| Characteristics of refrigerant circuit: |
| l | Restrictor (red-coloured). |
| l | Reservoir |
| l | „Denso“ air conditioner compressor with air conditioner compressor regulating valve -N280- (no magnetic clutch) |
| Vehicle model | Production period | Capacity in grammes | Differing characteristics of this refrigerant circuit | ||||
| Audi A6/S6 | From 04.04 onwards | 530 + / - 20 |

Note| t | Replacement restrictors with different holes are available (yellow-coloured 1.54 mm, red-coloured 1.42 mm). |
| t | Depending on manufacturer, colour of red restrictor may tend more towards orange. |
| t | To avoid altering the cooling output of the air conditioner, only red-coloured restrictors are to be fitted. |
| t | Different air conditioner compressors are fitted depending on the model → Air conditioning; Rep. gr.87 (vehicle-specific workshop manual) and → Electronic parts catalogue. |
| t | The condenser fitted on vehicles with a 10-cyl. TFSI engine (Audi RS 6) has a smaller internal volume than the condenser with other engines. For vehicles with a 10-cyl. TFSI engine the refrigerant capacity is thus also slightly less than for other vehicles → Electronic parts catalogue. |
