I have a 99 b5 1.8t with 70k. I have had the car for about 8k. I have noticed recently that there is a rattle coming from the front when I go over rough roads or bumps. It sounds like it comes from the bottom of the front end. I think it could be subframe bolts. It is not really a clunk, but more of a low pitched rattle. If anyone could make any suggestions to help me pinpoint the problem, I would appreciate it.
