One problem related to crankcase (pcv) has been reported for the 2009 BMW 3 Series. The most recently reported issues are listed below.
In November 2017 I received two (2) recall notices for my 2009 BMW 328i. I was advised that the blower motor wiring (recall campaign # 17v-676) and pcv valve heater (recall campaign # 17v-676) were defective. I was further notified that no remedy for either defect was available at that time. It is now September 2018. I have contacted BMW and been advised that at this time a remedy remains unavailable. I am considering selling or trading in my vehicle but because this recall has not yet been completed my resale price may be lowered. If two (2) recall repairs have not been performed 10 months after a recall notice has been issued, why bother issuing the recall notice in November 2017 if it is for any other purpose than bureaucratic paper shuffling for BMW to claim to the NHTSA that BMW is going to fix a defect while actually doing nothing to remedy the defect?.
