One thing is strange that why wouldn't it angle down when in reverse when it's already electric and it does it on the normal E92?
Not sure, but you can tell it dims because you can see the lining and I have seen mine dim before. I just mentioned it but make sure your switch for the mirror adjustment is set to the left for the right mirror to angle for reverse.
