The light sensor on my 2003 Audi A8, after failing intermittently, has now stopped working completely. At the same time - and I am guessing the two things are connected - the automatically dipping drivers door mirror is now permanently dipped dark which means at night you can't see anything in it. (It beats me though, why the default setting for the door mirror wouldn't be 'light' rather than 'dark').
Oddly enough, this doesn't seem to effect the auto-dipping rear view mirror which doesn't work but as luck would have it has defaulted to 'light'.
When I select the 'auto' headlights position a message appears on the dashboard saying that the 'light sensor is faulty'. Where is this sensor? Does it control the rear view mirror and the door mirror dipping function?
Thanks,
Mark
