2. The check engine light illuminates
whenever there is something wrong
with your Audi.

3. There are various issues that cause
the engine warning light to come
on & needs to be fixed quickly.

4. Here are the 5 reasons behind the
illumination of the check engine
light in your Audi.

5. Malfunctioning Oxygen
Sensor

6. The oxygen sensor is
responsible for monitoring the
amount of unburnt oxygen
present in the exhaust system.

7. The data collected by the sensor is
used to regulate the mixture of air &
fuel that helps in the combustion
process.

8. When the oxygen sensor of
your high-end vehicle goes bad
it leads to the illumination of
the check engine light.

9. Bad Catalytic Converter

10. The catalytic converter converts
the toxic carbon monoxide
produced during the
combustion process into
carbon dioxide.

11. Now, the catalytic converter is
an expensive part of your car and
you need to replace it when it
fails.

12. The illumination of the check engine light is often
caused due to a bad catalytic converter in your vehicle.

13. Issues With the Spark Plugs

14. Issues with the functioning of the spark plugs
are also very difficult to diagnose as there are
multiple spark plugs in your car.

15. Now, failure of any of these spark plugs is
going to illuminate the warning light
on the dashboard of your car.

16. Faulty spark plugs can even lead to
engine misfires and hesitation when
you try to accelerate the car.

17. Vacuum Leak

18. The vacuum system helps in the functioning
of the brake booster and also limits the emission
from your car.

19. Most of the time vacuum leak in your car is the
prime culprit behind the illumination of the
engine warning light.

20. The vacuum hoses in your car need to be
inspected for the detection of a leak.

21. Faulty EGR Valve

22. The EGR valve assists in controlling
the emissions by limiting the amount of
nitrogen oxide coming out from the
engine.

23. The EGR valve helps in rerouting the exhaust gas back into
the combustion chamber which helps in efficient
combustion.

24. As the car picks up miles, the
EGR valve gets clogged & this
leads to the illumination of
the check engine light.

25. Conclusion

26. These are some of the leading causes behind the illumination of
the check engine light in your Audi.

27. Take your Audi to a certified repair shop for getting it diagnosed
and fixed immediately.
