Finding the right airbag module

[misterstrusis]

Hello,
I bought an E85 few months ago with fault code about the left side B pillar airbag module. After doing some research I found that multiple people have had this problem and that its possible to buy an used module and program it to the VIN.
I found a guy in my country that sells this module. The part number is the same but all of the other codes are different (codes above the barcode and the "Serien nr"). Do all of these codes need to match or only the part number? I tried but cannot find an answer about this online.
Any advice would be appreciated.

6928571 is the only number you need to worry about.

Real OEM parts site shows what modules are exchangeable with your original module so you are not limited to a like for like exchange. Replacements will of course be required to be coded with your Vin number
