Common Causes of Service Engine Soon Lights in BMW Vehicles

There are several common causes of a service engine soon light in BMW vehicles, including:

• Fuel Injector Issues: Fuel injectors are responsible for delivering fuel into an engine’s cylinders at precisely timed intervals. If they become clogged or malfunction due to age or contamination, they can cause misfires or no-start conditions.

• Malfunction in Ignition Coils or Ignition Modules: Ignition coils turn low voltage electricity into high voltage electricity for spark plug ignition. If these components fail due to age or contamination, they can prevent spark plugs from firing correctly and cause stalling or misfires.
