I seem to be having a recurring issue with the adaptive headlights on my new C class. When I set off home from work in the evening, the adaptive main beam works fine. Then after a few miles, I get the "adaptive headlights camera obscured" warning (I cannot remember the exact wording). Then after ten minutes or so more it rectifies itself. I checked the cameras today and I am pretty sure that the camera housing is misting up on the inside. I think this is happening when I get into the car and switch on the heating. After a short drive the air inside the camera housing gets warm enough to condense against the windscreen (which is still relatively cold). After a few more miles, the windscreen itself has warmed up sufficiently that the misting clears itself. It didn't do this when the weather was warmer, which I think also lends weight to this theory. But it seems like a pretty basic and avoidable issue. Anyone else noticed a similar problem?
