Solution

1. Preparation

Gather necessary tools: OBD-II scanner, tire pressure gauge, TPMS tool, and a basic socket set.
Park the vehicle on a level surface and ensure the engine is turned off.
Ensure that all tires are at the recommended pressure levels before proceeding.

2. Resetting the TPMS

Access the TPMS menu:
- Turn the ignition to the "ON" position without starting the engine.
- Navigate to the vehicle settings on the iDrive system.
- Select "Vehicle Status," then choose "TPMS."
Reset the TPMS:
- Select the option to reset the TPMS.
- Confirm the reset when prompted by the system.
Drive the vehicle:
- Drive for a few minutes to allow the system to recalibrate and recognize the tire pressures.

3. Sensor Replacement (if necessary)

Remove the tire:
- Use a jack to lift the vehicle and securely support it with jack stands.
- Remove the wheel lug nuts using a socket wrench and take off the tire.
Replace the TPMS sensor:
- Locate the TPMS sensor mounted on the valve stem.
- Disconnect the sensor from the valve stem and remove it.
- Install the new sensor onto the valve stem, ensuring it is securely fastened.
Reinstall the tire:
- Place the tire back onto the wheel hub.
- Hand-tighten the lug nuts and then torque them to the manufacturer's specification (typically around 80-100 ft-lbs).

4. Final Checks

Recheck tire pressures after installation and ensure they are correct.
Use the TPMS tool to verify that the new sensor is communicating properly with the vehicle.
