Hello and greetings to everyone as I'm a fresh user here from Estonia!

My 1997 2.5 TDI V70 recently died on the highway, because it couldn't get any more fuel from the tank to the engine. They checked at the workshop that the fuel filter was almost completely dry. So as it happened while driving, it can't be an immobiliser fault, but rather the high-pressure fuel pump fault.

So my question now: is it necessary to take off the old pump and find some specific serial number from it before I order another refurbished one?
Or is it just already enough to use the OE-code like this: 1275497 or 8111112 or the Bosch code, which looks like this: 0460415990 and I don't need to follow the specific serial number?

Why I'm asking it, is because I recently had to replace the ABS module with pump (OE code: 9467582) and it needed to have the same specific serial number as the old one I had.


Thanks for every user for the help!
