This is pure speculation, but I betcha what Bentley is showing is the NK
Tranny Valve Body in their picture.  VW only lists one replacement
assembly that fits both NH & NK Trannies:

090 325 037 B (Code Letter FFB, whatever that means) and it probably has the
larger piston.

010 325 105 AA is most likely just the valve body casting number and which
would be considered just a component of an entire assembly.  This number is
not in the VW Part Number database I have and I'm not surprised because of
it probably being a component number for assembly.

Darryl at AA Transaxle could probably have better information.
