⚠️ Safety Warnings

Important safety information - read before proceeding

•Ensure vehicle is securely lifted if working on tires.
•Always use proper personal protective equipment when handling tires.

Symptoms

•Tire pressure warning light illuminated on the dashboard
•Possible drop in fuel efficiency
•Uneven tire wear
•Vehicle handling instability
•Warning message on the iDrive display

Diagnostic Steps

1
Scan for Error Codes**: Use an OBD-II scanner to check for any TPMS-related fault codes.
2
Check Tire Pressures**: Measure the tire pressures using a tire pressure gauge to ensure they are at the recommended levels.
3
Inspect Tire Condition**: Visually inspect each tire for signs of damage, punctures, or excessive wear.
4
Reset TPMS**: Attempt to reset the TPMS using the vehicle's settings menu to see if the warning light clears.
5
Inspect TPMS Sensors**: Check the battery status of each TPMS sensor, as low battery can cause malfunction.
6
Examine Wiring and Connections**: Inspect wiring and connections to the TPMS module for damage or corrosion.

Solution

1. Preparation

Gather all necessary tools and parts.
Park the vehicle on a flat surface and ensure the engine is off.
Gather safety gear (gloves, safety glasses).

2. Check and Inflate Tires

Sub-steps:
1. Remove valve caps from each tire.
2. Use a tire pressure gauge to measure the pressure of each tire.
3. Inflate tires to the manufacturer’s recommended pressure levels (check the driver’s side door jamb for specifications).
4. Reinstall valve caps.

3. Reset TPMS

Sub-steps:
1. Turn on the vehicle's ignition without starting the engine.
2. Navigate to the “Vehicle Settings” on the iDrive display.
3. Select “Tire Pressure Monitor” and then “Reset.”
4. Confirm the reset and wait for the system to initialize.

4. Replace TPMS Sensors (if needed)

Sub-steps:
1. Remove the tire from the wheel using a tire changer.
2. Detach the TPMS sensor from the valve stem.
3. Install a new TPMS sensor, ensuring it is securely mounted.
4. Reinstall the tire onto the wheel and balance if necessary.

5. Verification of Repair

Sub-steps:
1. Start the vehicle and check if the tire pressure warning light is off.
2. Test drive the vehicle for a short distance to ensure the TPMS is functioning correctly.
3. Monitor tire pressures after a few days to ensure they remain stable.
