Could also depend on humidity ambient temperature pressure etc. The radiator shutter flaps are designed to restrict engine cooling to help reduce the time for the engine to reach ideal operating temperature in cold climate regions which helps fuel efficiency. The active grille air shutter actuator closes louvers at the front bumper to enhance vehicle aerodynamics in driving situations where cooling and AC loads are relatively low and high levels of front end airflow are not required.

With the shutters closed at high speeds wind drag is reduced. Maybe i am driving it harder then most. Enjoy the many advanced performance features in our BMW vehicles like the Active Kidney Grille.

The system optimizes aerodynamics and coolant temperatures by using electronically controlled slats to control airflow through the grille radiator and engine compartment. When cruising on the highway at steady speeds the grille slats automatically close to improve aerodynamics and fuel efficiency. The active grille shutter assembly accomplishes three things.

If air is required to cool the engine the vents are opened. If high levels of airflow are required the active grille air shutter actuator opens the louvers. Nope it is broken take it to the dealer.

The shutters open and close automatically to control airflow reducing aerodynamic drag and improving fuel efficiency.

Page 1 of 2. 1 Improves aerodynamic efficiency at higher speeds by forcing airflow over the hood 2 Improves emissions by blocking airflow across the radiator at cold startup to speed up engine warmup and 3 increasing passenger comfort by blocking airflow across radiator to improve coolant heat retention. This system activates depending on several temperature thresholds as well as the speed of the vehicle.

This system activates depending on several temperature thresholds as well as the speed of the vehicle. Does anyone know if this is expected. Active Grille Shutter.
