Capacities for Audi A3 (8P_) from 2004
WARNING: This page does not describe the selected car, but rather 17 other vehicles, including the 2009 Audi S4, 2009 Audi A4, 2008 Audi S4, 2008 Audi RS 4, and 2008 Audi A4. However, it is still accessible from the selected car via links, so may be relevant.
Characteristics of refrigerant circuit:
- Expansion valve
- Receiver
- Compressor from various manufacturers with A/C Compressor Regulator Valve N280 (without A/C clutch) → 87 - Air conditioning and → Electronic Parts Catalog ETKA.
| Vehicle model | Production period | Total quantity of oil in refrigerant circuit in cm 3 | Quantity of refrigerant oil in replacement compressor in cm 3 | Differing characteristics of this refrigerant circuit |
| Audi A3 | From 05.03 to 10.03 | 180 + / - 10 | 180 + / - 10 | Denso compressor of 7 SEU 16 type |
| 10.03 on | 120 + / - 10 | 120 + / - 10 | Zexel compressor | |
| 110 + / - 10 | 110 + / - 10 | Sanden compressor | ||
| 140 + / - 10 | 140 + / - 10 | Denso compressor of 7 SEU 17 type |
NOTE:
- The replacement compressor contains the full quantity of oil intended for the refrigerant circuit. On replacement, the quantity of oil in the compressor is therefore to be adjusted → Refrigerant Circuit Components, Replacing .
- Different compressors are installed depending on production period and engine.
- At the start of production, exclusive use was made of compressors of type "7 SEU 16" from "Denso" (e.g. compressor with part no. 1K0 820 803 up to index "D" ). In Model Year 2004 (as of approx. 10.03), a gradual change was made to a different type of "Denso" compressor ( "7 SEU 17" e.g. compressor with part no. 1K0 820 803 as of index "E" ).
- With effect from Model Year 2004 (as of approx. 10.03), "Zexel" (type "DSC17E" ) and "Sanden" (type "PXE16" ) compressors are also gradually being introduced depending on engine → Electronic Parts Catalog ETKA.
- This compressor is available as a replacement part with different oil capacities and attention must therefore be paid to oil quantity in compressor as well as exact part number → 87 - Air conditioning and → Electronic Parts Catalog ETKA.
- The reason for the different oil quantities in the compressor for an otherwise identical refrigerant circuit is the design of the actual compressor. Attention is to be paid to these oil quantities. Too much oil in the circuit results in higher pressures and reduced system cooling output; insufficient oil can cause lubrication problems in the compressor.
- The compressor may have been installed at the factory with a rating plate indicating the part number and the quantity of refrigerant oil in the compressor.
