This looks like it was made by the same company that made the factory repair manual for my old Audi, which is one of the better manuals I’ve used. Bookmarked.
Somewhat off-topic, I came across http://spaghetticoder.org/. It’s focused on E46/E39/E38 and newer cars, but their wiring diagrams and explanations of electronic systems are extremely helpful.
