| Vehicle model | Production period | Capacity in grams | Differing features of this refrigerant circuit |
|---|---|---|---|
| Audi A8 | From 5.94 to 11.97 | 750 + 50 |
|
| As of 11.97 | 800 + 50 |

Restrictors with a modified hole have been installed at the factory since November 1997 (yellow colored). The capacity was increased by 50 g for vehicles with a yellow colored restrictor.
In order to distinguish between the different restrictor versions, the restrictors with a smaller hole are yellow (1.54 mm) or red (1.42 mm) colored. The restrictor with the larger hole (1.83 mm) is not colored.
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). The red colored restrictor is not to be installed into these vehicles.
Exclusive use was made at the start of production of Zexel / Valeo A/C compressors. As of model year 1996, production was gradually switched to Denso compressors. Refer to [For engine(s) BPY, CETA, CCTA, CDMA, CEPB] Description and Operation .
Beginning the production year 2006, the name of the Zexel A/C compressor was changed from Zexel to Valeo.
