The VW Euro parts data I checked showed only the 022D version for Syncro
with 2.1 MV engine. The VW parts data typically lists only the current
replacement part numbers and does not mean that some other number was
never used. For some parts a revision history with the various parts
versions given but I did not find one for ECUs. The same 022D was the
only part listed for 2wd models with that engine. My parts data source
is somewhat out of date.

I have seen examples of the 022 and 022D that did not have the VW part
number on them at all, only  Bosch numbers. The 022(D)  is part of a VW
number and may be missing. I suspect that Bosch sold replacement ECUs in
a generic form to parts houses and these did not have the VW number. If
anyone has the Bosch part numbers for the 022 and 022D please post them.
