NOTESConsult this customer complaint after a full check with the diagnostic tool (fault
reading and configuration checks).
WARNING
Check that the computers active in the AIR CONDITIONING function (Injection and
UCH) are correctly configured.
Note:
Before starting any work, check that the noise is indeed coming from the compressor.
Check that the compressor belt is in good condition and check its tension (for engines without automatic
tensioning) (see MR 411, Mechanical, 11A, Top and front of engine, Accessories belt: Removal - Refitting).
Check that the compressor is correctly fixed (see MR 411 Heating and air conditioning system, 62A, Air
conditioning, Compressor: Removal - Refitting).
Check the refrigerant fluid and look for any leaks. Significant loss of fluid causes the compressor to make noises.
(see Technical Note 6001A, Air conditioning, 62A, Air conditioning, Air conditioning: Check).
If the fault is still present, replace the air conditioning compressor (see MR 411, Mechanical, 62A, Air
