6 Series 650i (N62TU) Coupe
The oil condition sensor measures the following ratings:
-
Engine oil temperature
-
Oil level
-
Engine oil quality
The oil condition sensor sends the recorded measurement values to the DME.
A bit-serial interface is used to transmit the signal to the DME.
The integrated supply module supplies voltage to the oil condition sensor.
-
Oil pressure switch
The oil pressure switch provides the DME control unit with an indication of whether or not there is sufficient oil
pressure in the engine.
The oil pressure switch is connected to the integrated supply module. The signal is fed through the integrated
supply module to the DME.
> E70
The oil pressure switch is directly connected to the DME control unit.
The signal from the oil pressure switch is checked for plausibility in the DME.
To do this, the signal from the oil pressure switch is observed after the engine has been switched off.
After a certain time, the oil pressure switch should not detect any more oil pressure. Is oil pressure is detected,
the DME responds by recording a fault memory entry.
The following control units and other interfaces are involved in the digital engine electronics (DME):
-
DME control unit
3 additional sensors are located on the board in the DME control unit:
•
Temperature sensor
•
Ambient-pressure sensor
•
New: Voltage sensor
The thermal monitoring of components in the DME control unit is carried out by the temperature sensor.
The ambient pressure is required to calculate the mixture composition. The ambient pressure reduces as the
height above sea level increases.
The voltage sensor on the DME control unit board monitors the power supply using terminal 87.
The DME control unit is connected to the vehicle electrical system by 5 connectors.

The DME control unit is linked to the safety and gateway module (SGM) and to the rest of the bus system by
means of the powertrain CAN.
> E60, E61, E63, E64 from 09/2005
The body gateway module (KGM) is the gateway between the PT-CAN and the rest of the bus system.
> E70
The junction box electronics (JBE) is the gateway between the PT-CAN and the rest of the bus system.

Valvetronic control unit
The 8-cylinder spark-ignition engine has its own Valvetronic control unit.
Communication between the DME control unit and the Valvetronic control unit takes place via a separate local
CAN (local, two-wire CAN bus).
The DME activates the Valvetronic control unit via a separate wire.
The DME control unit calculates all values needed to actuate the Valvetronic. The Valvetronic control unit
