Ah crap, I totally misread the whole thing.
I now understand you had an aftermarket auto-headlamp system installed. Man, sorry about that, I thought I read aftermarket bulbs. "Sheeesh" to me, I guess. When you get into this sort of thing (aftermarket components), I can't help much on how it operates or anything. "Too new" sounds like a good excuse to me, too. As long as the auto system can be defeated, if the installer says he can wire up the fogs to the headlights, "why not" if that's what you want. I guess I was thinking in terms of the car having auto headlamps from the factory, because most new MB's do. Your 210 E class doesn't but the next generation 211 chassis will.
