Abstract: A method for determining the state of loading of a particle filter in an exhaust system of a turbocharged internal combustion engine is provided. To determine the state of loading, a position of a control mechanism of the turbine of the exhaust turbocharger is detected and compared with the position during operation of the internal combustion engine with the same operating parameters with the particle filter unladen. An air mass meter is provided in order to be able to distinguish a change in the pressure situation at the turbine of the exhaust turbocharger due to a rise in the exhaust gas backpressure owing to increasing loading of the particle filter from a change in the pressure situation owing to leakage of the air supply system. An internal combustion engine having a control unit which is configured to carry out such a method is also provided.
