How to Fix / Troubleshooting
Safety first: Sensor calibration typically requires specialized tools; do not attempt to recalibrate without BMW procedures.
- Power reset: Turn the breaker OFF for 5 minutes, then ON, and attempt a new charging session.
- Firmware update: Check for and apply any firmware updates that may address sensor calibration issues.
If E19 persists, the current or voltage sensing hardware is likely defective. Replacement of the sensor assembly or main control board must be performed by a BMW-authorized service partner.
