Another "feature" in the vent system is that sometimes
there's no air coming from the middle ventilation (the
one above the radio). I can fix it by pretending that
the car is a PC and turn off the ignition and start it
again. Voila, the vent works! Any ideas?

========================================

Sounds symptomatic of the early IHKR (IKHR?) control module problems.  There
is a BMW issues Technical Service Bulletin on the IHKR problems, but no
recall.  Other symptoms are no heat output from the vents (footwell) during
the winter months, but when you restart the ignition, you then get heat
output.  If the IHKR is faulty, fixing it requires some re-programming by
the dealer.  Brett Anderson may have more info on this.
