BCM Replacement Help!

Hi All,
After a long battle with some Modified Full LED Headlights, that have not worked properly ever, I am starting to think they have damaged by BCM on my 2012 Evoque SD4. Today I stripped the front end and put the old headlights back, but the car is still not powering on the Drivers Side Parking Light or letting me re-enable the Protected Circuit, despite checking all the wiring again and fitting back the original headlight that was there before these Facelift Mod Lights ruined it all. Everything else is fine, but the Drivers Side PArking Light / DRL will not illuminate.
I would like to replace the BCM to be sure, but when searching on eBay, most BCMs Part Numbers are EJ32-14F041-AC or GJ32-14F041-AC and mine is BJ32-14F041-AC …All other digits in the part number are same. Am i correct to assume the BJ, EJ and GJ are simply parts that superceded the previous ones on newer models, or do i need to find the exact BJ32-14F041-AC ?
Thanks!
Owen
