Oil level indicator
The M5 is equipped with an electronic oil level
indicator. The oil level is indicated in the
information field of the on-board computer
(BC) in the instrument cluster.
The average speed information was removed
from the BC menu to accommodate the oil
level indication in the on-board computer.
The display is selected with the BC control.
The sensor is the quality and condition sensor
(QLT) from the E65. The entire measurement
logic is resident in the engine management
MS_S65.
The long-term value last stored is shown after
starting the engine.
Basically there are two different measuring
methods: Long-term measurement and quick
measurement
Long-term measurement
The engine management permanently
measures the oil level and derives the mean
value from the measurement results which is
then shown in the on-board computer.
The DME requires an engine operating time of
approx. 10 minutes to establish a long-term
value.
Quick measurement
The quick measurement method provides the
option of measuring the oil level with only a
short time delay (e.g. topping up oil, oil
service).
The quick measurement must be initiated
manually by pressing and holding the BC
button (approx. 2 seconds) in the oil level
indication setting.
The displayed value indicates the quantity of
oil above the minimum level. The value should
be between MIN 0.0 l and MAX 1.0 l.
Display: 1.5 l means overfilled, the bar
indicator is additionally filled above Maximum.
Values from 1.0 to 1.4 are suppressed.
