Well my turn - Replaced the battery. Once coding and register was confirmed (using Bimmergeek), I all of a sudden get increased charge voltage at 14.8V vs 14.3 isch with the worn out battery. Temperature has fallen to below 0 which apparently is being compensated by the ECU, but reading this thread an old battery apparently should be compensated with higher charge voltage puzzles me. I also went from AGM to flooded which again should lower the voltage if anything.
Yours has been fine since replacement or noticed any further odd behaviour Redd?

In the same boat as both of you, except I live in SoCal.
Replaced the battery and get the discharged warning. Car has been on a tender ever since.
