How to reset the tire pressure on a BMW 525?

When the ignition is turned off, press and hold the "Reset" button. Turn on the ignition. Release the "Reset" button and briefly press the "Clock Adjustment" button once. The tire pressure reset light will indicate that it is in reset mode, and after a few seconds, it will return to the normal view. After the reset is complete, you can check the interval mileage until the next maintenance by pressing the "Clock Adjustment" button 4 times. The multifunction display will show the interval mileage until the next maintenance. There is a tire pressure reset switch on the side of the gear lever.
After driving the BMW 525 for so long, I've figured out a simple method for tire pressure reset. First, turn the key to the power position without starting the engine; then press the menu button on the steering wheel to enter the iDrive system, select "Vehicle Settings," find "Tire Pressure Monitoring," click the "Reset" option, and hold the confirmation button for about 5 seconds. Once completed, the light will turn off. Before resetting, make sure all tire pressures are adjusted to the standard values—check the recommended psi or bar in the manual when the car is cold. If the light remains on after resetting, it might be a sensor malfunction or a tire leak, requiring a professional inspection. Handling such minor tasks yourself saves time and effort, but don't compromise on safety.
