Audi A4 Cabin Filter Replacement

All the air that enters your car, when the windows are up, comes through the cabin filter (a.k.a. dust and pollen filter). A lot of air goes through the filter each day for months and even years at a time. Although the cabin filter does its best to filter out pollen, dirt, debris, bits of trees, and rodents, it eventually gets clogged. Although the recommended change interval is 12K -15K or 1 year on most Audi and Volkswagen models, many enthusiasts recommend replacing the filter twice a year, during the Spring and Fall seasons. It’s a 5 minute job and does not require any tools! What could be easier?
