Random beeping on Skoda Octavia MK3 Facelift 2.0TDI

Hi everyone,

Can someone please tell me what is this random beeping sound?

I have no errors on the dash and a scan with obd11 gives “air quality sensor”. This error has been there since some time but the beeping is new. I am assuming that this is not related to the beeping.

The sound can be heard at 0.5, 0.25,0.36 and 0.46 timestamps of the video.

Thanks
