Engine backfiring in BMWs can result from incorrect engine timing, a damaged distributor cap, or an engine running too rich. Incorrect timing leads to late ignition cycles, while a damaged distributor cap can cause sparks in the wrong cylinder. An overly rich fuel-to-air mixture can also result in explosive burns that trigger backfiring, necessitating prompt repair.

6. Incorrect Engine Timing

7. This is a primary cause
behind engine misfires in
BMW.

8. This is also known as the
retarded timing of
BMW.

9. The fuel-compression-
ignition-exhaust is not in
sync with the bottom end.

10. This causes the ignition
cycle to begin late which
leads to misfires.

11. Damaged Distributor Cap

12. Older model BMWs are
equipped with a
distributor cap.

13. These distributor caps
send electrical signals to
the spark plugs.

14. If the cap is damaged,
then moisture can get in
& cause sparks in the
wrong cylinder.

15. Whenever an incorrect
cylinder fires, you will
experience an engine
backfire.

16. Engine Running Too Rich

17. It is caused when the
engine is being supplied
with more fuel than
necessary.

18. The rich fuel to air
mixture can be caused by
a dirty air filter.

19. The too much fuel creates
an explosive fast-burning
flame.

20. When the exhaust valve
opens, then this explosive
burn causes engine to
backfire.

21. Conclusion

22. Engine backfire issue
needs to be immediately
taken care of.

23. Take your BMW to an
experienced repair shop
to fix the issue.
