THE CAR ENGINE STOPPED WORKING WHILE DRIVING ON THE HIGHWAY 280, LANE NEXT TO THE SHOULDER. I FELT THE ENGINE STOPPED AND WAS ABLE TO TURN THE WHEEL TO GET IT OVER TO THE SHOULDER. I CALLED AAA TO TOW IT TO THE AUDI DEALERSHIP IN SAN JOSE, STEVENS CREEK. AUDI DEALERSHIP PREFORMED A DIAGNOSTIC ON MY AUDI, DIAGNOSTIC READS THAT THE FUEL PUMP, SEAL AND FUEL FILTER NEEDS TO BE REPLACED . THE DEALERSHIP SAID THAT THIS IS NOT COVERED UNDER WARRANTY AS THE HISTORY PAPERWORK HAS REPAIRS DONE FOR THE SAME ISSUES. I CALLED THE AUDI MANUFACTURER AND A REP NAMED SHY IS WORKING ON MY REQUEST TO HELP RESOLVE THIS ISSUE AS SHE SEEN HAT THERE IS A WARRANTY FOR THIS ISSUE. BUT, I CALLED 2 PRIOR TIMES TO THE AUDI MANUFACTURER AND GOT THE RUN AROUND. *TR

HIGHLY COMMON FAILURE WITH THE HIGH PRESSURE FUEL PUMP(HPFP)AND RELATED PARTS IN 2005.5-2008 AUDI A4 2.0T FSI ENGINES. 'CAM FOLLOWER' THAT IS A BUFFER BETWEEN INTAKE CAMSHAFT LOBE AND HPFP LOCATED ON THE INTAKE MANIFOLD. WHEN PART FAILS, IT WEARS HOLE IN BUFFER "CAM FOLLOWER" WHICH RESULTS IN EXCESSIVE WEAR TO INTAKE CAMSHAFT AND FUEL PUMP PISTON AND SPRING. NO UNUSUAL CIRCUMSTANCES LED UP TO THE FAILURE. NORMAL HIGHWAY/CITY MIX DRIVING. OCCASIONAL FUEL CUTOFF IS THE ONLY HINT THAT THE PART IS FAILING, AND ONLY HAPPENS WHEN DRIVING IS MORE SPIRITED. -- HTTP://WWW.AUDIZINE.COM/FORUM/SHOWTHREAD.PHP/295208-FAQ-OFFICIAL-THREAD-FOR-YOUR-CAM-FOLLOWER%28S%29.?HIGHLIGHT=HPFP+UPGRADE LINK IS TO A AUDI OWNER FORUM; THIS PARTICULAR THREAD HIGHLIGHTS THE SERIOUS NATURE OF THE FAILURE. FAILURE IN MY CASE LED TO FREQUENT FUEL CUTOFF, PARTICULARLY WHEN TRYING TO PASS(WHEN CAR SHIFTS DOWN TO PASS AND THUS RESULTING IN THE NEED FOR MORE FUEL AT HIGHER REVS) FAILURE IN MY CASE CAUSED ME TO HAVE TO REPLACE THE INTAKE CAMSHAFT, CAM FOLLOWER, FUEL PUMP AND OTHER MAINTENANCE PARTS AT EXTENSIVE COST (SEVERAL THOUSANDS OF DOLLARS) ACCORDING TO LINK PROVIDED, FAILURE CAN AFFECT VEHICLE AT ANY TIME, VERY FEW MILES UP TO 70,XXX+ MILES, MODIFIED OR STOCK. NO ONE IS COMPLETELY SAFE FROM THIS ISSUE. AUDI DEALERSHIPS ACROSS THE COUNTRY HAVE BEEN MADE AWARE THAT THIS IS A COMMON ISSUE, BUT LITTLE HELP HAS BEEN GIVEN TO REMEDY THE SITUATION. CAMSHAFT REVISIONS HAVE BEEN DEVELOPED IN ORDER TO ADDRESS THE PROBLEM, BUT ARE ONLY INSTALLED WHEN PART HAS FAILED. NEW REVISION CAMSHAFT IS PRONE TO THE ISSUE AS WELL, IT DOES NOT SOLVE THE PROBLEM. JUST A POOR BAND-AID. THIS ISSUE GOES BEYOND A MAINTENANCE ISSUE, AND BECOMES A SAFETY ISSUE WHEN A VEHICLE IS UNABLE TO UTILIZE ITS PASSING ABILITIES TO AVOID OTHER DRIVERS. FUEL CUTOFFS LEAD TO LOSS OF POWER IN MOTOR THUS MAKING IT A SAFETY ISSUE. *LN

I HAVE AN AUDI A4 2007. FRIDAY, MARCH 5 I WAS DRIVING TO WORK AND THE CAR STARTING REVVING BY ITSELF, BUT SLOWING DOWN AT THE SAME TIME. I WAS FORCED TO PUT IT IN NEUTRAL AND COAST TO THE SIDE OF THE ROAD. TOOK IT TO THE DEALER, THEY SAID IT WAS THE FUEL PUMP, REPLACED IT. SATURDAY, I WAS THE LAST CAR ON AN EXIT RAMP PREPARING FOR LIGHT TO CHANGE, BUT WHEN I PUSHED THE GAS, THE ENGINE REVVED TO 5, BUT WOULD NOT MOVE. CAR WAS IN DRIVE POSITION. WHILE THIS WAS HAPPENING, A FORD F-150 WAS HEADING TOWARDS THE REAR OF MY CAR, BUT SWERVED IN TIME I ASSUME AFTER SEEING MY HAZARDS ON, WHICH I DID IMMEDIATELY. THE TRUCK BARELY MISSED CLIPPING ME. FINALLY, I TURNED THE CAR OFF AND BACK ON, AND IT GOT UP TO ABOUT 20 MILES PER HOUR, ENOUGH FOR ME TO GET OFF THE EXIT RAMP. THIS CAR BURNS OIL THROUGH EVERY 1200-1500 MILES. AUDI IS AWARE OF THIS PROBLEM, IN ADDITION TO THE IGNITION COIL PROBLEMS WITH THIS VEHICLE. I HAD 4 COILS REPLACED, BUT ONLY AFTER I GOT THE LETTER OF THE RECALL FROM AUDI. I WAS TOLD THE WHOLE TIME THE JERKING OF THE MISFIRED COILS WAS 'NORMAL'. I AM NOT THE ONLY ONE WHO HAS HAD THE SAME ISSUES. THIS YEAR OF CAR IS UNSAFE, AND SHOULD BE RECALLED TO FIX THE OIL CONSUMPTION ISSUES BEFORE THE DAMAGE OCCURS TO THE ENGINES. *TR

UPON READING OF A HIGH NUMBER OF FAILURES AND EXCESSIVE WEAR ON THOSE YET TO FAIL WITH UNDER 50K MILES ON THEM, I CHECK THE "CAM FOLLOWER" INSIDE THE HIGH PRESSURE FUEL PUMP OF MY 2007 AUDI A4. SURE ENOUGH, IT EXHIBITS SIGNS OF EXCESSIVE WEAR AND WELL ON IT'S WAY TO FAILURE - AND EXPENSIVE REPAIRS AND REPLACEMENT PARTS. THE DEALERSHIP REFUSES TO REPLACE THE CAM FOLLOWER, A $50 DOLLAR PART UNTIL IT FAILS AND CAUSES DAMAGE TO THE ENGINE'S CAM AND HIGH PRESSURE FUEL PUMP. AUDI HAS ISSUED A TECHNICAL SERVICE BULLETIN ON THE PROBLEM. I ONLY HAVE 6 MONTHS OF WARRANTY TO GO. UPON FAILURE, REPAIRS ARE APPROX $1,100.00. *TR

FUEL CUT-OFF/SURGING WHEN ACCELERATING. ENGINE IS NOT THROWING ANY ENGINE CODES; HOWEVER, A LOSS OF POWER IS PRESENT WHEN ACCELERATING. THIS OCCURS EVERY TIME I TRY TO ACCELERATE. THIS IS A KNOWN ISSUE WITH THE CAM FOLLOWER AND HIGH PRESSURE FUEL PUMP ON ALL 2.0T FSI MOTORS FROM AUDI AND VW. MY CAM FOLLOWER HAS A HOLE IN IT (HAVE THE PART) AND THE HPFP IS WORN DOWN BECAUSE IT HAS MADE CONTACT WITH THE CAM LOBE, WHICH HAS BEEN SCARRED. REPLACEMENT REQUIRES A NEW CAM, HPFP AND CAM FOLLOWER. THE DESIGN HOWEVER WILL REQUIRE CONSTANT INSPECTION OF THE CAM FOLLOWER TO AVOID MAJOR ENGINE FAILURE. ALL 2.0 T FSI ENGINES WILL EXPERIENCE THIS PROBLEM. AUDI HAS A TSB #2013147/4 DATED JUNE 18, 2007 THAT WARNS OF THIS PROBLEM UPON CEL LIGHT BEING SHOWN. MY CAR NEVER SHOWED THE CEL LIGHT; HOWEVER, HAD THE OTHER SYMPTOMS DESCRIBED AND UPON FURTHER INSPECTION HAD A HOLE IN THE CAM FOLLOWER, WITH SEVERE DAMAGE TO THE CAM AND HPFP. *TR
