How do I change the cabin air filter in an Audi 80?

I recently purchased an Audi 80 and noticed that the air blowing from the vents smells musty. I suspect it's time to change the cabin air filter, but I'm not sure how to do it myself. Can someone provide steps to change the cabin air filter in an Audi 80?

To change the cabin air filter in an Audi, you will first need to locate the filter housing under the dashboard on the passenger side. It is usually secured by clips or screws. Once you have access, simply remove the old filter and replace it with a new one. Make sure to follow the instructions in your car's manual for specific details.
