How do I change the cabin air filter on an Audi A5?

I've noticed that the air in my Audi A5 is getting stuffy and I think it might be time to change the cabin air filter. Can anyone walk me through the process of doing this myself?

First, locate the cabin air filter housing under the dashboard on the passenger side. Pop it open and remove the old filter. Be sure to use a filter that meets Audi's specifications for proper air flow and filtration.

I recommend changing the cabin air filter every 15,000-20,000 miles to ensure fresh air and optimal air flow. It's an easy task and only takes a few minutes to do yourself.
