I have done this with 2 different G11, perhaps with G30/31 it´s the same.
I can´t describe it step by step, sorry, it would took me too much time, but perhaps it will help a little bit.
First you have to downgrade the KAFAS4 to KAFAS3 by manipulating the TAL by hand. Both have the same HW. As data use for example psdz 59.4 in Esys. In KAFAS3, there will be no FSCs needed and will work without
Then code KAFAS, HU and KOMBI with 5AS and delete by hand all not needed functions like lane departure warning, rear collision warning and so on...
