FUEL/PROPULSION SYSTEM

I HAVE ENCOUNTERED THE PROBLEM OF AIR BUBBLE FORMATION IN MY FUEL SYSTEM (CODE 16903) WHEN READING CODES IN MY CAR. I THOUGHT IT WAS JUST A FUEL PUMP ISSUE SO I REPLACED IT. I THEN REALIZED IT WASN'T JUST A PUMP ISSUE AS THE CAR KEPT READING THOSE CODES AND KEPT STOPPING. I TALKED TO A LOCAL AUDI DEALERSHIP AND SAID I WOULD HAVE TO GET THE FUEL PUMP VAPOR EXTENSION. WHEN ASKED THEY SAID THAT IT'S ONLY A TSB NOT A RECALL DUE TO IT NOT BEING A SAFETY ISSUE. NOW YOU TELL ME, MY CAR WENT INTO LIMP MODE AND STOPPED ONCE IN THE MIDDLE OF THE HIGHWAY, AND 3 TIMES IN THE MIDDLE OF TRAFFIC 2 WEEKS LATER. I BELIEVE IT'S A SAFETY PROBLEM AS ANYONE COULD'VE RAN INTO ME AND CAUSED BIGGER PROBLEMS. I DON'T THINK I SHOULD PAY 800 DOLLARS FOR MY SAFETY. THAT PIECE SHOULD'VE BEEN INCLUDED IN THE FUEL PUMP ASSEMBLY FROM THE BEGINNING. FROM MY PERSPECTIVE AND THE EVENTS THAT UNFOLDED, THIS IS A SAFETY PROBLEM AND MY CAR NEEDS TO BE FIXED ACCORDINGLY.

FUEL/PROPULSION SYSTEM

WHILE TRAVELING AT 75MPH, UPHILL, IN 100F WEATHER THE FUEL LOW PRESSURE FUEL SYSTEM DEVELOPED A VAPOR BUBBLE THAT STALLED THE LOW PRESSURE FUEL PUMP AND STARVED THE MOTOR FOR FUEL. THE CAR STALLED ON THE FREEWAY AND WOULD INTERMITTENTLY RESTART UNTIL THE LOW PRESSURE FUEL PUMP FAILED. THE REPAIR REQUIRED ADDITIONAL VALVES AND HOSES HE ADDED TO THE LOW PRESSURE FUEL SYSTEM TO COMPENSATE FOR THE POOR VAPOR MANAGEMENT DESIGN. THE CAR HAD TO BE TOWED TO A DEALERSHIP WHERE THE APPROPRIATE FIX AND TSB WAS EXECUTED. TOTAL COST WAS ~$2200, $715 OF THAT TOTAL COST WERE THE NEW VALVES AND HOSES THAT SHOULD HAVE BEEN PART OF THE INITIAL DESIGN.

FUEL/PROPULSION SYSTEM

AFTER 2 ENGINE OIL LEAKS, IN 2.5 YEARS, I SMELLED GAS FUMES IN THE CABIN NUMEROUS TIMES, SCHEDULED AN APPT FOR A CHECK WITH THE WEST ISLIP NY AUDI DEALERSHIP. PICKED UP CAR FROM DEALERSHIP, WITH WORK ORDER AND SERVICE REP. SIMPLY STATING "NO PROBLEM FOUND" UNDER EACH OF MY 5 CONCERNS, WHICH TOLD ME THAT THEY DID NOT EVEN LOOK AT THE ISSUES. WITH EVERY WORK ORDER, WHICH ARE NUMEROUS ON THIS CAR, IT IS STATED WHAT WAS DONE, BUT NOT THIS "SERVICE". TWO DAYS AFTER PICKING UP MY VEHICLE, AUDI REPORTED A RECALL DUE TO GAS LEAKS IN THEIR VEHICLES. MY VEHICLE IS STILL UNDER LEASE AND WARRANTY, YET THIS DEALERSHIP TOOK IT UPON THEMSELVES TO IGNORE MY CONCERNS, WHICH COULD POTENTIALLY BE FATAL.? ABSOLUTELY NO INTEGRITY, AND LACKING ANY SENSE OF MORALS.

TL* THE CONTACT OWNS A 2012 AUDI S4. THE CONTACT STATED THAT THE VEHICLE EXHIBITED A FUEL LEAK. THE VEHICLE WAS TOWED TO THE DEALER HOWEVER, THE TECHNICIAN WAS UNABLE TO DIAGNOSE THE FAILURE. THE MANUFACTURER WAS MADE AWARE OF THE FAILURE BUT DID NOT OFFER ANY ASSISTANCE. THE VEHICLE WAS NOT REPAIRED. THE FAILURE MILEAGE WAS 10,500 AND THE CURRENT MILEAGE WAS 14,200.

FUEL SYSTEM, GASOLINE

I OWN TWO OF THE ORIGINAL AUDI S4'S, BOTH 1993 MODELS. MY DAUGHTER WAS DRIVING ONE OF THESE CARS IN 2007 AND THE THROTTLE STUCK OPEN SO THAT THE ENGINE RACED UNCONTROLLABLY. SHE WAS ABLE TO PUT THE CLUTCH IN AND STOP THE CAR AND TURN THE ENGINE OFF. THEN SHE HAD THE CAR TOWED TO THE NEAREST REPAIR SHOP. IT WAS DISCOVERED THAT A PLASTIC PART ON THE TIP OF THE THROTTLE CAM HAD BROKEN OFF AND AS A RESULT THE THROTTLE CABLING MECHANISM STUCK IN THE PARTIALLY "OPEN" POSITION. I HAD THE THROTTLE CAM REPLACED WITH AN ALL STAINLESS STEEL CAM WHICH CANNOT BREAK DOWN AS A RESULT OF HEAT, AS PLASTIC OR A SIMILAR PRODUCT CAN DO. I HAD OEM CAMS REPLACED IN BOTH S4'S. AUDI DEALER WAS NOTIFIED OF THE PROBLEM IN OCTOBER 2007. I HAVE RECOMMENDED TO AUDI THAT ALL 1992-1997 S4 AND S6 MODELS BE RECALLED AND THAT ALL THROTTLE CAMS BE REPLACED WITH AN ALL STAINLESS STEEL CAM (FOR EXAMPLE, ONE FABRICATED BY 034 MOTORSPORT IN FREMONT, CA.) AT LEAST ONE OTHER INSTANCE OF UNINTENDED ACCELERATION, DUE TO FAILURE OF THE OEM THROTTLE CAM, HAS BEEN REPORTED ON THE "WEB" -- IN FACT THAT REPORT LED ME TO 034 MOTORSPORT'S SOLUTION. I KNOW I NEVER RECEIVED, FROM AUDI, A NOTICE OF THIS POTENTIAL PROBLEM. DATE SHOWN BELOW IS APPROXIMATE. I WOULD HAVE TO FIND THE TOWING BILL TO BE PRECISE.

FUEL SYSTEM, GASOLINE

FRONT HEADLIGHTS (BOTH SIDES) FLICKER(BLINK) BUT NOT ALL THE TIME. WHEN THEY FLICKER I TURN THEM OFF AND THEN TURN ON AGAIN, THEN THEY ARE FINE. BUT I AM WORRIED THAT IT MAY GO BAD DURING DRIVING CAUSING SAFETY ISSUES. ITS NOT THE BULB ISSUES AS ON-BOARD DIAGNOSTICS WOULDN'T DETECT THE PROBLEM. IT HAS HAPPENED SEVERAL TIMES OVER LAST COUPLE OF WEEKS. I TRIED FINDING SOLUTION ONLINE AND FOUND THIS FORUM HTTP://FORUMS.AUDIWORLD.COM/SHOWTHREAD.PHP?P=23809262. THIS TELLS ME THIS PROBLEM IS PART OF NOTORIOUS DESIGN BY AUDI OF AMERICA. MY CAR IS OUT OF WARRANTY AND AUDI WOULDN'T TAKE CARE OF IT AS THEY HAVE PROVIDED NO ASSISTANCE TO SORT OUT OTHER MECHANICAL ISSUES WITH MY CAR WHICH HAS ONLY 50000 MILES. THOSE ISSUES INCLUDE FAILING OF FUEL PUMPS, LEAKING OF TRANSMISSION FLUID AND MELTING OF GASKET COVER CAPS (MAIN) LEADING TO INCONVENIENCE AND FINANCIAL STRESS FOR US AND ON A CAR WHICH IS NOT EVEN 12 MONTHS OUT OF WARRANTY. I REQUEST YOU TO DO YOUR RESEARCH AND HOPE THEY DO A RECALL FOR THESE FAULTY HEADLIGHTS.

FUEL SYSTEM, GASOLINE

I RUN A SMALL REPAIR SHOP AND HAVE SEEN A NUMBER OF AUDI VEHICLES FROM 1986 TO 1998 WHICH HAVE STEEL GASOLINE LINES THAT COLLECT ROAD SALT AND RUST IN THE RUBBER SUPPORT GROMMETS ATTACHED TO THE CHASSIS. THE RUST CAUSES A PINHOLE LEAK WHICH THEN BEGINS TO SPRAY GASOLINE ON THE EXHAUST SYSTEM. I HAVE SEEN 5 OR 6 VEHICLES LIKE THIS IN THE PAST 5 YEARS AND SAW ANOTHER ONE LAST WEEK.

FUEL SYSTEM, GASOLINE:FUEL INJECTION SYSTEM

THERE IS A SEVERE SAFETY PROBLEM ASSOCIATED WITH THE AUDI 94S4, OTHER MODEL YEAR S CARS AND OTHER AUDI CARS WITH THE 100 BODY. WHEN THE PLASTIC PART THAT CONNECTS THE THROTTLE BODY TO THE THROTTLE CABLE BREAKS, THE ENGINE GOES UP TO 7000 RPM (OVER RED LINE). IF IN HEAVILY CONGESTED TRAFFIC AS I WAS, THE OWNER RISKS HIS LIFE OR HIS ENGINE. SINCE I DECIDED MY LIFE AND THAT OF MY PASSENGERS WAS MORE IMPORTANT THAN THE ENGINE, I LET THE ENGINE RACE AND USED THE BRAKE TO CONTROL SPEED UNTIL I COULD SAFELY GET OFF THE BELTWAY AND ONTO A SIDE ROAD. ONCE THERE, I SAW THAT MY EXHAUST MANIFOLD HAD GOTTEN CHERRY RED WITH AND COULD HAVE CAUSED A FIRE. THESE CARS NEED IMMEDIATE RECALL AS A SAFETY MEASURE AND THE PART REPLACED WITH METAL. FAILURE WAS WITHOUT WARNING, CAR''S SPEED BEGAN TO INCREASE WITHOUT WARNING AND THROTTLE PRESSURE HAD NO IMPACT WHATSOEVER. LESS SKILLFUL PERSON WOULD HAVE PANICKED AND CAUSED SEVERE PILE-UP IN RUSH HOUR TRAFFIC. MANY OTHER AUDI OWNERS HAVE REPORTED THE PROBLEM ON THE VARIOUS COMPUTER LISTS AND WEB SITES USED BY AUDI OWNERS. CALL OR WRITE FOR DETAILS. AUDI DEALER WAS UNCONCERNED ABOUT PROBLEM AND PART IS NOT LISTED NOR CAN BE PURCHASED SEPARATELY. MUST PURCHASE ENTIRE THROTTLE BODY AT COST OF OVER $800.

FUEL SYSTEM, OTHER:STORAGE:FUEL GAUGE SYSTEM

THE PROBLEM I AM EXPERIENCING IS ANALOGOUS TO A RECALL ALREADY ANNOUNCED FOR THE AUDI A6: NHTSA RECALL NO. 00V-147, VW RECALL NO. UR **LA I HAVE A 2000 AUDI S4 WITH 64,000 MILES. I RECENTLY RECEIVED MY CAR BACK FROM A 64,000 MILE SERVICE. MY GAS GAUGE HAD INDICATED I HAD AT LEAST A QUARTER TANK OF GAS LEFT, AND MY TRIP COMPUTER INDICATED I HAD MORE THAN 60 MILES UNTIL EMPTY. I WAS ON THE HIGHWAY WHEN THE CAR STARTED SPUTTERING. AT FIRST, I DIDN'T KNOW WHAT THE PROBLEM WAS. LUCKILY, I WAS ABLE TO TURN THROUGH 3 LANES OF TRAFFIC WITH NO POWER AND GET INTO THE EMERGENCY LANE. I CHECKED MY CAR, AND THERE WERE NO OBVIOUS SIGNS OF THE PROBLEM. I HAPPENED TO NOTICE THAT MY TRIP COMPUTER MILES COUNTER (WHICH I RESET ON EVERY FILL-UP), WAS READING HIGHER THAN WOULD BE TYPICAL. IT WAS AT THAT POINT THAT I SUSPECTED I HAD RUN OUT OF GAS. I CALLED AAA, REQUESTING A GALLON OF GAS. INDEED, THIS SOLVED THE PROBLEM. I WAS FORTUNATE IN MY SITUATION. I DOUBT OTHERS WHO ALSO EXPERIENCE THIS PROBLEM WOULD BE AS LUCKY. I'VE ALREADY HEARD MANY STORIES ON CAR FORUMS, ETC. OF OWNERS HAVING 'CLOSE CALLS' BECAUSE THEY'VE RUN OUT OF GAS WHEN THEY DON'T EXPECT TO. THIS PROBLEM HAS BEEN LINKED TO THE SENDING UNIT AUDI USES IN THESE MODELS. THERE HAVE BEEN MANY FAILURES, AND IT IS ALL TOO COMMON A PROBLEM THAT NEEDS TO BE ADDRESSED. IT IS ABSOLUTELY IDENTICAL TO THE SENDING UNIT FAILURES ON THE 2000 A6, SO I DON'T UNDERSTAND WHY IT WOULDN'T BE ADDRESSED ON THE 2000 A4/S4 (B5 PLATFORM) OR ANY OTHER MODEL THAT USES THE SAME UNIT.

BUZZING NOISE IN BACK OF CAR TURNED OUT TO BE FAULTY FUEL PUMP. AFTER SEVERAL DAYS IN SHOP THE SERVICE REP TOLD ME THAT THERE WAS ANOTHER PROBLEM -- A "BURNT" OR "CORRODED" WIRE NEAR THE FUEL PUMP AND FUEL TANK THAT COULD BE A "SAFETY ISSUE." THAT WAS 3 DAYS AGO. STILL NO UPDATE FROM THE DEALERSHIP. I AM WONDERING IF OTHERS HAVE HAD PROBLEMS WITH THE FUEL PUMP ON THE AUDI S4. I'M PARTICULARLY WORRIED BECAUSE EXPOSED WIRES NEAR A FUEL TANK SOUNDS LIKE A SERIOUS SAFETY ISSUE.

FUEL SYSTEM, GASOLINE:DELIVERY

I HAD PREVIOUSLY CONTACTED NHSTA REGARDING FUEL LINE LEAKS IN THE ENGINE COMPARTMENT OF THE EALRY S4 AND S6 MODELS. THIS RESULTED IN THE "KY" RECALL CAMPAIGN. MORE RECENTLY, SOME OWNERS HAVE BEEN DISCOVERING LEAKS IN THE FUEL LINES GOING FROM THE REAR OF THE CAR TO THE FRONT. THESE LEAKS OCCUR AT THE POINT WHERE THE FUEL LINE GOES THROUGH RUBBER ISOLATION/MOUNTING BLOCKS. MOISTURE ACCUMULATES AT THESE POINTS AND CORRODES THE FUEL LINE RESULTING IN LEAKS. I DISCOVERED THIS ON MY OWN CAR IN EARLY 2002 AND I KEEP HEARING FROM MORE AND MORE PEOPLE FINDING THE SAME THING. THESE CARS HAVE BEEN EXTREMELY GOOD IN OTHER AREAS BUT THE FUEL SYSTEM PLUMING LEAVES MUCH TO BE DESIRED. DT
