I have an 03 audi a4 1.8t that is having problems. Now when I turn my car on, the headlights and all the other lights inside the car come on. It doesnt do this always but sometimes it does. If i turn the switch for the lights on like it should be then off, the lights turn off. Also when I turn on my fog lights, they sometimes turn off and on while i drive. What is wrong with my car? Also, my radio doesnt get a signal for radio stations, could this possibly be related to my headlight issue? Thanks
