How to reset the warning light after tire repair?

[VanPiper]

It is necessary to check whether the tire pressure of the wheel is high or low. You can slightly increase the tire pressure to the safe value. Press the tire pressure warning light reset button of the vehicle for 3 seconds. The tire pressure warning will be reset, and the problem will be solved. If the tire pressure is displayed as too low, you need to reset it and then drive the car for a while.

Last time after I got my tire repaired, the tire pressure light kept staying on. Turns out you need to manually reset the system after a tire repair. First check if the actual cold tire pressure of all four tires meets the standard - usually there's a reference value on the driver's door frame or fuel cap. After confirming proper tire pressure, turn the ignition on without starting the engine, then locate and hold the tire-shaped button near the steering wheel for 5 seconds (for German cars it's often near the gearshift). When I did this, I waited three minutes until the dashboard beeped and the light went off. If there's no physical button, try looking for 'Vehicle Settings - Tire Pressure Calibration' in the infotainment screen. If the light remains after driving 10km, the sensor might have been damaged during repair or it's a system false alarm - you'll need to visit a shop for a computer reset.

The tire pressure warning light after a tire repair is essentially due to the tire pressure monitor not recognizing the new data. I've encountered this three times, and twice it resolved itself by driving on the highway: driving steadily on an expressway for 20 minutes allows the system to relearn. Note that you should first confirm the tire pressure is accurate with a mechanical gauge when the car is cold (don't trust the digital display on the air pump), and the difference between the repaired tire and others should not exceed 0.1 bar. My neighbor's car was even more extreme: disconnecting the negative battery terminal for 15 minutes and then reconnecting it, effectively forcing a reboot of the car's system. If none of these work, it's likely that the sensor on the valve stem was damaged during tire removal, especially in older cars where the rubber is prone to cracking. Replacing the sensor costs around 200 yuan.

As someone who has experienced five tire repairs, here are some key reminders: After a tire repair, the warning light will definitely stay on when you drive off immediately (the system takes 30 seconds to 2 minutes for self-check). Before the light goes off, check if the tire pressure values are displayed—if one tire's data is missing, it means the sensor's battery is dead or the sensor is damaged. Last time, my warning light stayed on for three days after a repair, only to find out the repair shop forgot to screw the sensor back onto the valve stem! Be extra cautious in winter—sudden temperature drops can trigger tire pressure alarms, so after a repair, inflate the tire 0.2 bar above the standard pressure. If your car has a spare tire, low pressure in the spare can also trigger an alarm (don’t ask how I know).
