Capacities For AUDI 100 / AUDI A6 (4A_) Through My 1998
Features of the refrigerant system:
- Restrictor (not colored)
- Reservoir
- "Denso" or "Zexel / Valeo" A/C compressors. Refer to [For engine(s) CTUA, CEUC, CRDB, CGXB, CPNB] System Overview - Refrigerant Circuit (vehicle-specific repair information).
| Vehicle model | Production period | Capacity in grams | Differing features of this refrigerant circuit |
|---|---|---|---|
| Audi 100/Audi A6 | From 10/1992 to 03/1997 | 750 + 50 |

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 yellow colored. 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. From MY 1996, "Denso" A/C compressors were gradually introduced for vehicles with 6-cylinder engines.
From 2006, the "Zexel / Valeo" identification 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 no. 8A0 010 126 P).
After charging refrigerant circuit of vehicles manufactured through 10/1994, check the capacity stated on label in vehicle and amend if necessary or affix a label with the correct capacity part no. 8A0 010 126 P over the existing one (modified capacity). Refer to Commercial Names and Designations (vehicle-specific repair information).
