I have a 2023 3.0 premium stock and saw an “Exhaust Flap” option in the Bimmercode app. I heard that setting it to “On/Open” doesn’t actually keep it open all the time, and people say pulling the fuse is the only way. Can anyone confirm if Bimmercode really keeps the flap open? Any other ways to do it without pulling the fuse?
Also, does keeping it open all the time cause any problems? There has to be a reason it’s closed at startup, right?
Yeah, it’s not a permanent change. You’d need to open Bimmercode and deactivate the flap every time you start the car. The only way to make sure it stays open is pulling the fuse.
