Audi A4 S-reg 1.9tdi...
Can someone explain why my windscreen wipers stop working? The indicators also stop working although hazard lights remain active. I have noticed that when this happens, the following items also fail, Fog lights, rear window heater, indicators windscreen wipers and the air con/heater. Its an intermittent fault and its not clear which item is to blame. I suspect the heater and logic controls for it, but is there anyway all these functions could be linked in some way?
The main dealer has replaced the ignition switch...it did not cure the fault.
Any ideas welcome, thanks
