There are two known serial errors:
- Vehicles with a 22 kW charger suddenly do not charge at all or only charge in one phase
- The problem here is the 22 kW charger of the first series "D01"
- These were installed in every vehicle by the factory
- The "D02" series was only installed when the charger got replaced
- The problem is an built-in capacitors in the input filter of the 22 kW charger (22kW Charger - BRUSA NLG664 Teardown & Error Analysis)
- These burst at some point and kill the corresponding phase
- These were installed in every vehicle by the factory
- The only way to prevent this error is by buying a vehicle with a D02 charger
- I strongly advise against third-party solutions
- The problem here is the 22 kW charger of the first series "D01"
- The vehicle can no longer be driven and charged after a long period of it beeing parked
- The HV battery is deeply discharged
- The reason for this is that the 12V battery is defective and has therefore drained the HV battery
- This error can be prevented by replacing the 12V battery every 3-5 years
- Affected batteries have to be opened and charged manually (smart ED3 17.6kWh battery repair (feat.P18051C / bricked BMS))
- Be careful not to break the current sensor in this process
- The HV battery is deeply discharged
