How can I reset the lane departure warning system on my Audi A8?

I recently had maintenance done on my Audi A8 and now the lane departure warning system isn't working properly. How can I reset it to factory settings?

To reset the lane departure warning system, you can try disconnecting your car battery for a few minutes and then reconnecting it. This will often reset the system to the factory settings. If that doesn't work, you may need to take your car to a dealership to have them reset it for you.
