BMW is recalling certain model year 2009-2010 X5 xDrive35d vehicles equipped with a diesel engine and manufactured from June 13, 2009, through November 9, 2009. The fuel filter heater, which is used for warming up the diesel fuel during vehicle operation at low outside temperatures, could experience an electrical overload condition and become permanently activated.
As a result, the fuel filter heater could remain activated even when the ignition is off and lead to a dead battery. The unit could also overheat, possibly resulting in a vehicle fire.
BMW will notify owners, and dealers will replace the fuel filter heater, free of charge. The safety recall is expected to begin in August 2013.
