⚠️ Safety Warnings

Important safety information - read before proceeding

•Always wear safety glasses when working with tires.
•Ensure the vehicle is securely lifted if working under or around it.
•Check that the tire pressure warning light has turned off.
•Test drive the vehicle to confirm that the ride feels normal.
•Monitor the tire pressure readings through the vehicle's display for accuracy.
•Recheck tire pressures after a short drive to ensure they remain stable.
•Regularly check tire pressure at least once a month.
•Rotate tires according to the manufacturer’s recommended schedule.
•Inspect tires for wear and damage during routine service.
•Use high-quality tires that are compatible with TPMS systems.
•Address any warning lights promptly to avoid further complications.

Symptoms

•Tire pressure warning light illuminated on the dashboard
•Possible fluctuation in tire pressure readings
•Warning message displayed on the vehicle screen
•Handling or ride comfort may feel abnormal
•Potential decrease in fuel efficiency

Diagnostic Steps

1
Check the tire pressures with a reliable tire pressure gauge to ensure they are at the recommended levels.
2
Use a BMW diagnostic tool to read TPMS fault codes.
3
Inspect all tires for visible damage, punctures, or abnormalities.
4
Verify that the TPMS sensors are functioning and not damaged.
5
Check the vehicle’s battery voltage, as low voltage can affect TPMS operation.
6
Ensure that the wheels are equipped with TPMS sensors compatible with the vehicle.

Solution

Solution

1. Tire Pressure Adjustment

Sub-steps:
1. Remove the valve cap from each tire.
2. Use a tire pressure gauge to measure the pressure in each tire.
3. Inflate or deflate tires as necessary to match the manufacturer’s recommended pressure (found on the door jamb).
4. Replace the valve caps securely.

2. TPMS Reset

Sub-steps:
1. Turn on the ignition without starting the engine.
2. Access the vehicle settings on the infotainment screen.
3. Navigate to the 'Tire Pressure Monitor' section and select 'Reset'.
4. Confirm the reset and allow the system to recalibrate.

3. Sensor Inspection and Replacement

Sub-steps:
1. Remove the tire from the wheel using a tire changer if necessary.
2. Inspect the TPMS sensor for any visible damage or corrosion.
3. If damaged, replace the TPMS sensor with a new one.
4. Reinstall the tire and ensure it is properly balanced.

4. Battery Check (if applicable)

Sub-steps:
1. Check the vehicle battery voltage using a multimeter.
2. If the voltage is below 12.4 volts, charge or replace the battery.
3. Retest the TPMS function after battery service.
