Can anyone help me please? My windscreen is not clearing as it used to and is misting up. I am getting error code B1927 - Pollution Sensor signal low.

Does anyone know which sensor this is and where it can be found and how to test and repair?

4 weeks and still no replies? Nobody knows where it is?

The answer was in the forum but i cant post links but i will post the posts:

yellowstilo: The AQS sensor is behind the openings at the lower part of the climate control unit in the middle.

T14086: under scuttle panel ( I assume you mean pollution sensor) very unlikely to go wrong.

Anybody know where the pollution sensor actually is, out of these 2 locations mentioned in the last post ? I still have code B1927 pollution sensor fault and no air con. Thx David

Under the windscreen scuttle panel. It won't stop the aircon working, it just sends a signal to close the outside air flap.
