This video guide explains how to change the air cabin filter, also called dust pollen filter on an Audi 80.
This filter is very important in order to have a clean air inside our car.
It is neccesary to change it each 15.000 Km or at least once a year. Personally I do this maintenance at the beginning of the spring. This maintenance operation is easy to do, and the parts are sold in a lot of shops.
