Unforuntaly this BMW is a bit of a pain when it comes to fuses a majority have power even when the car is off.
Also since every make and model and trim is different BMW has sometimes changed which fuses #'s do what.
Anyway, you may want to try testing with the homelink or garage door opener fuse as that on my car was an ignition only power, i used that with an add a fuse for my valentine one. Every car is a little different unless its the same year and trim.
