Bosch Parts: Ambiguous Numbers?

Hi.

Here's some information I have about a set of Düsen:

1 Main injector, VW/Audi, part number 028130201T, Bosch part number 0432193747.
3 injectors, VW/AUDI, part number 028130201S, Bosch part number 0432193745.

Unfortunately, the BOSCH ECAT does not return any results for the given BOSCH part number.
He's giving me DIFFERENT Bosch numbers for the VW part numbers.
... 746 and ...
... 744

Does anyone have experience with assigning BOSCH part numbers?

The two Bosch part numbers definitely do not exist in the 2003 Duesen catalog.

Thank you.

but in which catalog??? (oh, now I see, the DUESEN catalog).

Those special characters are being lost/disappearing!

Are the others (each one lower by 1) available?

Those must be nozzles from AFN.

Yep, they exist.
