The battery died since this is a used B-Class and hasn't been started for 3 years.Why did you have to replace the battery? What happened before this issue?
You can check the voltage of the 12 volt battery by plugging a USB cigarette lighter port with voltage reading . With the ignition switch on it should read at at least 13.8 vdc . With the green " ready " message on dashboard . The voltage should be at least 14..8 volt. Otherwise the high voltage dc to 12volt dc converter is faulty and/or the battery is faulty.The battery died since this is a used B-Class and hasn't been started for 3 years.
Remember when you replace the 12 volt battery. You need to tell the system that you have replaced the battery. You can do this with some obd2 diagnostic/ programmable tool . Otherwise the system may overcharge/ undercharge the new battery and it not last longI am having the same issues so what can I do about this? Take it to the dealership? Is this a common issue when the 12v battery has to be replaced or?
When you replace the 12 volt battery . You need to tell the cpu that you have replaced. You need use a diagnostic db2 scanner/ tool and tel the system of the new battery information like capacity, cca etc . You can't just replace the 12 v battery and forget it like the old school way.I recently replaced the 12V battery in my B-Class, but now it won't start. The dashboard displays 'Visit Shop' and 'Shut Off Engine' messages. Has anyone else had this problem, and what should I do?
