My Son has an Audi A3 Sport 2003 Registration and for no apparent reason the Hazard Warning Lights came on and the doors unlocked, this happened several times I had the local garage have a look and they said it was the Radio that was causing the problem, they disconnected the radio and all seems well, can you advise on this problem

 

well if disconnecting the radio solved the problem then it would have to be a problem with the unit itself or bad wiring to the unit.
