DT: THE CONTACT STATES THAT THE VEHICLE IS A 2001.5 VOLKSWAGEN PASSAT. THERE IS A PROBLEM WITH THE WINDOWS FOGGING. THIS OCCURS WHEN THE TEMPERATURE IS AROUND 50 DEGREES OR LESS. THE FOG WILL APPEAR ON THE WINDOW AFTER THE VEHICLE IS STARTED. SOMETIMES THE FOG WILL APPEAR AFTER THE CONTACT WAS DRIVING. IT WILL OCCUR WITHER OR NOT THE HEATER OR FAN TURNED ON. THE PROBLEM SEEMS TO BE LESS SEVERE ONCE THE VEHICLE WAS HEATED . THE ONLY WAY THE FOG WILL GO AWAY IS IF THE AIR CONDITIONER IS TURNED ON HIGH. SHE HAS ALREADY TAKEN IT TO THE DEALERSHIP TWICE, EACH TIME THEY DID A PRESSURE CHECK TO THE HEATER CORE , BUT NO REPAIRS WERE MADE. SHE IS TAKING IT BACK AGAIN TO THE DEALER. THERE WAS A PREVIOUS PROBLEM WITH THE RADIATOR LEAKING. THE RADIATOR WAS REPLACED ON OCTOBER 4, 2005. THE FOG PROBLEM APPEARS TO HAVE GOTTEN WORSE SINCE THE RADIATOR WAS REPLACED. *AK

ENGINE OIL SLUDGE- I HAVE BEEN READING ABOUT VOLKSWAGENS PROBLEM WITH 1.8 TURBO ENGINES CREATING A SLUDGE THAT RESULTS IN LOW TO NO OIL PRESSURE. I HAVE ONE OF THE CARS AFFECTED, A 2001 PASSAT. RECENTLY MY "STOP ENGINE" LIGHT CAME ON. I DID STOP AND CHANGED THE OIL AND FILTER IMMEDIATELY. I CALLED A VOLKSWAGEN DEALER AND HE SAID THAT YES MY CAR WAS COVERED FOR 8 YEARS FROM IN SERVICE DATE. HE DID SAY HOWEVER THAT TRYING TO GET EVERYONE TO "SIGN OFF" MIGHT POSE SOME DIFFICULTY WHEN THE PROBLEM ACTUALLY ARISES. MY FRIEND HAS A 2003 AUDI WITH THE SAME 1.8 T AND HE HAS HAD HIS CAR IN FOR THIS PROBLEM TWICE. I THINK THERE NEED TO SOMETHING FROM A GOVERNMENT AGENCY TO DOCUMENT THIS PROBLEM AND HOLD VOLKSWAGEN ACCOUNTABLE. I CAN'T BELIEVE THAT THEY ARE STILL ALLOWED TO MAKE THESE SAME ENGINES. *JB

THE CHECK ENGINE LIGHT CAME ON WITH A MESSAGE DISPLAY OF "EMISSIONS WORKSHOP!" AROUND 73K MI. THE CAR DEALER I BOUGHT IT FROM THOUGHT IT MIGHT BE THE O2 SENSORS, BUT IT TURNED OUT NOT BE TO. I TOOK IT TO THE LOCAL VW DEALER AND THEY TOLD ME THAT IT WAS A "RECALL/SERVICE BULLETIN" PROBLEM OF SOME SORT SO THEY RESET MY ONBOARD COMPUTER. THE CHECK ENGINE LIGHT CAME ON AGAIN WITH THE SAME MESSAGE SHORTLY THERE AFTER. I TOOK IT IN TO THE VW DEALER AGAIN AND THEY REPLACED BOTH OF MY CATALYTIC CONVERTERS (WHICH WERE COVERED BY THE VW EMISSIONS WARRANTY). THIS SEEMED TO HAVE RESOLVED THE PROBLEM. (THE PROBLEM OCCURRED THE SAME DAY I PURCHASED THE VEHICLE SO IT WOULD BE A GOOD ASSUMPTION THAT THIS PROBLEM HAD OCCURRED BEFORE I ATTAINED THE VEHICLE). *NM

WE HAD TO HAVE THE VEHICLE TOWED TO THE NEAREST VOLKSWAGEN DEALER WHERE IT TOOK A COMPLETE ENGINE TEARDOWN AND OIL PUMP REPLACEMENT. THE VEHICLE HAD ONLY 40,000 MILES ON IT AND HAD BEEN MAINTAINED WELL. THIS OCCURRED WITHOUT WARNING AND COULD HAVE RESULTED IN STRANDING A WOMAN OR CHILDREN ALONE. NO DEATHS OCCURRED, HOWEVER COMPLETE ENGINE FAILURE AT HIGHWAY SPEEDS COULD HAVE RESULTED IN LOSS OF CONTROL OF VEHICLE, LEADING TO SAME.

ENGINE LIGHT CONTINUALLY GOES ON AND OFF, WHEN BLINKING ON, THE CAR SHAKES, AS IF IT IS ABOUT TO STALL, AND A BAD ODOR EMITS. WHEN DRIVING , THE CAR WOULD NOT EXCEED 20-30 MPH, EVEN WHEN THE GAS PEDAL WAS TO THE FLOOR. BROUGHT THE CAR TO VW FIRST TIME, THEY SAID THE LIGHT CAME ON BECAUSE THE CAR WAS IDLE FOR A DAY OR SO. THE 2ND TIME, AFTER GOING TO AN INDEPENDENT REPAIR SHOP AND HAVING ALL THE PLUGS REPLACED AND A COMPLETE TUNE-UP, SAME THING HAPPENED THE NEXT DAY. INDEPENDENT SHOP SAID THE ONLY OTHER THING WAS THE IGNITION COILS AND THAT THEY WERE EXPENSIVE. CALLED VW DEALERSHIP(CAR IS ON EXTENDED WARRANTY-LESS THAN 30 THOUSAND MILES & A 2001), WAITED 9 DAYS BEFORE THEY COULD LOOK AT THE CAR, HOWEVER, THE ENGINE LIGHT WAS OUT AGAIN. I EXPLAINED TO THEM THE PROBLEM, AND ALL THEY SAID WAS THAT VW DOES NOT HAVE A RECALL ON THE IGNITION COILS, THEY REPLACED THE NEWLY PURCHASED PLUGS AGAIN, AND SAID THERE WAS NOTHING WRONG WITH THE COILS??? COST ME $261.00 PLUS A RENTAL CAR, BUT THERE WAS NOTHING WRONG.*AK

I OWN A 2001 1.8 TURBO VW PASSAT WITH GIVE OR TAKE 57,000 MILES. THE 1.8 TURBO HAS AN ISSUE WITH OIL SLUDGE. WHILE RESEARCHING THIS ISSUE I HAVE DISCOVERED THAT THIS IS NOT AN UNCOMMON PROBLEM WITH THE 1.8 TURBO AND HAVE CONCLUDED THAT THIS ISSUE SEEMS TO BE A MANUFACTURING DEFECT. ACCORDINGLY, VW HAS EXTENDED THE POWER TRAIN WARRANTY. I HAVE RECORDS SHOWING THAT ALL OF MY OIL CHANGES WERE DONE WITHIN A TIMELY MANNER. HOWEVER IN TWO INSTANCES I EXCEEDED THE "RECOMMENDED MAINTENANCE": IN THE FIRST CASE IT WAS BY 26 MILES AND IN THE SECOND CASE IT WAS APPROXIMATELY 290 MILES. IF VW HAS DENIED MY CLAIM DUE TO THOSE SITUATIONS, THEY SHOULD NOT STATE IN THE WARRANTY THAT THE OWNER FOLLOW THE "RECOMMENDED MAINTENANCE" SCHEDULE BUT THAT THE OWNER SHOULD FOLLOW A "REQUIRED MAINTENANCE" SCHEDULE. I WOULD ALSO LIKE TO POINT OUT THAT A 2001 CAR, THAT COST OVER $22,000, THAT HAS BEEN TAKEN CARE OF, AND HAS LESS THAT 60,000 MILES, SUCH AS MINE, SHOULD NOT HAVE ENGINE FAILURE. EVEN IF I WENT OVER THE "RECOMMENDED MAINTENANCE" BY 500 OR 700 MILES, WHICH WAS NOT THE CASE, THE ENGINE SHOULD NOT GIVE OUT. VW NEEDS TO TAKE ACCOUNTABILITY FOR THIS ISSUE. I WOULD ALSO LIKE TO POINT OUT THAT I NEVER RECEIVED NOTIFICATION FROM VWOA REGARDING THE OIL SLUDGE ISSUE. I HAVE ALL OF MY RECORDS STATING THAT I HAVE PERFORMED THE "RECOMMENDED MAINTENANCE" NOT REQUIRED MAINTENANCE, IN A TIMELY MANNER. YET VW HAS DENIED MY CLAIM TO COVER THE ENGINE UNDER WARRANTY. *AK

Status: closed (inferred from source dates) · Electrical System; Engine And Engine Cooling
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.

STRICKLAND OF RALEIGH, NC, SUBMITTED A PETITION REQUESTING THAT THE AGENCY INVESTIGATE THE PERFORMANCE OF THE IGNITION COIL PLUGS ON MODEL YEAR (MY) 2000-2003 VOLKSWAGEN JETTA, GOLF AND PASSAT SEDANS.THE PETITIONER ALLEGES THAT HE HAD EXPERIENCED MULTIPLE STALLING EVENTS AS A RESULT OF ONE OR MORE IGNITION COIL PLUGS MALFUNCTIONING ON HIS 2002 VW JETTA SEDAN.AS A RESULT OF THE ENGINE STALLING, THE PETITIONER EXPERIENCED A LOSS OF POWER STEERING AND INCREASED BRAKING EFFORTS WHEN HE PULLED THE VEHICLE OVER TO THE SIDE OF THE ROAD TO CONTROL THE VEHICLE.AFTER A FEW MINUTES PARKED ON THE SHOULDER HE WAS ABLE TO RESTART THE VEHICLE ALTHOUGH THE ENGINE OPERATED AT REDUCED POWER.VW ISSUED A CUSTOMER SATISFACTION CAMPAIGN (CSC) ON JANUARY 31, 2003 TO INSTRUCT THEIR DEALERSHIPS TO INSPECT THE VEHICLES FOR ANY MALFUNCTIONING IGNITION COIL PACKS AND TO REPLACE THEM AT NO COST TO THE CONSUMER.CONSUMERS WERE NOTIFIED TO BRING THEIR VEHICLES TO THEIR DEALERSHIPS VIA OWNER LETTERS MAILED OUT ON JUNE 6, 2003.WHILE VW INITIALLY INSTRUCTED THE DEALERSHIPS TO ONLY REPLACE THE MALFUNCTIONING IGNITION COIL PACKS, A REVISED CSC WAS ISSUED TO DEALERSHIPS IN DECEMBER 2003 AND JANUARY 2004, INSTRUCTING DEALERSHIPS TO REPLACE ALL IGNITION COIL PACKS REGARDLESS OF THEIR PERFORMANCE.A REMINDER TO THE DEALERSHIPS WAS SENT BY VW ON APRIL OF 2004.ALTHOUGH THE CONCERNS OF THE PETITIONER COULD THEORETICALLY CREATE A SAFETY PROBLEM, THE RISK IS VERY SMALL, DUE TO THE ENGINE STILL RUNNING ON EITHER 3, 5, OR 7 CYLINDERS.THERE ARE NO REPORTED CRASHES OR INJURIES DUE TO THE ALLEGED DEFECT.ONCE DRIVERS ARE AWARE OF THE PROBLEM (LOSS OF POWER DUE TO ONE OF THE IGNITION COIL PACKS MALFUNCTIONING), DRIVERS ARE ABLE TO TAKE PRECAUTIONARY AND COMPENSATORY MEASURES AND STILL MAINTAIN CONTROL OF THEIR VEHICLES.IN ADDITION, FOUR FIRES WERE REPORTED TO ODI.THESE WERE IGNITION COIL BURNOUTS WITH NO ADDITIONAL DAMAGE TO THE VEHICLE AND WERE LOCALIZED ON TOP OF THE ENGINE. DURING THE LAST 24 MONTHS THE NUMBER OF STALL AND DRIVABILITY COMPLAINTS REPORTED TO ODI HAS GREATLY DIMINISHED FROM A PEAK OF 195 IN JANUARY OF 2003 TO ONLY 3 IN AUGUST OF 2005.THIS COINCIDES WITH THE CSC RELEASED BY VW.A SAFETY-RELATED DEFECT TREND HAS NOT BEEN IDENTIFIED AT THIS TIME AND FURTHER USE OF AGENCY RESOURCES DOES NOT APPEAR TO BE WARRANTED.THE CLOSING OF THIS INVESTIGATION DOES NOT CONSTITUTE A FINDING BY NHTSA THAT NO SAFETY-RELATED DEFECT EXISTS.THE AGENCY RESERVES THE RIGHT TO TAKE FURTHER ACTION IF WARRANTED BY THE CIRCUMSTANCES.

THIS INVESTIGATION INVOLVES THE VOLKSWAGEN (VW) PASSENGER SUPPLEMENTAL INFLATABLE RESTRAINT (PSIR) LID UTILIZED IN MY 1998-2002 VW PASSAT.THE PSIR LID MAY DETACH FROM THE INSTRUMENT PANEL DURING AIR BAG DEPLOYMENT.THE OFFICE OF DEFECTS INVESTIGATION (ODI) OF THE NATIONAL HIGHWAY TRAFFIC SAFETY ADMINISTRATION (NHTSA) OPENED THE PRELIMINARY EVALUATION ON MAY 23, 2003 TO DETERMINE WHETHER ALLEGED PSIR LID DETACHMENT PRESENTS AN UNREASONABLE SAFETY RISK TO PASSENGERS IN THE VEHICLE.ODI?S INVESTIGATION REVEALS THAT DETACHMENT OF THE PSIR LID DURING AIR BAG DEPLOYMENT MAY OCCUR FOR TWO REASONS: 1) THE SHAPE OF THE PSIR LID, AND THE LENGTH OF THE ATTACHING TETHER, MAY SNAG THE AIR BAG DURING DEPLOYMENT APPLYING ADDITIONAL PRESSURE ON BOLTS THAT FASTEN THE LID TO THE INSTRUMENT PANEL (IP); AND/OR 2) THE ORIGINAL PSIR LID DESIGN (SUBJECT VEHICLES) UTILIZED SIX GRADE 4.8 MM CARBON STEEL TACK WELD BOLTS WHICH MAY NOT BE AS STRONG AS THE NEW DESIGN PSIR LID CONSISTING OF SIX GRADE 8.8 MM CARBON STEEL PRESS BOLTS THAT ARE HEAT TREATED.ODI CONCLUDES THAT DETACHMENT OF THE PSIR LID IS A DEFECT BECAUSE THE LID SHOULD REMAIN ATTACHED TO THE IP AFTER DEPLOYMENT OF THE AIRBAG.HOWEVER, AFTER ANALYZING VW?S RESPONSES, AND TEST DATA COLLECTED BY VW AND FAURECIA, THE PSIR LID SUPPLIER, ODI BELIEVES THAT FURTHER INVESTIGATION WOULD NOT LIKELY IDENTIFY A SAFETY-RELATED DEFECT TREND BECAUSE A DETACHED PSIR LID AND PARTS DO NOT PROJECT TOWARDS A PASSENGER DURING DEPLOYMENT OF THE AIRBAG.THE TEST DATA SHOWS THAT THE AIRBAG PUSHES A DETACHED PSIR LID UPWARDS INTO THE WINDSHIELD DURING DEPLOYMENT, AND AWAY FROM THE PASSENGER COMPARTMENT.IT IS HIGHLY UNLIKELY THAT A PASSENGER WOULD CONTACT THE PSIR LID OR ASSOCIATED PARTS DURING AIR BAG DEPLOYMENT.THEREFORE THIS ENGINEERING ANALYSIS (EA 03-020) IS CLOSED.THE CLOSING OF THIS INVESTIGATION DOES NOT CONSTITUTE A FINDING BY NHTSA THAT A SAFETY-RELATED DEFECT DOES NOT EXIST.
