Re: 1989 Audi 90 Q thrust bearing. -Reply -Reply
In my case, I just had a dead unit. My starter failed twice without warning. In my
sister's 88 80q, i believe she had the same circumstances as yours with the grinding
noise that died when the clutch was depressed. Unfortunatly we never found out why, the
"high tech" german repair shop in Washington DC told her that her crankshaft was bad.
Luckily she knows a little about cars and got the hell out of there. The Mobil station
that finally did the work just replaced the starter and all was good. So, that is my own
long winded version of saying I'm not sure what it was.
