by the german description this sets dimming of the door mirrors to be set by the inside mirror by the following formula

Door Mirror =(Interior mirror/32)*Factor

my factor is werte = 20 which would be 32 in hex, so the outside would be set to the same as the inside. Since we are talking about dimming, I think if you want the outside to be darker you would increase the multiplier factor.

haven't tried it, but it could be a starting point.
