In the affected vehicles, an auxiliary water pump, which supports cooling of the turbocharger, can malfunction because of a defective circuit board. In certain situations, this circuit board can overheat and smolder the water pump, which may lead to an engine compartment fire or vehicle fire.
The recall is expected to begin in November. BMW dealerships will replace the pump free of charge. Owners can call BMW at 800-525-7417 or NHTSA’s vehicle safety hotline at 888-327-4236 for more info.
