I had to order my dummy plug from the dealership and it's coming from Germany so I'm two weeks out from doing this.

Mine definitely didn't start with the flaps open as its so much louder now haha.
The flaps stay open when you turn the car off, so easiest way would be to start the car, put it into sport, then after 30 seconds or so, press the accelerator slightly and you will hear the flaps open. Turn the car off, then fit the plug before restarting
