How to Fix / Troubleshooting
Safety warning: Do not interrupt firmware updates once started. Electrical safety functions may be impaired if firmware is corrupted.
- 1. Attempt a controlled reboot: Use the app or internal reset button to restart the charger. If unavailable, power-cycle at the breaker.
- 2. Retry firmware update: If E16 appeared after an update, use the official Land Rover update tool or app to reapply the latest firmware, following instructions carefully.
- 3. Use a stable power source: Ensure the charger is not losing power during updates. Avoid updating during storms or known grid instability.
- 4. If update fails repeatedly: Do not attempt unofficial firmware. Contact Land Rover support for a service firmware image or on-site reprogramming.
- 5. If E16 persists after successful reflash: The control board's flash memory may be defective and require board replacement.
