BMW Service Engine Soon Light Car Shaking

So what is service engine soon light?    

The service engine soon light or malfunction indicator lamp happens to be part of your vehicle’s on-board diagnostics system. You should know that the system is run by your vehicle’s computer, which is also known as the electronic control module (ECM).

In this modern-day, the electronic control module operates virtually on every electronic or electrical system of your BMW vehicle. And also, it examines out of range operating parameters that are conveyed by the many sensors and actuators, which includes:

  • The Idle speed motor
  • The Idle air solenoid
  • The Fuel pump
  • The Fuel injectors
  • The EGR solenoids
  • The Canister purge solenoid
  • The Air meter sensor
  • The Evaporative emission sensor
  • The Camshaft and crankshaft sensors
  • The Knock sensor
  • The Oxygen sensor
  • The Engine coolant sensor

A perfect instance is, an actuator or an unpredictable operation of the fuel pump, a sensor may spot a misfire, unusual output voltage and poor fuel injection or any other situation that might interfere with the engine emissions and performance.

Normally, the computer system of your BMW vehicle would wait for a few cycles or try to rectify the problem. But when the computer is unable to rectify the issue, the on-board diagnostics system will have a diagnostic problem code stored in the memory, which in turn causes the service engine soon light to keep flashing.

You should be informed that there are two basic types of monitoring that your BMW engine computer can do: the continuous and non-continuous monitoring.

For the continuous monitoring, the systems in your BMW vehicle are continuously monitored and checked whenever the engine is on. But some common ones are engine misfire and also engine timing concerns. But if something goes wrong with the two of them, then there will be a serious failure.

But when it comes to the non-continuous monitoring, your BMW vehicle’s engine computer will run the required tests anytime the conditions are right. A perfect example is when your BMW engine computer runs the catalytic converter test, and it has to conduct the test when the catalytic converter is at the ideal temperature.

But mostly, your BMW engine computer conducts two-trip monitoring. And generally, it takes two failures before your service engine soon light will actually come on in your vehicle.
