All the accessories are off. Engine is running. The report is "High power consumption". What could it be?
Electrics, ECU, Warnings & Lights
Probably battery low and needing a charge especially if used on short journeys and with so many drains on batteries in this weather with heater , demister , headlights etc on .
You need a live data scan,
But just guessing the battery could be faulty making it resistant t charging.
