Replaced Battery to be sure - cleaned up pos cable to bulkhead. Everything works fine, charges etc. but this warning just won’t go after clearing fault code.
Likewise any ideas would be really welcome, thanks.
What voltage are you seeing when the car is running. Plug in one of the cigarette lighter USB chargers that shows you the voltage . If it's not at least 14v when the car is running the warning will show up.
