kinda worked for me...
I had the same problem on my '07 328i, and sure enough, fuse 57 was blown. So, I replaced it, and it worked fine....for a day. I dug a little harder and found the 20amp fuse replacement recommendation and did that. With the 20amp fuse, I get a loud clicking from my right rear actuator and it doesn't work. I changed back to the 15amp fuse, and it works fine.
I did not disconnect the battery at any point. What is the rationale behind that?
