Hi, I have a strange problem with my S4 cab that only appears when the weather is wet/damp. When turning hard lock to the right I get a cracking noise coming from the NSF wheel. The problem does not occur when it is dry. Audi have had it in on numerous ocassions and have failed to rectify the problem, I've had the suspension arms replaced and also the bushes. My feelings are that something is swelling due to the moisture and causing the noise. Has anyone else experienced these symptoms or have any thoughts on what it could be?? Any thoughts would be greatly appreciated.
