Could anyone help please? I am concerned about my Audi A4 S-line 3.2 V6 FSI Quattro. I have recently noticed that it is not as tight as it felt when I bought it a year ago. It feels a bit shaky going from say 50mph up, I thought it was the wheels not balanced properly, but I had the wheels balanced and it's not them. The track rod ends also look like they are in good condition so I don't know what it could be? I have also notice recently that from time to time the car feels like it is stuttering. It usually happens when I have taken my foot off the throttle or am sitting at low revs. The car doesn't loose any power but it just doesn't feel right. I have also had 3 occasions that I have gone over a large speed bump and god car has knocked itself completely off, could it be a loose connection or something more sinister? Any help would be greatly appreciated!!
