Among the several important sensors of the BMW X1, the oxygen sensor is located inside the exhaust pipe for observing the percentage of oxygen in the exhaust. It is also sending a signal to the ECU for adjusting the amount of fuel entering the engine. When the O2 sensor is failed, it will show some expensive problems in your BMW. So, go through the following slide to know about the signs of a faulty O2 sensor in the BMW X1.

1. HOW TO FIND A
FAULTY OXYGEN
SENSOR IN BMW X1 BY
DECATUR MECHANIC?

2. OXYGEN SENSOR LOCATED INSIDE THE
EXHAUST PIPE OBSERVES THE PERCENTAGE
OF OXYGEN IN THE EXHAUST.

3. O2 SENSORS ARE SENDING A SIGNAL TO THE
ECU TO ADJUST THE AMOUNT OF FUEL
ENTERING THE ENGINE.

4. FOR THE SMOOTH FUNCTIONING OF THE
ENGINE, THE O2 SENSOR OF THE BMW X1
NEEDS TO RUN PROPERLY.

5. CONSULT WITH A MECHANIC TO DETERMINE
THE O2 SENSOR PROBLEMS IN THE BMW X1.

6. THE FOLLOWING POINTS DEFINE THE SIGNS
OF FAULTY OXYGEN IN THE BMW X1.

7. POOR FUEL
MILEAGE

8. OXYGEN SENSORS BECOME LESS EFFECTIVE
AND COST YOU A HUGE AMOUNT OF MONEY
FOR REPAIR.

9. IF YOU NOTICE THE BMW IS CONSUMING
MORE FUEL THAN USUAL, THEN DIAGNOSE IT
BY A REPUTED MECHANIC.

10. ILLUMINATED
CHECK ENGINE
LIGHT

11. WHEN YOU WILL NOTICE FAILED O2 SENSOR
IN YOUR BMW X1, IT WILL ACTIVATE THE
CHECK ENGINE LIGHT.

12. CONSULT A MECHANIC TO GET THE ERROR
CODE OF CHECK ENGINE LIGHT AND
DETERMINE THE ROOT CAUSES BEHIND IT.

13. POOR ENGINE
PERFORMANCE

14. ENGINE PERFORMANCE IS REDUCED WHEN
THE NORMAL COMBUSTION PROCESS OF THE
ENGINE IS AFFECTED.

15. THE MAIN CAUSE BEHIND THE REDUCED
ENGINE PERFORMANCE IS FAILED OXYGEN
SENSOR.

16. FAIL EMISSION
TEST

17. DUE TO THE FAULTY OXYGEN SENSOR, YOUR
BMW X1 WILL ALSO FAIL THE EMISSION TEST.

18. THEREFORE, YOU WILL NOTICE AN
UNPLEASANT SMELL LIKE THE ROTTEN EGGS
FROM THE ENGINE.

19. ENGINE BEHAVE
ROUGHLY

20. THUS, THE FAILED OXYGEN SENSOR ALSO
MAKES THE ENGINE PRODUCE ROUGH
SOUNDS.

21. REASON BEHIND IS THE TOO LEAN OR TOO
RICH MIXTURE OF OXYGEN AND FUEL IN THE
ENGINE.

22. CONCLUSION

23. WHEN THE OXYGEN SENSOR IS REPLACED,
YOU WILL GET MANY BENEFITS IN BMW SUCH
AS:
• MAKE THE CAR ECO-FRIENDLY
• Reduce the emission of pollutants
• Enhance fuel mileage
• Increase engine performance

24. IF YOU ARE LIVING NEAR DECATUR, THEN
CONSULT AMECHANIC TO REPLACE THE BMW
X1 OXYGEN SENSOR.
