Capacities For AUDI 100 / AUDI A6 (4A_) Through My 1998

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 a modified hole have been installed at the factory since 11/1997 (colored). In order to distinguish between the two restrictor versions, the one with the smaller hole (1.54 mm) is colored yellow. The restrictor with the larger hole (1.83 mm) is not colored.

The Audi 100 and Audi A6 were equipped with different A/C compressors depending on engine and production period. Exclusive use was made at the start of production of "Zexel / Valeo" A/C compressors. As of MY 1996, "Denso" A/C compressors were gradually introduced for vehicles with 6-cylinder engines.

From MY 2006, the "Zexel / Valeo" designation was changed to "Valeo".

From 09/1994, 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 (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 number 8A0 010 126 P).

After charging refrigerant circuit on vehicles manufactured through 10/1994, check the capacity stated on label in vehicle and correct if necessary, or affix a label with the correct capacity part number 8A0 010 126 P over the existing one (modified capacity).
