Hi all I have a 2007 S3, after hearing and reading that the racks wear out on 8p's I'm after some advice. I have a low speed knock from somewhere usually when changing going forwards to reverse and vice versa, the next symptom I'm not sure about at motorway speeds 70-80 in a straight line is fine no vibration but as soon as any steering wheel movement is applied it vibrates quite ferocious , I haven't had chance to go under and have a look but have shoved my hand under and carnt feel play in cv's, drop links, steering arms or the engine mounts, is this leading to the rack been shot?? Any help appreciated many thanks
