Capacities For AUDI A6 (4F_) From My 2005

WARNING: This page is about a different car, the 2023 Audi SQ8, 2023 Audi RS Q8, and 2023 Audi Q8. However, it is still accessible from the selected car via links, so may be relevant.

NOTE:

Also applies to the Audi S 6 and the Audi RS 6.

Features of the refrigerant system:

Restrictor
Reservoir
"Denso" A/C compressor with A/C Compressor Regulator Valve -N280-. Refer to Refrigerant Circuit (vehicle-specific service information) and the Parts Information.

The A/C compressor installed at the factory for a 10-cylinder TFSI engine (Audi RS 6) has a smaller quantity of refrigerant oil (70± 10 cm ) than the A/C compressor for the 10-cylinder FSI engine (Audi S 6) and other engines (130 ± 10 cm ) due to the different testing procedures for the engine (for the 10-cylinder FSI and 10-cylinder TFSI engines, the A/C compressors at present differ only in part number and quantity of refrigerant oil, see also the A/C compressor data plate). When adjusting the total oil quantity in the refrigerant circuit for a 10-cylinder TFSI engine (Audi RS 6) at the factory, the oil quantity that was reduced in the A/C compressor (60 ± 10 cm ), has to be filled somewhere else in the refrigerant circuit. This is not necessary in service because the replacement A/C compressor is delivered with the original oil capacity (130 ± 10 cm ) (it would only be necessary in service if a new A/C compressor with a lower oil capacity is being installed). Refer to the Parts Information.

NOTE:

The replacement compressor contains the full quantity of oil intended for the refrigerant circuit. If the A/C compressor is being replaced, the quantity of oil in the A/C compressor must be adjusted.

The Audi A6 are equipped with different A/C compressors depending on engine and vehicle date of manufacture.

Different versions of this A/C compressor are available as a replacement part, therefore note the exact part number and refer to the Parts Information.

A data plate may be attached to the A/C compressor by the manufacturer, indicating the part number and refrigerant oil quantity.
