Hi, I have a new model '04 Audi A6. I bought it just 5 months ago and it does not feel as comfortable to drive as i would expect. When you go over a pot-hole or even an uneven surface on the road it feels as though my fillings are going to fall out. My wife drives an '02 A4 and that feels a hell of a lot smoother to drive. A friend of mine suggested replacing the tyres and getting the wheels balanced but its a bit expensive if it may not make a difference. There is plenty of "meat" on the current tyres so they should be okay. Is there a way to test the suspension? Any advise appreciated.
