05 Auto dip mirror - Can you make it switchable ? - Walton2
The ST TDCi has an auto dimming mirror which I find OK but the better half doesn't as she finds it hard to judge distances when it dims. I've leant that if you hold your finger over the sensor on start up it seems to disable the auto-dimming, but I/she usually forget until somebody dazzles with main beam or poorly set lights. Is there anyway you can switch it in and out of operation on the move? Nothing in the handbook that I can find.

I use a 2001 Ghia with auto dim mirror which I find very good but mine has a switch on the front to disable the function.Perhaps this earlier type may fit?

Audi have a switch by the sensor, but a piece of insulation tape over the sensor will do the same job.

My '02 Ghia X has an auto dim mirror which is very good though has an off/auto switch, havent noticed that the later ones dont have this switch.
