How often should I change the air filters in my Audi A2?

I recently purchased an Audi A2 and I want to make sure I am properly maintaining it. How often should I change the air filters and what type of air filters should I use?

As a general rule, it is recommended to change your air filters every 15,000 miles or every year, whichever comes first. However, if you live in a dusty or polluted area, it may be necessary to change them more frequently. As for the type of air filters, it is best to use high-quality, OEM (original equipment manufacturer) filters for the best performance and longevity.
