Hello
I went to get my A/C re-gassed at a local independent mechanic (Not a Volvo specialist or an A/C specialist - a local mechanic recommended by a neighbour as we just moved to this area).
Apparently it holds a vacuum and the compressor clicks on and off, but there is no cold air.
His scanner has shown the following code: B102E09, which he reckons is a faulty air quality sensor.
I thought the AQS controlled the recirculation / intake when on Auto.

Thanks in advance for any advice. Cheers
