How can I adjust the air suspension on my Audi A6?

I recently purchased an Audi A6 and noticed that the air suspension seems to be uneven. How can I adjust it to fix this issue?

To adjust the air suspension, first locate the control module under the car's rear parcel shelf. Remove the cover and you will see a yellow adjustment screw. Turning this screw clockwise will raise the suspension while turning it counterclockwise will lower it. Be sure to make small adjustments until you achieve the desired height.
