Is it necessary to regularly change the air filter in my Audi A3?

I have been hearing mixed opinions on whether it is necessary to regularly change the air filter in my Audi A3. Some say it is only necessary after a certain amount of mileage, while others recommend changing it every year. What is the best practice and how often should I change it?

Yes, it is important to regularly change the air filter in your Audi A3. It is recommended to do so every 12,000 miles or once a year, whichever comes first.

Not changing your air filter can lead to a decrease in engine performance and even cause damage. It's best to err on the side of caution and change it every 12,000 miles or once a year.
