Diesel injectors 642 CDI

[142 TPL]

I am after some help here. I am buying a couple of injectors for my car and the bosch part number is 0445115064 but the shop is trying to give me 0445115063. They are telling me that the two are the same. Is this correct or are they different. Would I need to change all of them. I know that they need to be programmed.
Thanks
Sorry if you have read this on another forum but I need all the help I can get

Do you have the mercedes part number? I would get the correct part number as unless it is a superceded part, one digit can make all the difference!

You only need to change the faulty one, no need to change them all

A6420701387 is the Merc part but the bosch number is on there too
