Author: Michael II:
"The interior becomes too cold after a longer drive, with insufficient or no airflow from the ventilation vents. This issue affects vehicles with a 4-cylinder engine and a Zexel compressor (the clutch of the air conditioning compressor has a brass-like color; compressors with a black clutch are not affected)." The connectors on the vaporizer show visible signs of frosting.
Cause:
Due to insufficient suction pressure, the refrigerant in the circuit becomes so cold that temperatures below freezing occur on the surface of the evaporator, causing any condensation to freeze and the entire evaporator to ice up. This prevents any airflow. By pressing the ECON button on the climate control panel, the compressor is switched off and the evaporator defrosts. If you continue driving after that, the evaporator will freeze up again!
Solution:
Replace the compressor. Please be sure to install the A/C compressor with part number 8D0 260 805 M in the event of evaporator icing.
Please provide the German text you would like me to translate.
Bye.
