Abstract

A method for diagnosing a component in a gas-routing system of a supercharged combustion engine having an electrically operable compressor, the method including activating the electrically operable compressor after the combustion engine has been shut off, opening a flow path through the gas-routing system, measuring a state variable in the gas-routing system, and detecting a fault of the component as a function of the measured state variable.
