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.

De-energize the high voltage system to perform the necessary work on the high voltage system for the following procedure. Refer to HIGH VOLTAGE SYSTEM, DE-ENERGIZING and "read and follow the high voltage electrical system general warnings" in HIGH VOLTAGE SYSTEM GENERAL WARNINGS .

-- Turn off the ignition.

-- De-energize the high voltage system. Refer to HIGH VOLTAGE SYSTEM, DE-ENERGIZING .

High Voltage System,

CAUTION:

Risk of electrocution

Death or serious bodily injury by electric shock.

The high voltage system may only be activated by qualified personnel (Audi high voltage mechanic).
Make sure that the high voltage system is completely disabled. Make sure the vehicle is de-energized using "Guided Fault Finding" on the Vehicle Diagnostic Tester.
The qualified personal (Audi high voltage technician) determines the voltage and secures the system from restarting using the Service Disconnect Lock T40262. Keep the ignition key and the High Voltage System Maintenance Connector -TW- safely with the qualified personal to secure the system from restarting.
The Audi high voltage technician should put a sign on the vehicle to identify it as a high voltage vehicle.

NOTE:

Disable the high voltage system:

Connect the vehicle diagnostic tester.

Select the Guided Fault Finding mode.

Using the GO TO button, select the following menu commands

CAUTION:

There is a risk of damaging the cable or the connector for the high voltage system

Do not bend or twist the connector for the high voltage system -B-.
Do not twist, stretch, kink, or bend the cable for the high voltage system -C-.

-- Secure the A/C compressor to the vehicle (for example, with a wire) without pulling or bending the high voltage system cable or the coolant hoses.

CAUTION:

There is a risk of damaging the high voltage system cable or the refrigerant lines and hoses.

Do not stretch, kink or bend refrigerant lines and hoses.

NOTE:

If the A/C compressor cannot be swiveled away enough from the engine, then the A/C compressor must be removed. Refer to A/C COMPRESSOR, REMOVING AND INSTALLING, ELECTRICALLY-DRIVEN A/C COMPRESSOR .
