| Characteristics of refrigerant circuit: |
| l | Restrictor |
| l | Reservoir |
| l | „Denso“ air conditioner compressor with air conditioner compressor regulating valve -N280- → Air conditioning; Rep. gr.87 (vehicle-specific workshop manual) and → Electronic parts catalogue |
| Vehicle model | Production period | Total quantity of oil in refrigerant circuit in cm3 | Quantity of refrigerant oil in replacement compressor in cm3 | ||
| Audi A6/S6 | From 04.04 onwards | 130 + / - 10 | 130 + / - 10 | ||
| Audi RS 6 | From 05.08 onwards | 130 + / - 10 | Depending on the version of the air conditioner compressor (refer to note below)
|
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. |
| t | The Audi A6 is fitted with different air conditioner compressors depending on the engine and production period. |
| t | As there are different versions of this type of replacement air conditioner compressor, the exact part no. must be heeded → Air conditioning; Rep. gr.87 (vehicle-specific workshop manual) and → Electronic parts catalogue. |
| 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. |
| t | On account of the different test bench procedure for this engine, the 10-cyl. TFSI engine (Audi RS 6) is fitted at the factory with an air conditioner compressor with a smaller quantity of refrigeration oil (70 + / - 10 cm3) than for the 10-cyl. FSI engine (Audi S6) and the other engines (130 + / - 10 cm3) (at present, the air conditioner compressors on the 10-cyl. FSI and the 10-cyl. TFSI only differ in terms of the part number and the quantity of refrigeration oil; refer also to the air conditioner compressor rating plate). To adjust the total quantity of oil in the refrigerant circuit at the factory, the missing amount of oil in the air conditioner compressor (60 + / - 10 cm3) with the 10-cyl. TFSI engine (Audi RS 6) is added at a different point in the refrigerant circuit. This is not necessary when performing service work, as replacement air conditioner compressors are only supplied with the original quantity of oil (130 + / - 10 cm3) (would only be required as part of service work if a new air conditioner compressor with the smaller quantity of oil were to be installed) → Electronic parts catalogue. |
