Hello!  For the last few days I got a strange noice on my car. It can be heard better from inside of the car and the noice is all the time indifferent if I'm not driving the car. When I'm starting the engine the noise appeares and is stop when I'm switching the engine off. Could anyone help me? Thank you in advance!  20170926_210820_2.mp420170926_210820_2.mp4

Facelifted a6 c6 :)

On your video the aircon paned didnt not start up when you switched on the car , no temp displayed or any of the led in the buttons . Can regulate temperature and fan speed ? 

The noise soulds like an aircon on high speed

Hi! The air con works fine. I've turned off because I wanted to show that the sound is not coming from there. I attached another video with air con on and the noice is the same. Thank you!
