Injector part numbers

[Campo1980]

I have recently developed a knock on start up on my 1.8 tdci t230 and when I had a look at my injectors there was 2 different types. Part number on 2 of them ended in AB and the other 2 end in AD.
Is this normal? If not what should they be?

are the other numbers/letters the same?....parts often have similar last letters, might have had 2 changed at some time
