On some models — built between Oct. 1, 2008, and June 12, 2009 — the fuel filter heater, which heats up the diesel fuel during cold winter driving, can experience an electrical overload that can cause the heater to stay on permanently, even when the vehicle is parked and the ignition is off. If this happens, the vehicle’s battery could drain until it’s dead or, in rare cases, the unit could overheat and eventually cause a fire.
BMW will notify owners, and dealers will replace the fuel filter heater for free. The recall will begin in October. Owners can call BMW at 800-525-7417 or NHTSA’s vehicle safety hotline at 888-327-4236 for more info.
