Failure of the component
WARNING: This page does not describe the selected car, but rather 7 other vehicles, including the 2017 BMW X3, 2016 BMW X3, 2015 BMW X3, 2014 BMW X3, and 2013 BMW X3. However, it is still accessible from the selected car via links, so may be relevant.
If the electric fan fails, the following behavior is to be expected:
- Fault entry in the engine control unit
- Power reduction (if engine overheated)
- Check Control message in the instrument panel
- Damage to thermally critical components in the car front end after stopping the engine (post-heating of the engine)
General notes
The electronic evaluation unit runs an internal fault diagnosis for critical states. If a fault is detected, operation is maintained as far as possible.
If activation by pulse width modulation fails, the electric fan is activated in the emergency mode with a fixed pulse duty factor. We can assume no liability for printing errors or inaccuracies in this information and reserve the right to introduce technical modifications at any time.
