I have factory tints and dimming rvm + folding/dipping wing mirrors. I also had this on my A6 C7 and my previous A4 B8 Avant. All have responded the same, which is quite sporadic in when it chooses to dip the rvm and mirrors. As Chris has said people using high beam still definitely trigger it, even with tints, but the system will also work with lights on normal dipped beam but it seems to be more hit and miss.

I understood (but could be wrong) that if you have factory tints the light sensors are adjusted to compensate for the tint.. I've never had a car without tints so I'm not sure how effective the system is without.
