WARNING: This page does not describe the selected car, but rather 13 other vehicles, including the 2017 Audi SQ5, 2017 Audi Q5, 2016 Audi SQ5, 2016 Audi Q5, and 2015 Audi SQ5. However, it is still accessible from the selected car via links, so may be relevant.

WARNING:

Warning information for the high voltage system:

Procedures near high voltage components. Refer to PROCEDURES NEAR HIGH VOLTAGE COMPONENTS .

Procedures for which the ignition needs to be switched off. Refer to PROCEDURES FOR WHICH THE IGNITION NEEDS TO BE SWITCHED OFF .

NOTE:

Deposits in the plenum chamber (Leaves, tree needles, etc...) can negatively affect water drain. This can raise the water level (for example, at the car wash or during heavy precipitation) and water can seep into the vehicle interior via the grommets and the fresh air intake shaft.

NOTE:

Cleaning is charged separately.

-- Remove rough contaminates in the plenum chamber and from the water drain grommets -A- and from the water drain -C- with a commercially available flexible gripping tool.
