The invention relates to a method and an arrangement for controlling a drive unit ( 1 ), especially of a vehicle, having a combustion engine ( 5 ). The method and arrangement make possible a correct charge control when utilizing a secondary air charger ( 10 ) as well as make possible a diagnosis of the secondary air charger ( 10 ). Secondary air is blown into an exhaust-gas system ( 15 ) of the combustion engine ( 5 ) via the secondary air charger ( 10 ). The secondary air charger ( 10 ) is driven by a pressure drop across an actuating element ( 20 ) for adjusting an air supply to the engine ( 5 ). The actuating element ( 20 ) is driven for adjusting an air supply to the engine ( 5 ) corrected in dependence upon an air mass flow driving a turbine ( 25 ) of the secondary air charger ( 10 ).
