"Vanagon Syndrome" Air Flow Meter Harness

We are happy to announce a high-quality harness that replicates the original expensive VW harness that was created to solve the dreaded "Vanagon Syndrome" problem that was experienced with Bosch Digifant (86-91) systems (see "Official Technical Bulletin" below for the description). If you have a problem that is not described by the official technical bulletin, then this harness may not resolve your problem.

This harness plugs into both the existing harness and existing airflow meter connections. No potentially-risky splices are required. A commonly applied alternative fix is to solder a capacitor across the leads of the airflow meter. This works for some folks and maybe worth trying if you are skilled at tinkering and soldering.

Official Technical Bulletin: Condition: "After driving for extended periods, at a constant speed, the vehicle may, on occasion, experience a deterioration of performance which may be accompanied by hesitation or surging. In many cases, after turning off the engine and subsequent re-start or without having taken any action, the symptoms disappear. However, these symptoms may not recur for several weeks or months. To resolve this condition - wire harness Part No. 025.906.302 - should be installed. This harness provides improved signal voltage stabilization."
