2004 VW PASSAT 1.8T. UPON STARTING CAR, CHECK ENGINE LIGHT CAME ON. TOOK TO DEALER, AUTOBARN OF EVANSTON (IL) WHO REPLACED THERMAL SENSOR FOR $500. LESS THAN 2 MILES AFTER LEAVING DEALER, CAR RAN HOT AND A/C WENT OUT, HAD TO PULL OVER TO COOL. THIS WAS NOT AN ISSUE PRIOR TO VISITING THE DEALER. RETURNED TO DEALER. DEALER REPLACED "THERMAL SWITCH" FOR $300. CAR STILL RAN HOT. DEALER NOW SAYS RADIATOR IS CLOGGED AND NEEDS TO BE REPLACED ($700+). CAR HAS BEEN SERVICED REGULARLY PER VW, RADIATOR WAS FLUSHED 4,000 MILES AGO. CAR ONLY HAS 65,000 MILES ON IT. EITHER CAR IS DEFECTIVE OR DEALER IS RIPPING ME OFF. *TR

VEHICLE: 2004 VOLKSWAGEN PASSAT GLS SEDAN WITH 2.0 TDI MOTOR PROBLEM: CHAIN DRIVEN OIL PUMP HAS SERIOUS VIBRATION. IT IS NOT ON VOLKSWAGEN'S SUGGESTED MAINTENANCE LIST OR THINGS TO CHECK DURING PREVENTABLE MAINTENANCE. THE CAST METAL CHAIN TENSIONER CRACKS AND FAILS, CAUSING LOSS OF TENSION ON THE OIL PUMP DRIVE SPROCKETS WHICH LEADS TO : 1. WEAR ON DRIVE SPROCKETS. 2. CATASTROPHIC FAILURE OF THE OIL PUMP. 3. COMPLETE LOSS OF ENGINE POWER WITHOUT WARNING AT ANY SPEED IN ANY TRAFFIC CONDITION. I DO NOT KNOW THE COMPLETE FAILURE RATE FOR THIS EQUIPMENT, BUT I DO KNOW THIS SETUP WAS SOLD ON APPROXIMATELY 20,000 2.0L TURBO DIESEL MOTORS, STAMPED BHW. THIS SETUP WAS ONLY SOLD IN NORTH AMERICA AND OTHER SIMILAR MOTORS IN EUROPEAN MARKETS HAVE A GEAR DRIVEN OIL PUMP THAT DO NOT SHOW THE FAILURE RATE BEING SEEN IN THE N.A. MARKET. VOLKSWAGEN IN NORTH AMERICA HAS DISCONTINUED MAKING THE CHAIN DRIVEN OIL PUMP, REPLACING IT WITH THE GEAR DRIVEN PUMP ORIGINALLY AVAILABLE ONLY IN FOREIGN MARKETS. VOLKSWAGEN CONTINUES TO STAND BY THAT THERE'S NO PROBLEM WITH CHAIN DRIVEN PUMP, YET THERE A NUMEROUS ACCOUNTS OF FAILING TENSIONERS, CHAINS, SPROCKETS AND BALANCE SHAFTS (HEX SHAFT HOLDING THE DRIVEN SPROCKETS) DUE TO LOSS OF TENSION AND POOR DESIGN. EVERY CHAIN DRIVEN OIL PUMP ON THE BHW MOTOR WILL FAIL. MILEAGE DOES NOT APPEAR TO BE A DETERMINATION ON WHEN THIS WILL FAIL AS REPORTS OF WEAR AND FAILURE FROM 45,000 TO 180,000 MILES ARE BEING REPORTED ON INTERNET VOLKSWAGEN DIESEL FORUMS. FOR PHOTOS OF FAILED PARTS, SEE: SEE POST #743: HTTP://FORUMS.TDICLUB.COM/SHOWTHREAD.PHP?T=233651&PAGE=50 NOTE: THIS COMPLAINT DOES NOT REFER TO THE TIMING BELT ASSEMBLY OR TIMING BELT. IT REFERS SOLELY TO THE CHAIN DRIVEN OIL PUMP AND BALANCE SHAFT ASSEMBLY ON THE BHW TYPE TURBO DIESEL MOTOR. *TR

I PURCHASED A USED 2004 VW PASSAT WITH 34K MILES IN SEPTEMBER 2007. THE CAR WAS RUNNING FILE AND HAS BEEN KEPT CURRENT WITH OIL CHANGES. ON APRIL 3, 2009, MY FIANCE WAS DRIVING US HOME FROM WORK AND A LOUD KNOCKING NOISE STARTED AND A MESSAGE DISPLAYED SAYING STOP! OIL PRESSURE LOW. THIS HAS NEVER HAPPENED BEFORE. WE WERE STILL FAR FROM HOME SO WE PULLED OVER AND TOOK A LOOK UNDER THE HOOD. THE OIL WAS LOW FOR SOME REASON, ALTHOUGH IT WAS RECENTLY CHANGED, SO WE PURCHASED A QUART TO GET US HOME. WE CONTINUED TO DRIVE HOME AND STARTING LOSING POWER AS THIS KNOCKING NOISE CONTINUED. WE DID MAKE IT HOME. THE CAR WAS TOWED FROM OUR HOME TO A VW DEALER THE NEXT DAY. WE WERE TOLD THAT THE CRANK SHAFT WAS DAMAGED DUE TO OIL SLUDGE BUILD-UP IN THE ENGINE. BASICALLY, THE ENGINE WAS SHOT AND I NEEDED A NEW ONE, WHICH WOULD COST ABOUT $4K WITH ABOUT $2K IN LABOR. THE CAR ONLY HAS 55K MILES ON IT - HOW COULD THIS HAPPEN? WE THEN WENT ONLINE AND CONDUCTED A SEARCH. WE FOUND THAT THIS IS A WELL-KNOWN PROBLEM WITH 1.8 T ENGINES BETWEEN 2003-2005. I WAS MORTIFIED. I WAS NEVER GIVEN ANY INFORMATION FROM VW ABOUT THIS ISSUE, ALTHOUGH THE CAR WAS PURCHASED USED. THE DEALER TOLD US THAT VW EXTENDED THE POWERTRAIN WARRANTY FOR TO 8 YRS DUE TO THIS ISSUE BUT WE MUST PROVIDE OIL CHANGE RECEIPTS. WE HAD NONE, BECAUSE NOT ONLY DID WE NOT HAVE ONES FROM THE PREVIOUS OWNER, BUT MY FIANCE CHANGES MY OIL AND ALTHOUGH HE USED THE REQUIRED SYNTHETIC OIL, THE DEALER TOLD US THAT THERE ARE "APPROVED BRANDS" THAT MUST BE USED. WE WERE NEVER GIVEN THIS INFO BECAUSE THE OWNER MANUAL ONLY SAYS USE 5W40 OR IF NOT AVAILABLE, USE 5W30 OIL. SO, WE ARE LEFT WITH NOTHING. IT CAN COST ANYWHERE BETWEEN $4-8K TO FIX. THE COST TO GET A NEW OR USED ENGINE PLUS LABOR IS RIDICULOUS. I'M DRIVING MY OLD HONDA THAT HAS 231K MILES WHILE MY VW SITS AT THE SHOP WAITING TO BE FIXED. I FEAR THE BILL. I PLANNED TO PURCHASE A NEW VW IN A COUPLE YEARS, BUT NOW I WILL NEVER BUY A VW AGAIN AND WILL MAKE SURE MY STORY IS HEARD!! *TR

I OWN A 2004 VW PASSAT TDI (DIESEL) WITH 64, 500 MILES ON IT. I DID NOT HAVE A FAILURE BUT I WAS SO CONCERNED ABOUT IT, THAT I HAD IT PRE- FIXED. THE PROBLEM IS THAT THE BALANCE SHAFTS IN THIS ENGINE ARE DRIVEN BY A CHAIN OFF THE MOTOR WHICH ALSO DRIVES THE OLL PUMP. THIS UNFORTUNATE DESIGN SUBJECTS THE CHAIN TO STRESSES IT CAN'T WITHSTAND. ON VARIOUS TDI FORUMS, ESPECIALLY TDICLUB.COM, THERE HAVE BEEN A SIGNIFICANT NUMBER OF CHAIN FAILURES REPORTED. WHEN THE CHAIN DRIVING THE OIL PUMP FAILS,THE ENGINE IS STARVED OF ESSENTIAL LUBRICATION AND IF IT FAILS IT CAN CAUSE CATASTROPHIC ENGINE DAMAGE AND THE ENGINE COULD SEIZE UP WHICH WOULD BE LIFE-THREATENING. RECENTLY, VW 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. SINCE, UNLIKE VW OF AMERICA, I AM UNWILLING TO PUT MY AND MY CHILD'S LIFE AT RISK, I RECENTLY PAID ALMOST $3000 TO HAVE THE BALANCE SHAFT MODULE REPLACED WITH THE GEAR DRIVEN ONE. MOST OF THE PEOPLE HAVING THIS PROBLEM ARE EXPERIENCING IT AFTER THE CAR IS OUT OF WARRANTY AND VW DONE NOTHING TO NOTIFY THE NEARLY 12, 000 OWNERS OF THESE VEHICLES. MOST OF THE PEOPLE DRIVING THESE VEHICLES HAVE NO IDEA THAT THEIR CAR IS A POTENTIAL TIME BOMB. IT IS NOT A MATTER OF IF, BUT WHEN, BECAUSE OF THE POOR DESIGN, THEY ALL WILL FAIL. I WAS FORTUNATE THAT THE PARTS WERE AVAILABLE; THERE HAS BEEN A SHORTAGE AND PEOPLE HAVE HAD TO WAIT SEVERAL WEEKS JUST FOR THE PARTS TO COME IN. IF THE PART FAILS AND DESTROYS THE ENGINE, THE COST FOR THAT REPAIR IS $8-10,000. THIS IS A SAFETY ISSUE THAT NEEDS TO BE ADDRESSED BY VW OF AMERICA AND WE NEED YOUR HELP. THANK YOU FOR YOUR CONSIDERATION. *TR THE MECHANIC INFORMED THE CONSUMER THE MODULE AND CHAIN DRIVE HAD NOT FAILED, BUT THEY WERE SHOWING SIGNS OF FATIGUE. UPDATED 04/15/09. *JB

A POTENTIAL ISSUE HAS COME TO MY ATTENTION THAT SOME ENGINE PARTS RELATED TO THE BALANCE SHAFT ASSEMBLY AND THE ENGINE OIL PUMP SYSTEM DRIVE CAN FAIL AS EARLY AS 45,000 MILES. AND IF THE FAILURE OF SAID COMPONENTS DO FAIL, SEVERE ENGINE DAMAGE CAN EASILY OCCUR FORCING THE DRIVER, AT MINIMUM, TO PAY AN UNREASONABLE AND VERY COSTLY SERVICE BILL. IF A DRIVER EXPERIENCES A SUDDEN LOSS OF POWER FROM THE ENGINE DURING A TYPICAL HIGHWAY PASS OR MERGING ON A ROADWAY, THE COST WOULD BE UNFATHOMABLE PERTAINING TO THE LOSS OF LIFE, FAR SURPASSING THE COST OF A NEW ENGINE AND THE LABOR TO INSTALL THE ENGINE. VOLKSWAGEN HAS COME UP WITH A FIX BY CHANGING THE CHAIN TO A GEAR. THEY HAVE NOT ACKNOWLEDGED THIS PROBLEM AS YET, EVEN WITH MANY OF THESE VEHICLES HAVING FAILED. IT IS JUST A MATTER OF WHEN NOT IF THIS WILL HAPPEN TO EVERY 2004 PASSAT WITH THE BHW ENGINES. I WOULD LIKE TO KNOW WHAT STEPS VOLKSWAGEN OF AMERICA IS TAKING TO INFORM 2004 AND 2005 PASSAT TDI OWNERS OF THIS PROBLEM. GOOD CORPORATE CITIZENSHIP WOULD DICTATE A PROBLEM OF THIS SEVERITY SHOULD BE COMMUNICATED TO THE OWNERS AS SOON AS POSSIBLE. THESE ENGINE FAILURES COULD LEAVE MOTORISTS STRANDED UNDER DIRE CIRCUMSTANCES. *TR

THE BALANCE SHAFT CHAIN DRIVE IN THE BOTTOM END OF OUR 2004 PASSAT TDI HAS STARTED TO MAKE NOISE. THEY WILL ALL FAIL. I AM A CAR ENTHUSIAST AND FROM WHAT I UNDERSTAND THROUGH THE PAINS OF MANY THAT HAVE ALREADY REPLACED THEIR FAILED OR FAILING CHAIN DRIVEN BALANCE ASSEMBLY, MANY BREAK APART COMPLETELY, AND CAUSE THE OIL PUMP TO QUIT TURNING AND THE ENGINE TO LOCK UP SUDDENLY. VW HAS COME UP WITH A FIX FOR THIS, TO RETROFIT A GEAR DRIVEN UNIT, BUT AS OF YET HAS NOT EVEN ACKNOWLEDGED THIS VERY SERIOUS PROBLEM THAT MORE TIMES THAN NOT MANIFESTS ITSELF IN THE 60 TO 80K MILE RANGE. THE COST TO REPAIR PROACTIVE IS ABOUT $2500, BUT IF THE ENGINE IS DAMAGED, THE COST IS ABOUT $9000. THIS IS A VERY SERIOUS SAFETY ISSUE, AND CAN CAUSE THE ENGINE TO SUDDENLY SEIZE WHILE UNDERWAY! CURRENTLY THERE IS NOT EVEN A WARNING OF ANY KIND FROM VW TO OWNERS OF THESE VEHICLES TO BE AWARE OF THIS ISSUE. IF NOT FOR AN INTERNET FORUM, FRED'S TDI CLUB.COM, I LIKE MANY OTHERS WHO STILL ARE, WOULD BE COMPLETELY OBLIVIOUS TO THIS SERIOUS AND POTENTIALLY CATASTROPHIC FAILURE. *TR

In July 2010, the Agency opened PE10-027 to investigate allegations of coil on plug (COP) ignition coil fires in MY2002-2003 VW Passat vehicles.The investigation was upgraded in January 2011 to include all MY2001-2007 4-cylinder VW Passat, gasoline, turbo-charged vehicles.Based on the analysis of VW's response, and including ODI's consumer complaints, ODI has since identified 135 unique engine fire reports attributable to the COP coils.After further review of the details as contained in each report, ODI determined that 43 of the 135 fire reports were actual fire/flame incidents, 83 fire reports were thermal events (smoke, spark, heat or wire melt), and another 9 fire reports were undetermined in severity due to the lack of information.These COP coil fires were characterized as initiated from within the COP coil circuit located at the top of the engine block and below the plastic engine cover.The fires observed were contained in the engine compartment and did not reach into the passenger compartment in contrast to those caused by an overheated catalytic converter examined in ODI?s investigation in 2007 and 2008.There were no reports of crashes or personal injury in this examination.A safety-related defect has not been identified at this time and further use of agency resources does not appear to be warranted.Accordingly, this investigation is closed.The closing of this investigation does not constitute a finding by NHTSA that a safety-related defect does not exist.The agency will monitor this issue and reserves the right to take further action if warranted by the circumstancesSee the Closing Report for additional details.
