Veeery interesting... (Laugh In??)

All of the Jetta types were using Digifant. Note if you drop the first three
digits (vehicle type identifier?), the remainder is the same (ETKA calls
this the 'base part number').

Looking at the diagrams etc. I am going to assume this for my use (yours too
if you agree)

"Similar vintage Digifant systems appear to share the same components. Such
as mass air flow sensors, idle control valves, possibly more."

I'm going to check a few more parts to confirm this. The real test of course
would be to plug one in a WBX and find out :-)
