I've been playing around with NCS Expert after Mark showed me how to use it (thanks!) and so far I've managed to not brick my car
I did manage to change the remote bootlid operation though and I have no idea what I changed. Prior to coding the boot would open by remote with the doors locked but now it only opens when the rest of the car is unlocked. Anyone any ideas? The car is an E63 M6.

While on the subject of coding, does anyone know of a setting to force the car to park the wipers when the engine is shut off? The option seems to exist for the E9x but I can't find an equivalent for the E6x.
