A tank venting system () for a motor vehicle () has a filter () to filter a venting gas () of a fuel tank () of the motor vehicle (), a pump () to generate a flushing air stream () in order to flush the filter (), and a control unit () that, for purposes of performing a leak test, is configured to detect a pressure signal () that is dependent on the gas pressure (P) present in the fuel tank () and to check whether the pressure signal () meets a prescribed leakage criterion (). The pump () is fluidically interconnected between the filter () and a shut-off valve (), whereby the shut-off valve () is configured to fluidically couple the pump () to an inlet site () of a fresh air system () of an internal combustion engine () of the motor vehicle (), and whereby the control unit () is configured to operate the pump () for flushing the filter () as well as for performing the leak test.
