After having my driver's side "heated" mirror replaced for the fourth time during a recent servicing I was told that Audi had corrected the mirror problem by installing, in the mirror, a temperature sensor which turns the mirror heating element off when the glass temp. reaches a certain level. The new mirror seems to work well. At all temperatures, the mirror turns on when the car is started and then clicks off and doesn't turn itself on if the ambient outside temperature is above approx. 60 degrees or more. In the morning, when the temp. is lower, the mirror is in the "on mode" but actually it turns itself on and off like a heating element on a stove rather than staying on perpetually- you can actually hear it click on and off. I tried to get the service guys to fix the passenger mirror but they said it was heating fine - which I am sure it wil do until my warranty expires.

Anyone had their mirror melt? Mind did about a month ago. I was just pulling out of the driveway and noticed fairly significant white smoke flowing out of the mirror housing. I pulled back into the driveway, shut off the car and removed the mirror - the plastic backing had melted across the top 1/3 of the mirror - I've now got the new thermo-controlled and it seems to be working fine.
