I think my old e92 used to turn the heater on automatically if I put my windows down at night. Or at least turn the air on, regardless of what temp I had it set at. I remember repeatedly turning it off one night only to look down and see it on. I sold the car soon after so I didn't have them look at it. The heater also used to randomly cut out for about half a second when on full blast. I know this isn't x5/x6 relevant but maybe they just have weird ventilation programming.
