These are the instructions sent to dealers telling them how to order the enumerated "vehicle specific parts." One of these "departments" is at Daimler (MB) and the others are at Chrysler, now FCA. If you own a fleet of Sprinters for a delivery service, for instance, and a driver loses the key, this is what a dealer has to go through to get a new one. If it's an MB version, the MB dealer sends the order to their guy, in Stuttgart, I think. If it's a Dodge version, Chrysler dealers send it to the Chrysler department, at FCA, but they have to have it coded with the software that is proprietary to MB, using the codes that Chrysler (or FCA) owns.

An Aside: I would think a strong case could be made that I, as the owner of my Crossfire, which I bought from Chrysler, own the code, at least equally. It's my car, I paid for it, I deserve to own = at least co-equally - the codes required to operate it. Probably I should be, at least, guaranteed access to the MB hardware and software to help you guys, so I'm trying to do what I can with re as well, but you can see where all this goes ... legal fees. Sorry, I can't put up the dough for a law suit, but I'll do what I can with what I have. This has already taken a helluva lot of time.
