Sadly it seems like many people who have adaptive issues end up having to replace the whole shebang...which is just grotesquely expensive. Experiences like this make me very wary of ever touching my headlights, the potential cost (several k) is just not worth it. Like was said above, realoem is a good place to start. Are you still under warranty? If so yank the bms h8s and try to have the dealership take action. Sorry to hear about this....
