Electronic oil measurement
General information
The electronic oil measurement has two measur‐
ing principles:
▷ Monitoring.
▷ Detailed measurement.
When making frequent short-distance trips or
using a sporty driving style, for instance when
taking curves aggressively, regularly perform a
detailed measurement.
Monitoring
Principle
The engine oil level is monitored electronically
while driving and can be shown on the Control
Display.
If the engine oil level is outside its permissible
operating range, a Check Control message is
displayed.
A red indicator light indicates that the en‐
gine oil pressure is too low.
Functional requirements
A current measured value is available after ap‐
prox. 30 minutes of normal driving.
Displaying the engine oil level

System limits
When making frequent short-distance trips or
using a sporty driving style, it may not be possi‐
ble to calculate a measured value. In this case,
the measured value for the last, sufficiently long
trip is displayed.
