What do the heated steering wheel and adaptive headlights have in common? Answer: they are powered from the same relay on top of the fuse box - well in a 2006 Supercharged they are anyway.

I've had a problem where the heated steering wheel didn't work, the light never came on when the button was pressed. Multimeter revealed wires from steering wheel to fuse box were fine and there was no power at the fuse box. Similarly the adaptive headlights didn't move around and again their fuse had no power either. Changed the relay and all works as it should. Nice cheap fix!

It's the relayed shown here:
