You are going to change the coding in a few modules. I believe these are 01 Engine, 07 MMI (This doesn't appear in your scan??), 16 Steering Wheel, 17 Instruments. If you pull the fuse on the Radar you can remove 13-ACC from the gateway installation list.

As for the actual coding values to enter, you are going to have to to your home work. Check the Ross Tech wiki for the 4F and here

Currently the ACC radar is disabled in my A8 and regular CC works fine.
