Capacities for Audi A4 (8E_) from 2001, Audi A4 Cabriolet (8H_) from 2003
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:
- Restrictor
- Reservoir
- "Denso" compressor 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 A4 Audi RS4 | From 11.00 to 01.04 All | 180 + / - 10 | 180 + / - 10 | Compressor type 6 SEU 12 6 SEU 14 7 SEU 16 or 7 SEU 17 (refer to notes below) |
| 01.04 on All except 8-cyl. engine | 120 + / - 10 | 120 + / - 10 | Compressor type 6 SEU 14 or 7 SEU 17 (refer to notes below) | |
| 01.04 on 8-cyl. engine only | 130 + / - 10 | 130 + / - 10 | Compressor type 7 SEU 17 (refer to notes below) |
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 .
- The Audi A4 is equipped with different compressors depending on the engine and production period As replacement compressors of this type are supplied with different oil capacities, the exact part no. must be noted → 87 - Air conditioning and → Electronic Parts Catalog ETKA.
- At the start of production, the compressor types in the first line of the table were supplied with a refrigerant oil quantity of 180 cm 3 . These compressors can be recognized from the index of the part number (8E0 260 805 with one index or with double index up to "AH" ). In Model Year 2004 (as of approx. 01.04), a gradual change was made to other types of compressor with a refrigerant oil quantity of 120 cm 3 or 130 cm 3 . These compressors can be recognized from the index of the part number 8E0 260 805 (with double index as of " AJ" ) or 4F0 260 805 (and index "E" for vehicles with 8-cyl. engine) → 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.
