Recently my wifes 135 blew an orange corner bulb on the passanger side. I swapped it out and it worked fine. After firing the car back up and driving it around, the adaptive headlight warning came on. Now it wont light up when turing the wheel left/right.

Everything else seems to work;
Low/High beams
Auto Level (up/down) on start-up
Angel Eyes, etc.

Is there a way to troubleshoot what the failure point is? I'd drop it off at the dealership but the damn car is 2 months out of warranty. Of course. If I can figure out what's not working, I can certainly replace it myself.
