How do I reset the tire pressure sensor in my Audi A4?

I recently had my tires changed and now the tire pressure warning light is on in my Audi A4. How can I reset the sensor to turn off the warning light?

To reset the tire pressure sensor in an Audi A4, start by turning on the ignition but do not start the engine. Press the diamond-shaped button on the center console until 'SETTINGS' appears in the driver information system. Use the thumbwheel to select 'Service' and then 'Tire pressure monitor'. From there, you can reset the tire pressure sensor by following the instructions on the display.

If the tire pressure sensor is not resetting, it may be due to a faulty sensor. In that case, it's best to take your Audi A4 to an authorized dealer for further diagnosis and potential replacement of the sensor.
