Poor cooling performance
Continuous activation and deactivation of the compressor
If the fault mentioned above occurs on this vehicle model,
the problem may be related to a defect
on the filter drier for the air conditioning system. A lack of porosity in this part results in a pressure increase at high exterior temperatures, as a consequence the compressor is switched off. In this case the amount of refrigerant in the system should be checked first. If the amount of refrigerant in the system is in accordance with the information from the vehicle manufacturer, the filter drier (A) on the condenser should be replaced.
(Hella article number: 8FT 351 335-141) Then check the air conditioning system for correct function.
Note: In relation to this aspect please follow the general information on diagnostics for troubleshooting air conditioning systems and the installation instructions from the vehicle manufacturer.
