Did this on my previous F82 and while that was fun, the cold start of the F82 with the flaps open all the time was obnoxious. And this sounds better.
Ready for it.....
Pull fuse F203!
1) Turn car on, put in sport. *Ensure the flaps are open
2) Go into trunk, pull fuse F203 (while car is still on)
3) Verify flaps are still open
4) Close trunk
5) Enjoy
