Does the end pot from ABZ,AEM,AGH,AKG fit AEW???

Hello, I bought a final pot with the part number:
4D0 253 609 C It is suitable for the engine identification letters: ABZ,AEM,AGH,AKG
But I have a 3.7 L AEW PartNo.: 4D0 253 609 D

1 Question: Fits the pot on my car
2 Question: Which models include the engine identification letters?
3 Question: Do I need to have it entered???

It looks pretty good that this one would fit. There are only other holders for the rubbers!
The pipe diameter between the centre and rear silencer is 55mm(outside) and the one from the new exhaust 60mm(outside). Shouldn't it be a good match???
