I guess my point is, 37 degrees is pretty surprisingly high to just decide it's going to not work, as it basically means that the system won't work for close to 50% of the year around here. Maybe it's the difference between a Munich dwellers idea of cold weather (which I don't think get's that cold), and places that do like Chicago.

My manual specifically states it shuts off at 3ºC which is about 37ºF. I don't know why yours doesn't.
I guess they do this because BMW has a lot of experience monitoring elctrical loads of their cars. You know rear window defoggers, seat heaters and other things come into play at those temps. Not to mention that batteries develop a lot less electrical power as they get colder.
