Auto recirc does this automatically so it has a sensor to detect the incoming air and sense whether its smelly or smoky or dirty and then change to recirculating air if it is. The base climate doesn't have this, i had it on my old car and it was good, but i figured that just upgrading the unit would not add the sensors that are needed for this. However I am unsure if all cars are built with the sensor, and that it only works with the extended climate unit.

Thank for explaining it.
Problem is that I have never left the CC on auto so I cannot confirm this.
If I leave it on auto, compressor light is always on whatever temp I select.
