I am really confused. My headlights have been intermittently failing to ignite so I took the car in. They said a rubber piece was missing but it is now fixed. Anyway, now the passenger side light is yellow, like any other car. Is it possible that they replaced it with a bulb of the wrong temperature or even more F'd up...a standard incandescent light? The service ticket said the headlight assembly was replaced. The adaptive feature that moves the light right and left on curves still works.
Thanks, Steve

 

Steve - just for future reference, the moving lights are called AFS

but as far as the color change, if you took it to the dealer I can almost guarantee you they replaced it with a OEM bulb (4300K)
