Instrument & controls lighting gone awol
The instrument panel and control switch illumination has stopped working on my 09 D3 ...I have checked the fuse listings and can't find one that relates to the instrument lighting!? Tried twiddling the dimmer wheel but no joy there ...
If anyone can throw any light on the matter I would be grateful

Did you ever fix this. I think I may have a similar problem

well the headlight switch supplies the dimmed lighting, so could well be that if everything on the dash is off.
you could check the output on the back of the switch, with a voltmeter.
I'll tell you the pin number tomorrow

I checked the voltage on the leads that supply illumination to the clock and the start stop switch and I'm only getting 60mV. The voltage going into the BCU is at battery voltage
