Overview - Air Guide

WARNING: This page does not describe the selected car, but rather 18 other vehicles, including the 2016 Audi S4, 2016 Audi A4 Quattro, 2016 Audi A4, 2015 Audi S4, and 2015 Audi A4 Quattro. However, it is still accessible from the selected car via links, so may be relevant.

Observe all of the additional warnings for all work performed on vehicles with the high voltage system. Refer to HIGH VOLTAGE VEHICLES SAFETY PRECAUTIONS and HIGH VOLTAGE SYSTEM GENERAL WARNINGS for Hybrid .

If it is necessary for the following procedure to perform work near high voltage components, "perform a visual inspection of the high voltage components and cables for damages" (refer to PERFORMING A VISUAL INSPECTION OF DAMAGE TO HIGH VOLTAGE COMPONENTS AND CABLES ) and "always follow the warnings when working on the high voltage system". Refer to HIGH VOLTAGE SYSTEM GENERAL WARNINGS for Hybrid .

WARNING:

Risk of unintended engine start

The ignition must be turned off and the ignition key must remain outside of the vehicle when working on vehicles with a high voltage system.

WARNING:

Handling high voltage cables:

Do not stand on or place tools on high voltage cables and their components as it may damage the cable insulation.
Never bend or kink high voltage cables forcefully as it may damage the cable insulation.
The round high voltage connectors are color coded with an external color ring and are mechanically coded using the guide- or code tabs. Always make certain that the coding matches when connecting the round connector in order to avoid any mechanical damage the high voltage connector.

CAUTION:

There is a risk of electrocution from damaged high voltage components.

Observe the following when working around high voltage components and high voltage wires:

Never work around high voltage components and cables with cutting, deformed, or sharp edged tools, or heat sources such as welding or soldering tools, heated air, and thermal glue.
Inspect the high voltage components visually before beginning.
Perform a visual inspection of the Electric Drive Power and Control Electronics -JX1-, the Electro-Drive Drive Motor -V141-, the Electrical A/C Compressor -V470- and the high voltage lines when working in the engine compartment.
Perform a visual inspection of the high voltage lines and covers when working on the underbody.
Perform a visual inspection of the high voltage lines and the Electrobox with the High Voltage System Maintenance Connector -TW- when working in the luggage compartment.
Perform a visual inspection on all of the potential equalization cables.

Observe the following items when performing the visual inspection:

The components do not display any signs of external damage.
The high voltage cable insulation and the potential equalization cables are not damaged.
The high voltage cables do not display any abnormal deformations.
Every high voltage component is marked with a red warning label.

Additional work

-- Turn off the ignition.

-- Remove the luggage compartment floor (different versions). Refer to OVERVIEW - LUGGAGE COMPARTMENT FLOOR .

Perform a visual inspection of the high voltage components and cables after removing the luggage compartment floor and "Read and follow the High Voltage Electrical System General Warnings". Refer to HIGH VOLTAGE SYSTEM GENERAL WARNINGS for Hybrid .
When working near the high voltage components and cables, make sure that they are not damaged.
Perform a visual inspection of the high voltage components and cables after finishing work on and before installing the luggage compartment floor panel.
