Re: Can the IAQS Fail ? (SML)
When in auto it allows fresh air into the car so it does not get stuffy inside.

Re: Can the IAQS Fail ? (SML)
Not necessarily, smelling car exhaust or such is not a failure of the IAQS or a problem with a Carbon Cabin Filter. I'll have to look up the exact prerequisites for the IAQS in the Auto position to then switch it to Recirculation thus shutting off Outside Fresh Air. The manual override will obviously do this and that is why you don't smell the outside air. Just so you know for the IAQS to function the air sample has to be pretty dam dirty. Car exhaust will not trigger it. And as for the carbon filters, they are designed for minor smells. And with the small amount of activated carbon in them, they don't last all that long for that purpose. I've replace mine with a brand new one before and on the drive home from work that evening I could smell the rich running Harley in front of me. So don't expect the cabin filter to be like wearing a respirator

So when I drive behind smoky cars with the AUT light on and I can smell the pollution, is there a problem? Has the AUT sensor failed? |
