Hi guys,

I'm the new owner of a 2009 A4 Avant, certified by the dealer...So I thought.

After 2 days, I brought it back for changing the mechatronic, and for a vibration problem. They balanced the tires one time. The vibration was still there. I brought it back a second time and they tell me it's ok...Guess what, it's not.

Anyone got an idea of what could be the problem...?
The steering wheel shakes at 108 km/h...

Thanks !
M
