If your Mercedes' check engine light ever lights up; don't ignore it. Check the above-said components before going to a nearby car service center. Doing nothing about this warning light can prove very costly.

1. Engine Light On In
Your Mercedes?
Check These 5
Parts Immediately

2. So, your Mercedes’ check
engine light came on out of
the blue…

3. You must check the following parts before
going to the nearest service center...

4. #1 - The gas cap

5. This is the first part you
should check; if your
Mercedes' CEL ever starts
flashing.

6. Because if the gas cap is
lost or damaged, the CEL
may light up.

7. Fix the defective gas cap before it leads to an
expensive emissions issue.

8. #2- O2 sensor

9. Done checking the gas cap!!! The next
part you should look at is the O2 sensor.

10. A bad O2 sensor may
contribute to a
rich/lean air-fuel
mixture.

11. This may signal the
onboard computer to
activate the check engine
light.

12. #3- Carbon fouled
spark plug

13. Yes, the CEL will light up if
the spark plugs are
carbonized.

14. You need to clean off
the spark plug tip; so
that it can fire
properly.

15. If spark plugs are damaged
beyond repair, replace
them.

16. #4- Catalytic
converter

17. The catalytic converter,
if clogged, can restrict the
flow of exhaust
emissions.

18. As a result, the performance
of the engine will suffer.

19. This will give the onboard diagnostic system a
reason to activate the CEL.

20. #5- MAF sensor

21. This sensor basically
monitors the amount of air
entering the engine.

22. Incorrect readings by this
sensor may cause the car
computer to turn on the CEL.

23. Wrapping Up

24. If your check engine light
starts flashing, check
these parts immediately.

25. Visit the service center
only if you fail to find the
culprit.
