Capacities for Audi A4 (8E_) from 2001, Audi A4 Cabriolet (8H_) from 2003
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:
- Restrictor (yellow or red colored)
- Reservoir
- "Denso" compressor with A/C Compressor Regulator Valve N280 (without A/C clutch)
| Vehicle model | Production period | Capacity in grams | Differing features of this refrigerant circuit |
| Audi A4 | As of 11.00 | 500 + / - 20 | Restrictor yellow or red colored |
| Audi RS4 | As of 07.05 | 440 + / - 20 | Red colored restrictor |
NOTE:
- Replacement restrictors with different holes are available (yellow colored 1.54 mm, red colored 1.42 mm).
- Depending on manufacturer, color of red restrictor may tend more towards orange.
- To avoid altering the cooling output of the air conditioner, red or yellow colored restrictors must only be installed. Yellow colored restrictors were installed in model year 2001. Red colored restrictors were installed as of model year 2002. The restrictor modification (a red colored restrictor may also be installed in vehicles of model year 2001 instead of a yellow colored restrictor) does not alter the capacity for these vehicles.
- Various compressors have been installed depending on production period and engine (these compressors have no A/C clutch).
- At the start of production exclusive use was made of type "6 SEU 12" and "7 SEU 16" compressors from "Denso". With effect from Model Year 2004 a gradual change was made to different "Denso" compressors (types "6 SEU 14" and "7 SEU 17" ) → 87 - Air conditioning and → Electronic Parts Catalog ETKA.
- For the Audi RS4, a condenser with smaller internal volume is installed, therefore the capacity for this model is less than for other models → Electronic Parts Catalog ETKA.
