So to keep the flap open, it has to be done each time the car starts using the adapter and the iPhone app? No way to open it using Bimmerlink and then pulling the fuse to keep it open at all times with the adapter removed and not having to do the entire process each time?
Yes you can do that. Open with BimmerLink and pull the fuse. I didn't do that but I know it's possible.
Also if I do open it using the bimmerlink app, how do I test the difference in sound between open and close? Also is the difference only in the sport mode or comfort also? Lastly do I have to keep the car engine running while using bimmerlink or put the car in diagnostic mode?

So is it fuse 203, 223 or what fuse is it exactly on the 40i?

Damn $32 for the bimmerlink app? Wtf
I haven't pulled the fuse but I know you can do it that way, maybe someone that has pulled the fuse can jump in and mention the correct fuse.
Not sure if there was a difference in flap changing ability between sport and other modes, but you can hear and feel (hand in front of right side pipe) the difference when opening and closing the flap with the engine running, no need for diagnostic mode. Once the fuse is pulled it'll be open in all modes for sure.
$32 for the app and some for the adaptor, if you don't already have it. To be honest I bought the app to play with the valve and haven't used it since. Flap is still in auto.
There is a way to make it happen without bimmerlink, it's on the forum too somewhere, it's going to require you sitting in the trunk, ready to pull the fuse while someone is driving under circumstances that'll open the valve (sport mode over a certain speed and/or a certain RPM). Worth $32 to not have to do that....
