[Guest benny147]

the clunking noise is the clutches activating  when the electro magnets are activated by pressing the on/off button

C3 has an electronic clutch on the A/C compressor, the compressor does not run all the time, is controled by the climat controle temperature setting, the lower temperature set the longer it runs.

On my car I can just about hear it on tickover but not wlist driving. If it is verry noisy check the bolts holding the pulley on to the compressor.
