    摘要: A method is described for operating an internal combustion engine in motor vehicles, in which air is supplied to a combustion chamber via a throttle valve and an air supply channel, and in which exhaust gas is conducted through a particulate filter and is returned at least intermittently and at least partially through an exhaust gas recirculation valve into the air supply channel, and in which an oxygen proportion in the exhaust gas is detected using at least one lambda probe. In this context, in an overrun operation, the throttle valve is controlled to close and the exhaust gas recirculation valve is controlled to open, a variable characterizing the oxygen concentration in the exhaust gas is compared to a boundary value, and as a function of the result of the comparison, it is concluded that there is a leakage in the air supply channel.
