Moin, this morning I had repeated problems with foggy windows in the car. It was cool, so 4° and just wet outside. The windows were still all free inside when I entered. Only when I then turned on the engine, all the windows started within seconds. It then took several minutes until the climate got away the humidity. -Pollen filter is almost new -Climate had the summer over very good cooling performance -It does not evaporate from the ventilation -Car is dry inside(carcase, trunk etc.) Do you have any idea? Car is a 2011 GH 2.0 gasoline automatic, 70tkm.
