I have an 01 A6 2.7 and last night when turning on my headlights the radio tunred off. it is a symphony2 I believe.
I tried out different scenarios and found out that when I start the car with the headlights on the radio stays on but as soon as I press the brake the radio shuts off again.
The lights that would be iluminated when driving with the radio off are on it just does not respond to my attempt of turning it on.
Very strange ...
I would love some expert advice
thanks...
