Mine clearly doesn't dim when it's bright. Which part number have you got? Can you run it through bmwvin and check which mirror option you have or the part number for it?
I drove 470 miles the other day and pretty damn sure it wasn't dimming.
Im probably confusing things.. no dimming and dipping at the same time (but you've sorted out your dipping thing). Mirrors dimming in night conditions yes!
