Just found this info in the digital manual for my ctek charger (the AGM part is missing from the paper manual I think):
I think they're saying that the 14.7V snowfling mode is recommended for AGM batteries regardless of temperature.
Strange that the new BMW charger doesn't support charging at 14.7V.
NORMAL MODE:
Battery size 14–140 Ah / Mode 14.4V/4A
Normal mode for wet batteries, MF and for most GEL batteries.
SNOWFLING MODE:
Battery size 14–140 Ah / Mode 14.7V/4A
This mode is recommended for charging batteries at temperatures lower than +5°C. It is also recommended for many AGM batteries. This setting is not recommended for maintenance charging when the temperature temporarily exceeds +5°C. Here we recommend the 14.4V/4A or 14.4V/0.8A mode.
