BMW of North America is recalling 740,561 model year 2008-2011 128i and 2007-2011 328i, 328xi, 328i xDrive, 525i, 525xi, 528i, 528xi, 530i, 530xi, X3 3.0si, X3 xDrive30i, X5 xDrive30i, Z4 3.0i, Z4 3.0si and Z4 sDrive30i vehicles.
The heater for the positive crankcase ventilation (PCV) valve may short circuit, causing the parts within the PCV valve to melt, increasing the risk of a fire -- even when the vehicle is not in use.
What to do
BMW will notify owners, and dealers will replace the PCV valve heater, free of charge.
The recall is expected to begin December 18, 2017.
Owners may contact BMW customer service at 1-800-525-7417.
