Capacities For AUDI TT (FV_) From My 2015

WARNING: This page does not describe the selected car, but rather 9 other vehicles, including the 2015 Audi S7, 2015 Audi RS 7, 2015 Audi A7 Quattro, 2014 Audi S7, and 2014 Audi RS 7. However, it is still accessible from the selected car via links, so may be relevant.

Features of the refrigerant system:

Expansion Valve
Receiver/Dryer
Mechanically driven "Denso" or "Sanden" A/C compressor with A/C Compressor Regulator Valve -N280-. Refer to [For engine(s) CTUA, CEUC, CRDB, CGXB, CPNB] System Overview - Refrigerant Circuit (vehicle-specific repair information) .

NOTE: Depending on time period of production and depending on engine, different mechanically driven A/C compressors are installed (these A/C compressors do not have an A/C clutch). Refer to [For engine(s) CTUA, CEUC, CRDB, CGXB, CPNB] System Overview - Refrigerant Circuit (vehicle-specific repair information).

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 10/2014	110 ⁺ / _- 10	110 ⁺ / _- 10	"Denso" A/C compressor
-	-	75⁺ / _- 10	75 ⁺ / _- 10	"Sanden" A/C compressor
-	-	110 ⁺ / _- 10	110 ⁺ / _- 10	"Delphi" A/C compressor

NOTE:

The replacement 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 .

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

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 [For engine(s) CTUA, CEUC, CRDB, CGXB, CPNB] System Overview - Refrigerant Circuit (vehicle-specific repair information).

The reason for the different oil capacities inside the A/C compressor is due to the design of the A/C compressor 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.
