NHTSA Complaint #10264373 — 2005 VOLKSWAGEN PASSAT

THERE IS A PROBLEM WITH THE BHW ENGINE IN MY 2005 PASSAT TDI THE BALANCE SHAFTS IN THIS ENGINE ARE DRIVEN BY A CHAIN OFF THE MOTOR, WHICH ALSO DRIVES THE OIL PUMP. THIS UNFORTUNATE DESIGN SUBJECTS THE CHAIN TO STRESSES IT CANNOT WITHSTAND. ON VARIOUS TDI FORUMS, ESPECIALLY TDICLUB.COM, THERE ARE A SIGNIFICANT NUMBER OF CHAIN FAILURES BEING REPORTED. OF COURSE, WHEN THE CHAIN DRIVING THE OIL PUMP FAILS, THE ENGINE IS STARVED OF ESSENTIAL LUBRICATION. IF THE FAILURE OF THE CHAIN CAUSES ENGINE TO STOP RUNNING IN THE MIDDLE OF TRAFFIC, MERGING ONTO A HIGHWAY, OR PASSING ON THE HIGHWAY, THIS CONDITION COULD EASILY CAUSE DANGER TO ALL CITIZENS NEARBY, POSSIBLY LEADING TO DEATH. RECENTLY, VOLKSWAGEN IN EUROPE RECOGNIZED THE PROBLEM AND DESIGNED A REPAIR, WHICH CHANGES THE CHAIN DRIVEN OIL PUMP TO A GEAR DRIVEN OIL PUMP. THIS APPEARS TO BE A PERMANENT FIX TO THE ORIGINAL DESIGN DEFECT. THE REPAIR IS QUITE EXPENSIVE. WHEN THE CHAIN FAILS, THE PARTS TO REPAIR COST APPROXIMATELY $1800 PLUS APPROXIMATELY ANOTHER $1500 IN LABOR BILLS TO HAVE THE PARTS INSTALLED. IF THE ENGINE IS DESTROYED, IT WILL COST THE OWNER APPROXIMATELY $8000 TO REPLACE THE ENGINE. THIS IS UNACCEPTABLE. I BELIEVE IT IS NOW OBVIOUS THAT ALL THE BHW ENGINES WILL FAIL UNLESS THE GEAR DRIVEN OIL PUMP MODIFICATION IS UNDERTAKEN. IT IS UNFAIR TO EXPECT OWNERS OF THESE VEHICLES TO PAY FOR THE REPAIRS. THE PROBLEM ORIGINATED WITH A FLAWED DESIGN. THIS IS NOT A SMALL PROBLEM, AS THIS DESIGN FLAW WILL LEAD TO TOTAL ENGINE FAILURE. MY VEHICLE IS CURRENTLY EXPERIENCING SEVERE NOISE OSCILLATIONS THAT IS ATTRIBUTED TO IMMINENT FAILURE OF THE AFOREMENTIONED CHAIN ASSEMBLY. THUS, I MUST PAY TO REPAIR THIS DESIGN FLAW BEFORE IT CAN CAUSE AN ACCIDENT. SO FAR, VOLKSWAGEN OF AMERICA HAS NOT PROVIDED ADEQUATE SUPPORT FOR RESOLVING THIS DESIGN PROBLEM. *TR
