Can someone tell me if it is possible to set up the climatronic to automatically recirc the air if the car pulls up in traffic?

My old Beemer used to do it and it is great to prevent exhaust fumes etc coming into the car.

Thank you

Thats sounds like a good idea, can see a problem though, how would it differentiate between being sat in traffic and when youre sat on the drive on a cold morning trying to de-mist, having re-circ on will take much longer.
