NHTSA Complaint #10383187 — 2007 AUDI A4

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
