How do I change my Audi's air filter?

I recently noticed that my Audi's engine has been running less smoothly and the air conditioning isn't as cold as it used to be. I suspect it's time to change the air filter, but I'm not sure how to do it. Can someone walk me through the steps?

You're right, it's likely time to change your air filter. First, locate the air filter housing under the hood of your Audi. It's usually a black plastic box with a metal clip holding it closed. Unclip the box and remove the old filter. Make sure to check for any debris or buildup in the housing before replacing the filter. Then, insert the new filter and reattach the housing. Your engine and air conditioning should run much smoother now.
