Abstract
A diagnostics method and system for a power plant including at least one low-pressure turbocompressor and at least one high-pressure turbocompressor, the turbocompressors being staged and supplying an internal combustion engine, the power plant being fitted to a motor vehicle. The method includes determining a mode of operation of the power plant, determining a power of the high-pressure turbine based on a first set of data and based on the mode of operation, determining the power of the high-pressure turbine based on a second set of data, determining a failure criterion as being the ratio between the power of the high-pressure turbine dependent on the first set of data and the power of the high-pressure turbine dependent on the second set of data, and comparing the failure criterion against stored values to determine whether there is a failure.
