Audi a6 c7 FL trailer hitch retrofit

hello !!

i try to retrofit trailer hitch, but unfortunately all labl are not up to date (using latest version of vcds), so i would like to know if there is something to recode in followin controllers :
- 17 (current coding : 138611003F550008000000), seems to be modifcation to make at octet 1 ?
- 5F (current coding : 017502010000000013110002000A00132F0006E5F17001009F)

regarding 6C, i don't know which octet is to modify (here my current coding : 0213000101010000000102000000)


thanks for your help !

Hello, thanks for you answer. Here the autoscan . I have already coded post of controllers based on what i have read in this forum or comparison with other cars.
I think nothing has to be modified in 17.
