Yes, I have, and so have many others. It worked for me. There is also the
do-it-yourself capacitor fix, for a fraction of the cost. This has been covered many
times. Try a search of the archives for "AFM capacitor fix".

Has anyone tried VW part number 025 906 302A in the wiring harness between the air
flow sensor and the wire harness?  The fix provides improved signal voltage
stabilization.  I ran into this bulletin on the microfiche from ALLDATA.  The bulletin
was dated April 30, 1992.  Superseded Technical Bulletin 92-01.

For all water cooled engine vanagons.
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.  These symptoms may not re-occur for several
weeks or months.

The schematic shows it to be some type of transformer.
