Mine only does that when its raining or damp outside and it did the same thing in my old 5-series and the current 5-series. If that is what you are referring to, it is a normal operation of the system.

I does this more often when it's 85+ degrees. It just started doing this recently before it was operating fine. if it was anything but a BMW I would guess it's a vacuum hose leak that causes the vents to change. But then again with a BMW if it's a vacuum leak you would expect a CEL. Car is an only has 80k miles..
