Hi,
First time posting, sorry in advance if wrong forum.
I have M550i 2018 with 2VF option, Adaptive M Suspension. I want to retrofit / change / upgrade it to 2VW, Adaptive M Suspension Professional.
Got a donor, everything is fine etc., but right now I am confused.

As far as I understand, I need a part number 12. But there is literally zero information available about it.
Maybe someone had an experience and could help me with this? Thank you in advance.
