Humming sound...
Hey all, need some help...Have a humming sound in my '06 A8L. Seems to start after car gets warm and doesnt go away. Appears to come from under the cowl. After investing a couple thousand dollars in the suspenion recently, I'm hoping this is as simple as a small vacuum leak or something...Fingers crossed.
Thanks,
Greg

Also, if it helps, the humming does gets louder on some occasions(when turning the wheels). Made me think of power steering pump, but the location of the sound made me think that wasn't possible.
