Overview - Air Routing And Air Distribution In Passenger Compartment

WARNING: This page does not describe the selected car, but rather 23 other vehicles, including the 2017 Audi S5, 2017 Audi A5 Quattro, 2016 Audi S5, 2016 Audi A5 Quattro, and 2015 Audi S5. However, it is still accessible from the selected car via links, so may be relevant.
NOTE:

Refer to AIR INTAKE AND OUTLET OPENINGS 

For component locations of individual components. Refer to OVERVIEW - COMPONENTS INSIDE FRONT PASSENGER COMPARTMENT and ACTUATORS .

The passenger compartment ventilation occurs via two vent frames (in luggage compartment at the right and left near the bumper). Refer to PASSENGER COMPARTMENT FORCED AIR EXTRACTION, CHECKING  (passenger compartment forced air extraction).

The air routing and the air distribution in the passenger compartment is different on vehicle equipped with the "Convenience" A/C system and the "Basis" A/C system.

From 01/2008, A/C units which have an additional connection for the glove compartment cooling are being installed as a running change. On vehicles without glove compartment cooling, this connection is sealed with a plug. Refer to GLOVE COMPARTMENT COOLING CONNECTION ON AIR INTAKE HOUSING .

The following illustrations show the location of the components on an Audi A5 Coupe; an Audi A5 Sportback, Audi A4, Audi Q5, etc. The location of the components varies slightly. The description of the components is not different; removing and installing is performed in the same way as on the Audi A5 Coupe.
