After a regular charge to 75% and a few days without driving, during which an upgrade to 2019.32.12.2 occurred, my M3 announced that regenerative braking was limited, which indeed it was. By the end of the day it had stopped saying that, but regen was still limited, which can be seen in the display with the left part of the dis/charge bar dotted out. Two days later and after a charge to 80% no difference after soft and hard resets. The warning didn't come back for a few days even though the regen remained and remains limited.
Temperature has not been particularly colder than it was before, when it had never showed limited regen except when I charged over 95%. However this is the first time I've been entering a colder season with the M3, which I got in April. It is kept in a garage (I am on the coast in PNW), temps there haven't dropped below 50F yet. I've tried charging it right up until my departure, didn't make any difference. However, while driving I have seen a couple of times when the dots disappeared, but only briefly, like a flickering, and even when they had disappeared it didn't seem to be decelerating any more.
The one thing I haven't tried yet is charging to 95% so it has a legit reason to limit regen and then seeing if it recovers the way it used to.
The regen limitation has not changed at all during driving. Verified that the setting had not changed from standard. This situation bothers me not for any concerns about the battery, but because I want a consistent behavior when I come off the accelerator for my driving reactions.
