in our F31 we can schedule with a timer in the i drive menu the fan to start and get the heat out of the car before you start your trip. It is also possible to start this menu via an apple app.
Don't you have the feature in australia?
Okay, I never used it till now, as we picked up the car in october and due to autumn and winter seasion there was no need till now.
