It's in auto mode, auto recirc, AC on. Up to five people in the car. No fogging, no big temerature swings. Temp is usually 72 F (22 C) but ranges between 68 (20) and 76 (24) depending on how hot/cold I feel. I usually set the agressiveness to minimum but sometimes up to the middle. Temp control knob between the front vents is usually a full cold. Outside temps have ranged from mid-30s (1 to 3 C) to low 90s (32 to 35 C.) Humidity has generally been low outside, though there was one day with thick fog. No issues then either.
Double-check your settings (particularly auto recirc, which you didn't mention) but perhaps it needs to be checked by BMW.
That's how is should work. Same as in my F11 5-series.
For those with issues, just a point on setting the airflow intensity. Make sure you do it in auto mode, for the auto function to take proper control. Setting intensity in manual mode is a different function. (All in the user manual).
