Cabin Air Filter Replacement

Model: Audi A4 B6 - Years 2000-2004
Part: Cabin air filter

The cabin air filter is located in the engine compartment, just below the windshield on the passenger side; open the hood and remove the seal along the rear edge, take off the plastic cover under the windshield, and access the cabin air filter housing; then remove the cover and pull out the old filter, ensuring there are no dirt residues inside the filter box, and insert the new one following the airflow direction; reassemble the cover, the plastic panel, and the seal. When replacing the cabin air filter, it is also recommended to sanitize the cabin with a suitable antibacterial spray.
