What does this part do?

[Eben]

MY diagnostics brought up this part

http://www.realoem.com/bmw/showparts.do?model=AL72&mospid=47634&btnr=64_0700&hg=64&fg=45

I then checked it and found the plug was out, tried to push it back in but its like I am forcing it to go in and doesn't want to fit properly.

At the moments nothing is working only the display and all that but the fan is not coming on and no AC...

Anyone know more about this part and its function?

Sorry mate. :thinking: I am really clueless about this??
Maybe one of the other fanatics can be helpful.
Good luck.

Check that there are no broken parts (plastic clip, etc) still in the socket.
Do you have it the right way around? Most plugs are polarised
Did you squeeze the retainers before plugging it in
Then, most important, take off one leg of the battery before you start fiddling

If you put the Aircon re-circulation on the A with the three arrows encircling it, it is supposed to sens the air quality from the outside and only let in fresh air when the quality is good. This is the sensor responsible for measuring the air quality. Also called a pollutants sensor.

Ok so this wont make the whole ac system not work only the panel coms on and even with the diagnostics machine it didnt fire up so must be that resistor thing behind the cubby thats giving problems
