Capacities for Audi A4 (8D_) 1995 to 2002: Notes

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.

Vehicle model	Production period	Capacity in grams	Differing characteristics of this refrigerant circuit
Audi A4	From 11.94 to 11.97	650 + 50	Restrictor not colored
	11.97 on	700 + 50	Restrictor colored (yellow) Showa condenser (distinguishing feature )
	11.98 on	550 + 50	Restrictor colored (yellow) AWG condenser (distinguishing feature )
Audi RS4	05.00 on	650 + 50	Restrictor colored (yellow)

NOTE:

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 yellow colored restrictor.
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 A4 was equipped with 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.
Replacement restrictors with different holes (not colored, yellow colored, red colored) are available. If a vehicle is equipped with a different restrictor, add more or less refrigerant depending on type (→ Table). After charging, amend capacity stated on label or affix label indicating new capacity.
Depending on manufacturer, color of red restrictor may tend more towards orange.
As of November 1998, Audi A4 models have also been equipped with "AWG" condensers (initially approx. 10000 vehicles with chassis numbers between 8DXA 065 253 and 8DXA 077 026). The specified capacity for vehicles with these condensers differs from those with "Showa" condensers. The condensers can be identified on the basis of certain characteristic features → Distinguishing featuresDistinguishing features of "Showa" and "AWG" condensers .
If the condenser installed is replaced by one with a different part number, check the capacity indicated on the label in the vehicle and amend if necessary or affix a label with the correct capacity over the existing one → 87 - Air conditioning and → Electronic Parts Catalog ETKA.
