Hi,
My audi A6 (03) starts giving me vibrations once I go over 60 mph. So it gets really annoying if I have to drive constantly over 60 mph on a highway as the steering wheel transfers that vibration to my head while I stay over 60. I bought it recently (pre-owned) from Audi dealer and taken it back to them to have this fixed. All they had to say that it was a shimming problem and that they have fixed it, but its still not. please advice. thanks.
