I just got a 2006 R53 with checkmate pkg.
The original owner had additional fog lights installed and I can't figure out where to turn them on.
I've tried all the light switches but they don't come on.
ideas?
thanks

 

If they're aftermarket lights, your only option is to trace the wiring from the fog lights to see where it goes. Aftermarket light manufacturers like Hella give several wiring options in the supplied installation instructions. Could be the PO just wanted a cool look and the lights aren't actually hooked up.
