Not saying the battery is your definitive cause. But worth taking a look at.

Funny thing was that I posted this about 3-4 years ago in two other BF threads.. and then forgot about it!!
The BMW charge/voltage control system may in fact starve some items on the buss when the battery is low.
I suppose you could do a deep charge with a proper charger, see if that changes the behavior. If it fixes fora a while, but then it returns, but a new battery.
