The problem is not indicated as "not present", confirming the problem occurs.
I ordered on EBAY the piece n°6 (actuator). The mechanical system is OK. I can open the flap and close it by hand.
Piece ref is n° 7511383
We will see ... Anyway BMW dealer would not have done more than me on this topic for now. The DIS recommend to change this actuator before anything else.

I believe you shouldn't be able to push open the flap when the car is off.
Does sound to me that something is broken inside the switch. Try this - take it off the actual intake - hold the switch in your hand and run the test and see if it turns correctly.
