How do I reset the oil change light in my Audi A8?

I recently changed the oil in my Audi A8, but the oil change light is still on. How do I reset it?

To reset the oil change light in your Audi A8, start by turning the ignition to the 'on' position. Next, press the 'car' button on the center console until the 'service due' message appears. Then, press and hold the 'ok' button for about 5 seconds until a new menu appears. From this menu, select 'reset oil change interval' and confirm the reset. Your oil change light should now be reset.

Firstly, make sure that you have actually changed the oil in your Audi A8. If you have, and the oil change light is still on, try disconnecting the battery for a few minutes and then reconnecting it. This should reset the system and turn off the oil change light. If that doesn't work, it's best to take your car to a certified mechanic for further assistance.
