Audi A4 dashboard backlighting - Andy_r
We have a '96 A4 estate in which the dash board lights and the centre console lights don't work. Its not the bulbs they have checked out OK. its prolly worth saying that all of the instruments work correctly.

I've checked the supply to the instrument cluster lighting which is OK. With lights on, the brightness of the odometer changes, so the potentiometer is OK. If I put a temporary feed onto the output of the instrument cluster to the centre console bulbs, they all work. So, the problem is in the cluster. Right?

OK, so does anyone have a wiring diagram for the pcb within the instrument cluster? or any other hints on what I might have missed?

Many thanks for your help,

Andy
