Fuel system reportsComplaints are reports submitted to NHTSA by owners and drivers. NHTSA does not verify most reports before publishing them, and a complaint does not establish that a defect exists. Volume is influenced by how many of a vehicle were sold, how long it has been on the road, and how much attention an issue has received.

Good morning, For the past couple of weeks, I've been getting the run around on whether the issue I'm having with my vehicle is an active recall. I recently took my vehicle to Eurocode Tuning (Torrance, CA), and the mechanic instructed me to take my vehicle to the dealer because the issue I am currently experiencing (fuel leak in the injection system) is listed as a recall. I contacted the Audi dealership in Long Beach CA via phone at (562)610-4000, the service representative stated that he found no active recall on my vehicle. Once again contacted Eurocode Tuning and they stated to have them run a diagnostic on the vehicle and they will see its the fuel leak in the injection system. And they are required by law to fix the recall. The following morning I took my vehicle into McKenna Audi ( Norwalk, CA) and one of the service representatives reiterates that my vehicle has no active recall. I stated that I was well aware of that, however, the issue I was having was listed as a recall on the web and I was informed by the repair shop as well. I proceeded to show him the information I got offline and my failed smog that was done on my vehicle. He proceeded to show me the breakdown on his computer that it was no active recall and the only thing that they were looking into was issues regarding the turbo. He stated what I was talking about was an extended warranty and my vehicle is well past that warrant. He then proceeded to say if a diagnostic is done on my vehicle I will be responsible to pay it and any repair done on my vehicle. So I walked out and decided to contact you. I am just trying to determine whether my vehicle could be repaired under the recall. I'm extremely frustrated and concerned for my safety because the recall did state the risk of a fire. Sincerely a confused, frustrated Audi owner [XXX] [XXX] INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

The contact owns a 2012 Audi A6. The contact stated while pulling out of the driveway, he smelled an abnormal fuel odor. The contact stated that the fuel odor became stronger while driving 65 MPH. There was no warning light illuminated. The contact stated that he pulled into a parking lot and opened the hood. The contact stated that he noticed that the fuel odor was coming from the engine. The vehicle was towed to an independent mechanic, where the check engine warning light illuminated. The mechanic determined that the check engine warning light had illuminated due to low pressure on the fuel rail, and the contact was informed that the supercharger needed to be removed for a more thorough inspection of the vehicle. The dealer was notified of the failure and informed the contact that the VIN was not included in a recall. The vehicle was not diagnosed nor repaired. The manufacturer was notified of the failure and informed the contact that the VIN was not included in NHTSA Campaign Number: 15V019000 (Fuel System, Gasoline). The manufacturer referred the contact to the NHTSA Hotline for assistance. The failure mileage was approximately 102,000.

I WAS DRIVING MY VEHICLE & NOTICED A FUEL SMELL. WHEN I GOT TO MY DESTINATION SHORTLY DOWN THE ROAD (~1 MILE) I INSPECTED MY ENGINE FOR THE SOURCE OF THE SMELL & FOUND FUEL LEAKING DOWN THE FRONT OF MY ENGINE FROM UNDER THE SUPERCHARGER. AFTER DISASSEMBLING THE TOP OF THE ENGINE I FOUND THE INJECTOR SUPPORTS TO BE THE OLD RECALLED PARTS (VERIFIED WITH ENGRAVED PART NUMBERS). I THEN CALLED THE AUDI DEALER THAT SUPPOSEDLY PERFORMED THE RECALL AND EXPLAINED THE SITUATION. THEY WERE VERY DISMISSIVE & ADVISED ME TO BRING THE VEHICLE IN. AFTER A FEW DAYS (4-7) THEY ADVISED ME THEY WOULD BE HAVING A REPRESENTATIVE FROM AUDI COME LOOK AT IT. I ATTEMPTED TO CONTACT AUDI MULTIPLE TIMES FOR A LOANER VEHICLE WITH NO RESPONSE. AFTER MULTIPLE DAYS OF REACHING OUT, I SHOWED UP TO THE DEALER & WAS GIVEN A LOANER VEHICLE DUE TO THE KINDNESS OF ANOTHER ADVISOR. THE RECALL: 24AP FUEL INJECTION SYSTEM LEAK. IN THE AUDI NOTIFICATION TO THE NHTSA THEY SPECIFICALLY CALL OUT THE INJECTOR SUPPORT BEING REVISED UNDER "DESCRIPTION OF REMEDY" STATING " IMPLEMENTATION OF REINFORCED FUEL RAIL RETAINING BRACKET" & RECEIVED AN UPDATED PART NUMBER WHICH CHANGED FROM 06D133036H TO 06D133036K. I AM WORRIED MORE PEOPLE COULD HAVE THIS POTENTIALLY FATAL ISSUE DUE TO THE LACK OF CRAFTSMANSHIP SHOWN AT THAT DEALER. THE ISSUE COULD BE SWIFTLY COVERED UP IF THE CUSTOMER DOES NOT HAVE THE MECHANICAL INCLINATION TO VERIFY CORRECT WORK IS BEING PERFORMED ON THEIR VEHICLE.

UPON STARTING MY VEHICLE I NOTICED EXTENDED CRANKING. UPON DRIVING THE VEHICLE I NOTICED A FUEL ODOR, INITIALLY I THOUGHT IT WAS THE OLDER VEHICLE DRIVING IN FRONT OF ME. AFTER DRIVING APPROXIMATELY 4 MILES I REALIZED IT WAS MY VEHICLE. I THEN DROVE MY VEHICLE BACK TO MY HOUSE, AND HAD IT TOWED TO AUDI OF ALBANY DUE TO RECALLS THAT WERE OPEN. UPON INSPECTION THEY PERFORMED RECALLS, BUT INFORMED ME THE RECALL FOR THE ENGINE FUEL RAILS WAS PERFORMED JUNE 2015. THEY THEN TOLD ME THEY NEEDED TO CHARGE LABOR TO INSPECT THE ISSUE, TO WHICH POINT I TOLD THEM I AM AN ASE MASTER MECHANIC, AND I WILL FIGURE THE ISSUE OUT MYSELF. I THEN HAD THE VEHICLE TOWED TO MY GARAGE, WHERE I TOOK IT APART FOLLOWING THE RECALL PROVIDED ON YOUR WEBSITE. UPON INSPECTION I VERIFIED THAT THE INJECTOR SUPPORTS (P/N 06D133036K) LISTED IN THE RECALL (CODE 24AP) WERE NEVER REPLACED. THE INJECTOR SUPPORTS I REMOVED FROM MY VEHICLE ARE (P/N 06D133036H). AUDI HAS HAD MY VEHICLE NOW FROM 21NOV2018 UNTIL THE PRESENT. THEY WILL NOT VERIFY THAT THOSE PARTS WERE SUPPOSED TO BE REPLACED DURING THE RECALL, AND ALSO IF ANY OTHER PARTS WERE NEVER REPLACED. THEY HAVE CONTACTED ME AND TOLD ME MY FUEL INJECTOR FAILED CAUSING THE FUEL LEAK, AND EVERYTHING WILL BE COVERED. I BELIEVE MY INJECTOR FAILED (IF THAT IS THE TRUTH) DUE TO THE NON REPLACED INJECTOR SUPPORTS. THE INCORRECT GEOMETRY OVER TIME WOULD CAUSE STRESS ON THE INJECTOR, AND FOR IT TO CRACK. I ALSO QUESTION IF ANY SEALS WERE TRUTHFULLY REPLACED, OR IF THE RECALL WAS DONE AT ALL. I ALSO FEAR THAT THIS ISSUE MAY HAVE OCCURRED TO OTHERS WHO HAD THE RECALL PERFORMED THERE (LANGAN AUDI), AND ARE NOT MECHANICALLY INCLINED ENOUGH TO DISASSEMBLE THERE ENGINE AND FUEL SYSTEMS. THIS PROBLEM COULD HAVE CAUSED A FIERY DEATH FOR ME AND MY FAMILY IN THE CAR IF I WASN'T INCLINED ENOUGH TO REALIZE THE PROBLEM IS MY CAR AND NOT OTHERS AROUND ME.
