Abstract
Described is a method for detecting a glow plug replacement of an engine, wherein a first value of a temperature-dependent variable is measured at a first glow plug of the engine and, simultaneously, a second value of the temperature-dependent variable is measured at a second glow plug of the engine. The first value of the temperature-dependent variable is compared with a stored reference value of the first glow plug and a glow plug replacement is detected if the difference of the first value from the reference value exceeds a threshold value. According to this disclosure, it is provided that the reference value is a value which, in an earlier measurement, was measured at the first glow plug simultaneously with the measurement of a value at the second glow plug which corresponds to the second value within a predefined tolerance.
