How do I change the cabin air filter in an Audi A2?

I've been experiencing some strange odors while driving my Audi A2 and was wondering if it could be because of a dirty cabin air filter. How can I change it myself? Is it something I should be doing regularly?

Yes, it is important to change your cabin air filter regularly to maintain a fresh and clean air inside your Audi A2. It is recommended to change it every 15,000 miles or once a year, whichever comes first.
