Summary
In July 2010, the Agency opened PE10-027 to investigate allegations of coil on plug (COP) ignition coil fires in MY2002-2003 VW Passat vehicles.The investigation was upgraded in January 2011 to include all MY2001-2007 4-cylinder VW Passat, gasoline, turbo-charged vehicles.Based on the analysis of VW's response, and including ODI's consumer complaints, ODI has since identified 135 unique engine fire reports attributable to the COP coils.After further review of the details as contained in each report, ODI determined that 43 of the 135 fire reports were actual fire/flame incidents, 83 fire reports were thermal events (smoke, spark, heat or wire melt), and another 9 fire reports were undetermined in severity due to the lack of information.These COP coil fires were characterized as initiated from within the COP coil circuit located at the top of the engine block and below the plastic engine cover.The fires observed were contained in the engine compartment and did not reach into the passenger compartment in contrast to those caused by an overheated catalytic converter examined in ODI-s investigation in 2007 and 2008.There were no reports of crashes or personal injury in this examination.A safety-related defect has not been identified at this time and further use of agency resources does not appear to be warranted.Accordingly, this investigation is closed.The closing of this investigation does not constitute a finding by NHTSA that a safety-related defect does not exist.The agency will monitor this issue and reserves the right to take further action if warranted by the circumstancesSee the Closing Report for additional details.
