Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a level surface with the engine off.
Safety glasses and gloves should be worn for protection.

2. Inspect and Inflate Tires

Sub-steps:
1. Use a tire pressure gauge to measure the pressure of each tire.
2. Inflate tires to the recommended pressure as specified on the driver's door jamb sticker.
3. If any tire is damaged, replace it as necessary.

3. Check TPMS Sensors

Sub-steps:
1. Remove the tire if necessary to access the TPMS sensor.
2. Inspect the sensor for any physical damage or corrosion.
3. If the sensor battery is dead (usually after 5-10 years), replace the TPMS sensor.

4. Reset TPMS

Sub-steps:
1. Turn on the ignition without starting the engine.
2. Navigate to the vehicle settings on the iDrive system.
3. Select the "Tire Pressure Monitor" and then choose "Reset."
4. Confirm the reset and turn off the ignition.

5. Test the System

Sub-steps:
1. Start the engine and drive the vehicle for a few minutes to allow the TPMS to recalibrate.
2. Monitor the dashboard for any error messages or warnings.
