It reports on the display between the clocks, 12v battery low. Charge by driving. This warning comes up after about three days of the van not being used. I start the engine and it goes away. My van is used mostly at weekends as it’s my fishing van.could you elaborate please? what's reporting "low battery charge" a message on the MFD? And what's a "Driving error"? What is the source of this info?
