05 A6 4.2 Engine Noise Humming/Buzzing
When i start my car theres a buzzing/ humming noise coming from the area near the end of the engine close to the throttle body. I only hear it when idle but when i accelerate either at a stand still or driving it goes away. I can hear it through the dash. And help is always welcome. Heres a link of what it sounds like.
