WHEN I FIRST GOT THE VEHICLE IT WOULD START WITH NO ISSUES AND NOW IT WONT START AN I CANT FIGURE OUT WHY AND NOT SURE IF THIS IS THE REASON I CANT THINK OF WHAT ELSE IT COULD BE IT ACTS LIKE ITS NOT GETTING ANY FUEL OR SOMETHING TO GET STARTED.
FILLED GAS TANK AND NOTICED FUEL LEAKING FROM TOP OF THE TANK TO THE GROUND NEAR THE INSIDE OF THE PASSENGER SIDE REAL WHEEL. FUEL STOPS LEAKING AFTER IT DROPS BELOW 3/4 FULL. TOOK THE CAR TO THE AUDI DEALERSHIP THINKING IT WAS FAILURE OF THE ROLLOVER/FILLER NECK VALVE RECALL AGAIN (NHTSA RECALL #08V157000). AUDI SAID THE FILLER NECK WAS DRY, BUT THERE IS A LEAK SOMEWHERE ON TOP OF FUEL TANK ON THE SAME SIDE AS THE FILLER NECK. THEY SAID THEY COULD NOT SEE WHERE THE LEAK WAS COMING FROM WITHOUT DROPPING THE FUEL TANK FROM THE CAR. AUDI QUOTED THE REPAIR FOR COMPLETELY REPLACING THE FUEL TANK AT ~$3400. A FUEL TANK SHOULD NEVER LEAK, AND THIS IS AN EXTREME SAFETY CONCERN, NOT ONLY FOR THE DRIVERS AND PASSENGERS OF THE CAR, BUT ALL OTHERS ON THE ROAD. THIS IS ALSO A FAILURE OF AN EMISSIONS COMPONENT THAT AUDI NEEDS TO BE RESPONSIBLE FOR SINCE THERE IS RAW FUEL LEAKING ALL OVER THE ROAD.
FUEL VAPORS AND LEAKING FUEL APPEARS WHEN THE FUEL TANK IS FILLED BEYOND 3/4 TANK. THIS IS UNSAFE FOR THE CAR TO BE PARKED INSIDE OF THE GARAGE. THE FUMES MAKE PASSENGERS FEEL ILL. AUDI SERVICE DEPARTMENTS WANT TO CHARGE OVER $2500 TO REPAIR. A RECALL FOR THE ROLLOVER VALVE HAS BEEN PERFORMED; HOWEVER THE AUDI SERVICE TECHS SAY THE LEAKAGE IS COMING FROM SMALL CRACKS IN THE DEFECTIVE TANK. UNABLE TO HAVE THE REPAIR DONE BECAUSE OF COSTS I HAVE DRIVEN THE CAR WITH LESS THAN1/2 TANK OF FUEL FOR SEVERAL YEARS . THE STATE OF UTAH WILL NO LONGER PASS MY VEHICLE INSPECTION DUE TO THE EMISSIONS ISSUE. MY FEAR IS THE LEAKING FUEL COULD BE IGNITED BY ANY NUMBER OF SOURCES INCLUDING EXHAUST/HEAT FROM THE VEHICLE. PASSENGERS SHOULD NEVER HAVE TO BE SUBJECT TO VAPORS INSIDE OF A VEHICLE. I HAVE BEEN TO 3 DIFFERENT UTAH AUDI DEALERSHIPS AND 1 INDEPENDENT AUDI REPAIR GARAGE. I HAVE ALSO CONTACTED AUDI CUSTOMER RELATIONS @ 1-800-253-2834. ALL OF THE AUDI REPRESENTATIVES AND TECHNICIANS HAVE PLAYED DUMB REGARDING THIS ISSUE; YET THE ISSUE CAN BE FOUND IN A NUMBER OF FORUMS WHERE OTHERS HAVE DEALT WITH THE SAME ISSUE. AUDI REFUSES TO TAKE RESPONSIBILITY OR EVEN SHOW REAL CONCERN FOR THIS SAFETY AND ENVIRONMENTAL ISSUE. *TR
I RECENTLY BOUGHT MY AUDI AND THROUGHOUT THE SUMMER IT DROVE JUST FINE, BUT ONCE WINTER CAME AROUND AND THE TEMPERATURES DROPPED, I NOTICED THE SMELL OF GAS IN MY CAR AS SOON AS IT WAS STARTED. I OPENED THE HOOD AND THERE WAS GAS SPRAYING FROM WHAT LOOKED LIKE ALL SIX FUEL INJECTORS. SO I TOOK THE CAR TO A MECHANIC, WHERE THEY REPLACED NUMEROUS THINGS (FUEL PRESSURE REGULATOR, O RINGS, VALVE SYSTEM, AND ALL 6 FUEL INJECTORS) ALL TO NO AVAIL. NOBODY CAN TELL ME WHAT IS WRONG, NOBODY KNOWS. I CALLED AUDI AND THEY TOLD ME I COULD TAKE IT TO A DEALERSHIP BUT THAT THEY COULDN'T PROMISE THEY CAN FIX THE CAR. I CAN'T DRIVE THE CAR, IT IS A SAFETY HAZARD. I HAVE LOOKED ON MANY FORUMS AND THERE HAVE BEEN A FEW OTHER PEOPLE WITH THE SAME PROBLEM BUT NOBODY CAN FIGURE OUT WHAT IS WRONG. IS THERE A RECALL, OR ANY INFORMATION YOU CAN GIVE AS TO HOW TO FIX THIS PROBLEM?? *TR
TYPICAL AUDI FUEL LEAK PROBLEM. THEY SAY IT IS A ROLL OVER VALVE. THEY FIXED IT. IT STILL LEAKS AND NOW IT IS MY PROBLEM AT $2800. *TR
THIS CAR HAS BEEN GREAT TO ME. ASIDE FROM A FUEL PUMP GOING, JUST RECENTLY I WAS DRIVING ON THE FREEWAY AND THE CAR DIED. THE EPC LIGHT ON THE DASH POPPED UP AND LUCKILY I WAS ABLE TO COAST TO THE SIDE OF THE ROAD. I ATTEMPTED TO START THE CAR SEVERAL TIMES BEFORE CALLING AAA (15-20 MIN) WHILE ON THE PHONE WITH AAA I ATTEMPTED TO START THE CAR AGAIN AND IT FIRED RIGHT UP. THINKING IT WAS JUST A ONE TIME ISSUE I GOT BACK ON THE FREEWAY WHERE 10 MILE OR SO LATER SAME THE SAME THING HAPPENED. ANOTHER 20 MIN OF WAITING BEFORE IT CRANKED AGAIN AT THIS POINT I WAS IN A B AD AREA WITH MY FAMILY AND EVERYONE WAS GETTING NERVOUS. AFTER IT STARTED THE EPC LIGHT STAYED ON THIS TIME AND I EXPERIENCED LOSS OF POWER AND THE CAR COUGHED AND STUMBLED TERRIBLY WHEN I NEEDED IT MOST. I MANAGED TO MAKE IT HOME AND LET THE CAR SIT FOR A DAY. HOPED IN AND IT CRANKED RIGHT UP. NO PROBLEMS 15 MILES LATER IT HAPPENED AGAIN. AFTER TALKING WITH OTHER VALUED AUDI OWNERS AND LOOKING OVER THE AUDI OWNER FORUMS. I HAVE FOUND THIS TO BE A QUITE COMMON PROBLEM WITH THE AUDI ACROSS THE RANGE OF THERE A SERIES FROM 1997-2011. PLEASE HELP! *TR
TL* THE CONTACT OWNS A 2002 AUDI A6. THE CONTACT STATED THE CHECK ENGINE LIGHT REMAINED ILLUMINATED. THE VEHICLE WAS TAKEN TO THE LOCAL MECHANIC WHO PERFORMED A DIAGNOSTIC, WHICH LOCATED THE FAILURE AT THE FUEL TANK. THE FUEL TANK WAS LEAKING FUEL. THE MANUFACTURER WAS MADE AWARE OF THE FAILURE, AND ADVISED THAT THE VEHICLE WAS NOT INCLUDED IN NHTSA CAMPAIGN ID NUMBER 08V157000 (FUEL SYSTEM, GASOLINE:STORAGE:TANK ASSEMBLY). THE VEHICLE WAS NOT REPAIRED. THE FAILURE AND THE CURRENT MILEAGE WAS 116,000.
MY CHECK ENGINE LIGHT IS MARKING MISFIRE BUT I HAVE GOTTEN A COMPLETE TUNE-UP, CHANGED ALL 6 COILS ON THE ENGINE CHANGED ALL THE SPARK PLUGS, I'VE DONE EVERYTHING POSSIBLE AND CHANGED EVERYTHING I CAN THAT HAS TO DO WITH THE ENGINE ALL BRAND NEW AND NOTHING HAS WORKED AND ITS STILL SAYING MISFIRE...I'VE GOOGLED THIS PROBLEM FOR AUDI'S AND THERE WERE SO MANY PEOPLE COMPLAINING ABOUT THE SAME THING... ALSO, I AM HAVING A PROBLEM WITH THE ELECTRICAL SYSTEM AS WELL ONE DAY MY WINDOWS WORK THE NEXT IT DOESN'T SOMETIMES MY LIGHTS WILL WORK AND SOMETIMES IT DOESN'T, SOMETIMES MY RADIO WILL WORK SOME TIMES IT DOESN'T, THE INFORMATION ON MY DASH SOMETIMES DOESN'T LIGHT UP AND I CAN'T SEE ANYTHING AT NIGHT TIME, I HAVE CONSTANTLY BEEN TO THE MECHANICS TRYING TO FIGURE OUT WHAT'S GOING ON BUT WE CAN'T FIND THE PROBLEM, I'VE SPENT SO MUCH MONEY ON THIS CAR TRYING TO FIX THE PROBLEMS BUT ITS REALLY MAKING IT HARD FOR ME TO KEEP SPENDING MONEY ON MY CAR AND NOT BEING ABLE TO FIGURE OUT WHAT'S WRONG WITH IT. THIS IS VERY DANGEROUS BECAUSE IF I'M DRIVING AT NIGHT TIME AND MY LIGHTS END UP NOT WORKING I CAN CAUSE A VERY BIG ACCIDENT I AM VERY VERY CONCERNED ABOUT THESE DEFECTS, MY SAFETY AND OTHERS SAFETY AND WOULD REALLY APPRECIATE IF YOU CAN PLEASE INVESTIGATE THIS PROBLEM BECAUSE ITS HAPPENED TO SO MANY PEOPLE. I ALSO THINK SOMETHING IS WRONG WITH THE FUEL SYSTEM I'LL PUT $60 IN GAS AND TWO DAYS LATER IT'LL ALMOST MARK EMPTY I REALLY DON'T UNDERSTAND HOW THAT IS POSSIBLE BUT IF THERE'S AN ANSWER I WOULD REALLY WANT TO KNOW. THANK YOU SO MUCH AND I REALLY APPRECIATE YOUR TIME. *TR
NHTSA CAMPAIGN NUMBER: 08V157000 VOLKSWAGEN IS RECALLING 68,240 MY 2001-2004 AUDI A6 QUATTRO VEHICLES EQUIPPED WITH 2.7L, 2.8L, OR 3.0L ENGINES AND MY 2001-2005 ALLROAD QUATTRO VEHICLES EQUIPPED WITH 2.7L OR 4.2L ENGINES. THE AGING OF THE PLASTIC MATERIAL IN THE FUEL TANK ROLLOVER VALVE COMBINED WITH BENDING STRESS FROM THE ALUMINUM VENTILATION LINE TO THE ROLLOVER VALVE NIPPLE MAY LEAD TO CRACKING OF THE NIPPLE. IF THIS HAPPENS, A FUEL LEAK MAY RESULT. THIS IS THE 3RD TIME I'VE MADE A COMPLAINT. I HAVE A 2002 AUDI A6 WITH THIS PROBLEM AND YET NO ONE WILL LISTEN TO ME. THE REASON IS THAT MY ENGINE IS NOT INCLUDED IN THE RECALL. IT IS THE 4.2 V8 IN THE SEDAN. AUDI COVERED THAT ENGINE ON THE ALLROAD VERSION AND ALL OTHER ENGINES ON THE SEDAN, SO MY ENGINE WAS THE ONLY VERSION NO COVERED. I PERSONALLY SPENT $1200 ATTEMPTING TO FIX THE PROBLEM, BUT I'M TOLD THE LEAK HAS RETURNED AND THE NOTICEABLE SMELL OF GAS IS A TELL-TALE SIGN. THE MECHANIC STATED AND I AGREE, THAT THE ENGINE DISPLACEMENT HAS NOTHING TO DO WITH THE LEAK. ALL THE TANKS ARE THE SAME AND THE 4.2L SHOULDN'T BE OMITTED FROM THIS RECALL. THE SMELL AND POTENTIAL DANGER IS MOST EVIDENT WHEN I FILL THE TANK BEYOND 3/4 FULL. EVERY TIME I START MY CAR, I WONDER IF THIS WILL BE THE EXPLOSION DAY. PLEASE DON'T WAIT UNTIL MY CAR EXPLODES TO AGREE WITH ME. [XXX] INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6). *TR
TL* THE CONTACT OWNS A 2002 AUDI A6. THE CONTACT STATED THAT THE VEHICLE WOULD HESITATE WHEN THE ACCELERATOR WAS DEPRESSED. THE VEHICLE WOULD DRIVE EXTREMELY SLUGGISH UNTIL THE VEHICLE WOULD REACH A SPEED OF 20 MPH. THE VEHICLE WAS INSPECTED BY A MECHANIC THAT ADVISED THE CONTACT THAT THE FUEL PUMP WAS FAILING. THE VEHICLE WAS NEITHER INSPECTED NOR REPAIRED FOR THE FAILURE. THE FAILURE MILEAGE WAS 88,000 AND THE CURRENT MILEAGE WAS 92,538.
THERE IS A KNOWN ISSUE WITH THE AGING OF PLASTIC MATERIAL ON AUDI A6 MODELS YRS 2001-2005.THE AGING OF THE PLASTIC MATERIAL IN THE FUEL TANK ROLLOVER VALVE COMBINED WITH BENDING STRESS FROM THE ALUMINUM VENTILATION LINE TO THE ROLLOVER VALVE NIPPLE MAY LEAD TO CRACKING OF THE NIPPLE.IF THIS HAPPENS, A FUEL LEAK MAY RESULT. THIS EXACT ISSUE HAS BEEN DIAGNOSED BY AN AUDI MECHANIC ON MY 2002 AUDI A6 4.2. IT IS CONSTANTLY LEAKING A FUEL AND IF AN IGNITION SOURCE GETS NEAR IT THERE IS GOING TO BE A VEHICLE FIRE. THE RECALL NUMBER FOR THIS ISSUE IS 08V157000: FUEL TANK ROLLOVER VALVE MODIFICATION. ALTHOUGH THIS IS A KNOWN ISSUE IT ONLY COVERS AUDI A6 MODES WITH 2.7, 2.8, AND 3.0 ENGINES.MY AUDI A6 HAS A 4.2 ENGINE, SO IT IS NOT COVERED BY THE RECALL, BUT THE RECALL DOES COVER THE AUDI ALLROAD EQUIPPED WITH 2.7 AND 4.2 ENGINES. I'VE CALLED AUDI AND THEY REFUSE TO COVER MY VEHICLE UNDER THIS RECALL BECAUSE THEY HAVE NOT HAD ENOUGH REPORTS OF IT OCCURRING WITH MY SPECIFIC ENGINE MODEL. I HAVE A DAUGHTER AND THIS POSES A VERY DANGEROUS THREAT, ITS EXPENSIVE TO REPAIR ON MY OWN AND IS A KNOWN ISSUE REPORTED ON THE SAME VEHICLE I OWN BUT BECAUSE I HAVE THE 4.2 MODEL THEY REFUSE TO COVER IT UNDER THEIR RECALL. *TR
I HAVE A 2002 AUDI A6 WITH A 3.0 V-6 ENGINE. WHEN THE GAS TANK IS FILLED UP MORE THAN 3/4 FULL THE GAS TANK ON THE DRIVERS SIDE LEAKS ALL OVER THE PLACE. ON THE INTERNET THERE ARE MANY COMPLAINTS EXPLAINING THE SAME EXACT PROBLEM. AUDI HAS A RECALL PROGRAM FOR 2001 TO 2004 AUDI A6 3.0 LITRE MODELS, BUT TELL ME MY CAR IS NOT ONE THAT GOT RECALLED BECAUSE OF MY VEHICLE CODE NUMBER. I EXPLAINED THAT MY PROBLEM IS EXACTLY LIKE THEY EXPLAIN ON THEIR WEBSITE AND IT MATCHES THE OTHER COMPLAINTS ON THE WEB ALSO. THE DEALER SAID THEY WERE SURE THE GAS TANK HAS DISSOLVED BECAUSE OF THE GASOLINE AND SAID THEY WANT $2,200 FOR A NEW GAS TANK AND A $100 PER HOUR TO FIX THEIR ENGINEERING PROBLEM. THIS IS A MAJOR SAFETY AND POLLUTION PROBLEM THAT IS WIDE SPREAD THROUGHOUT OUR COUNTRY AND NEEDS TO BE ADDRESSED ASAP. HELP ! *TR
THIS COMPLAINT IS RELATED TO AN AUDI RECALL #PE08008 ISSUED IN MAY, 2008 AND RELATES TO THE FAILURE OF THE A PLASTIC NIPPLE ON THE GAS TANK THAT FAILS DUE TO STRESS. ACCORDING TO AUDI, MY VEHICLE DID NOT FALL WITHIN THE PARAMETERS OF THE RECALL PER MY VIN . ACCORDING TO YOUR NOTICE IT COVERS MY 2002 AUDI, BUT ONLY FOR THE 2.8, 2.7 AND 3.0 ENGINE ON THE QUATTRO SEDAN AND THE 2.7 AND 4.2 ON THE ALLROAD. MY AUDI IS A QUATTRO 4.2 SEDAN. 2 YEARS AGO, I NOTICED THE SMELL OF FUEL AROUND THE REAR OF THE CAR AND TOOK IT TO MY REPAIR FACILITY WHERE THEY DIAGNOSED THE EXACT SAME PROBLEM AS DESCRIBED IN YOUR RECALL. MY REPAIR INVOLVED DROPPING THE BACK-END TO ACCESS THE TANK AND ACTUALLY WELDING THE PLASTIC NIPPLE. I ONLY FOUND OUT ABOUT THE RECALL BY CHANCE AND CALLED AUDI, BUT THEY TELL ME MY CAR IS NOT PART OF THE RECALL. I DON'T UNDERSTAND HOW IT CAN'T BE. *TR
DT*: THE CONTACT STATED A PUDDLE OF GAS WAS OBSERVED UNDER THE VEHICLE. IT WAS TAKEN TO THE DEALER WHERE THEY DISCOVERED A GAS LEAK. A SEALANT WAS PLACED ON THE GAS TANK HOWEVER THE PROBLEM PERSISTED. UPDATED 09/12/06.*JB
CAR ENGINE HAD STOPPED IN THE MIDDLE OF A BUSY HIGHWAY. THE FUEL GAUGE SHOWED THAT THERE WAS HALF A TANK OF GAS LEFT. IN REALITY THERE WAS NO FUEL IN THE CAR. CAR HAD TO BE TOWED AT OWNERS EXPENSE. FUEL SENDER UNIT HAD TO BE REPLACED AT OVER $500. THERE WAS A RECALL FOR THE SAME REASON FOR THE SAME PROBLEM FOR 2001 MODEL, BUT NOT 2002 WHICH HAS THE SAME PROBLEM. EXTREME DANGER TO A SAFETY OF THE DRIVER. THE CAR CAN RUN OUT OF FUEL WITH A FUEL GAUGE SHOWING THAT THERE IS A HALF A TANK OF GAS LEFT. *NM
