Under piston squirters - part number

Hi Peeps

Just had sporadic oil pressure issues, followed by a balance shaft failure, seized solid,

New/2nd hand parts acquired but struggling to find the under piston oil squirters,

I have been given a part number of 06F103154 direct from car reg, 

I'm finding numbers of -

06F103154a

06F103154b

06F103154c (listed against the 1.8t)

Rev A and Rev B cross reference i believe, but can't find any immediately available but I can find rev C available but its lited against a 1.8t engine? 

is it the same part but different revisions or will the C be completely different?

It's a 2.0lt BWA engine 2006
