Bob, the Vanagon has no type of fault code memory what so ever.  No OBD
II, no blink codes, nada.  However you can usually troubleshoot your van
with an ohm meter and the Bentley manual in about 30 minutes and find
99% of all problems that way easily.  There is a section in the Bentley
that gives you the tests to do at the ECU plug (under the rear seat) and
you just go through these tests one at a time, check your results
against what the book says and BINGO you found the problem.  People
think I am a miracle worker because I do this and fix their vans.
However if they just took a few minutes and did the tests according to
the book they could do the same thing (don't tell anyone:).

The digitool is nice because it allows you to do these tests in real
time but you still have to do the tests from the book.

Hope this helps,
Ken Wilford
