Even when i don't use the aircon?

Well this morning when i got to work i didn't hear the noise, so hopefully it won't happen again.

You don't have a choice, the AC compressor is always running.

So that would mean that the noise wont happen all the time, just when the AC is "dirty"?

No it happens at different times as required, it changes the positions of the flaps when shutting down to minimise odours.

Then what does the "AC" button on the climate controls do?

Turns the AC on and off however the AC compressor is a variable controlled unit that has no clutch and always runs at a minimum 2%.

The AC system has a climate control to run it and you can't fully disable it like you can with a manual system.
