Functionality AUC system
The AUC sensor is a component of the automatic air recirculation control, or AUC. The AUC control is active as soon as the auto button on the climate control panel is activated. This controls the air quality and decides whether the vehicle will allow air to flow in from outside or whether the air will continue to be used inside the vehicle (recirculation).
The AUC sensor is located outside the passenger compartment and has the task of determining whether the air flowing in from outside is clean or contaminated. If the air is impure, the vehicle remains in recirculation mode. This function was developed especially for construction sites, traffic jams, tunnels and city traffic.
