Vibration, humming..
Hey all, i just noticed that when at a full stop i sense a small vibration and humming coming from the engine bay. It almost relates to when you are braking when the calipers won't grip the rotor, when this is done you feel some vibration. This just started a few days ago, never noticed it before, was wondering if this happens to anyone else. I was thinking it could be the motor mounts. Thanks again..

Re: What year, engine, and how many miles on car?
It's a 2001 4.2 A6 with about 63,400 miles on it. I brought it to the dealer due to a ticking noise, which they couldn't find a problem for so they put some fuel injection cleaner, and soon after this problem developed. I usually let the car warm up for about 5-6 minutes before driven, if that has anything to do with it.

Take the belly pan off and have a look. If you see the black-purplish fluid at the base of the mount, their shot.
As far as the humming, it could be anything(waterpump, bearing, trans).
