Solution

1. Preparation

Tools Required: Tire pressure gauge, OBD-II scanner (optional, for advanced diagnostics)
Ensure the vehicle is parked on a level surface and the ignition is in the "Off" position before beginning.

2. Correct Tire Pressures

Check Tire Pressures:
- Use a tire pressure gauge to measure the pressure of each tire.
- Inflate or deflate tires as necessary to match the manufacturer’s recommended pressure, typically found on the driver’s door jamb.

3. Reset TPMS

Turn on Ignition:
- Insert the key fob and turn the ignition to the "On" position without starting the engine.
Access the TPMS Reset Function:
- Locate the TPMS reset button, typically found under the steering wheel or in the glove compartment.
- If your model does not have a physical button, the reset can be performed through the iDrive system. Navigate to "Vehicle Information" > "Tire Settings" > "Reset Tire Pressure."
Press the Reset Button:
- Hold down the TPMS reset button until the TPMS light blinks three times, then release it.
- If using iDrive, confirm the reset on the screen.

4. Verify the Reset

Turn Off the Ignition:
- Turn off the ignition completely and wait for a few seconds.
Restart the Engine:
- Start the engine to check if the tire pressure warning light has turned off.
