ABSTRACT:
In a method for diagnosis of an exhaust turbocharger for an internal combustion engine, at least one value which characterizes the load on the exhaust turbocharger is determined and compared with a reference value, an event signal being generated in the event of the reference value being exceeded. A wear characteristic number which characterizes the alternating load on the exhaust turbocharger is formed by addition of load signals, in each case one change signal being generated whenever the charger speed of the exhaust turbocharger exceeds a maximum.
