Hey Pete and MSB...
 

I took my car to the dealer this morning--the tech drove it and said something is definitely not right with the car regarding the vibration I get when starting with the wheels turned. They are also re-doing the road force balancing on the tires to try to address the high speed vibration. I'll keep you posted.

Thanks, I hope it is as easy the tires being re-balanced.
 

I had my tires re-balanced yet again yesterday and it got better, but the vibration is still there, taking it in next week.

Make sure the roadforce number is documented and given to you...
 

since it makes all the difference. If they are over 10, the car will vibrate for sure in my opinion. -Pete

Audi reps have flown out to my dealer and are test driving the car...the dealer has not been able to
 

figure out what is causing the vibration while turning. At least they appear to be serious about dealing with the problem.
