Abstract
An internal combustion engine has an intake system () and an exhaust gas system (). An exhaust turbocharger of the internal combustion engine has a compressor () arranged in the intake system () and a turbine () arranged in the exhaust gas system () of the internal combustion engine for driving the compressor (). In order to diagnose the intake system (), a charge pressure (PHS_AIC_DOWN) of the compressor () is determined in a predetermined operating state of the internal combustion engine. A leakage of the intake system () downstream of the compressor () is recognized if the determined charge pressure (PHS_AIC_DOWN) is lower than the predetermined base charge pressure (PUT_BAS) in the predetermined operating state.
