What problems can a malfunctioning auxiliary battery cause in a Mercedes GL?
Years 2012-2019

Answer

On a Mercedes GL, an auxiliary battery is installed for the operation of accessories. Theoretically, the vehicle can also travel without it, but in reality, we do not know how a system designed for two batteries reacts when one is removed. In fact, when the auxiliary battery is malfunctioning or defective, a warning message will appear. Of course, the vehicle travels without problems even if the auxiliary battery is damaged; at most, some electronic accessories will be affected and will have difficulty functioning simultaneously.
