Hi, I have a 2002 Audi A4 bought new and it has low mileage but I've a problem with the indicators, emergency lights. They go off for no reason,open a door and they go off,lock the car and they go off. I have to switch the lights on and off again to turn them off and it's all luck that they won't come on again...anyone have any ideas on what it could be down to? When I'm driving I have to leave my parks on so they won't come on😭
