Capacities For AUDI TT (8J_) From My 2007

WARNING: This page does not describe the selected car, but rather 9 other vehicles, including the 2018 Audi S6, 2018 Audi A6 Quattro, 2018 Audi A6, 2017 Audi S6, and 2017 Audi A6 Quattro. However, it is still accessible from the selected car via links, so may be relevant.

Features of the refrigerant system:

Expansion Valve
Receiver/Dryer
Compressors from various manufacturers with an A/C Compressor Regulator Valve -N280- (without a solenoid coupling). Refer to REFRIGERANT CIRCUIT [For engine(s) CTUA, CAED, CREH, CEUC, CTGE, CREC, CYNB, CPNB]

Vehicle model	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" A/C compressor

NOTE:

The replacement A/C compressor contains the full quantity of oil intended for the refrigerant circuit. On A/C compressor replacement, the quantity of oil in the A/C compressor is therefore to be adjusted. 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). Compressors from other manufacturers may also be installed at a later time, depending on the engine. Refer to the parts information and REFRIGERANT CIRCUIT [For engine(s) CTUA, CAED, CREH, CEUC, CTGE, CREC, CYNB, CPNB]

As of MY 2008, on certain engines, "Sanden" A/C compressors (type "PXE16") were installed; they do not have an A/C clutch (it is driven by the engine). Refer to the parts information and REFRIGERANT CIRCUIT [For engine(s) CTUA, CAED, CREH, CEUC, CTGE, CREC, CYNB, CPNB]

With a gradual introduction starting from MY 2011 and depending on the engine, "Delphi" A/C compressors are installed. Refer to the parts information and REFRIGERANT CIRCUIT [For engine(s) CTUA, CAED, CREH, CEUC, CTGE, CREC, CYNB, CPNB]

This A/C compressor is available as replacement parts with different oil fill capacities, therefore note the capacity on the A/C compressor and the exact part number. Refer to the REFRIGERANT CIRCUIT [For engine(s) CTUA, CAED, CREH, CEUC, CTGE, CREC, CYNB, CPNB] (vehicle-specific repair 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 with 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 performance 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.
