in my 2003 a4 theres like a rattling noise that seems to be coming from the door handel or ower window buttons but it only comes when im driving on the highway because nyc roads suk but anyway did any1 ever experience this?

 

You probably need to have your tires balanced, since the car is shaking on the highway.

Or does it only do it when you hit bumps? Usually the Audi interior is fairly solid.
