The DME system operates the ignition and fuel injection system with a single control unit. In short, it controls most of the functions within your BMW car engine. It is a very complex and sophisticated computerized engine management system that works and races the engine.
In BMW, the DME control unit maximizes the performance of an engine, reduces the emissions, maintaining the reliability of the vehicle and reduces the consumption of fuel. But if you experience that your BMW is not working properly, keeps high fuel consumption, ignition engine stops working then it can cause DME control unit failure.
How The DME Control Unit Works:
DME control unit accepts input signals from the intake airflow or main mass sensor. DME sensor captures the data that power the operations of your engine. The data includes vehicle speed, air temperature, cylinder identifying sensor, exhaust air, crankshaft plus sensor and accelerate throttle position. After capturing the data from various sensors DME control unit calculated and converted the data in the form of commands and send to the ignition system and fuel injection system. But if the ignition digital motor sensor fails and captures the incorrect data then it can lead to damage the engine and other important components of the vehicle.
