How to change the cabin air filter on an Audi A6?

I noticed that the air flow from my Audi A6's vents has decreased and I suspect it's because the cabin air filter needs to be changed. Can someone guide me on how to do it myself?

To change the cabin air filter on your Audi A6, start by locating the filter housing, which is usually under the hood on the passenger side of the vehicle. Once you've located it, remove the retaining clips or screws and open the housing. Take out the old filter and replace it with a new one. Make sure to follow the arrow direction on the filter for proper installation.
