Ok. Those don't have any direct correlations. At this point you've purchased a new RLS, checked wires and check voltage. My only action from here would be updating the LM/RLS and hoping it's a software issue.
Is your alternator still providing less than 13v while driving? It should be around 13.5v. I'm only assuming but your code comes up before car is started and once started and you clear code it's good until the next shut down. That takes everything out the equation and leaves the modules and ensuring your battery has a charge for self tests. If you don't know can you check to see when the code actually activates.
There is no software update for my car, all units is updated to latest data. I think error comes after wake up, last time i was checking code, i scanned car at my home, deleted code, than i was driving 10km to store, leave car there about an 1h, then i came back, started car and scanned it again at parking lot, the code was back.
I Didnt loged battery voltage anymore.

I found couple used LM2 modules at local used parts sellers, they ask 100€ , i will try to make offer, if used part will not solve my fault code, i will return it with full refund.
Update.
Got my LM today, installed. Read faults from it. I think new LM already have same fault code. But i hope , im wrong. I add photo of faults.
I changed VIN via Tool32, write FA to LM via NCS, code it to my VO . Deleted faults. Left my car for a sleep for night. At morning i will read faults again and update post.
No, these faults is not mine. They was was in LM when i got it. LM is used not new. All faults cleared. I was driving about an 1h yesterday with spare LM, 0 faults, like with my native LM. But morning scan 1 fault, same .
