Just got warning light adaptive headlight malfunction and warning light low beam malfunction. One of the daylight running lights is out, not the outer rim light the actual light. Is that a bulb to replace or a bigger deal?

It could be the xenon bulb or the ballast. Easy thing to do is swap the good bulb to the bad side to test. If it doesn't light then try swapping the ballast.

Hey mine did the same. It was the module and not the bulb. The order was adaptive headlight malfunction then after startup for the 2nd time it was headlight bulb .
Dealer swapped bulb and did not work.

The drivers side on mine was replaced.
63-11-7-356-250 control unit xenon $517
labor $ 416 for 3.20 hours
You can did them used for $50-$100 and I think if you took off the splash guard , you could replace without taking the bumper off.
