2012 Mercedes S550 Base
Hello:
I have 2012 S550 base modem and it popped up Auxiliary battery malfunction message. I change the Auxiliary battery with Original Mercedes battery and sign still comes on in the morning and goes off in the afternoon. Nay ideas what could cause this after replacing the Auxiliary battery

congratulations you are the 12th person with this special mercedes feature fitted on facelift cars that I have read about on this forum - NO ONE has ever replied with the real fault or ANY cure
most waste around 6 months asking and trying pointless ideas - then never respond
I suspect it needs a software update who's ONLY enhancement its to turn off a fake light on the dash
