Tok tok tok A/c compressor noise

[velan]

Hi everyone,Can someone please help me with my latest problem? I just found out that the A/C compressor in my E46 320i is making noise 'tok tok tok' ...kind of a rattle sound when the rev drops to idle. Strangely the compressor doesn't make noise while the car is idling or when the rev is high. Only when the gas peddle is pressed lightly and left off. Furthermore the sound also comes out briefly when the A/C is switched on. i.e when the A/C clutch engages. If the A/C is off, no sound at whatever speed.So can someone please suggest a fix? Where can I bring the car for a fix and what is the estimated cost of repair. Also any where I can buy the reconditioned compressor? I found out that the part no.

Velan,

Sounds more like an air cond bearing problem. You have it checked and triple confirm it before you decide to change. i have seen workshops changing the whole unit when they can actually remove the compressor and only change the bearing. Workmanship and bear should only cost around RM100 or so.

Hi Joey,

Thanks for the tips. I will definately get it checked by an a/c foreman before changing anything.

Thank you.
