Hi,I have problem with my bmw i3 2017. I have received the code shown above and the dashboard says “drivetrain malfunction” I have also checked all the cables if there is any damage or moister including the wire going to the battery. I’ll attach a picture of AC/DC inverter that shows there is a high voltage of 14.8 on the plugs of the battery jump start plug. Please give any advice if it’s a voltage problem and is it normal for that voltage percentage.On the 12 volt battery shows above 14V
