How can I reset the service light on my Audi A4?

I recently purchased an Audi A4 and the service light has come on. I want to know how to reset it without having to bring it into the dealership.

To reset the service light on your Audi A4, first make sure the ignition is turned off. Then, press and hold the reset button on the instrument panel. While holding the button, turn the ignition to the 'On' position, but do not start the engine. Continue holding the button until the service light starts flashing. You can then release the button and turn off the ignition. Next time you start the car, the service light should be reset.
