Hi all
Initially the Front fog or DRL stopped working the the indicator and then the headlight all on n/s front, checked bulbs and fuses all ok, removed front bumper and checked wiring loom al seems fine, looks like the culprit might be the power supply control unit but I have no idea where it is anybody know?
Many thanks

If you go up a level there are loads of other diagrams / layouts. You haven't stated what year /model your Q5 is though.
