Last week, my a4 1.9 tdi esp and abs warning light went on, on at a time. In between, the wipers, the turning lights, windows and buttons on the key stop working. I stopped the car and took the key off and both radio and the interior light didn't went off as they should.
I checked all the fuses and all are ok, so I disconnected the batery. The lights went off and everything was working again, until the next day. After a few miles, the problems started again. A disconected the batery again, but result wasn't as good as the first time.
Can you help me!
