Note| t | At the start of production, all vehicles except the Audi A6 hybrid were fitted with mechanically driven air conditioner compressors manufactured by „Denso“. Air conditioner compressors produced by other manufacturers may also be fitted at a later date → Electronic parts catalogue and → Air conditioning; Rep. gr.87 (vehicle-specific Workshop Manual). |
| t | At the start of production, the Audi A6 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 | At the start of production, the Audi A6 hybrid was fitted with an air conditioner compressor with a refrigerant oil quantity of 200 ccm. A capacity of 840 +/- 15 g for refrigerant was planned at the factory for these vehicles (specification on label for refrigerant). Shortly after the start of production, the refrigerant oil quantity was reduced to 160 ccm and the refrigerant quantity was raised to 860 +/- 15 g. In after-sales service, a quantity of 860 +/- 15 g of refrigerant always applies for these vehicles irrespective of the refrigerant oil quantity (if necessary, change capacity specification on label with a water-proof pen). |
