A/C COMPRESSOR, REMOVING AND INSTALLING, Vehicles with 3.0L, Diesel: Removing

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.

-- Turn off the ignition.

-- Discharge the refrigerant circuit. 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).

NOTE:

Depending on the allocation of the service connection to the refrigerant line and vehicle version, it may be necessary to remove the left additional reinforcement on the tower brace so that the service coupling of the A/C service station can be connected (for example, on the Audi Q5). Refer to OVERVIEW - SUSPENSION STRUT WITH MOUNTING BRACKET, SHOCK ABSORBER FORK, UPPER CONTROL ARM AND TOWER BRACE and 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 A/C Service Station).

CAUTION:

Risk of damaging refrigerant lines and hoses.

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

-- Remove the bolts -2- and -3- and remove the refrigerant lines from the A/C compressor. Refer to REFRIGERANT LINES, DISCONNECTING AND CONNECTING AT A/C COMPRESSOR (removing and installing the refrigerant lines to the A/C compressor)

NOTE:

Close open lines and connections on A/C compressor using suitable caps (to prevent possible penetration of dirt and moisture).

-- Remove the front noise insulation. Refer to FRONT NOISE INSULATION .

NOTE:

Depending on the vehicle version, it may be necessary to remove the bumper cover in order to remove the front noise insulation (for example, on the Audi A4 allroad). Refer to Front Bumper .

CAUTION:

Danger of destroying by reversed direction with a ribbed belt already running.

Before removing the ribbed belt, mark the running direction with chalk or a marker.

-- To remove the ribbed belt, swivel the tensioner using Torx Socket - T60 T40087 in the direction of -arrow-.

-- If equipped, loosen the power steering pump from the bracket (not always necessary on vehicles with a flexible pressure line to the power steering pump), move it to the side and then tie it to the engine with wire, for example. Refer to POWER STEERING PUMP, REMOVING AND INSTALLING, VEHICLES WITH DYNAMIC STEERING, Vehicles with 6-Cylinder Diesel Engine or POWER STEERING PUMP, REMOVING AND INSTALLING, VEHICLES WITHOUT DYNAMIC STEERING, Vehicles with 6-Cylinder Diesel Engine .

NOTE:

The pressure line to the power steering pump -C- is secured to the A/C compressor by the bracket with the mounting bolt. When removing the A/C compressor, make sure not to bend the pressure line to the power steering pump -C- than absolutely necessary (maximum 5 mm).

If it becomes necessary to remove the A/C compressor, do not bend the pressure line for the power steering pump -C- -A- more than 5 mm. Loosen the power steering pump with the bracket from the engine and pull it toward the front (refer to POWER STEERING PUMP, REMOVING AND INSTALLING, VEHICLES WITH DYNAMIC STEERING, Vehicles with 6-Cylinder Diesel Engine or POWER STEERING PUMP, REMOVING AND INSTALLING, VEHICLES WITHOUT DYNAMIC STEERING, Vehicles with 6-Cylinder Diesel Engine ), move it to the side and secure it on the engine using, for example, wire. When moving the power steering pump to the side, be sure not to bend, twist or pull the lines to the power steering pump.

There are different versions (stiff or flexible) of the power steering pump pressure line.

The pressure line and power steering pump are only installed on vehicles without electromechanical power steering. Refer to POWER STEERING PUMP, REMOVING AND INSTALLING, VEHICLES WITH DYNAMIC STEERING, Vehicles with 6-Cylinder Diesel Engine or POWER STEERING PUMP, REMOVING AND INSTALLING, VEHICLES WITHOUT DYNAMIC STEERING, Vehicles with 6-Cylinder Diesel Engine .

-- Remove the bolts -arrows- and remove the A/C compressor.
