sucks, i wish i came here before i ordered the exhaust dummy plug. You can add me to the list of 'i noticed the f36 def has a different logic for the flap'.
I wonder why....
PS. the bit about backpressure is hogwash. wayyyy too far downstream to impact backpressure lol. As mentioned it is for cat efficiency, but also because cold starts on this car are quite a bit "loud" (if you have a DP, you know...) for the non-car-fanatic BMW drivers.
