I've had this issue for awhile now. Mostly on moist or rainy days I get the occasional "check low beam" message, reported to dealer and all they did was change one headlight assembly. Didn't solve a thing, and now that I'm out of warranty I have no idea what I can do. May I note I have a weird problem that my passenger headlight points far to the right as well (adaptive headlights malfunction?).

Just today, my driver side xenon bulb is burning out, anyone have the DIY for changing the bulb?
