Quote:Is the pm2.5 sensor and the air quality sensor the same just on the later versions it uses the om instead of the quality sensor?
No, they are different and serve different purposes. The Air quality sensor is in the engine bay under the same plastic cover (AC air intake).
Quote:I have the advanced air cleaner or ionizer part, just need to install it now. Wiring where do I tap into the power etc on the car all underbonnet or do I have to drag wires into the car itself?
You can get the power and the negative from the engine bay but you will need the LIN wire go inside anyway. So, get a 22/3 AWG 3 Conductor Electrical Wire and pull it in. There is a plastic cover from the engine bay to inside at the passenger side. look at
this. Image 190 and later. You can use a fuse tap, to get the power from fuse box. Negative, just attach the cable to body. LIN, If you already have the heated front seats, tab it to the driver side heat controller LIN wire.
Quote:And I will need the pm2.5 sensor if I some how enable the air quality app. The sensor location is unknown to me. The wiring diagrams are no where near as clear as ford ones.
The PM 2.5 sensor is on the AC . Under the glow box. remove the plastic cover as you are replacing the cabin filter. It's not pre-wired. So, you will need to wire it yourself.
However, it is useless without the app. You cannot trick the sensus (IHU) to download it. I replaced my IHU because it was faulty due to liquid damage. It would not download anything even the map updates. Because it has a certificate inside which does not match to the VCMs and CEMs. I reloaded market certificate from VIDA and that solved my issue but previous owner had not installed the air quality app on it. So, that application does not show up. You see, VOLVO shows applications only matching the VIN. then during download it checks the certificate of the IHU.
In Chinese market there is another PM 2.5 cleaner module called air ionizer located on the front center air vents. Not possible to get without removing the whole dash because it's located between the air docks and the dashboard.
