Hi @T5-T6-Schnappi
Thank you very much for your help. Before buying any new modules, I removed the headlight and checked the part numbers of the modules I transferred from my original US headlights.
I currently have:
HIR: 31446806
FFM: 31468410
LCS: 31395946
I also tested two different DRL LED boards (9 LED and 10 LED versions), and neither of them worked in the EU headlight.
I also did an important test: I reinstalled my original US headlight with these modules and everything works correctly, including the DRL/Thor Hammer and front indicator. So the modules themselves seem to be functional.
From what I found, 31446806 appears to be a newer replacement/supersession for one of the module numbers you listed.
Do you think my current modules should work with the EU headlights after the correct HCM software reload/initialization?
Or do I actually need to replace them with the older part numbers you listed (31395943 / 31395944 / 31395945 / 31395946) and then perform a software reload?
I'm trying to avoid buying another complete set of modules if my current hardware is already compatible and only needs the correct software.
Thanks again!
