So I got a left low beam error message on my console - went and bought some replacement H7 HIDs and installed them on both sides. My right one works as expected and my left one did not.

SO, leads me to believe the issue is not the bulb, it's the connector, wiring, or a fuse?

Anyone know if there is a fuse for each of the low beam headlights? Please say yes... I really don't want the dealership to dig through my wiring and charge me an arm and a leg to fix an issue that never should have happened in the first place.

As a side note - the MB dealership just changed my solenoid harness when I took it in for an oil change last week. Any idea if that could contribute?

Thoughts are appreciated. Thanks.

 

Okay so you put HIDs in the car.. do you have canbus error eliminators on it? Or is it coded to xenon=present? Does a new halogen bulb work?
