Does the fuel injection pump fit?

Hello, I've used the search function, but unfortunately, I haven't found anything. So, here's my question: Can I install the fuel injection pump from a 90 HP Passat TDI (with AHH engine code) into my 110 HP Passat TDI (with AFN engine code)? Are there any differences in the structure, or should I expect a performance decrease? Or does it simply work because it's the same [thing]?

Greetings from the Harz region.

Hi,

I have a bad feeling that this question will lead to the same problems as here.

Okay, first of all:
Do you have any ET or Bosch part numbers for the pumps?
That would significantly help the situation.

Generally, it might be possible to get this combination working, but I wouldn't bet on it.
