Speaking of batteries and charge. My 2018 LCI i8 coupe intermittently gives the error ' Drivetrain. No restart'. The associated OBD2 code was 1D3702 Power Management, Battery: Faulty Charge By High-Volt Battery ( among others like Standby Current Violation) Then sometime the error spontaneously disappears and the car drives perfectly and can restart. Pat (Patonlinegarage) ,ever so kindly, suggested I consider the 12v battery . I just did a load test and the battery readings are ok with a state of health at 91%. Can it still be the 12v causing the error if all the measurements during battery testing seem fine? My car was bought in the UK and still under warranty but I shipped it to Trinidad and the local agents refuse to touch it.
