NHTSA Complaint #10273921 — 2007 AUDI A4

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
