Note| t | The replacement compressor contains the full quantity of oil intended for the refrigerant circuit. On replacement, the quantity of oil in the air conditioner compressor is therefore to be adjusted → Chapter. |
| t | The Audi A4 is fitted with different air conditioner compressors depending on the engine and production period. As replacement air conditioner compressors of this type are supplied with different oil capacities, the exact part no. must be heeded → Air conditioning; Rep. gr.87 (vehicle-specific workshop manual) and → Electronic parts catalogue. |
| t | 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 air conditioner compressors can be recognised 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 air conditioner compressors can be recognised 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 catalogue. |
| t | The different oil quantities in the air conditioner compressor may result from the design of the air conditioner compressor (with or without oil separator at high-pressure connection) or, in the case of identical air conditioner compressors, from the design of the refrigerant circuit. Attention is to be paid to these oil quantities. Too much oil in the circuit results in higher pressures and a reduced cooling output of the system. Too little oil may lead to lubrication problems in the air conditioner compressor. |
| t | The air conditioner compressor may have been fitted at the factory with a rating plate indicating the part number and the quantity of refrigerant oil in the air conditioner compressor. |
