Hey all, I was driving my W212 back yesterday and all of a sudden my right (drivers) side projector started flickering on and off suddenly. This is a new issue and I can't seem to workout what is going on. I attached a video of it here. Any advice on what might be going on? Thanks

If you have bi-Xenon, then it's likely a control unit. Had the same thing happen in my W211 just a month or so ago. Tried replacing the bulb first to no avail.

Most likely the ballast failing

On facelift W211s the ballast and control unit are actually integrated, not sure about the w212. They are separate on pre-facelift W211s
