âThe PCV valve heater (positive crankcase ventilation heater) on my 2006 BMW 330xi failed and caused an engine bay electrical fire. This component is under an active BMW safety recall for fire risk. The failure happened suddenly while driving, with no prior warning lights or symptoms. Smoke began coming from the engine area, followed by visible flames. My safety was put at risk, and I immediately exited the vehicle. The vehicle became inoperable and was towed by the City of Chicago. The car has since been declared a total loss due to the fire. The vehicle is currently in the city impound and available for inspection upon request. The problem has not been inspected by a dealer yet because the vehicle was destroyed before I received the recall repair.â
