Cabin Air Filter - Repair or Replace
If the air coming out of your vents smells a little funny—like mildew or funk—or if your windshield fogs up with the A/C on, your 2000 Audi A4 may have a clogged cabin filter. Many manufacturers recommend replacing the cabin filter, or pollen filter, as part of its scheduled maintenance.
