Another idea, is there a German equivalent for an electronic component that
starts with B?

Since the 'B' is ambiguous, is it possible a bridge (normally 'BR")?
Again, the schematic should answer any questions.

it possible to add an OBD interface to the Vanagon :-O. ... of course, it
would probably be more effective to simply add a Subaru flat-four with its
proven computer control system.

case. I would guess that B202 is a inductor or coil. L usually stands for
coil on U. S. schematics, but maybe VW uses B for the B field associated
with a coil.
