hello wonder if i can get some advice from somebody. was driving home from work today and stoped at lights on a hill. they changed to green and i went to drive....but all i got was a big clunk and a lot of revs. needlesss to say i had to get towed home. i think i might be the driveshaft or clutch. more inclined to the drive shaft as there was a big clunk and no warning that the clutch was on its way out. and help or advice would be greayly appreciated. its a mk4 sri 1.8 (2001 model) many thanks in advance!
