Headlight bulb issues

[Thea]

Hi.

 

I'm new to the forum but wondering if anyone can shed some light on a problem. I have an is220d have had it for two years and no major issues until now. The headlight bulb went on the passenger side which was changed in the garage but it still isn't working. There seems to be no voltage going to the bulb unit and I'm wondering if it could be a fuse or relay issue?? Any help gratefully appreciated. 🤞😊

Hi

I had this problem on my 430 - I purchased new bulbs bu that mae no difference - turned out to be the ballast - IIRS your car Xenons - could this be the ballast?

On the 430 the ballast is secured to the under side of the headlight

hope this helps
