AFTER STARTING THE CAR AND MOVING A SHORT DISTANCE, THE DASH DISPLAY SHOWED MULTIPLE WARNINGS REGARDING THE EXTERIOR LIGHTS. APPROXIMATELY 12 EXTERIOR LIGHTS HAD ALL GONE OUT AT ONCE. AFTER SOME RESEARCH ON THE ISSUE I CHECKED THE FUSE BOX IN THE ENGINE BAY AND FUSE F16 (30A) HAD MELTED WITH RESIDUE ON THE CONTACT BUT NOT FAILED. THE CONTACT ON THE FUSE BOX ALSO HAD RESIDUE AND THE SURROUNDING PLASTIC WAS MELTED AS WELL. THE SAME EXACT ISSUE OCCURRED ON MY 2009-2011 VW TIGUAN AND A RECALL WAS ISSUED (NHTSA CAMPAIGN NUMBER: 13V569000 AND VW RECALL NUMBER: 97Z9/2V). THE PART RECALLED IN THE TIGUAN IS THE SAME EXACT PART USED IN THE 2012 AUDI A3 (PART #: 1K0937125D). AOA SHOULD RECALL THE PART AS WAS DONE BY VW. THERE ARE MULTIPLE SAFETY ISSUES THAT ARE CAUSED BY THIS FAILURE SUCH AS LOSS OF EXTERIOR LIGHTING WHILE DRIVING AT NIGHT AND POSSIBILITY OF FIRE CAUSED BY OVERHEATING. ATTACHED ARE PHOTOS OF THE MELTED FUSE AND FUSE BOX AS WELL AS THE VW TIGUAN RECALL NOTICE. *TR
AFTER STARTING THE CAR AND DRIVING ABOUT 50 FEET, THE VEHICLE DRIVER DISPLAY SCREEN SIGNALED THAT MULTIPLE EXTERIOR LIGHTS HAD FAILED SIMULTANEOUSLY. SENSING THAT MULTIPLE LIGHT BULBS WOULD NOT FAIL AT ONCE UNLESS THERE WAS A LARGER ELECTRICAL PROBLEM, I PROMPTLY MADE AN APPOINTMENT AT THE LOCAL AUDI SERVICE CENTER THE NEXT DAY.…

AFTER STARTING THE CAR AND DRIVING ABOUT 50 FEET, THE VEHICLE DRIVER DISPLAY SCREEN SIGNALED THAT MULTIPLE EXTERIOR LIGHTS HAD FAILED SIMULTANEOUSLY. SENSING THAT MULTIPLE LIGHT BULBS WOULD NOT FAIL AT ONCE UNLESS THERE WAS A LARGER ELECTRICAL PROBLEM, I PROMPTLY MADE AN APPOINTMENT AT THE LOCAL AUDI SERVICE CENTER THE NEXT DAY. AFTER DIAGNOSIS BY AUDI TECHNICIANS, I LEARNED THAT THE FUSE BOX UNDER THE HOOD HAD MELTED DUE TO OVERLOAD OF CIRCUITS OR WIRING IN THE BOX. HAD I NOT TAKEN THE CAR IN FOR REPAIR, THE OVERLOAD COULD HAVE CAUSED A FIRE IN THE ENGINE BAY. I RESEARCHED THIS PROBLEM ONLINE AND FOUND OTHER OCCURRENCES EXPERIENCED BY VOLKSWAGEN/AUDI VEHICLE DRIVERS WITH THE SAME SYMPTOMS. PLEASE ADD THIS INCIDENT TO YOUR RECORD OF CASES. THANK YOU. *TR
WHILE DRIVING MY LIGHTS WOULD RANDOMLY GO OUT BOTH DURING DAY AND NIGHT. DASH WARNING WOULD BE BULB OUT NEEDING REPLACING BUT NOTHING WAS EVER WRONG WITH THE BULBS OR TURN SIGNALS.

WHILE DRIVING MY LIGHTS WOULD RANDOMLY GO OUT BOTH DURING DAY AND NIGHT. DASH WARNING WOULD BE BULB OUT NEEDING REPLACING BUT NOTHING WAS EVER WRONG WITH THE BULBS OR TURN SIGNALS. ISSUE WAS INTERMITTENT AND WARNING WOULD GO AWAY ON IT'S OWN OR AFTER CAR RESTARTED. LATER WHEN DASH WARNING CAME ON AND STAYED ON I TOOK IT INTO SERVICE WHICH LATER WAS DIAGNOSED TO BE A MELTED FUSE BOX PANEL ON F16 & F17. BOTH FUSE SLOTS WERE MELTED ALONG WITH F16 FUSE (15AMP) AND BURN MARKS ALONG THE HOUSING. THE DEALERSHIP REPAIRED IT BUT WOULD NOT COVER THE REPAIR UNDER WARRANTY OR ACKNOWLEDGE THE KNOWN ISSUE WHICH WAS RECALLED ON VW SIDE BUT NOT BY AUDI. THE FUSEBOX IS 1K0937125D. AUDI OF AMERICA SHOULD HAVE HAD THIS COVERED UNDER WARRANTY FROM WHEN THE SYMPTOMS STARTED, OR RECALLED THE PART AS WAS DONE ON VW SIDE. THIS IS A SAFETY ISSUE DUE TO LIGHTS WHILE DRIVING AT NIGHT, AND POTENTIAL FIRE ISSUE WITH THE MELTING OF PANEL AND FUSE.
WHILE DRIVING AT 50MPH, AN MIL INDICATOR ILLUMINATED ON THE DASHBOARD. A CONSISTENT CHANGE IN POWER OR DRIVABILITY WAS NOT EXPERIENCED IMMEDIATELY, BUT INTERMITTENT MOMENTS OF SLIGHT POWER LOSS WERE NOTICED (1 SECOND DROP IN POWER) DURING BOTH CRUISE OR ACCELERATION DURING THE REMAINING DRIVE HOME AFTER THE LIGHT ILLUMINATED.

WHILE DRIVING AT 50MPH, AN MIL INDICATOR ILLUMINATED ON THE DASHBOARD. A CONSISTENT CHANGE IN POWER OR DRIVABILITY WAS NOT EXPERIENCED IMMEDIATELY, BUT INTERMITTENT MOMENTS OF SLIGHT POWER LOSS WERE NOTICED (1 SECOND DROP IN POWER) DURING BOTH CRUISE OR ACCELERATION DURING THE REMAINING DRIVE HOME AFTER THE LIGHT ILLUMINATED. WHEN I ARRIVED HOME, I INSPECTED THE ENGINE FOR ANY OBVIOUS SIGNS SUCH AS DISCONNECTED OR LOOSE ELECTRICAL CONNECTIONS, OIL LEVEL, ETC. I DID FIND A POOL OF OIL ON TOP OF THE CYLINDER HEAD POOLING AROUND THE INJECTOR PORTS. THIS CAUSED ME GREAT CONCERN, SO ON JULY 3, I DROVE THE VEHICLE TO THE NEAREST AUDI DEALERSHIP. AFTER TWO DAYS, AN ASST. SERVICE MANAGER CALLED ME TO PRESENT A DIAGNOSIS THAT THE EXHAUST FLAP, ASSOCIATED WITH THE EMISSIONS SYSTEM, REQUIRED REPLACEMENT AND THAT A TECHNICAL SERVICE BULLETIN WAS ISSUED BY AUDI FOR THIS SPECIFIC PROBLEM. THE OIL POOLING ON TOP OF THE ENGINE WAS ATTRIBUTED TO REMNANTS FROM A PREVIOUS SERVICE VISIT TO THIS SAME DEALERSHIP. THE ASST. SERVICE MANAGER REPORTED THAT THE OIL WAS CLEANED FROM TOP OF ENGINE AND THEN THE VEHICLE WAS TEST DRIVEN WITH NO PERCEIVABLE OIL DISCHARGE OCCURRING AFTERWARD. MY CONCERN IS THAT THE EXHAUST FLAP IS AN ISSUE FOR ALL VEHICLES WITH THE CBEA ENGINE TYPE AND SHOULD BE REPLACED BY AUDI DUE TO FAULTY QUALITY. BEING AN EMISSIONS COMPONENT, THE QUALITY OF THE EMISSIONS CONTROL MUST BE IMPACTED OR AT LEAST DETRIMENTAL TO OTHER COMPONENTS IN THE SYSTEM WHICH REGULATE THE EMISSION OF NOXIOUS GREENHOUSE GASES. I AM CONCERNED THAT THE DRIVABILITY COULD SUFFER TO A GREATER EXTENT OVERTIME IF THE EMISSIONS SYSTEM BECOMES COMPROMISED BY THIS FAULTY EQUIPMENT. MY HOPE IS THAT AUDI WILL OPEN A CAMPAIGN TO REPLACE THIS COMPONENT FOR LOYAL CUSTOMERS AND PROLONG THE LIFE OF THE TDI CLEAN DIESEL AND ITS REMARKABLE REDUCED EMISSIONS TECHNOLOGY.

2PE11023 · Diesel Fuel Injector Line Leakage
Opened Aug 2, 2011 · Closed Dec 2, 2011
Status: closed (inferred from source dates) · Fuel System, Diesel
By letter dated October 3, 2011, Volkswagen Group of America, Inc. (VW) notified the National Highway Traffic Safety Administration (NHTSA) 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 (NHTSA 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 NHTSA 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.
EA11003 · High-Pressure Fuel Pump Failure
Opened Feb 7, 2011 · Closed Mar 27, 2015
Status: closed (inferred from source dates) · Fuel System, Diesel; Fuel System, Other:delivery:fuel Pump
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 NHTSA 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.
