What is the method to reset the tire pressure light on a BMW 320i?

BMW 320i tire pressure light reset method is as follows: Ensure the tire pressure of all four tires is normal; Locate the BC button on the left side of the steering wheel; Use the scroll wheel to select tire pressure reset; Press the BC button to confirm and reset the tire pressure light. Tire pressure refers to the air pressure inside the tire, which is closely related to vehicle performance, such as comfort and load capacity, and also affects tire lifespan; Low tire pressure increases tire deformation and contact area, accelerating shoulder wear; High tire pressure increases the load on the vehicle during driving and accelerates tread wear.
I remember dealing with the tire pressure light issue on the BMW 320i was quite straightforward, but it had to be done step by step. First, check if the tire pressure meets the standard—the recommended values are usually listed on the door frame label, around 32-35 PSI. If it's low, use a pump or go to a gas station to inflate them. After filling, start the engine and operate from the driver's seat: for most models, navigate through the iDrive system to the 'Vehicle Status' or 'Tires' option in the settings menu, select the 'Reset TPMS' option, and confirm. Drive for a few minutes, and the light should turn off. If it doesn’t work, the sensor might be dirty or the battery could be dead, requiring a visit to the dealership. Whenever I see the light on, I always pull over to check the pressure first—otherwise, driving at high speeds poses risks, accelerates tire wear, and increases fuel consumption. During regular maintenance, ask the technician to inspect the system to prevent minor issues from escalating. In short, make it a habit—don’t ignore this little alert, as it can save you a lot of trouble.
