Hi, I've recently bought a 2001 S3 with 60k on the clock... everything was great for a week until I snapped a front spring. Ever since I've had this replaced its been making a very annoying intermittent knocking noise. My mechanic checked everything and found slight play in a track rod arm so we replaced this but the noise is still there. One possible thing I thought it could be is the top mount, the broken spring slightly bent the cup and this was straightened back out out in a bearing press. My mechanic says its all fine though. Could just be a coincidence that the noise appeared after the new spring was fitted. Noise is mostly at slower speeds and is coming from somewhere up front. It might be my imagination but it seems to get quieter after the cars been driven for a bit. Anybody any ideas what it might be?
