Solution

1. Preparation

Ensure all tires are at the correct pressure as specified on the driver’s door jamb sticker.
Gather necessary tools: key fob, OBD-II scanner (optional), and a tire pressure gauge.

2. Resetting the TPMS

Turn on the Ignition:
- Insert the key fob into the ignition and turn it to the “ON” position without starting the engine.
Access the TPMS Reset Function:
- Navigate to the vehicle settings using the iDrive system. This can typically be done by selecting “Vehicle Info” or “Settings” on the main screen.
Select TPMS Reset:
- Look for the option labeled “Tire Pressure Monitor” or “TPMS.” Select this option.
- Choose “Reset” or “Initialize” from the menu. Confirm the action when prompted.
Start the Vehicle:
- After the reset, start the engine and allow it to run for a few minutes. The TPMS light should turn off if the reset is successful.
Manual Reset (if iDrive is unavailable):
- If no iDrive system is present, press and hold the TPMS reset button (usually located beneath the steering column) until the light blinks and then turns off.

3. Final Checks

After resetting, check if the TPMS light remains off while driving.
