How can I change the air filters on an Audi A6?

I've noticed that the air in my Audi A6's cabin is not as fresh as it used to be. How can I change the air filters to improve the air quality?

To change the air filters on your Audi A6, you will need to locate them under the hood of your car. The filters are typically located near the firewall on the passenger side. Once located, you can easily remove and replace them with new ones, making sure to align the arrows on the filters with the direction of the airflow.
