If you reside in North America and happen to own a 3-Series, 5-Series or Z4, then this recall notification concerns you. According to the data released by the National Highway Traffic Safety Administration (NHTSA), certain units of the aforementioned models are included in a safety campaign that affects 184,505 units.
The defective part is the heater for the positive crankcase ventilation (PCV) valve, which may short circuit due to manufacturing irregularities. Moisture can degrade the plastic components, leading to overheating which, in the presence of fuel, could start a fire in the engine compartment even when the vehicle is stationary and the engine is turned off.
The recall includes certain 325i, 325xi, 330i and 330xi E90 Sedans, made between February 1, 2006, and August 30, 2006, as well as the 325xi E91 Sports Wagon assembled for one week until August 30, 2006. The 525i, 525xi, 530i and 530xi E60 Sedans, manufactured from February 4, 2005, to February 27, 2006, along with the 530xi E61 Sports Wagon produced from April 1, 2005, until February 25, 2006, are also affected. The campaign includes the Z4 3.0i and 3.0si E85 Roadsters and Z4 3.0si E86 Coupes too, whose production dates span between April 28, 2005, and September 29, 2006, and April 18 and September 27, 2006, respectively.
BMW’s technicians will inspect and replace the PCV valve heater free of charge. If necessary, other components will be replaced as well.
Owners should expect to hear from the automaker by First Class mail, instructing them to schedule an appointment with an authorized center. The recall is estimated to begin on May 28.
