2005 VOLKSWAGEN PASSAT Engine And Engine Cooling Problems

TL* THE CONTACT OWNS A 2005 VOLKSWAGEN PASSAT. THE CONTACT STATED THAT THE VEHICLE STALLED WHILE DRIVING 30 MPH. THE VEHICLE WAS TOWED TO THE DEALER FOR A DIAGNOSIS. THE DEALER STATED THAT THEY HAD TO REPLACE THE ENGINE. THE VEHICLE HAD NOT BEEN REPAIRED. THE MANUFACTURER WAS CONTACTED STATED THAT THEY WERE NOT RESPONSIBLE FOR THE REPAIRS BECAUSE THE VEHICLE WAS NOT UNDER RECALL. THE FAILURE AND CURRENT MILEAGES WERE 125,000. THE VIN WAS NOT AVAILABLE.

I WAS DRIVING ON HIGHWAY WHEN THE ALARM MESSAGE "OIL PRESSURE LOW: STOP ENGINE" CAME ON. I GOT OFF THE SIDE OF THE ROAD AND THE ENGINE LOCKED UP. BENT VALVES, BROKEN PISTON SHAFT, ENGINE NEEDS REPLACED. I'VE SEEN THIS SO MANY TIMES ON THE INTERNET AS I'VE BEEN LOOKING INTO MY OPTIONS SINCE THEN. VOLKSWAGEN WILL DO NOTHING TO HELP NOR TAKE RESPONSIBILITY. THEY OFFERED ME $1000 TOWARD A NEW VOLKSWAGEN. SERIOUSLY? I HAVE MAINTAINED THE VEHICLE. THEY KNOW THERE IS A PROBLEM WITH THESE CARS AND AS FAR AS I'M CONCERNED, IT IS CRIMINAL TO SELL THESE WITHOUT RECALLING TO FIX THE PROBLEM. IF I WASN'T ABLE TO GET OFF THE HIGHWAY, OUTSIDE OF CHICAGO, MY PASSENGER AND I WOULD HAVE BEEN SMASHED WITH COUNTLESS OTHER INJURIES. I DIDN'T STOP THE CAR ONCE I GOT OFF THE ROAD, IT STOPPED ITSELF. VOLKSWAGEN NEEDS TO BE ACCOUNTABLE FOR THEIR...

2.0L VW PASSAT TDI HAD A RATTLING, VIBRATING CHAIN NOISE FROM THE OIL PUMP BALANCE SHAFT MODULE IN THE OIL PAN. THE OIL PUMP CHAINS/SPROCKETS/TENSIONERS WERE WORN AND CAUSED NOTICEABLE VIBRATION AND RATTLING NOISE FOR THOUSANDS OF MILES; HOWEVER, IT WAS DIFFICULT TO DIAGNOSE. WE HAD THE ENTIRE OIL PUMP ASSEMBLY REPLACED BY A VW DEALERSHIP AT APPROXIMATELY 120,000 MILES WITH OEM GEAR DRIVEN PUMP WHICH INCLUDES THE BALANCE SHAFTS AND OIL PUMP. IT WAS A $3700 REPAIR TO EXCHANGE THE ORIGINAL OIL PUMP WITH THE GEAR DRIVEN PUMP. NOT A CHEAP SERVICE. THE SOUND BEFORE AND AFTER THE MODULE CHANGE WAS MUCH IMPROVED BECAUSE THE GEARS ARE QUIETER. THE REPLACEMENT GEAR DRIVEN OIL PUMP/BALANCE SHAFT ASSEMBLY USES A SIMILAR BALANCE SHAFT BUT WITH A DIFFERENT OIL PUMP AND GEAR DRIVE. THE GEAR DRIVE SMOOTHES OUT STRESS ON THE OIL PUMP HEX SHAFT SO RUNS MUCH BETTER. IN SUMMARY, I...

THE TDI (DIESEL) ENGINE IN THE '04 & '05 NORTH AMERICAN VOLKSWAGEN PASSATS WAS EQUIPPED WITH A CHAIN DRIVEN OIL PUMP/BALANCE SHAFT MODULE. THE CHAIN TENSIONER FAILS CAUSING THE CHAIN TO SEPARATE WHICH STOPS THE OIL PUMP AND DESTROYS THE ENGINE. IF A PERSON IS LUCKY, LIKE I WAS, AND HEARS THE CHAIN NOISE BEFORE IT FAILS, THE ENGINE CAN BE SAVED. THE FIX INVOLVES INSTALLING A NEW GEAR DRIVEN BALANCE SHAFT MODULE WHICH CONTAINS A NEW OIL PUMP. THE REPAIRS COSTS ~ $2,500 PARTS AND LABOR. VOLKSWAGEN HAS IGNORED THIS FAULT IN THE US (AND CANADA), DENYING THE PROBLEM EXISTS, EVEN THOUGH HUNDREDS OF CASES OF FAILURE HAVE BEEN DOCUMENTED. IN FACT, THE NEW DESIGN MODULES ARE CURRENTLY ON BACK ORDER AT THE VW PARTS FACTORY. THE OIL PUMP CHAIN DRIVE PROBLEM IS WITHOUT A DOUBT A DEFECT. THE FACT THAT VW RE-ENGINEERED AND REPLACED THE ORIGINAL OIL PUMP...

TL* THE CONTACT OWNS A 2005 VOLKSWAGEN PASSAT. WHILE DRIVING APPROXIMATELY 35 MPH, THE CONTACT HEARD A CLATTERING SOUND COMING FROM THE ENGINE. THE VEHICLE WAS TAKEN TO AN INDEPENDENT MECHANIC FOR ROUTINE MAINTENANCE WHERE THE MECHANIC ADVISED THAT THE CHAIN DRIVE ASSEMBLY FOR THE OIL PUMP WOULD HAVE TO BE REPLACED. THE VEHICLE WAS NOT REPAIRED. THE VIN WAS NOT AVAILABLE. THE APPROXIMATE FAILURE MILEAGE WAS 96,500.

TL- THE CONTACT OWNS A 2005 VOLKSWAGEN PASSAT TDI. THE CONTACT STATED THAT AT ENGINE STARTUP, A NOISE WAS HEARD FROM UNDER THE HOOD. THE VEHICLE WAS TAKEN TO A PRIVATE MECHANIC WHERE THE MECHANIC STATED TO THE CONTACT THAT THE OIL PUMP CHAIN WAS LOOSE. THE MANUFACTURER WAS CONTACTED BUT THE VEHICLE WAS NOT REPAIRED. THE FAILURE MILEAGE WAS 108,500 AND THE CURRENT MILEAGE WAS 109,000. KMJ

I'VE HAD TO GET MY 2005 PASSAT FIXED 3 TIMES FOR ENGINE SLUDGE ISSUES AND IT'S HAPPENING TO IT AGAIN. IT HAS COST ME NEARLY $4000 AND COUNTING. *TR

OIL PUMP FAILURE LEADING TO ENGINE FALUE. REQUIRING ENGINE REPLACEMENT.*TR

I HAVE A 2005 VW PASSAT GLS WITH APPROX 135,000 MILES. I TOOK IT IN TO GET "WINTERIZED", OIL CHANGE AND CLEAR THE ENGINE LIGHT (WHATEVER THE MISFIRE WAS FOR), AND A FACTORY RECALL ON THE ENGINE COILS. GOT ALL THAT DONE (PLUS SERPENTINE BELT REPLACED) AND WAS TOLD THAT THE ENGINE LIGHT SHOULD BE OK, IF IT COMES BACK ON...TO LET THEM KNOW ASAP. A DAY AND 1/2 LATER, THE LIGHT CAME BACK ON, AND THIS TIME, THERE WAS BARELY ANY HEAT ON IN THE CAR. TOOK IT BACK...THEY STATED THAT THE COILS NEEDED TO BE REPLACED (AGAIN) AND THAT THERE WAS AN OIL LEAK GOING INTO THE COILS & THE FUEL INJECTORS, AND THAT THE HEATER CORE NEEDED TO BE REPLACED. I HAD THE COILS AND THE 2 "FAULTY" INJECTORS REPLACED. I GOT FRUSTRATED WITH THIS DEALER AND WENT TO ANOTHER VW DEAL, FOR THEIR EVALUATION. THEY SAID...

NUMEROUS REPORTS OF VW BHW DIESEL ENGINE OIL BALANCE SHAFT / CHAIN FAILURE ARE REPORTED. VOLKSWAGEN OF AMERICA REFUSES TO ACKNOWLEDGE ANY RESPONSIBILITY FOR REPAIR DESPITE THE FACT THAT VW HAS RECOGNIZED THE ISSUE AND CHANGED THE DESIGN. FAILURE OF THE BALANCE SHAFT / CHAIN RESULTS IN IMMEDIATE LACK OF POWER CREATING A POTENTIAL LIFE SAFETY HAZARD. VW OF CANADA HAS ACKNOWLEDGED RESPONSIBILITY IN SOME DOCUMENTED CASES. VW OF AMERICA SHOULD BE COMPELLED BY GOVERNMENT AUTHORITIES TO RESOLVE THE MATTER ON BEHALF OF US CITIZENS. I AM HAVING THE REPAIR DONE PROACTIVELY TO PREVENT ANY SERIOUS SAFETY ISSUE BUT VW SHOULD STEP UP AND REIMBURSE THOSE OF US WHO HAVE PAID FOR THE EXPENSIVE REPAIR ON OUR OWN. *TR

I OWN A 2005 PASSAT TDI GLS. MY CAR HAD DEVELOPED A VERY SERIOUS NOISE CAUSED BY THE OIL PUMP CHAIN UNIT THAT WAS ORIGINALLY ON THIS VEHICLE. I DID TALK TO VW AND MY DEALER SERVICE DEPARTMENT ABOUT THE THRASHING CHAIN NOISE. I GOT POLITE DENIALS AND BLANK STARES WHEN I TOLD THEM OF THIS ISSUE. MEMBERS OF THE WWW.TDICLUB.COM DISCOVERED A VW ENGINEERED FIX FOR THE VEHICLES INVOLVED. MEMBERS WHO HAVE DRIVEN THEIR CARS BEYOND THE 80K OR SO SEEM MORE LIKELY TO HAVE THE CHAIN SNAP DURING OPERATION WHICH RENDERS THE CAR INOPERATIVE AND DANGEROUS DURING THE BREAKAGE. THE FIX IS NOT EXACTLY AN INEXPENSIVE REPAIR AS THE PARTS ALONE ARE AROUND $1500 AND THE INSTALLATION REQUIRES EXTENSIVE DISASSEMBLY OF THE VEHICLE. THE REPAIR INVOLVES REPLACING THE CHAIN DRIVEN OIL PUMP BALANCE SHAFT ASSEMBLY WITH A GEAR DRIVEN ASSEMBLY. THE BELOW LINK HAS VIDEOS/SOUND CLIPS OF MY...

TL* THE CONTACT OWNS A 2005 VW PASSAT. WHILE DRIVING 30 MPH, THE LOW PRESSURE WARNING LIGHT ILLUMINATED ON THE INSTRUMENT PANEL; WHICH INSTRUCTED HER TO DISCONTINUE OPERATION. IT THE CONTACT CHOSE TO CONTINUE OPERATING THE VEHICLE ENGINE FAILURE COULD HAVE OCCURRED. THE VEHICLE WAS TOWED TO A DEALER FOR INSPECTION. A TECHNICIAN REPLACED THE TURBO ALONG WITH THE OIL AND PICK-TUBE; TO AVOID OIL FROM ENTERING INTO THE INNER COOLER. THE CURRENT AND FAILURE MILEAGES WERE 62,000.

MY 2005 PASSAT TDI WAS LEAKING A HUGE AMOUNT OF OIL SO I TOPPED OFF THE OIL AND TOOK IT TO THE MECHANIC. HE SHOWED ME A HUGE GASH IN THE OIL PAN, RESULTING IN THE LEAK. WHEN WE TOOK THE PAN OFF THE OIL PUMP CHAIN TENSIONER AND CHAIN CAME OUT IN PIECES. THE TENSIONER BROKE AND SLAMMED THE CHAIN INTO THE OIL PAN, MAKING THE GOUGE. WE REPLACED THE OIL PAN, CHAIN, TENSIONER, AND COMPLETED AN EARLY TIMING BELT CHANGE INCLUDING A WATER PUMP. THIS WAS AROUND $2000 TOTAL. AFTER SOME RESEARCH I FOUND OUT THIS IS LIKELY DUE TO A PROBLEM WITH THE BALANCE SHAFT MODULE / CHAIN DRIVEN OIL PUMP SETUP ON THESE CARS. I FOUND OUT THAT EVEN THOUGH I SPENT $2000 FIXING THIS I MAY NEED TO COMPLETE THE SAME REPAIRS AGAIN OR REPLACE THE BALANCE SHAFT MODULE WHICH WOULD BE SEVERAL THOUSAND DOLLARS....

I HAVE A 2005 PASSAT TDI THAT HAD ITS BALANCE SHAFT MODULE AND CHAIN THAT DRIVE THE OIL PUMP FAIL AT 92,000 MILES. IT HAPPENED WHILE I WAS DRIVING ON A TWO LANE ROAD AND I HAD TO STOP THE CAR ON THE SIDE OF THE ROAD. THE MECHANIC THAT IS DOING THE JOB IS CHARGING ME $1500 FOR THE REPAIR AND THE PARTS ARE ABOUT $1300. I HAVE STARTED TO RESEARCH THIS FAILURE AND HAVE FOUND OUT THAT IT IS QUITE COMMON AND VW HAS NOT DONE A RECALL TO REPAIR THE PROBLEM THE NHTSA SHOULD LOOK INTO THIS AND FORCE VW TO RECALL THESE CARS FOR THEY ARE A SAFETY HAZARD ON THE ROAD. *TR

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...

THE BALANCE SHAFTS IN THIS ENGINE ARE DRIVEN BY A HEX SHAFT OFF THE CHAIN DRIVEN OIL PUMP. THIS UNFORTUNATE DESIGN SUBJECTS THE CHAIN TO STRESSES IT CANNOT WITHSTAND. MY OWN PASSAT HAD THE OIL PUMP AND BALANCE SHAFT REPLACED 2/16/09 WITH LESS THAN 65,000 MILES. THANKFULLY, A GOOD MECHANIC DETECTED THE PROBLEM BEFORE I HAD A CATASTROPHIC ENGINE FAILURE. A $3,500 REPAIR IS NEVER WELCOME, BUT IT WAS BETTER THAN REPLACING THE ENGINE LIKE THE VW DEALER RECOMMENDED. I DID A LOT OF RESEARCH ON THIS PROBLEM AND INQUIRED AT SEVERAL VW DEALERSHIPS AND CHOSE THE MOST EXPERIENCED MAN TO DO THE JOB. 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. PARTS WILL COST IN EXCESS...

I HAVE RECENTLY COME TO THE NEED OF HAVING TO REPLACE A CRITICAL PART OF THE ENGINE OIL SYSTEM IN MY 2005 PASSAT TDI. FOR VARIOUS REASONS, NOT THE LEAST OF WHICH IS AN INFERIOR DESIGN, THE BALANCE SHAFT ASSEMBLY ON THIS PARTICULAR ENGINE (2004-2005 MODEL YEARS) WILL CAUSE OIL FLOW TO THE ENGINE TO CEASE, DISRUPTING SAFE TRAVEL OF THE CAR IMMEDIATELY, REGARDLESS OF THE SPEED OF TRAVEL. THIS FAILURE IS EXCEPTIONALLY DANGEROUS AT HIGHWAY SPEEDS OF 70+ MPH. IF THIS FAILURE WERE TO OCCUR AT HIGHWAY SPEED, THE DRIVER WOULD NOTICE A SUDDEN DECELERATION AND A NEED TO MOVE TO THE SHOULDER ABRUPTLY. NOT ONLY WOULD THIS ENDANGER THE DRIVER AND OCCUPANTS OF SAID VEHICLE, BUT OTHER DRIVERS ON THE ROADWAY AS WELL. VOLKSWAGEN HAS YET TO ISSUE A STATEMENT, RECALL OR WARNING TO OWNERS OF THIS PARTICULAR VEHICLE, NOR IS IT MENTIONED ANYWHERE IN THE OWNER'S MANUAL...

I CURRENTLY LEASE A 2005 VW PASSAT. WARRANTY OFFERED: 5 YR/ 50,000 MILE. APPROX. NOV 7, 2008 VEHICLE DASHBOARD BEGAN TO REGISTER "STOP OIL PRESS LOW". IMMEDIATELY PULLED INTO CLOSEST GAS STATION AND PURCHASED A SYNTHETIC OIL FOR VW THINKING THIS WOULD SOLVE THE PROBLEM. ON NOV 17, 2008 DASHBOARD LIT UP AGAIN WITH SAME MESSAGE AND IMMEDIATELY BROUGHT VEHICLE INTO VISTA VW, POMPANO BCH, FLORIDA. WAS INSTRUCTED THAT ISSUE WAS POSSIBLY DUE TO FAULTY OIL PRESSURE DIP STICK CYLINDER AND NEED OF OIL CHANGE. (CYLINDER REPLACED AND OIL CHANGE COMPLETED) PRIOR OIL CHANGE WAS COMPLETED AT VISTA VW POMPANO BEACH. VW MECHANIC PLACED A CLEAR OIL CHANGE MAINT. STICKER WITH INCORRECT MILEAGE DUE AT NEXT OIL CHANGE. OIL CHANGE SHOULD HAVE OCCURRED AT 38,000 MILES VS. 45,000. VISTA VW STATED I WOULD NEED TO PAY FOR A DIAGNOSTIC TEST TO BE COMPLETED (APPROX $166.00) AS WELL AS AN HOURLY...

I HAVE NOT HAD FAILURE YET, BUT THERE ARE SEVERAL INDIVIDUALS WHO OWN THE SAME EXACT CAR I OWN, A 2005 VW PASSAT TDI. THERE IS AN ONGOING CONCERN AT SEVERAL NEWS GROUPS INCLUDING WWW.TDICLUB.COM AND OTHER DIESEL ENTHUSIAST NEWSGROUPS ABOUT THE OIL PUMP CHAIN UNIT THAT IS IN THE VW BHW 2.0 TURBODIESEL ENGINE. MANY OF THESE CARS WHEN THEY GET OUT OF WARRANTY AT 60K WILL START TO HAVE ENGINE NOISE WHICH IS INDICATIVE OF THE OIL PUMP CHAIN UNIT CHAIN WEAKENING. THIS CONDITION LEADS TO COMPLETE FAILURE WITHOUT GENERAL WARNING. THIS IS A DISASTER AWAITING TO HAPPEN. VW IN EUROPE HAS DEVELOPED A FIX FOR THIS ENGINE THAT INVOLVES INSTALLING A GEAR SYSTEM INSTEAD OF THE CHAIN AND TENSIONER SYSTEM FOR THE ENGINE BALANCING SYSTEM. THERE ARE SEVERAL EPISODES OF PEOPLE HAVING THE ENGINES FAIL WHILE ON THE ROAD. I AM CONCERNED AS AN OWNER OF THIS...

THIS REFERENCE A VERY SPECIFIC VEHICLE, I.E. NAMELY THE 2005-2005 VW PASSAT TDI (DIESEL) CAR, BOTH SEDAN AND STATION WAGON VERSION, WITH THE VW BHW ENGINE. WHAT STARTED OUT AS AN OCCASIONAL NEED TO REPLACE THE CHAIN THAT DRIVE THE OIL PUMP, BECAME A CERTAINTY THAT THE CHAIN WOULD BREAK. IF THE CHAIN BREAKS, YOU LOOSE OIL PRESSURE IMMEDIATE, AND THE ENGINE IS GOING TO SEIZE (NOT TO MENTION THE CHAIN ITSELF FLOPPING AROUND IN THE CRANK AREA WHICH COULD LODGE IN THE DRIVE SYSTEM AND DO THE SAME). IN ANY SITUATION WHERE YOU ARE ACCELERATING, THAT IS GOING TO BE CATASTROPHIC , AND CERTAINLY ANY HIGHER SPEED ON A FREEWAY/HIGHWAY BEING THE SAME) VW HAS RECOGNIZED THE ISSUE AND HAS NOW ISSUED A TSB ON THE PROBLEM, BUT HAS NOT INSTITUTED A RECALL. THE CHANGE IS TO REMOVE THE CHAIN DRIVE SYSTEM AND CONVERT THE ENGINE TO A GEAR...

I HAVE LEASED A 2005 VW PASSAT. I CHANGED MY OIL ON A REGULAR BASIS, MY MECHANIC DID NOT WRITE THE IN MILEAGE OR OUT MILEAGE WHEN HE GAVE ME MY RECEIPT. MY CAR BROKE DOWN ON THE HIGHWAY AND VW STATES THAT I NEED A NEW MOTOR DUE TO SLUDGE IN THE MOTOR. THE ARE TELLING ME MY RECEIPTS ARE NOT GOOD ENOUGH AND WON'T COVER THE MOTOR. I HAVE SEARCHED THE WEB AND SEE I'M NOT THE ONLY ONE WITH THIS PROBLEM. THE PALISADES, NY VW ARE IMPOSSIBLE TO DO BUSINESS WITH. I'M NOT GETTING A NEW MOTOR! *TR
