N55 Engine
Digital Motor Electronics (DME/ECM)
The N55 engine is equipped with the Bosch engine management MEVD17.2 :
• The MEVD17.2 is integrated in the intake system and is cooled by the intake air.
• The MEVD17.2 is FlexRay-compatible and directly supplies voltage to the sensors
and actuators.
The top side of the DME housing also serves as the bottom section of the intake
manifold. The housing is contoured in the area of the intake manifold to ensure optimum
air flow. An O ring type seal is installed between the DME housing and the intake. The
plug connections between the wiring harness and DME are water-tight.
