Help with Lights ??

[SHA3UN]

Hi,
I have a 2008 A3 2.0 TDI & i am having issues with the lights not working.
The drivers side Side & Fog don't work, Rear Passenger & Right indicators only work when i have the side lights on ??
Anyone able to help with this please ?
I have had the car in an Auto Electrician's & he said he can't find the fault !!!

It is a computer controlled system, the so called J519 central electrics unit and this is linked to the rest of the cars systems, such as the central convenience system, by a digital CAN BUS, the sort of thing I imagine your sparky has nightmares about. Firstly you need to have a global scan done with a diagnostic computer dedicated to VAG vehicles.

Crasher do you know where the J519 Central Electronics Unit is on an A3 ?
Also would replacing the unit fix this issue or can the faults be deleted ?
