Why is Your BMW Check Engine Light On in Walnut Creek?


The illuminated check engine light is never good news about your vehicle.


Ignoring the problem indicated by the check engine light for longer will continue to mount.


Through preventive maintenance, the check engine light issues can be easily determined.


Moreover, the check engine light of the BMW can be illuminated for many reasons such as: • • • •

Failed sensor Loose gas cap Broken connector Cracked wiring


The following points define the reasons behind the check engine light in your BMW.


Failed mass airflow sensor


Mass airflow sensor measures the air coming into the engine to make the right amount of mixes with fuel.


When it fails, the check engine light turns on due to the issue in the air/fuel mixture in the engine.


Worn spark plugs


Spark plugs supply the spark to ignite the air/fuel mixture and create an explosion to produce engine power.


But, the worn spark plugs or plug wires will result in a check engine warning.


Damaged catalytic converter


Catalytic converter is a part of the exhaust system that reduces toxic gases and pollutants.


If it is going out, then rotten-egg smell along with the check engine warning found in BMW.


Faulty oxygen sensor


In a BMW, the oxygen sensor measures how much unburned oxygen is in your exhaust.


A faulty oxygen sensor will turn the check engine light while driving the vehicle.


Loose gas cap


The tight gas cap will create a vacuum seal within the cap for its smooth functioning.


If the gas cap is loose, then the check engine warning light comes on automatically.


Conclusion


Through preventative maintenance service the check engine light can be diagnosed.


Consult with a reputed mechanic to fix the check engine light issues in the BMW.
