Service Information

- Replacement A/C compressors supplied by Audi are filled with 250 cc (8.5 fl oz) of A/C refrigerant (PAG) oil. This is the total A/C system refrigerant oil capacity.
- Do not top-off a charged refrigerant system. Instead, discharge, evacuate and recharge the system.
- Only use new O-rings specified for use with R-134a.
- O-ring and torque specifications also apply to threaded connections in the A/C lines.
- The variable displacement A/C compressor varies piston stroke and output depending on load requirements and suction pressure.
