Hi Pany,
When you day you were feeling a lot of feedback through the pedals was it fairly extreme? At about 80mph/3k revs i can feel a small vibration through the whole car and if i put some very light pressure on the clutch it feels quite 'lumpy', i know what you're thinking, could be the wheels but i had them all rebalanced and should be fine.
Having never put a little pressure on the clutch whilst moving, it may be completely normal to feel a little lumpy, so not really sure. As for sounding like a tractor i have always though the GTi sounds a bit rough and mine doesnt seem to have changed,
Did yours feel lumpy when actually driving too? and how long was it from noticing the symptoms until it went Bang?
Thanks,
Ri
