OBD2 / OBDII refers to generic powertrain diagnostics (engine, emissions, etc) for all vehicles. Plenty of dongles for that. But I mean something that emulates the tool a dealership would have for specific makes of vehicle, which goes far beyond just the engine, extending into every module, possibly like what you found. Although usually it would be for a family of makes, not just a family of models.

For VW/Audi/Skoda/Seat the popular ones are VCDS and OBDeleven (the name of the latter being a play on OBDII, confusingly, being that I am trying to differentiate actual OBDII... ugh).

OBD, yes, of course. I spent a lot of time with ODBC years ago, and I can’t seem to keep the letters straight in my head.
