I may have a clue.  In the VOA price list, there are three 021-906-031
injectors listed:
021-906-031
021-906-031A
021-906-031B

The most current Bosch Injection book interchange lists the 021-906-031A
injector for the late 92 VR6 Passat (from VIN 31-N-120001 or Oct 91)(Bosch
0280 150 953) with Digifant.

Early 92 VR6 Passats (also w/Digifant) used Bosch 0280 150 929 thru VIN
31-N-120000 or Oct 91.  Unfortunately, the Bosch interchange does not give
the Original VW Part Number.  I'd be willing to bet that the 021-906-031
yer looking at is this injector.  Ask the person to look for the Bosch
number on the injector to confirm this.  It should have both the VW and
Bosch # imprinted on the injector itself.

I have a large number of original VW films to work with, but no Passat
films (never had the need for them to be honest).  Does anyone have a 1992
Passat film to confirm my "wild speculation"?

As to workability in Van Digifant, I'd be inclined to say no.  These
injectors are probably designed for a smaller bore cylinder and MAY run
leaner than their 4 cylinder counterpart.

As to why VW would use a "021" prefix for the Watercooled Digifant
Injectors, who knows, ask the Kaiser!  You should know that after all these
years Volkswagen does a lot of things that make no sense, right?.........;-)
