VW TDI Cat: Find the Right Catalytic Converter

Hello everyone.

Perhaps someone in this group can help me.
I have a diesel catalytic converter here and I don't know which TDI engine it's for.
It is not suitable for a 1Z or AHU engine.
Sure, here is the translation of the text from German to English:

1. Numbers as follows:

6QO 178 BE
6QO 131 701 H
-> 03:00 AM

Also, here's the number as well.

BQO253059R

Thank you very much for your help.

Detlef.
