Four Seasons A/C Refrigerant Discharge Hose P/N:55902
Four Seasons 66769 a/c refrigerant discharge hose for the 2005-2009 Audi A4 / A4 Quattro and other vehicles carries refrigerant out of the A/C compressor on the high-pressure side of the system.
A refrigerant leak, an oily residue at a hose fitting or an A/C that blows warm air can mean this hose has failed. Those signs alone do not prove the hose is at fault, because a low refrigerant charge can show up the same way.
This hose also fits the 2005-2009 Audi A4 Quattro and the 2005-2008 Audi A4.
