A/C refrigerant system, servicing: Notes
WARNING: This page does not describe the selected car, but rather 15 other vehicles, including the 2005 Audi allroad, 2004 Audi allroad, 2004 Audi A6, 2003 Audi allroad, and 2003 Audi S6. However, it is still accessible from the selected car via links, so may be relevant.
NOTE:
- No refrigerant must be added to the refrigerant circuit (discharge, evacuate and recharge refrigerant circuit). See A/C REFRIGERANT SYSTEM (R-134A), DISCHARGING .
- Replacement compressors contain the total amount of refrigerant oil to be filled into the refrigerant circuit:
- Service work on refrigerant circuit, see REFRIGERANT CIRCUIT, SERVICING . Checking cooling performance, see A/C SYSTEM COOLING PERFORMANCE, TESTING .
- Checking pressures in refrigerant circuit.
- Starting September 1998, there was a running change in production from the version "1" air conditioner to the version "2" air conditioner. See AIR CONDITIONING CHANGES .
- Up to model year 2001 only compressors with A/C Clutch -N25- were installed. As of model year 2002 compressors with A/C Clutch -N25- or with A/C Compressor Regulator Valve -N280- are installed depending on engine type. See COMPRESSOR, WITH A/C CLUTCH -N25- and COMPRESSOR, WITH A/C COMPRESSOR REGULATOR VALVE -N280- .
- When installing refrigerant lines/hoses and retaining bracket, make sure there is a sufficient gap between belt, bracket and belt pulley.
- Zexel-, Sanden- and Denso-compressors require different refrigerant oils: See A/C REFRIGERANT R-134A AND REFRIGERANT OIL (PAG), CAPACITIES .
- Different filling capacities for refrigerant oil depending on compressor type and version. See A/C REFRIGERANT R-134A AND REFRIGERANT OIL (PAG), CAPACITIES .
- The suggested diameters of the O-rings and gaskets and the tightening torques pertain also the bolts of the refrigerant lines or hoses between the separate components.
- Only install O-rings that are approved for Refrigerant R134a (currently red, light purple and dark purple).
- Adapter for service station to connect to refrigerant circuit.
- All service and repair work not covered in this Repair Manual.
