 1.8 T 1.9 TDi Flywheel, Clutch, Cylinder 96- | eBayas anyone got any experience of these, are they worth getting or should i just fork out for a VAG one?
Also my mechanic is concerned that there are many different sizes of clutch for these? is this right? i thought it was a simple matter of checking my registration number against the database?
