A/C COMPRESSOR, REMOVING AND INSTALLING ON BRACKET, MECHANICALLY-DRIVEN A/C COMPRESSOR, Vehicles with 4-Cylinder Engine: Notes

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.

NOTE:

At the start of production, only A/C compressors manufactured by "Denso" of type "6 SEU 14" are installed on vehicles with a 4- and 6-Cylinder engine. Depending on engine and period of production, A/C compressors from other manufacturers or another version may be installed at a later time.

It is possible to remove and re-install the A/C compressor at the bracket on vehicles with a 4-Cylinder engine and 6-Cylinder TDI engine without having to open the refrigerant lines.

On vehicles with a 6-Cylinder gasoline engine or an 8-Cylinder, the A/C compressor can be removed and installed from the bracket only when the refrigerant circuit is open. Refer to A/C COMPRESSOR, REMOVING AND INSTALLING and A/C COMPRESSOR, REMOVING AND INSTALLING .

On vehicles with an 8-Cylinder FSI engine, the A/C compressor is driven by an input shaft, which can be removed and replaced only if the A/C compressor has been removed. Refer to OVERVIEW - A/C COMPRESSOR POWER UNIT .

The following describes the removal and installation of the A/C compressor for a vehicle with a 4-Cylinder TDI engine and a 6-Cylinder TDI engine with a "Denso" A/C compressor type "6 SEU 14". For vehicles with 4-Cylinder engine or another A/C compressor, there may be differences (depending on engine, certain additional auxiliary components may need to be removed or loosened).

Do not discharge the refrigerant circuit to remove the bracket, do not remove refrigerant hoses and lines from A/C compressor.

Do not unfasten refrigerant lines and corresponding clamps.

After removing the A/C compressor, tie it to the vehicle with wire. Do not let is hang by the refrigerant lines.

Before removing, mark direction of operation of ribbed belt with chalk or felt-tipped pen. Running a used belt in the opposite direction could destroy it.

Different A/C compressors may be installed depending on engine and country variant.
