I just purchased a 2003 BMW 525I and in the middle of one of the defroster ducts, on top of the dashboard, there is a black sensor of some sort wired into the dash but, the sensor itself is loose and can be moved about 3 inches to either side.
Does anyone know what this is? I can't find a reference in the manual or online.
I am not sure how it works on the BMW system, but the unit that was on my GMH Berlina detected bright sunlight and automatically bumped the climate controllled fan speed up one setting, and dropped it back in lower light levels. I expect that BMW are doing some thing similar, although I would have thought that it would be retained somehow.
