2015 cls 400 headlight fan noise
Was working in my garage and heard what sounded like a fan running on my cls 400. After long search if you put your ear to the headlights you can hear what sounds like a fan running in the headlight. The car is been off for hours but I still hear this fan running. I cant get it to stop and im afraid something will overheat and burn, or kill the battery............PLEASE HELP THIS IS DRIVING ME CRAZY!!!!!!!!!

You can have someone pull fault codes however, if headlamps are functioning fine with no fault codes most likely normal. See attached bulletin. BTW 218 should be posting here: https://mbworld.org/forums/cls-coupe-c218-157/
