The X suffix is usually used to denote a rebuilt part.  That is the
difference between the 022D and 022DX. D is new, DX repaired/rebuilt.

There are 3 different ECUs that work with the 2.1 Digifant.

Triumph-Adler Digifant
Bosch -022
Bosch -022D

I don't care as much for the Triumph-Adler version and it is less common
as the other 2. The 022D is the latest  and the only one that can use
the modified chip that has been around for a while. With an admittedly
small sample set, I have personally seen more dead TA ones than the
other 2 combined but all fail and I have had dead ones of all types.
