1. Start your car and let it run for a few minutes. This will allow the tire pressure monitoring system (TPMS) to reset itself and detect the new tire.
2. Find the TPMS reset button. In the BMW 3 series, it is usually located in the glove box or the center console.
3. Press and hold the TPMS reset button. You may need to press and hold the button for several seconds.
4. Release the button when you see the tire pressure warning light flash several times. This indicates that the TPMS has been reset and the dashboard light should turn off.
If the tire pressure warning light does not turn off, there may be a problem with the new tire or the TPMS system. In this case, you should take your car to a qualified technician to have the issue diagnosed and repaired.
Note: The steps listed above may vary depending on the specific year and model of your BMW 3 series. Consult the owner's manual for more information on resetting the TPMS.
