Abstract: An air flap device for a motor vehicle, to a plurality of jointly adjustable air flaps and to an actuator for adjusting the plurality of air flaps between a closed position and an open position, the air flap device including a radiative detection device for detecting and assessing a position of the plurality of air flaps; the radiative detection device having a radiation source and a radiation receiver, the radiation source emitting an electromagnetic test radiation in the direction toward the radiation receiver, at least one air flap as a test air flap having a test section through which the test radiation is able to radiate, the test section being situated in the propagation path of the test radiation from the radiation source to the radiation receiver in such a way that only when the test air flap is in a predetermined reference operating position at least a portion of the test radiation radiates through the test section toward the radiation receiver and reaches the radiation receiver with an irradiation r

Abstract: A vehicle tank, in particular for holding a fuel, in particular gasoline and/or diesel fuel, having: a first and a second partial shell, wherein the first and second partial shell are connected to one another in a partial shell joining area, and a barrier layer substantially, preferably completely, covering an outer surface of the first partial shell and an outer surface of the second partial shell, respectively, wherein the barrier layer spans the partial shell joining area on an outer surface of the vehicle tank.
