Re: Dash Noise

My A4Q does the same thing...the small high pitch noise.
When I go to freeway, I will turn my radio loudly.
Next time I will turn it off and listen carefully the noise problem.

BUT, when I just start or stop my car, I can definitely hear the high 
pitch noise. not loud, but enough to make me crazy.

I found out that the noise getting louder when I step on the brake.

Any A4Q owners have the same problem?
