What little I know of OBD (via the Jetta engine I installed in my '81)
is that it's programmed into the ECU.


I would think it would be next to impossible to somehow upgrade the
WBX ECU to incorporate this. But what do I know??


<grin>


OBD sure is handy, but from what I"ve read, isn't the "Bee all and end
all". i.e. under Motronic 2.9 OBD1, (going from memory on the correct
phrase) if there's a "short to ground" shown for the cam position
sensor, that short could be at the sensor on the dizzy or elsewhere.
Say in a wire(s) in the wiring harness. Yes it can point you to a
component, but it won't tell you everything. That said, I think OBD is
pretty useful.
