2010 Volkswagen Jetta Fuel System Diesel Power Train Engine Problems

DRIVING ON HIGHWAY ON 12/15/13 AND AS I ACCELERATED, I LOST POWER AND "CHECK ENGINE LIGHT" CAME ON. CAR FELL TO 50MPH AND I EXITED HIGHWAY IMMEDIATELY, STOPPED THE CAR, RE-STARTED AND THE CAR AND LIGHT WAS STILL ON. SHOWED ERROR CODE G450 AND THE "EXHAUST PRESSURE SENSOR 1" WAS REPLACED BY DEALER IN JANUARY 2014. GLOW PLUG LIGHT ALSO CAME ON INTERMITTENTLY AT THAT TIME. TWO MONTHS LATER (FEBRUARY, 2014), "GLOW PLUG LIGHT" CAME ON AGAIN INTERMITTENTLY. TURNED OFF CAR AND STARTED IT AGAIN AND LIGHT WENT OUT. DEALER SAYS P0237 CODE MEANS INTERMITTENT FAILURE OF "BOOST PRESSURE SENSOR" AND "SENSOR HARNESS". VW ADVISES THE CAR IS NOT DRIVABLE DUE TO UNPREDICTABLE PERFORMANCE OF TURBOCHARGER ON ENGINE PERFORMANCE DUE TO FAILURE OF THIS SENSOR. THE LOSS OF POWER HAS BEEN DOCUMENTED WIDELY FOR THIS ENGINE (PUMP, CARBONIZED INTAKE, OTHER?), BUT VW HAS ACCEPTED NO RESPONSIBILITY FOR THE PROBLEM. CAR IS 4 YEARS OLD WITH 48,900 MILES. REPAIRS ARE APPROACHING $1000 AT THIS TIME. *TR

CAME TO A STOP AT A LIGHT AND THE CAR WAS FINE AT FIRST. THEN, ALL OF A SUDDEN THE RPMS STARTED BOUNCING AROUND AND THE CAR TURNED OFF. IT WOULDN'T TURN ON FOR ABOUT A MINUTE AND I WAS ABLE TO DRIVE OFF. THE INCIDENT HAS HAPPENED AGAIN ON AT LEAST 3 OCCASIONS. NAME-BRAND DIESEL HAS ALWAYS BEEN USED, FULL MAINTENANCE HAS BEEN FOLLOWED INCLUDING FUEL FILTER REPLACEMENT AND DSG TRANSMISSION SERVICE. *TR

2010 VW JETTA 2.0 TDI CUP EDITION: ENTERING TRAFFIC IN FIRST GEAR, AT ABOUT 4000-4200 RPM, CAR HAD A COMPLETE LOSS OF POWER. ENGINE DID NOT DIE. I PUSHED IN CLUTCH AND POWER RETURNED. THIS HAS OCCURRED MONTHLY WITH NO CONSISTENCY SINCE I PURCHASED THE CAR IN JULY 2010. OCCURS WITH A WARM ENGINE. COLD ENGINE. VARIOUS LEVELS OF FUEL, AND VARIOUS CLIMATE CONDITIONS. IT HAS BEEN TAKEN TO O'BRIEN VOLKSWAGEN, A CERTIFIED REPAIR FACILITY, EVERY 3-6 MONTHS TO HAVE THE ISSUE RESOLVED. DEALERSHIP CAN NOT REPLICATE THE ISSUE AND AS A RESULT HAS NOT SOLVED THE PROBLEM. PROBLEM HAS BEEN WITNESSED BY THREE DIFFERENT PASSENGERS. A SECONDARY STALLING ISSUE OCCURS BETWEEN 1200-1800 WITH LIGHT GAS PEDDLE PRESSURE. IN THIS CASE, THE CAR HAS A SMALL PAUSE OR DECREASE IN POWER. DOWN SHIFTING AND ACCELERATING ELIMINATES THE PROBLEM. *TR

HIGH PRESSURE FUEL PUMP FAILED TRAVELING 60MPH, CAR BEGINS TO STUMBLE (MORE OFTEN THEN EVERY HUNDRED MILES-NOW LESS THAN EVERY 5 MILES), ENGINE ALMOST DIES OUT MULTIPLE TIMES, RPM DROPS TO NEAR ZERO, CHECK ENGINE LIGHT TURNS ON, HUNDREDS OF MINI METAL FLAKES FOUND IN FUEL SYSTEM/FUEL CANISTER . CAR DRIVEN TO DEALER (SHOWED PICTURE OF METAL IN FUEL CANISTER). HAMILTON IMPORTS (VW DEALER) HAD INITIAL TECH ON 081412 DIAGNOSIS PROBLEM AS "NORMAL FOR DIESEL FUEL." CALLED 081512 TO SERVICE MANAGER JOHN, LEFT MESSAGE, HE REPLIED STATING METAL IN FUEL IS "NORMAL." ON 081612 EMAIL VW OF AMERICA, IN REGARDS TO THE PROBLEM, CALL FROM SERVICE ADVISER ON 081712 AND ARE LOOKING FURTHER INTO THE PROBLEM. LATER THAT DAY, CALLED SERVICE ADVISER, THEY ORDERED A COMPLETE FUEL SYSTEM AND APOLOGIZED FOR THE INITIAL DELAY AND NOT FIXING THE CAR CORRECTLY. RECEIVED A CALL FROM THE DEALER, 082812, THE CAR IS READY FOR PICKUP. A COMPLETE NEW FUEL SYSTEM WAS INSTALLED (INJECTORS, HIGH PRESSURE FUEL PUMP(FAILED), FUEL RAIL, ELECTRIC FUEL PUMP IN TANK, ALL PIPING). *TR
