	Recirculated air flap actuator - location		GF09.50-P-3101-01AM
	Recirculated air flap actuator - task	The air recirculation flap actuator changes the intake air guidance upstream of the compressor over continuous adjustment (0 to 90°) of the air recirculation flap.
	Recirculated air flap actuator - design	The recirculated air flap actuator consists of: Housing Electrical connection Actuator motor Actual value potentiometer 2 Recirculated air flap
	Recirculated air flap actuator - function	The air recirculation flap actuator is actuated by the ME-SFI [ME] control unit (N3/10) by means of a ground signal. The actual value potentiometers sends the current position of the throttle valve to the ME-SFI [ME] control unit. The air recirculation flap is always closed at full load (maximum boost pressure) and when starting (getting the compressor to rotate).
