BMW g31 ; 2018 year ; ACC retrofited - Coding needed ?

[Sschraube1]

Hello together,

i retrofited an acc sensor and a new steering wheel ; with ista it tells that my wiring is ok and i habe communication with acc / power is there too.
i wanted to integrate acc with ista , but i doesnt work.


Do i have to code first the vo for acc or i only have to integrate the acc on ista ?
If i have to code, which vo is that ? and which modules ? SAS/ instrument cluster ?


Do i need to code headunit ? (I have carplay)


sorry for so much questions   ; i code so rare, also only my car so i dont know everything



and thanks in advance
