How do I change the air filter in an Audi A6?

I have noticed that the air in my car is no longer as fresh as it used to be. I suspect that it's time to change the air filter. How can I do this in an Audi A6?

To change the air filter in an Audi A6, you will need to locate the air filter housing. This is usually located in the engine bay. Once you have found it, remove the clips or screws that hold the housing in place. Then, carefully remove the old air filter and replace it with a new one. Make sure to put the housing back in place and secure it properly.
