The 2012 includes the VM diesel but must be the European or Oz spec.
Note: What follows is speculation on my part.
Have seen this sort of thing before when an inside organization is chartered to create "something" out of an existing (usually mainframe) system. An Exec looks at bids for such a project and decided that since they have all of these IT people, they can probably do it in their free time.
Of course mainframe people don't want to mess with pc stuff so they give it to the guy who mutters to himself while reading Byte. Given the style of the XML and SVG structures, I suspect the main tool used was Adobe Illustrator 15.1.0 but the XML is 1.0 which is earlier.
So "someone" decided that the easiest way to do this was to extract relevant bits of the online service manual system onto a CD.
The dealer system appears to be a multi-year, multi-element program, part of which is in a meta-index which can provide SEARCH and a vector graphics engine that supports zoom and move.
What was provided was something that could only use a specific browser (IE) that is only available in Windows. A set of search results were each transformed into HTML, XML, SVG, JPG and GIF constructs. Naming uses an encoded GUID (Globally Unique Identifier) which was probably machine generated. Certain things were left out such as the complete wiring diagram, index, and search (I had to create my own index program for fault codes).
So we have "something" that is only usable with very specific operating systems (no MAC or iOS or Android) and just one browser IE 10 (can use with earlier versions with the Adobe driver package last updated in 2009).
For some reason the whole system reminds me of the Helena Rubinstein R-390A.
