Are you saying dimming doesn't work on the driver's side mirror? Because that would be opposite of how my car, and all the other MB's i've seen operate. On my car, and a few e-classes i've seen and driven, the driver's side mirror autodims, NOT the passenger side. At least this is what i've seen, and what i've heard other members report from Europe as well.

I have not seen a MB with dimming passenger side mirror.
