Increased crankcase pressure
The function measures and warns in case of increased crankcase pressure in a way that the pressure-increase value is
obtained by comparing unfiltered and filtered crankcase pressure. The filter is designed so that a sudden pressure-increase
gives a warning while a slowly increasing pressure, caused by normal wear, does not generate a warning.
Water in fuel
A sensor in the fuel system's pre-filter activates yellow warning when the water level becomes too high.
