Next find the "analog" section of INPA and you'll see a section where "Oelniveau [mm]" as an option. This is what the actual sensor is reporting a distance up in mm of the sensor.

In this example, I completely drained the oil in my car to verify this. Thus, 0 [mm] was reported.
NOTICE: the permittivity was reported also as 0 -- this would indicate there is NO OIL in the sump; not safe to start the car. The KOMBI would also report this as "NOT OK" when trying to evaluate the oil before starting the car.
