Volks,

I was doing some research in the archives in relation to a thread on the
WetWesties list and came across some rather recent posts in which a few
people stated the the AFM related Vanagon Syndrome only occurred in
Digifant Fuel Injection System.

The Syndrome effects both Digijets and Digifants.

The following information was found in the archives of the Vanagon.com
list or on its web site over 5 years ago.

"The first VW Service Bulletin, # 92-01, 2/29/92, applied only to
Digifant, but was soon superseded by Service Bulletin 92-02, issued
4/30/92, to include all Digijet AND Digifant models. No aircools were
involved, as they had the non-digital (analog) L-Jetronic fuel injection
system."

After failing to find the actual service bulletins on my computer, I did
some further searching on the Internet, I found this at the Syncro.org site:

"Technical Bulletin Group: 24 Number: 92-02
Date: April 30, 1992
Subject: Vanagon Driveability Complaints
Model(s): All Water Cooled Engine Vanagons

SUPERCEDES TECHNICAL BULLETIN 24-92-01 (February 29, 1992)

CONDITION: After driving for an extended period of time at a constant
speed, the vehicle may, on occasion, experience a deterioration of
performance which may be accompanied by a hesitation or surging. In many
cases, after turning off the engine and subsequent re-start or without
having taken any action, the symptoms disappear."

The whole bulletin and the first one, along with many others, are also
there.

The problem comes from erratic signals sent from the AFM to the ECU and
the AFM's of the two systems are virtually identical in basic structure.

Hope this provides some clarity if anyone thought it was just the Digifant.
