Replacing the Cabin Air Filter on an Audi A3 MK4

Model: Audi A3 8Y, MK 4 - Years 2020-2026
Part: Cabin air filter

On the intake of the ventilation system of the Audi A3 MK4, there is a filter that prevents dust and dirt from circulating, ensuring its efficiency. Periodically, we must replace the filter element. To do this, sit in the passenger seat, open the glove compartment in front of you, and below the multimedia reader, you will find a small cover in the trim. Remove this to access the filter box cover. By acting on the tabs at the edges, open the cover, remove the old filter, take the new one, spray some sanitising spray, and insert it into its housing. Close the cover, the trim cover, and the glove compartment.
