How can I change the headlight bulbs on my Audi A6?

I've noticed that one of my headlight bulbs is out on my Audi A6 and I want to replace it myself. Can someone walk me through the steps to change the bulb?

First, make sure you have the correct replacement bulb for your Audi A6. Then, locate the back of the headlight assembly and remove the cover. You should be able to twist and pull out the old bulb, then insert and secure the new one. Finally, replace the cover and test to make sure the new bulb is working properly.
