Now the modern vehicles have a well-equipped check engine light that can alert the vehicle owners about the current conditions or problems that arise in the vehicle. But, due to a busy schedule, many vehicle owners will neglect the issues that may, later on, lead to expensive repairs. Go through the slide to know about the reasons behind your illuminated check engine light in BMW.

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

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

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

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

5. 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

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

7. Failed mass
airflow sensor

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

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

10. Worn spark
plugs

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

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

13. Damaged catalytic
converter

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

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

16. Faulty oxygen
sensor

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

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

19. Loose gas cap

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

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

22. Conclusion

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

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