I have a 2017 c300 coupe. No major issues with it but a few days ago the front right side market light I believe is what it’s called wouldn’t turn off. I tried playing with the parking lights but that didn’t make a difference and my dealership wanted me to pay $180 to diagnose the issue. Has anyone had this happen to them? It’s the front right yellow light on the side. Not sure what to do.
