I forward this p-mail to the list WITH Peter's permission.  Most of this has been covered, but I
thought that it might be good to put it the archives.

Here is everything that I know:
X simply denotes rebuilt unit in VW's numbering system.  VW made 2 ecu's
by part number  025-906-022  &  025-906-022D
and then they sold a rebuilt version of each which they numbered by
simply adding the X.
VW had two manufacturers for them - Bosch and Triumph Adler - but I
believe both companies made both numbers.
The 022D has a removable chip in it and was sought after by people who
wanted to use the Australian hi-perf chip a few years back but I never
hear about anyone talking about them now and we have never noticed any
difference in driveability between the two units.
We have always found that every 022 and 022D (new or rebuilt) is
interchangeable and syncro v. non-syncro made no difference..

Thank You,  Peter
