The battery monitoring sensor (BMS) has registered a hardware fault. The sensor monitors the battery's condition, and the engine control module uses that information to regulate alternator charging. The fault switches off the automatic start/stop function.

- 3If you have a diagnostic tool: read the battery voltage in live data and check that it follows the vehicle's other voltage readings
- 4Check the connector at the battery monitoring sensor for loose contacts and corrosion
- 5Erase the fault code and road test the car with automatic start/stop to see whether it returns
- 6If the fault returns, have a workshop replace the battery monitoring sensor
