Auxiliary battery malfunction but start/stop still functioning properly.
My wife’s 2016 GLC300 with 18,500 miles suddenly showed Auxiliary battery malfunction, it is rarely driven, in fact from September of 2023 till end of January 2024 it sat idle in the garage.
started driving it again in February, mostly short trip. Also testing new dashcam and plugging it in the 12V cigarette lighter in the back seat.
The auxiliary battery was replaced by the dealer in early 2021 because the start/stop was not working properly.
now the start/stop is working but the display shows the auxiliary battery malfunction.
Anybody with the same problem?
Have not taken it in for diagnosis yet.
