The one on my M3 doesn't work. BMW simply say "computer says no". The
one on my E38 does work but does it differently. If I have the lights
on but it's not dark then I can't see much out of it, regardless of
Thanks or the replies. I think Luc's idea sounds worth a try. Thinking
about it, I assume the that it works ( darkens ) when the sensor on the
mirror glass gets more light than the sensor on the windscreen side.
Covering the sensor on the glass could very well work - I'll let you know.
