Why does the Audi Q3 tire pressure warning light come on when the tire pressure is normal?

[BraydenDella]

Audi Q3 tire pressure warning light comes on when tire pressure is normal due to the following reasons: Tire pressure monitoring system not reset: After inflating the tires, if the tire pressure reset is not performed in time, the system will still retain the previously recorded data, causing the tire pressure warning light to illuminate. Simply performing a tire pressure reset will resolve this issue. Damaged tire pressure sensor: The tire pressure sensor, which monitors tire pressure, is installed inside the tire and connected to the tire inflation valve. If the sensor is damaged during driving (e.g., by hitting a curb), it can trigger the tire pressure warning light. In such cases, the only solution is to replace the faulty sensor with a new one. Method for resetting the tire pressure monitoring system: First, turn on the ignition, then press and hold the tire pressure reset button until you hear a "beep" sound before releasing it. The system will then store the current normal tire pressure data, automatically clear the previous data, and finally turn off the warning light on the dashboard, completing the tire pressure reset process.
