The hazard
On certain vehicles equipped with the N52 6-cylinder engine, an electrical short could occur in the PCV valve heater due to manufacturing irregularities. If this occurs, the surrounding plastics could overheat, melt and potentially cause a fire, which could increase the risk of injury and/or damage to property. Correction: Dealers will replace the PCV valve heater.
