Solution

1. Preparation

Tools Required: OBD-II scanner, tire pressure gauge, jack and jack stands, socket set, torque wrench.
Ensure the vehicle is parked on a level surface and the engine is turned off.
Disconnect the battery to avoid any electrical issues during repairs.

2. Inspect and Replace Faulty Sensors

Remove the Wheel:
- Use a jack to lift the vehicle and place it securely on jack stands.
- Loosen the lug nuts and remove the wheel.
Access the TPMS Sensor:
- Locate the TPMS sensor, usually mounted on the valve stem inside the tire.
- If needed, deflate the tire slightly to ease removal of the sensor.
Inspect the Sensor:
- Check for any visible damage or corrosion on the sensor.
- If damaged, remove the sensor by unscrewing the retaining nut and disconnecting it from the valve stem.
Replace the Sensor:
- Install a new TPMS sensor, ensuring it is compatible with the BMW system.
- Reattach the retaining nut and ensure it is torqued according to specifications (usually around 4-6 Nm).

3. Recalibrate the TPMS

Reinstall the Wheel:
- Put the wheel back on the hub and hand-tighten the lug nuts.
- Lower the vehicle and torque the lug nuts to the manufacturer's specifications (usually around 120 Nm).
Reconnect the Battery:
- Reconnect the vehicle's battery and ensure all connections are secure.
Perform a TPMS Reset:
- Follow the manufacturer's procedure to reset the TPMS system, which may include using the OBD-II scanner.
