I can't find much on this fault code except from people who have retrofitted FL AC panels into pre-FL Octavias. There's also little outside of this forum that I can find.

Basically it posts to a fault in the wiring for the air quality sensor. But where is it on a Yeti and what does it do?

 

I've not changed anything electrical since I retrofitted a Columbus and MDI; so can;t work out why it has cropped up since then.

 

Any thoughts?

I thought it was on the air intake into the cabin before the pollen filter. Probably deep inside the dash.

My guess is that it would probably be in the same location as in the Octavia II.

I changed my pollen filter last month. Is it possible that I've damaged a wire or dislodged the sensor?

Never had any issues with my Octavia.

Thanks for the links. Still not 100% sure where it is, but will have a look shortly.

The first link doesn't allow me to look at the forward links to removing the bodywork. Is there a way around this?
