Hi guys, I'm new to the forum and also the proud new owner of an '00 S4. My problem is this however; my left front suspension has developed a knocking dull rattling sound when driving bumpy or rough roads. It doesn't seem to be a shock problem because sharps bumps are absorbed as usual and there is no noise under compression. If I could pick up the car and shake it, that would probably cause the noise... bad bushing perhaps? I hope someone out there can help.
