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 air conditioner compressors fitted at the start of production are manufactured by „Denso“ (type „6 SEU 14“) for vehicles with 4 and 6-cyl. engine and type „7 SEU 17“ for vehicles with 8-cyl. engine); this air conditioner compressor has no magnetic clutch (it is constantly driven by the engine). Different makes of air conditioner compressor may also be fitted at a later date depending on the engine → Electronic parts catalogue and → Air conditioning; Rep. gr.87 (vehicle-specific workshop manual). |
| t | At the start of production, the Audi Q5 hybrid is fitted with an electrically driven „Denso“ air conditioner compressor (electrical air conditioner compressor -V470- with control unit for air conditioning compressor -J842-). There is no provision for an air conditioner compressor regulating valve -N280- on this air conditioner compressor. |
| t | As of Model Year 2012, air conditioner compressors with an air conditioning system magnetic clutch -N25- fitted at the pulley are additionally to be introduced for certain engines and models → Air conditioning; Rep. gr.87 (vehicle-specific workshop manual) and → Electronic parts catalogue. |
| t | This air conditioner compressor is available as a replacement part with different oil capacities and attention must therefore be paid to the oil quantity in the air conditioner compressor as well as to the exact part number → Air conditioning; Rep. gr.87 (vehicle-specific workshop manual) and → Electronic parts catalogue. |
| t | At the start of production, the Audi Q5 hybrid was fitted with an air conditioner compressor with a refrigerant oil quantity of 160 ccm. Shortly after the start of production, the refrigerant oil quantity was increased to 200 ccm. The refrigerant oil does not have to be topped up on vehicles fitted with an air conditioner compressor with a refrigerant oil quantity of 160 ccm. However, if the refrigerant circuit has been flushed for example, a total of 200 ccm should also be filled in in this vehicle as the specified refrigerant oil quantity. The correct amount of refrigerant oil will already be filled into a replacement air conditioner compressor → 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. |
