after 2-3 days i have starting trouble. how can i fix the problem?
have orginal rns navigation. allroad c5 2003 model. i recently put in a pioneer 2din player, but i had the same problem before i put the new player in the car.
In my case: I had a bad door microswitch. The doors all locked just fine, but the microswitch did NOT inform the ECU that door is locked. So the ECU (or othe rmodule?) did NOT go into 'hibernation' or sleep mode, continuing to draw high.

I fixed the door switch and the draw disappeared.

Ok.
But how did you know that one microswitch was bad? See it on a vagcom? I think the switch 2 the backdoor is bad, had a problem with it knowing the back was closed
