BMW will be asking approximately nine thousand sedan, crossover, and roadster owners to return their vehicles to a manufacturer repair facility for a safety defect that could result in the loss of oil supply to the vacuum pump. Due to an insufficient interference fit, the seal disk in the camshaft could move during engine operation, potentially restricting or blocking the oil supply holes. Over time, the pump could fail resulting in loss of power assist braking and an increased chance of an accident. (Even with loss of assist, the service brake control is able to stop the vehicle because affected vehicles meet the applicable FMVSS pertaining to conditions in which there is a loss of power assist braking.)
The vehicles affected by this recall include:
BMW will be notifying owners to take their vehicles to their nearest dealers who will install a locking ring in the camshaft to retain the camshaft seal disk in the proper location. Owners wanting more information about the problem can contact BMW customer service at 1-800-525-7417. The NHTSA campaign number is 14V-627. (Note: This recall is an expansion of recall 13V-454.)
