Steering Idler Arm problems of the 2010 BMW 335

While driving on a divided highway at 60 mph, I experienced a sudden loss of power steering assist. Steering became very stiff and there was a strong burnt rubber smell emanating from the engine compartment. I drove about 6 miles further and parked the car in my driveway. I also noticed the battery symbol illuminated with warning message �charging malfunction. � I had the car towed to the BMW dealership for repairs. I believe this is an identical issue that resulted in the BMW recall campaign no. 12v-550: engine belt idler pulley bolt for the x5. I am concerned because I believe the engine in my 335d is identical to the diesel engine in the x5 recall and believe the 335d should be included in this recall. I will be contacting BMW corporate headquarters about my concern.
