Thus, the ignition coil of the Mercedes-Benz is turning the low voltage of the battery into the little white sparks which are used for igniting the air to fuel the mixture in the engine. It is an important part of the ignition system alongside the other valuable components. When the ignition coil is powered up, then the outer coil is flushed with charge. If the ignition coil is failed, then you will notice the signs defined in the given slide.

1. How To Diagnose A Bad Ignition Coil In Your Mercedes-Benz by
Mill Valley Mechanic?

2. Ignition coil turns
the low voltage of
battery into a spark
to ignite the
air/fuel mixture in
the engine.

3. In a Mercedes-
Benz, the ignition
coil functions as a
part of the ignition
system alongside
the:
• Spark plugs
• Switch battery
• Distributor
• Alternator

4. When the coil is
powered up, the
outer coil is flushed
with charge,
creating a magnetic
field.

5. Like other
components of the
vehicle, the ignition
coil of the
Mercedes-Benz is
failed.

6. The following points help you to diagnose the bad ignition coil in the Mercedes-Benz.

7. Lower fuel
mileage

8. If the engine is not
burning fuel
properly, then it will
need more fuel to
do the same task.

9. When the ignition
coil malfunctions, it
will send more fuel
than it required.

10. Oil leaks

11. When a huge
amount of current
and charge being
transformed inside
the ignition coil
may lead to heat
dissipation.

12. If the coil is broken,
then this can lead
to overheating and
eventually crack the
hosing.

13. Engine misfiring

14. When the ignition
coil is failing, it often
leads to pistons
misfiring or simply
not firing at all.

15. If the ignition coil is
bad in Mercedes-
Benz, then you will
notice several
problems such as:
• Strange noises
• Poor response
• Engine jerks or vibrates
when idling
• Car shutting down
altogether

16. Illuminated check
engine light

17. The illuminated
check engine light
also indicates the
broken ignition coil.

18. In such a situation,
get down your
Mercedes-Benz to a
mechanic to perform
the OBD –II check.

19. Fails to start

20. When the ignition
coil is failed, your
car fails to start
when you try to turn
the key in the
ignition.

21. In this case, the
spark plugs are
unable to receive the
charge they need
and the engine will
fail.

22. Conclusion

23. Like other parts of
the Mercedes-Benz,
the ignition coil will
also degrade
eventually.

24. Get down your
vehicle to a
professional service
center to replace the
ignition coil.
