Capacities For AUDI A1 (8X_) From My 2011

WARNING: This page is about a different car, the 2023 Audi SQ8, 2023 Audi RS Q8, and 2023 Audi Q8. However, it is still accessible from the selected car via links, so may be relevant.

Features of the refrigerant system:

Expansion Valve
Receiver/Dryer
A/C compressor by various manufacturers with A/C Compressor Regulator Valve -N280- (without A/C clutch). Refer to Refrigerant Circuit (vehicle-specific service information) and the Parts Information.

		75⁺ / _- 10	75⁺ / _- 10	"Sanden" A/C compressor, part number "5K0 xxx xxx"
	From 07/2012	75⁺ / _- 10	75⁺ / _- 10	"Sanden" A/C compressor, "5Q0 xxx xxx"
		110 ⁺ / _- 10	110 ⁺ / _- 10	"Delphi/Mahle" A/C compressor, part number "5K0 xxx xxx" or "5Q0 xxx xxx"

NOTE:

The replacement compressor contains the full quantity of oil intended for the refrigerant circuit. If the A/C compressor is being replaced, the quantity of oil in the A/C compressor must be adjusted. Refer to Refer to REFRIGERANT CIRCUIT COMPONENTS, REPLACING .

Different A/C compressors are installed depending on production period and engine.

At the start of production, A/C compressors manufactured by "Denso" type "6 SEU 14C" or "Sanden" type "7 PXE 16/14" were installed. Refer to the Parts Information and Refrigerant Circuit (vehicle-specific service information).

Depending on the engine, A/C compressors from manufacturers "Sanden" type "11 PXC 14" or "Delphi/Mahle" type "6 CVC 140" may also be installed at a later time (introduction TBD, planned from 09/2012). Refer to the Parts Information and Refrigerant Circuit (vehicle-specific service information).

Depending on the engine, a different version of "Denso" or "Sanden" A/C compressors may be installed at a later date (introduction not yet finalized). Refer to the Parts Information.

These A/C compressors are available as replacement parts with different oil capacities, therefore note the oil capacity in the A/C compressor and the exact part number. Refer to Refrigerant Circuit (vehicle-specific service information) and the Parts Information.

The reason for the different oil capacities inside the A/C compressor is due to the design of the A/C compressor (with or without an oil separator on the high pressure connection) or to the design of the refrigerant circuit if the A/C compressors are have the identical design. Pay attention to the different capacities. Too much oil in the circuit leads to higher pressures and reduces cooling output of the system. Too little oil may lead to lubrication problems in the compressor.

A data plate may be attached to the A/C compressor by the manufacturer, indicating the part number and refrigerant oil quantity.

From 11/2012, the refrigerant oil quantity for the "Denso" A/C compressor with the part number "5Q0 xxx xxx" was gradually increased from 80 ccm to 110 ccm. The increased refrigerant oil capacity applies retroactively to all vehicles with this A/C compressor. On vehicles that were built through 11/2012 with this A/C compressor, check whether the refrigerant oil capacity was already topped up during a previous workshop visit. If not, fill the refrigerant circuit with an additional 30 ccm of refrigerant oil. Then note the refrigerant oil capacity with a waterproof marker on the sticker and fill the refrigerant circuit with the above-specified refrigerant quantity.
