WE HAVE A 2002 VOLKSWAGEN PASSAT STATION WAGON. SEVERAL DAYS AGO, THE AIR BAG LIGHT CAME ON STEADILY & THE CAR WAS ACCELERATING SLUGGISHLY. WE TOOK IT INTO THE DEALERSHIP THE FOLLOWING DAY. THERE WAS A CRACK IN THE POLLEN FILTER HOUSING WHICH HAD ALLOWED RAINWATER TO TRACK INTO THE PASSENGER COMPARTMENT, UNDER THE CARPETS. A NUMBER OF KEY ELECTRONIC MODULES ARE IN THIS LOCATION, INCLUDING THE TRANSMISSION CONTROL MODULE AND THE COMFORT CONTROL MODULE. THESE UNITS HAD BEEN DESTROYED BY THE POOLING WATER AND WILL HAVE TO BE REPLACED. THE DEALERSHIP TELLS US THAT THIS HAS BEEN A COMMON PROBLEM WITH PASSATS; FURTHER RESEARCH ON THE INTERNET REVEALS A LARGE NUMBER OF PEOPLE WHO'VE HAD SIMILAR PROBLEMS (SEE HTTP://WWW.THEAUTOBAHN.COM/FORUM/SHOWTHREAD.PHP?T=12789&PAGE=1&PP=10). I BELIEVE THAT THIS IS A SERIOUS DEFECT WITH PASSATS THAT CARRIES RISK TO DRIVERS AND PASSENGERS OF THESE CARS. *NM

DT*: THE CONTACT STATED WHILE IN THE DRIVEWAY, THE BRAKE PEDAL WOULD NOT DEPRESS AND THE VEHICLE WOULD NOT STOP. THE VEHICLE WAS PUT IN NEUTRAL AND THE PARKING BRAKE WAS APPLIED. THE CONTACT WAITED FOR THE THERMOSTAT ON THE VEHICLE TO GO ABOVE FREEZING THEN TOOK THE VEHICLE TO THE DEALERSHIP. THE DEALERSHIP DETERMINED THE DRAIN HOLES IN THE BATTERY COMPARTMENT HAD FILLED WITH ROAD DEBRIS. THIS CAUSED WATER TO GET TRAPPED IN THE COMPARTMENT AND FREEZE. THE MASTER VACUUM FOR THE BRAKES IS LOCATED IN THIS COMPARTMENT, AND THIS FREEZING CAUSED THE FAILURE. THE DEBRIS WAS CLEARED OUT AND THE MASTER VACUUM AND OTHER COMPONENTS WERE REPLACED. *AK

I OWN A 2002 VW PASSAT V6 GLX WITH 42,700 MILES. WITHIN THE PAST 2 MONTHS AN INTERMITTENT PROBLEM STARTED WITH VERY STRONG GASOLINE FUMES COMING FROM THE CAR AFTER THE TANK IS FILLED AND THE CAR IS PARKED IN A RESIDENTIAL GARAGE. THE GAS TANK IS FILLED UNTIL THE FIRST CLICK OFF OF THE GAS NOZZLE ( AT SEVERAL DIFFERENT GAS STATIONS). THE GASOLINE FUMES ARE VERY STRONG, REQUIRING THAT THE GARAGE DOORS BE LEFT PARTIALLY OPEN TO REDUCE THE FUMES TO A TOLERABLE LEVEL. NO FUEL DRIPS FROM THE VEHICLE. THE FUMES SEEM TO BE COMING FROM THE RIGHT REAR OF THE CAR. FUMES CAN SOMETIMES BE SMELLED BRIEFLY OUTDOORS WHEN THE VEHICLE'S GAS TANK IS FULL. THE FUMES STOP AFTER THE TANK LEVEL IS DOWN TO ABOUT 3/4 TANK. THE PROBLEM RECURS CONSISTENTLY NOW FOR ME EVERYTIME THE VEHICLE IS REFUELED. I BROUGHT THE VEHICLE TO THE LOCAL VW DEALER ON 11/5/05. THEY PRESSURED TESTED THE VEHICLE'S FUEL SYSTEM WITH ARGON AND REPORTED THAT THEY CAN FIND NO FUEL LEAK OR DUPLICATE THE PROBLEM WITH A FULL TANK OF GAS. THE SERVICE MANAGER CONTACTED VW TECHNICAL ASSISTANCE. I BROUGHT THE VEHICLE IN ON 12/15/05 WITH A HALF TANK OF FUEL AS REQUESTED. THE SERVICE TECHNICIANS, AS RECOMMENDED BY VW TECHNICAL ASSISTANCE, REMOVED THE GAS TANK AND WEIGHED THE CHARCOAL CANISTER TO DETERMINE IF ADEQUATE CHARCOAL WAS PRESENT. THE CHARCOAL CANISTER WAS WITHIN FACTORY SPECIFICATIONS. THE SERVICE TECHNICIANS REINSTALLED THE SAME PARTS AND THEN FILLED THE GAS TANK. THEY THEN PRESSURE TESTED THE VEHICLE'S FUEL SYSTEM WITH ARGON OVERNIGHT, LEAVING THE VEHICLE IN THE SERVICE BAY. THEY COULD NOT DETECT ANY FUEL LEAKS OR REPRODUCE THE PROBLEM. VW TECHNICAL ASSISTANCE REPORTEDLY TOLD THE TECH'S THAT THEY HAD DONE ALL THAT WAS POSSIBLE AND THAT THERE WAS NOTHING ELSE TO DO. THE SERVICE MANAGER ACKNOWLEDGED THAT THEIR SERVICE BAY IS QUITE LARGE AND VENTILATED SO THAT THE CONDITIONS DO NOT DUPLICATE HAVING THE VEHICLE IN A RESIDENTIAL GARAGE. A FIRE RISK AND FUME EXPOSURE REMAIN. *JB

I WENT TO TURN ON 2002 PASSAT VOLKSWAGEN A COUPLE DAYS AGO AND A FLASHING "STOP" CAME ON. I CALLED MY DEALER AFTER CHECKING THE MANUAL AND THEY SAID IT SOUNDED LIKE A PROBLEM WITH THE OIL PICK UP TUBE AND FOR ME NOT TO TURN MY CAR BACK ON BECAUSE IT COULD RUIN THE ENGINE. SO I HAD MY CAR TOWED TO THE DEALER AND THEY INFORMED ME THAT IT IS ONLY UNDER WARRANTY IF I CAN SUPPLY THEM WITH EVERY RECEIPT FROM OWNING THE CAR. I HAVE MISPLACED TWO SO NOW THEY WILL NOT COVER THIS AND IS COSTING ME AROUND $950.00 TO GET THIS FIXED. I HAVE ALWAYS CHANGED MY OIL ON TIME. THIS SEEMS TO BE THERE WAY OF SCREWING THERE SO CALLED VALUED CUSTOMERS. I WAS ON A WEB SITE (MYVWLEMON.COM) AND FOUND NUMEROUS OF PASSAT OWNERS WITH THIS EXACT PROBLEM AND OUT COME. WHY IS THE CONSUMER RESPONSIBLE FOR A POORLY DESIGNED ENGINE? THE HEAT OF THE 1.8L TURBO IS BREAKING THE OIL DOWN CREATING SLUDGE. THEY OBVIOUSLY KNOW OF THIS PROBLEM BECAUSE THEY ISSUED A WARRANTY EXTENSION. HOWEVER, VW OF AMERICA WILL ONLY COVER THE WARRANTY IF THE OWNER CAN PROVIDE EVERY SINGLE RECEIPT, SOMETHING THEY KNOW THAT VERY FEW PEOPLE CAN DO ESPECIALLY IF SOME CHANGE THEIR OWN OIL. THIS IS JUST ONE OF THE PROBLEMS THAT I HAVE DEALT WITH SINCE I BOUGHT BY PASSAT BRAND NEW. CHECKING THE WEBSITE ALSO TELLS ME THIS MAY NOT BE THE LAST OF MY PROBLEMS. *JB

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.

DURING THIS INVESTIGATION, VOLKSWAGEN OF AMERICA (VW) IDENTIFIED A PROBLEM WITH WATER ACCUMULATION IN THE FRESH AIR PLENUM THAT COULD, IN CERTAIN CIRCUMSTANCES, RESULT IN REDUCED BRAKE POWER ASSIST IN MODEL YEAR (MY) 2002 PASSAT VEHICLES.VW INDICATED THAT PROBLEM IS CAUSED BY LEAVES AND OTHER DEBRIS CLOGGING THE PLENUM DRAINS, WHICH MAY RESULT IN WATER FILLING THE PLENUM TO THE LEVEL OF THE BRAKE BOOSTER AIR INTAKE.THE BOOSTER AIR INTAKE IS LOCATED IN THE FRESH AIR PLENUM IN THE MY 2002 PASSAT VEHICLES, BUT NOT IN THE MY 2001 OR 2003 VEHICLES WHICH DRAW BOOSTER AIR FROM THE CABIN.VW TESTING SHOWED THAT BRAKE ASSIST COULD BE REDUCED IF WATER ENTERS THE BOOSTER AND FREEZES.VW IS ADDRESSING THE PROBLEM WITH A SERVICE CAMPAIGN, WHICH BEGAN IN AUGUST 2007.THE FRESH AIR PLENUM IN THE SUBJECT VEHICLES IS AN ENCLOSED SPACE AT THE BASE OF THE WINDSHIELD FROM WHICH THE VEHICLE VENTILATION SYSTEM DRAWS THE FRESH AIR SUPPLY VIA A POLLEN FILTER.RAIN WATER THAT FLOWS OFF THE WINDSHIELD INTO THE PLENUM IS DRAINED THROUGH TWO VALVES LOCATED BELOW THE BATTERY AND BRAKE BOOSTER.STRAINERS AT THE BASE OF THE WINDSHIELD AND IN THE PANEL COVERING THE TOP OF THE PLENUM BLOCK LEAVES, PINE NEEDLES AND OTHER DEBRIS.OVER TIME, DEBRIS MAY ENTER THE PLENUM THROUGH OPENINGS IN THE PLENUM PANEL OR AROUND THE HOOD HINGES.IF CLOGGED DRAINS ALLOW APPROXIMATELY 3-4 GALLONS OF WATER TO ACCUMULATE IN THE PLENUM, THE WATER MAY ENTER THE BOOSTER THROUGH THE AIR INTAKE.WATER ACCUMULATION IN THE PLENUM MAY ALSO RESULT IN COMPLAINTS OF WET CARPETS IN THE VEHICLE INTERIOR IF THE WATER REACHES THE LEVEL OF THE FRESH AIR INTAKE/POLLEN FILTER. VW STATED THAT ITS TESTING SHOWED THAT BRAKE PERFORMANCE AND ACTUATING FORCE (I.E., PEDAL EFFORT) ARE NOT AFFECTED WHEN THE BOOSTER IS FILLED WITH THE MAXIMUM AMOUNT OF WATER POSSIBLE (UP TO THE HEIGHT OF THE BOOSTER ENGINE VACUUM CONNECTION, THROUGH WHICH WATER DRAWN INTO THE BOOSTER IS EVACUATED).VW'S TESTING SHOWED THAT BRAKE PERFORMANCE AND ACTUATING FORCE COULD BE AFFECTED BY WATER FREEZING IN THE BOOSTER.HOWEVER, WHEN TESTED WITH RELATIVELY LOW VOLUMES OF FROZEN WATER IN THE BOOSTER, VW SHOWED THAT THE EFFECTS WERE SIGNIFICANTLY LESS SEVERE THAN FOR CONDITIONS THAT RESULT IN A COMPLETE LOSS OF VACUUM ASSIST.WHILE VW INDICATED THAT THE EFFECTS WOULD BE MORE SEVERE WITH GREATER VOLUMES OF FROZEN WATER, IT MAINTAINED THAT THE CHANCES OF THIS OCCURRING WERE REMOTE AND WOULD BE READILY DISCERNABLE TO THE DRIVER UPON THE INITIAL BRAKE APPLICATION AFTER VEHICLE START-UP.ODI'S ANALYSIS OF COMPLAINTS AND WARRANTY DATA SHOWED DISPROPORTIONATE CONCENTRATIONS IN WINTER MONTHS AND IN NORTHERN STATES WITH COLDER WINTER CLIMATES. ODI IDENTIFIED THREE MINOR CRASHES RELATED TO THE ALLEGED DEFECT IN MY 2002 PASSAT VEHICLES.TWO OF THE CRASHES OCCURRED INGARAGES/DRIVEWAYS AND THE THIRD OCCURRED IN A DEALER SERVICE GARAGE.THERE WERE NO INJURIES ALLEGED IN THE CRASHES BUT A FOOT INJURY WAS ALLEGED IN A FOURTH INCIDENT WHERE EXCESSIVE BRAKE EFFORT REQUIRED DURING A HARD STOP. VOLKSWAGEN IS CONDUCTING A SERVICE CAMPAIGN TO REMEDY THIS CONDITION IN MY 2002 PASSAT AND AUDI A4 AND A6 VEHICLES.THE REMEDY PROCEDURE REQUIRES VW DEALERS TO INSPECT, CLEAN AND MODIFY THE AIR PLENUM DRAIN, AS WELL AS MODIFY THE SUNROOF DRAIN (IF EQUIPPED) AND INSTALL AN IMPROVED SEAL FOR THE POLLEN FILTER.IN ADDITION, VW HAS AGREED TO PROVIDE THE FOLLOWING INFORMATION TO ODI1. QUARTERLY COMPLETION REPORTS FOR ONE YEAR; AND 2. PROMPTLY REPORTING ALL CRASHES ATTRIBUTED TO THE ALLEGED DEFECT. THIS INVESTIGATION IS CLOSED BASED UPON THE ACTIONS TAKEN BY VW.THE CLOSING OF THIS INVESTIGATION DOES NOT C

BY LETTER RECEIVED ON JUNE 24, 2005, MR. RONALD M. 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.
