The following 3 illustrations show the layout and the version of the components of the extraction outlets on the Audi A3; the layout and the components on the Audi A3 Sportback and on the Audi A3 Cabrio have some slight differences (the function however is the same).

-- Check ventilation channels to both ventilation frames -A- in luggage compartment (left and right) for throughput.

Sealing lips -B- in ventilation frames -A- must move freely and close by themselves.
Blocked channels to ventilation frames or jammed sealing lips may cause windows to fog up.

NOTE:

In this illustration, ventilation frame -A- is depicted with rear bumper removed.

For forced air extraction, one ventilation frame -A- each is installed on left and right.
So that sealing lips -B- close correctly, ventilation frame -A- must be installed on proper side (smaller radius -C- at top).
In order for the passenger compartment ventilation to function properly, the vent openings -A- and -B- in the luggage compartment trim on left and right must not be closed.
