Solution

1. Preparation

Gather all necessary tools and equipment.
Ensure the vehicle is parked on a flat surface and the ignition is turned off.
Gather safety equipment, including gloves and safety glasses.

2. Tire Pressure Adjustment

Sub-step 1: Remove valve caps from all four tires.
Sub-step 2: Inflate or deflate each tire to the manufacturer's recommended pressure (found on the driver’s door jamb).
Sub-step 3: Replace the valve caps securely.

3. Sensor Inspection and Replacement

Sub-step 1: If any tire is found to have a damaged sensor, remove the tire from the wheel following standard tire removal procedures.
Sub-step 2: Detach the TPMS sensor from the tire valve stem.
Sub-step 3: Install a new TPMS sensor (ensure it is compatible with the G30/G31 model).
Sub-step 4: Reassemble the tire onto the wheel and balance it as necessary.

4. System Reset

Sub-step 1: Turn on the vehicle's ignition without starting the engine.
Sub-step 2: Access the vehicle’s menu system using the iDrive controller.
Sub-step 3: Navigate to the TPMS settings and select "Reset" or "Initialize."
Sub-step 4: Confirm the reset and wait for the system to complete the calibration process.

5. Final Check

Sub-step 1: Monitor the dashboard for any error messages or warning lights.
Sub-step 2: Test drive the vehicle to ensure the TPMS light does not reappear.
