Abstract
A motor vehicle having an internal combustion engine, a differential pressure sensor or two pressure sensors for detecting a pressure difference, which may be in an exhaust tract of the internal combustion engine, and an evaluation unit for evaluating the detected pressure difference. Moreover, the present invention relates to a method for operating a motor vehicle. A controlling arrangement is provided for controlling an automatic start-stop system or an ignition system of the motor vehicle as a function of the result of the evaluation of the detected pressure difference used to detect immersion or submersion of a tailpipe of the exhaust tract in water, sludge, or a similar liquid medium in order to prevent the internal combustion engine from shutting off when the tailpipe is immersed or submerged.
