There’s no aux battery malfunction message that I know of.
only the red background Battery image caution if the battery or the alternator has failed or the white battery image plus “visit workshop” if it’s failing.

2010 GL550 with 133k miles. I'm currently getting the "Auxiliary Battery Malfunction" message in my HUD display. I'm guessing it's original and needs to be replaced. I've read other threads stating that's not always the case. Guess I'll find out when I replace it. I've been driving with that message for the last month and haven't experienced any unusual issues.
