Have you got auto climate control ?

Anubisxc70 · Dec 12th, 2017, 17:52

yes it say auto or man. .........

Could it be that the auto is changing things up frequently ?
Try manual and see if it quietens down.

I don't have the auto. I recall some people having this kind of issue when a sensor was disturbed. Someone more familiar will be along I'm sure.

Could be the Recirculate air flap adjusting if you have the Air quality sensor installed.

Thank you Brendan and Oragex
Is there any way to make that flap more silent? or its one of those things we have to get used to it?

I remember mine was also playing a while ago.. maybe it was because the air quality sensor was failing? Since a while it has been silent (perhaps by now the sensor is completely gone). I always use the manual mode for the climate control.

1) What is the expected lifespan of the sensor?

2) When the system springs into "auto", how long will it stay on "auto"?

Early on I could drive behind a smoky truck and the system would close. I could repeat it.

I always took it out of recirc once clear of the bad air source so I never experienced it going back to fresh by itself.

Now my AQIS system does not react as fast.
