Hey out there.

I have a 2000TT Quattro with 50K miles, just bought it last summer. There is an intermiitent low pitch squeek/rubbing sound that seems to be coming from the chassis (or maybe the Quattro mechanics?) It is not speed related, but may be road surface related I cannot figure this out, and before I take it to the Audi Dealer and sound like a fool, it would be good to hear of any possible sources. Anyone have any ideas?

Thanks!
