Default HVAC air quality sensor problem

Not a biggie obviously, but I do tend to run the HVAC in "auto-sensing" mode to keep out crud from exhausts in front.
VCDS threw up this: 01592 - Air Quality Sensor (G238) 57-10 - Electric Circuit Failure - Intermittent

Does anyone know where this sensor is and if it's easily accessible/replaceable?

Often wondered what that was.

Never even knew there was an air quality sensor! How does one run the HVAC in "auto-sensing" mode?

You press the relevant button on the HVAC controls Mark! RTFM. It has a recirculating arrow with an A in it IIRC.
(It has an indicator light in it too and stays on between restarts so set and forget; I'll try to find a picture....)

Many thanks MJ. I just had a rummage on ELSA and it was talking about the "Plenum Cover" but apart from being under the bonnet it wasn't clear where.
I'll try replugging it and blowing out crud, mines bound to be covered in it!
Obvious place really, right under the cabin air filter.

It's the mirror button to the standard recirculation one but has an A on it as well as the looping arrow. Drivers side of the little grille (alarm sensor?).
Press once to engage and leave it on.
The system takes about 30 seconds to warm up from start before becoming active. When it activates by detecting pollution it has a time delay after going "clean" so won't constantly flip-flop between incoming air and recirculation.

Just to add that our sponsors seem to have used ones cheap enough should I need one; part number is 4B0907659B and common to a few other VAG models.

Sure its a 4B number and not 4D? The one in the A6 (4B/C5 chassis) is quite different to the D2 sensor and has a nasty habit of letting all the magic smoke out.

Well it looks the same and they are listed by A8Parts (and some other sellers) for a number of "Prestige" models. e.g. https://www.ebay.co.uk/itm/VW-PHAETO...9/272528915618
I'll take a look at mine when it's daylight, dry and not blowing a hoolie!

Curious. I just checked Etka and that is indeed the number, despite only being used in the D2!

I wonder if the part was developed for the C5, used on the D2 (but not the C5 for maybe cost reasons?) and then on a few other expensive models?
I can't recall if this function was there in PF models to be honest.
I'm not familiar with the C5 version (is it a simpler/cheaper item?) but various references online suggest the D2 part might even have ended up in Bentleys as well as the Phaeton referenced above!
