Capacities For AUDI A6 (4F_) From My 2005

WARNING: This page is about a different car, the 2023 Audi S3, 2023 Audi RS 3, 2023 Audi A3 Quattro, and 2023 Audi A3. 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 repair 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.
