BMW 525i Control Unit EGS
The OEM BMW 525i control unit ECU is otherwise known as an engine control module. It controls aspects within the engine to increase performance. The main job of the ECU is to monitor the air-fuel mixture, idle speed and ignition timing. When the genuine BMW 525i control unit ECU begins to fail, you may notice a significant decrease in engine speed and responsiveness.
Finding a replacement ECU isn't difficult when you shop by model. Order your BMW engine performance parts directly from the factory and you also get fast shipping. After a quick swap of the defective unit, you'll be back to enjoying the level of driving satisfaction you once did.
