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.

Installation is carried out in the reverse order while observing the following.

NOTE:

Follow the instructions for installing the O-rings. Refer to REFRIGERANT CIRCUIT SEALS .

Following attachment, check routing of refrigerant lines. They must be inserted in holders provided and not make contact with other components.

-- Replace the O-ring seals -4-. Allocate correct version.

-- Clean the refrigerant line connections -3 and 5- and inspect them for damage.

-- Make sure the O-rings -4- sit correctly inside the grooves of the respective mount.

-- Check the alignment pin -2- (not present on all connections) for damage and make sure that it is seated correctly.

-- Tighten the bolts -1-.

-- Install the remaining removed components.

-- Evacuate the refrigerant circuit and fill it. Refer to USING SERVICE STATION . For additional information, refer to OVERVIEW - REFRIGERANT CIRCUIT, NOT OPENING THE REFRIGERANT CIRCUIT, VEHICLES WITHOUT HIGH VOLTAGE SYSTEM and OVERVIEW - REFRIGERANT CIRCUIT, OPENING THE REFRIGERANT CIRCUIT, VEHICLES WITHOUT HIGH VOLTAGE SYSTEM (Refrigerant R134a, Servicing; Refrigerant Circuit, Using Service Station).

-- Electrical connections and routing. Refer to the appropriate SYSTEM WIRING DIAGRAM.

-- Energize the power supply to the high voltage system. Refer to HIGH VOLTAGE SYSTEM, RE-ENERGIZING .

Restart the high voltage system

CAUTION:

Risk of electrocution

Death or serious bodily injury by electric shock

The high voltage system may only be restarted by qualified personal (Audi high voltage technicians).
Make sure the vehicle is energized using the "Guided Fault Finding" on the Vehicle Diagnostic Tester.
The qualified personal (Audi high voltage technician) restarts the vehicle.
The Audi high voltage technician should put a sign on the vehicle to identify it as a high voltage vehicle.

NOTE:

Restart the high voltage system:

Connect the vehicle diagnostic tester.

Select the Guided Fault Finding mode.
