Capacities, AUDI A1 (8X_) From My 11
Features of the refrigerant system:
- Expansion Valve
- Fluid Reservoir
- Compressors from various manufacturers with an A/C compressor regulator valve -N280- (without an A/C clutch). Refer to [For engine(s) BPY, CETA, CCTA, CDMA, CEPB] Description and Operation .
| 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 A1 | As of 08.10 | 110 + / - 10 | 110 + / - 10 |
|
| 90 + / - 10 | 90 + / - 10 | Denso A/C compressor |
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 REMOVAL AND INSTALLATION .
Different A/C compressors are installed depending on production period and engine.
At Start Of Production, A/C compressors manufactured by Denso type 6 SEU 14C or Sanden type 7 PXE 16 were installed. Refer to [For engine(s) BPY, CETA, CCTA, CDMA, CEPB] Removal and Installation .
Depending on the engine, an A/C compressor manufactured by Delphi type 6 CVC 140 will be installed at a later point in time (introduction still open). Refer to [For engine(s) BPY, CETA, CCTA, CDMA, CEPB] Removal and Installation .
These A/C compressors are available as replacement parts with different oil fill capacities, therefore note capacity on the A/C compressor and the exact part number. Refer to the [For engine(s) BPY, CETA, CCTA, CDMA, CEPB] Specifications .
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.
