On the 29,800 diesel X5 models affected by the recall, the idler pulley bolt could back out and/or break, which would cause a loss of power steering. To repair the problem, BMW will begin notifying owners next month, and dealers will replace the bolts. For owners of the 2009 X5 xDrive35d, this comes a little more than a year after 2,120 models were recalled for a faulty fuel pre-heater.
