Okay, I have an '04 a6 s line and for the past year and a half my steering wheel has been shaky. Sometimes it's hardly noticeable and sometimes it's so dramatic that I can take my hand off and it looks like its been possessed ( It will shake about an inch in either direction back and forth). I have taken it to Audi and some other shops and no one can figure it out. I've had tie rods, boots, cv joints, and all 4 tires replaced. I have had everything looked at from my steering column to my tires. I have also had my rims fixed (twice to be sure) and all tires are properly balanced. I have also had my alignment done as well as a road force balance. PLEASE HELP ME! THIS SHAKING IS DRIVING ME OUT OF MY MIND! I just want this issue fixed!
