Is the VW digifant/Digijet system OBD compatible?  If so, where is the
connector to interface the OBD computer to the vehicle computer?  Where are
the trouble codes listed?

Without OBD compatibility, I do not believe you can look at the OBD
"traffic"

Unless you are speaking of a generic on-board diagnosis capability, and not
referring to the On-Board Diagnosis protocols which have been standardized
across makes and models...this will cause some confusion in the automotive
diagnostic world; be careful when referring to OBD to avoid confusion.
