Replacement of the xenon lamp Audi A6 C7 

To replace the D3S low beam/high beam lamp in the Audi A6C7 headlight, you will need a Torx T20 and a clip puller.
I decided to change it because one of the xenon lamps started flickering. Before you run to the store for a new D3S, it is better to swap them, since in A4 I had a problem with the ignition unit, and not with the lamp.
We remove the lid in the fender and unscrew the 2 screws T20
Turn the ignition unit counterclockwise by 45 degrees until it clicks, disconnect the connector and remove the xenon lamp.
