I love my BMW service dept but I think BMW leaves their service dept's in the dark with the mild hybrid systems. They work on PFM lol. I learned quickly you can't leave a trickle/smart charger on the mild hybrids without potentially damaging both the 12v and 48 volt battery.
I hope it works out for you.
