What is wrong

Volkswagen is recalling certain model 2009-2012 jetta and jetta sportwagen vehicles, manufactured from may 2008 through september 2011, model year 2010-2012 volkswagen golf vehicles, manufactured from may 2009 through september 2011, and model year 2010-2012 audi a3 vehicles, manufactured from september 2009 through september 2011, that are equipped with a 2.0l tdi common rail diesel engine/clean diesel engine. The fuel injection pulses could coincide with the natural frequency of the injector line #2, in specific load and RPM conditions. This resonance creates additional stress in the fuel line.

Risk

Due to the resonance condition, injector line number 2 could develop small cracks which could lead to fuel leakage. Leaking fuel in the presence of an ignition source, may lead to a fire.

Remedy

Volkswagen will install an improved fuel injector line for the number 2 cylinder on certain vehicles and will install vibration dampers on all of the injector lines. Volkswagen and audi will notify owners to have the vehicles repaired free of charge. The safety recall is expected to begin during november 2011. Owners may contact volkswagen at 1‑800‑822‑8987.

Recall number 11V490000 · Recall details

In August 2015, VW launched Safety Recall 15V‑483 to address the loss of the protection provided by the front driver air bag in several models due to the failure of the clock spring. VW’s recall indicated that debris entry into the steering wheel hub can result in the contamination and ultimately failure of the clock spring in 2010-2014 MY CC, Eos, GTI, Golf, Jetta, Jetta Sportwagen, Passat, and Tiguan models. The contamination of the clock spring by debris, such as human hair, can cause the flat ribbon cable to tear. This results in the loss of the electrical connection to the front driver air bag and any steering wheel mounted controls. The clock spring is designed so that the flat cable inside will break with minimum force to prevent it from impeding movement of the steering wheel. The loss of the electrical connection to the front driver air bag results in the immediate illumination of the air bag warning light and prevents the deployment of the front driver air bag in a collision of sufficient severity. A torn clock spring also causes audible grinding noises from the area of the steering wheel/driver air bag or steering column while steering. The failure of the clock spring does not impair vehicle control or drivability (steering, brakes, acceleration). In November 2017, the Office of Defects Investigation (ODI) opened Recall Query RQ17009 after receiving complaints that alleged the failure of the clock spring in the subject models. While the majority of these complaints involved vehicles excluded from the original recall, several complaints involved vehicles that had received the remedy for Recall 15V‑483. On April 18, 2018, ODI upgraded the investigation to Engineering Analysis EA18003 after receiving additional complaints concerning the recall remedy and scope of Recall 15V‑483. During the investigation, VW identified certain 2015-2018 MY vehicles that share a common steering wheel clock spring with the vehicles covered under Recall 15V‑483. VW began using a different clock spring design starting with the 2019 MY Jetta. This new part is not compatible with previous model years due to the communication properties between the clock spring and the vehicle, including the air bag control module. In October 2018, VW released Warranty Extensions AWA-18-18 and VWP-18-11, which established a 15-year, unlimited mileage coverage for the Steering Wheel Clock Spring for vehicles included in the scope of Recall 15V‑483. For certain 2010-2018 MY vehicles outside of the recall scope, a 10-year, 120,000-mile coverage was given. Vehicles repaired under these warranty extensions receive replacement clock springs at no charge to the consumer. In early 2023, VW updated AWA-18-18 (now AWA-23-01) and VWP-18-11 to upgrade certain vehicles and model years from the 10-year, 120,000-mile coverage to the 15-year, unlimited mileage coverage option. These warranty extensions cover vehicles with recall remedy failures as well as vehicles outside of the Recall 15V‑483 scope that exhibited similar failures. In view of the circumstances, including the high detectability of the subject failure and warranty extensions issued by VW, ODI is closing this Engineering Analysis. the federal safety agency reserves the right to take additional action if warranted by future circumstances.

EA18003

By letter dated October 3, 2011, Volkswagen Group of America, Inc. (VW) notified the federal safety agency that it will conduct a safety recall to address a defect in approximately 168,275 model year (MY) 2009-2012 Volkswagen Jetta, Jetta Sportwagen, Golf, and Audi A3 vehicles equipped with the 2.0L TDI Common Rail Clean Diesel engine (the federal safety agency Recall No. 11V‑490).The recalled Jetta and Jetta Sportwagen vehicles were built from May 2008 through September 2011, the Golf vehicles were built from May 2009 through September 2011, and the Audi A3 vehicles were built from September 2009 through September 2011.According to Volkswagen, in U.S. applications of the above cited TDI vehicles including engine codes CJAA and CBEA, the fuel injection pulses could coincide with the natural frequency of the injector line #2 in specific load and RPM conditions.This resonance creates additional stress on the fuel line which a small number of parts (based on the statistic spread of line strength) cannot withstand over its lifetime.As a contributing factor, VW indicated that a supplier used tube material with scratch marks from a grinding process during certain production periods.Lines manufactured in these periods were installed in vehicles produced in the following 10 months:December 2008, January-February 2009, October 2009, March-April 2010 and September-December 2010.Injector lines using this material exhibit a significantly higher failure rate.Dealers will replace injector line #2 in all vehicles built in these months.In addition, as a precautionary measure, all recalled vehicles will have vibration dampers installed on all four fuel injector lines.Analysis of the federal safety agency complaints, VW complaints, VW field reports and warranty claims found allegations of injector line leakage in 443 subject vehicles.The leaking line was not identified in 62 of the vehicles.For the 381 that did provide information about which injector lines were leaking and/or replaced, 358 (94%) involved an injector line #2 leak/repair.Almost three-quarters of the injector line #2 leak/repair incident vehicles were built in the 10 months identified by VW, which accounted for approximately one-quarter of the recalled vehicles.The failure rate for injector line #2 in vehicles built in the 10 months affected by the supplier line scratching issue is 6.0 incidents per thousand vehicles (IPTV).The failure rate for injector line #2 in other production months of recalled vehicles is 0.8 IPTV.The leak/repair rates for the other injector lines are all well under 1 IPTV.The action taken by Volkswagen is sufficient to resolve the issues raised by this investigation. The agency will continue to monitor this issue and reserves the right to take further action if warranted by the circumstances. Accordingly, this investigation is closed.

The Office of Defects Investgation (ODI) opened EA11-003 on February 7, 2011, based on 160 complaints to ODI and Volkswagen involving high pressure fuel pump (HPFP) failures in model year (MY) 2009 through 2010 Volkswagen Jetta and Golf and Audi A3 TDI vehicles and questions regarding fuel sample results provided by Volkswagen as part of its response to PE10-034.During EA11-003, ODI analyzed design information, field experience and test data for MY 2009 through 2012 Volkswagen Jetta, Golf and Touareg and Audi A3 and Q7 vehicles equipped with TDI engines. Volkswagen has not identified any design or manufacturing defects in the subject TDI Clean Diesel pumps and has stated that the subject pumps were designed, tested and approved for use in the United States market, with substantial design margins for fuels that are out of specification.Volkswagen believes that misfueling with gasoline is the primary cause of HPFP drivetrain failures in the field.Only the Q7 vehicles were built with misfuel protection devices.In May 2013 Volkswagen initiated a service campaign to install misfuel protection devices in all MY 2009 through 2012 Jetta, Golf and A3 vehicles.Volkswagen implemented misfuel protection devices in all of the subject models beginning in MY 2013. ODI?s analysis of HPFP drivetrain failure incidents indicates that most failures do not result in engine stall while driving and, when pump drivetrain failure does result in stall while driving, it is usually preceded by numerous warning symptoms (e.g., glow plug warning lamp, chime, limp mode, and driveability symptoms).The failure data for the subject vehicles show relatively low stalling rates (less than one percent at three years in service) for each of the pump designs used in the subject vehicles.There have been no reports of crashes, injuries or fatalities related to the alleged defect. Based on these facts, this investigation is closed.The closing of this investigation does not constitute a finding by the federal safety agency that a safety-related defect does not exist.The agency will continue to monitor complaints and other information relating to the alleged defect in the subject vehicles and take further action in the future if warranted.For additional information, see the closing report in the document file for EA11-003.

The Office of Defects Investigation (ODI) and Volkswagen (VW) have received a total of 160 complaints and field reports alleging incidents of engine stall and/or loss of power that appear to be related to high pressure fuel pump (HPFP) failures in certain model year (MY) 2009 through 2010 Volkswagen Jetta and MY 2010 Volkswagen Golf and Audi A3 vehicles equipped with TDI clean diesel engines.Approximately half of the reports indicate that the failure resulted in an engine stall incident, with many of these alleging stall incidents at highway speeds in traffic with no restart.There has been one minor crash alleged to have resulted from HPFP failure in the subject vehicles.In response to ODI's information request for PE10-034, VW indicated that it had found no defect related to motor vehicle safety with relation to the TDI Clean Diesel fuel system at issue in this investigation and attributed problems with HPFP failure to operation with gasoline contaminated diesel fuel.Volkswagen stated that even a small amount of gasoline in the diesel fuel may disrupt the necessary lubrication required and may cause the HPFP to fail.In response to concerns that fuel contamination was the major cause of HPFP and related fuel system failures, VW issued a Technical Service Bulletin in May 2010 (VW TB V011011 2023624 and Audi TB A011008 2023360-1), with instructions to inspect the diesel fuel for vehicles requiring fuel system service that have symptoms associated with HPFP failure.The bulletin states that fuel system damage incurred by use of fuel not complying to ASTM-D-975 Grade 2 S15 (B5 or less biodiesel content) standards will not be covered under warranty. Volkswagen also provided information about 121 mis-fueling incidents reportedly acknowledged by consumers or dealers and test results for about 50 diesel fuel samples taken from complaint vehicles in late-August through early-October 2010.The mis-fueling incidents include about 20 reports involving incorrect fueling by dealer sales or service personnel and generally report symptoms such as rough running, stalling and/or no start within a few miles of refueling the vehicle with gasoline.Volkswagen indicated that the testing of fuel samples from complaint vehicles found that nearly 90 percent contained high amounts of gasoline.Volkswagen implemented design changes for the HPFP in May 2008, September 2009 and November 2010 to improve the robustness of the pump when used with poor quality fuel.ODI analysis of HPFP failures identified from all sources shows failure rates of 0.53% for MY 2009 vehicles and 0.11% for MY 2010 vehicles.This investigation has been upgraded to an Engineering Analysis (EA11-003) to continue to investigate the issues with mis-fueling and HPFP design identified during the Preliminary Evaluation.
