Volvo S60 2005 - Air Quality Sensor Replacement 30676508

I have a Volvo S60 from 2005 (facelift), D5244T, M56 manual transmission. It is equipped with an air quality sensor, which was throwing a fault. Since the official replacement sensor (31369324) costs 350 USD, I ended up purchasing a brand new aftermarket sensor in a HERTH+BUSS ELPARTS box (70604009) for 70 USD, while the sensor itself was actually branded as Hella (6PX 012 684-061), while in turn the sensor was produced by the company Paragon (which also makes the genuine sensor). Warning - this only applies to Volvo cars manufactured from 2005 till ~2008 (not 100% sure). This does NOT apply to cards manufactured from 2000 till 2004.
