hi ive looked for alot of threads but none seem to have my exact problem unless im not understanding them properly, i have a a3 8p1 its 2004 1.9tdi now when i accelerate from standstill or floor it whilst moving between idle revs and 2500 rpm it ives a heavy judder vibrate then is fine even if i just pull away in first clutch only, it doesnt do this in reverse, occasionly very very rarely the clutch has started slipping a couple of hours into driving.... anyone got any ideas ? thanks
