WARNING: This page does not describe the selected car, but rather 17 other vehicles, including the 2009 Audi S4, 2009 Audi A4, 2008 Audi S4, 2008 Audi RS 4, and 2008 Audi A4. However, it is still accessible from the selected car via links, so may be relevant.

Characteristics of refrigerant circuit:

"Denso" or "Zexel" compressor → 87 - Air conditioning and → Electronic Parts Catalog ETKA

Vehicle model	Production period	Capacity in grams	Differing characteristics of this refrigerant circuit
Audi 100/Audi A6	From 10.92 to 03.97	750 + 50	None

NOTE:

If a vehicle is equipped with a yellow colored restrictor as replacement for a non-colored restrictor, add 50 g more refrigerant than specified in the table. In addition, the capacity specified on the label in the vehicle is to be checked and amended if necessary or the existing label is to be replaced with one indicating the correct capacity (affix over old label).
Restrictors with modified hole (colored) have been installed at the factory since November 1997. In order to distinguish between the two restrictor versions, the one with the smaller hole (1.54 mm) is yellow colored. The restrictor with the larger hole (1.83 mm) is not colored.
The Audi 100/Audi A6 features different compressors depending on engine and production period. Exclusive use was made at the start of production of "Zexel" compressors. As of Model Year 1996, "Denso" compressors were gradually introduced for vehicles with 6-cylinder engines.
From September 1994, production was gradually switched from condenser 4A0 260 403 AB to condenser 4A0 260 403 AC.
The refrigerant capacity of 750+50 g applies to all Audi 100 models (regardless of condenser).
Only condensers with part number 4A0 260 403 AC are now available as replacement parts (if necessary make use of label, part no. 8A0 010 126 P).
After charging refrigerant circuit of vehicles manufactured up to October 1994, check capacity stated on label in vehicle and amend if necessary or affix label, part no. 8A0 010 126 P over existing label (modified capacity) → 87 - Air conditioning and → Electronic Parts Catalog ETKA.
