1. Drivetrain
Malfunction On
BMW: What Does It
Mean?

2. The torque
output of your
BMW's drivetrain
has dropped
significantly.

3. Possibly due to a
fault in the engine
or transmission.

4. This discussion will
help you to find out
the exact reason. So,
please go through it.

5. But, before
moving on, let's
find out what
drivetrain
actually means.

6. A Brief Introduction to the
Drivetrain

7. Drivetrain is not a part.

8. Major parts that make
up the drivetrain are;
The transmission
Driveshaft
Axles

9. It’s the drivetrain that transfers
engine power to the wheels.

10. If the torque output of
the drivetrain declines,
the ECU will display;

11. Drivetrain malfunction:
Drive moderately.
Maximum drivetrain
output not available.
Consult service center.

12. Here’s Why BMW Displays
‘Drivetrain malfunction’
message

13. Spark plug failure

14. Spark plugs assist the engine in
the combustion process.

15. If one of them
stops working,
the power output
of the engine will
reduce.

16. This may prompt the ECM or
ECU to activate the 'Drivetrain
malfunction' message.

17. Failing fuel injectors

18. Fuel injectors, if
clogged, may not keep
up with the fuel
demand of the engine.

19. Reduced engine
performance due to
bad fuel injectors can
activate;

20. Drivetrain malfunction’ message
on the dash of a BMW.

21. Damaged catalytic
converter

22. A faulty catalytic
converter can cause
breathing difficulties
for the engine.

23. This may adversely affect the
torque output of the engine.

24. Decreased torque
output due to a faulty
catalytic converter
may activate;

25. Drivetrain malfunction’
message on the dash
of a BMW.

26. Bad high-pressure fuel pump
or HPFP

27. It is HPFP which
helps the fuel
injector in spraying
atomized fuel in
the cylinder.

28. Issues with such a critical part
can destabilize the air-to-fuel
ratio in the engine.

29. This may activate the
'Drivetrain malfunction'
warning message.

30. Ignoring an error message like
'Drivetrain malfunction’ can cost
you money.

31. Therefore, if your BMW
displays a warning like
this, call a nearby car
repair shop.
