2021 M440i exhaust flap fuse.
Anyone know the fuse box location and fuse number for exhaust flap on 2021 M440i Drive? Wanting to permanently open valve without bimmerlink or unplugging underneath vehicle. Any help would be much appreciated!!

Open the rear fuse panel in the trunk and look on the far left side for a 7.5a fuse that’s directly above a 5a fuse. Make sure your car is in Sport with the valve open, then pull that 7.5a fuse and you’ll be good to go.

My fuse panel is not exposed. I assume it’s located behind the side panel in the trunk above the right rear muffler, where the only flap is located? Again, thank you.

Found it and that did the trick. Just fyi, you can hit the start/stop button 3 times (don’t start) and then press the gas to the floor, let off. Puts car in diagnostics mode and opens the flap. Pulled the fuse and now flap stays open at ALL times while car is running (Eco, comfort, sport, sport plus). When you turn the car off, the flap closes but opens immediately upon starting in any mode. Mucho thanko.
