Actually, there's no difference which gateway module you will use. It serves only for communication between K-Can, Pt-Can and D-Can or K-line. Using KGM instead of JBBEII gives you nothing, because both doing exactly the same thing. It doesn't matter that your car is E63, JBBEII can be used to bench diagnose, flash and code any module from your car. If you still want to use KGM, it is correct that it has D-Can pins on 16 and 17, but it also has K-line pin that can be used for communication. It is like that, because BMWs after 03/2007 use CAN in diagnostic socket, and ones before 03/2007 use K-Line for diagnostics, despite all modules in car use Can to communicate with each other. I don't know why there's no D-Can on KGM schematics and pinouts, because as I said above, cars after 03/2007 use it.
