Put the adaptive headlights back on unless they burned out and he replaced with LED ones to save money. Many aftermarket headlights will throw codes especially because adaptive headlights follow the steering input. They turn when you turn the steering wheel. Personally, not a big fan of them. When i was driving on dark, narrow, windy european roads, they helped a little bit but overall just one more expensive thing to break. Most people drive 1Ms in daytime anyway. you might be able to code out the error by telling the ECU that you don't have adaptive headlights but that would take someone with some coding experience.
