Capacities For AUDI TT (8J_) From My 2007

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.

Vehicle type	Production period	Total quantity of oil in refrigerant circuit in cm³	Quantity of refrigerant oil in replacement compressor in cm³	Differing features of this refrigerant circuit
Audi TT	From 08/2006	90 ⁺ / _- 10	90 ⁺ / _- 10	"Denso" A/C compressor "6 SEU 14"
		110 ⁺ / _- 10	110 ⁺ / _- 10	"Sanden" A/C compressor
		110 ⁺ / _- 10	110 ⁺ / _- 10	"Delphi/Mahle" A/C compressor

NOTE:

The replacement A/C 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 .

At the start of production, "Denso" A/C compressors "6 SEU 14" were installed; these A/C compressor do not have an A/C clutch (driven by the engine). A/C compressors from other manufacturers may also be installed at a later time, depending on the engine. Refer to the Parts Information and Refrigerant Circuit (vehicle-specific service information).

From MY 2008, "Sanden" A/C compressors (type "PXE16") are also installed as a running change on certain engines; they do not have an A/C clutch (it is driven continuously by the engine). Refer to the Parts Information and Refrigerant Circuit (vehicle-specific service information).

With a gradual introduction starting from MY 2011 and depending on the engine, "Delphi/Mahle" A/C compressors are also installed. Refer to the Parts Information and Refrigerant Circuit (vehicle-specific service information).

This A/C compressor is available as a replacement part with different oil capacities, therefore note the oil capacity in the A/C compressor and the exact part number. Refer to the 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.
