2005 A6 3.2. Humming sounds like it is coming from between the engine and radiator.

It is there when I turn it on, only slightly. Gets louder when I accelerate and when I turn (both left and right).

Any help would be greatly appreciated. The VW dealer said it would cost $150 to check it out, and I would prefer not to spend that if there's a chance I can fix it myself or by a friend that's a mechanic.

I just bought this car last August, and am new to Audi's. I'd like to get to know the car better, so I guess if I can do this myself, then it helps me!

 

start her up and stick your head under the hood and try to pinpoint the area of the noise
