I also have a sensor in the windscreen (just behind the rear view mirror) and dont have the automatic headlights or wipers. I quieried this sensor with the BMW service department and was told that its part of the automatic airconditioning unit (one of the anti fog sensors) that my m-sport has. Do you have this a/c unit aswell?

I have the intermittent and 2 speed full windscreen wiper options like you said you originally had. Maybe something happened when they removed your wipers? doesnt sound likely, but its all i can think of now. I did think that mine was using this sensor for windscreen wiper speeds, as they get slower when i stopped; but i just gather this is taken from the speed sensors instead (nice addition i must say)

Anyone else got any information on whether this sensor is used for anything light/wiper wise?

Thanks
