GF00.20-P-2009P Engine Oil Monitoring, Function
- MODEL 203 with ENGINE 271 as of 1.6.05, 272, 642 up to model year 08/YoM 07

The oil level check switch (S43) constantly monitors the engine oil level.
The engine oil level cannot be displayed upon driver request with aid of the multifunction steering wheel (MFL) in the multifunction display (A1p13).
An engine oil level warning message "Check engine oil when during refueling stop" is displayed with "circuit 15 ON", "circuit 61 OFF" one of the following conditions:
- Engine oil level has reached "Minimum".
- Oil level check switch (S43) is defective.
- Connection to oil level check switch (S43) interrupted.

In order to perform the diagnosis, the motor electronics control unit (N3/10) or the CDI control unit (N3/9) have to be read out via STAR DIAGNOSIS.

The instrument cluster (A1) receives the sensor data over the Controller Area Network bus Class C (engine compartment) (CAN-C) from the vehicle-specific engine control unit.

Oil change
Following each oil change, the Active Service System (ASSYST) must be reset. On resetting, the remaining distance and the remaining time are reset. Resetting can be carried out via the instrument cluster (A1) or via STAR DIAGNOSIS.
On resetting, the following data are stored:
- Current kilometer reading, rounded to 100 km
- Remaining distance
- Remaining time
- Product of quality factors
- In 5 data records the data of the most recent 5 resets

These data can only be read out via STAR DIAGNOSIS.

The starting distance (internal mileage) is reduced if the prescribed quantity of oil is not filled in when the oil is changed.
