how to deal with BMW X3 G01 (2018-2024) tire pressure monitoring system issues

Solution

1. Preparation

• Tools Required: OBD-II scanner, TPMS tool, tire pressure gauge, torque wrench.
• Ensure the vehicle is parked on a flat surface and the tires are cool.
• Disconnect the battery before working on the TPMS system to prevent any electrical shorts.

2. Replace Faulty Tire Pressure Sensors

1. Remove Wheel:

   • Loosen wheel lug nuts with a socket set.
   • Lift the vehicle with a jack and secure it on jack stands.
   • Remove the wheel completely.

2. Access TPMS Sensor:

   • Remove the valve stem cap and use a TPMS tool to loosen and remove the sensor from the tire.

3. Install New Sensor:

   • Replace the old sensor with a new one, ensuring to use the correct sensor compatible with the BMW X3 G01.
   • Tighten the sensor to the manufacturer's specified torque (typically around 4-6 Nm).

4. Reinstall Wheel:

   • Place the wheel back on the hub and hand-tighten the lug nuts.
   • Lower the vehicle and then torque the lug nuts to the manufacturer’s specifications (usually around 120 Nm).

3. Reset TPMS System

1. Reconnect Battery:

   • Reconnect the battery terminals securely.

2. TPMS Reset Procedure:

   • Turn the ignition on without starting the engine.
   • Use the iDrive system to navigate to the "Vehicle Settings" menu.
