Well, I placed a piece of tape with a small hole cut in it across the sensor on the back of my mirror to see if it improves the dimming feature. My thought was that there must be comparison between the ambient light (rear of mirror) with the light from the front mirror side.

To be honest I can't tell very much difference. My next test is to completely cover the rear sensor to see if the mirrors dim more quickly.

I can't believe I have to use duct tape on a (near) $70,000 car.
