ABSTRACT:
The invention is directed to a method for operating an internal combustion engine including an actuating member in an air supply for adjusting an air mass to be supplied to the engine. In the method, a position of the actuating member is adapted to an instantaneous operating state by a short-time adaptation and a position of the actuating member is adapted by a long-time adaptation to compensate for longer term influences on the position of the actuating member. For a long-time adaptation, a long-time adaptation value is formed for the position of the actuating member in dependence upon a minimum short-time adaptation value for the position of the actuating member which was formed during the short-time adaptation. A leakage in the air supply is diagnosed in dependence upon the long-time adaptation value.
