How to change the cabin air filter in an Audi A5?

I noticed a strange smell coming from my car's air vents and suspect it may be due to a dirty cabin air filter. How can I change it myself?

To change the cabin air filter in an Audi A5, start by locating the filter housing under the dashboard on the passenger side. Remove the panel covering the filter housing and take out the old filter. Make sure to clean out any debris or dust that may have accumulated in the housing before inserting the new filter. Finally, secure the panel back in place and you're good to go!
