Code 2F11: radiator blind, top

[makros]

I have some issue with cooling blinds on my car (E61 N53B25)
Have someone had similiar issue?
I already did some research and i found 2 solutions:
1. repair this blind(s)
2. disassemble blinds and code them off from FA.

Since I'm few days before my vacation I have to do this repair quickly, so I want to do the 2nd option, so code them off from FA, but I have no idea how to do it.
Do someone know how to code them off from FA, and maybe there is some tutorial how to disassmble this blinds?
