How to reset the tire pressure monitoring system on an Audi A3?

I just purchased a used Audi A3 and the tire pressure warning light is on. How can I reset the TPMS to ensure accurate readings?

To reset the TPMS on your Audi A3, you will need to first check the tire pressure of all four tires using a tire gauge. Then, locate the TPMS reset button, usually under the steering wheel or near the glove box. With the ignition on, hold the button until the TPMS indicator flashes three times, indicating a successful reset.

Another option is to use an OBD2 scanner to reset the TPMS on your Audi A3. Plug the scanner into the OBD2 port, usually located under the dashboard, and follow the instructions to reset the TPMS. This method may require a bit more technical knowledge, so make sure to read the instructions carefully.
