THE DEALER DISCOVERED THAT WATER WAS ENTERING THE BRAKE LINE, BUT NEVER INFORMED THE CONTACT OF A RECALL. INSTEAD, THE DEALER REPAIRED THE BRAKE SYSTEM AND STATED THAT IT WAS A COURTESY FROM VOLKSWAGEN. AFTER THE REPAIR, THE FAILURE RECURRED AND THE BRAKES FAILED WHILE DRIVING 30 MPH. THE CONTACT NOTICED THICK, WHITE SMOKE COMING FROM THE EXHAUST PIPE. SHE HAD TO STRIKE THE WHEEL AGAINST THE CURB IN ORDER TO STOP THE VEHICLE. THE FOLLOWING DAY, SHE TOOK THE VEHICLE TO THE DEALER AND THEY MADE REPAIRS AGAIN. THE FAILURE MILEAGE WAS 21,000.

WHEN I STARTED MY 2002 PASSAT STATION WAGON YESTERDAY, THERE WAS NO POWER ASSIST FUNCTION ON THE BRAKES. THIS WAS EXPERIENCED TWO DAYS IN A ROW, AND BRAKING WAS EXTREMELY DIFFICULT. BRAKING DISTANCE WAS GREATLY INCREASED OVER WHAT IT HAD PREVIOUSLY BEEN. THIS PHENOMENON HAPPENED WHEN I FIRST STARTED DRIVING THE VEHICLE AFTER IT WAS PARKED A WHILE. PUMPING THE BRAKES SEEMED TO IMPROVE THE EFFECTIVENESS OF THE BRAKING, BUT NEVER ENOUGH TO GIVE ME CONFIDENCE THAT I COULD STOP WHEN I NEEDED TO. I HAVE TAKEN THE CAR TO THE DEALER, AND THEY HAVE SAID THE MASTER CYLINDER NEEDS REPLACING. I PARTICIPATED IN THE AIR PLENUM RECALL AND HAD THE AIR PLENUM REPLACED ON 9/7/07. I AM SENDING IN THE PRESENT COMPLAINT AFTER READING THE NHTSA ACTION # PE07018. THE PROBLEMS WITH THE BRAKES IN COMPLAINT #PE07018 SOUND VERY MUCH LIKE MY PROBLEM, AND I THOUGHT YOU SHOULD BE AWARE OF MY SITUATION. I ALSO LIVE IN WISCONSIN WHERE WE ARE CURRENTLY HAVING A COLD WET WINTER. *TR

1) BOTH FAILURES OCCURRED IN WET CONDITIONS --- ONCE IN POURING RAIN AFTER THE CAR HAD BEEN DRIVEN FOR A WHILE, AND ONCE DURING THE FIRST DRIVE ON A COLD MORNING (JUST BELOW FREEZING) AFTER AN INCH OR TWO OF SNOW. 2) IN BOTH CASES, THE BRAKE PEDAL MOVED ONLY A LITTLE (AN INCH OR TWO PERHAPS?) AND THEN BECAME VERY HARD, NOT MOVING ANY FURTHER WITH ADDITIONAL PUSHING, AND PROVIDING VERY LITTLE BRAKING POWER (PERHAPS 5% OF NORMAL BRAKING?). FORTUNATELY BOTH INCIDENTS OCCURRED AT RELATIVELY LOW SPEED, AND THE HAND BRAKE WAS NOT AFFECTED. IN BOTH CASES, THE BRAKES WORKED NORMALLY AGAIN BY THE TIME WE HAD ORGANIZED OURSELVES TO TAKE THE CAR IN FOR SERVICE --- BOTH TIMES, THIS WAS DAYS LATER (THOUGH WE HAD NOT DRIVEN THE CAR); IN THE SECOND INCIDENT, WE LEFT THE CAR ON THE STREET OVERNIGHT BEFORE PUTTING IT IN OUR DRIVEWAY THE NEXT MORNING, AND THE BRAKES WERE STILL NOT WORKING AT THAT TIME. 3) IN THE FIRST INCIDENT (OCCURING IN AUGUST '07?), WE TOOK THE VEHICLE IN FOR SERVICE AT A SERVICE STATION, LEARNED OF A VW RECALL INVOLVING WATER LEAKING THAT COULD AFFECT THE BRAKES AND LEAK WATER INTO THE PASSENGER COMPARTMENT (WHICH WAS ALSO HAPPENING DURING HEAVY RAIN), AND THEN TOOK THE CAR TO THE DEALERSHIP (PIAZZA ACURA/VW OF ARDMORE, PA) FOR SERVICE --- THEY REPAIRED THE LEAK PROBLEM AND CLEANED THE INTERIOR, BUT I AM NOT SURE WHETHER THEY DID ANYTHING ABOUT THE BRAKES (WE MAY NOT HAVE MENTIONED THIS SPECIFICALLY TO THEM, SINCE IT WAS MENTIONED IN THE RECALL). THE CAR SEEMED FINE AFTERWARD. AFTER THE SECOND INCIDENT (ON 12/6/07), WE ARE ONCE AGAIN HAVING THE CAR CHECKED OUT AT OUR REGULAR SERVICE STATION (WE HAVE BEEN IMPRESSED BY THEIR DIAGNOSTIC SKILLS IN THE PAST). SO FAR THEY HAVE NOT IDENTIFIED ANY BRAKE PROBLEM, AND WE PLAN TO TAKE THE CAR TO THE DEALERSHIP NEXT IF OUR REGULAR STATION MECHANICS CANNOT FIND A PROBLEM THAT WOULD EXPLAIN THE BRAKE FAILURE. *TR

THE ABS CONTROL MODULE FAILED ON MY CAR CAUSING THE ABS SYSTEM AND THE ASR (ANTI-SLIP REGULATION) TRACTION CONTROL SYSTEMS TO NO LONGER FUNCTION. THIS HAPPENED WITHOUT WARNING WITH NO SIGNS LEADING UP TO THE FAILURE. THIS HAS ALSO CAUSED OTHER STRANGE ELECTRICAL ISSUES WHERE MY KEYLESS ENTRY WILL NO LONGER WORK. ALSO, THE ERROR LIGHTS CONTINUE TO FLASH ON THE INSTRUMENT PANEL AND THE RADIO REMAINS TURNED ON (UNLESS I MANUALLY TURN IT OFF) EVEN AFTER THE CAR HAS BEEN TURNED OFF AND THE KEY HAS BEEN REMOVED FROM THE IGNITION. THIS CAUSED A DEAD BATTERY AFTER 4 DAYS OF FLASHING (RADIO WAS OFF). IT HAS ALSO CAUSED AN ERROR BETWEEN THE COMMUNICATION PATHS FROM MY TRANSMISSION CONTROL MODULE (TCM) AND MY ENGINE'S ECU AND INSTRUMENT PANEL AS EVIDENCED BY THE ERROR CODES PRODUCED. THE LAST ISSUE THAT HAS BEEN CAUSED BY THE ABS FAILURE IS THAT THE CAR CONTINUES TO RUN FOR SEVERAL SECONDS AFTER THE IGNITION HAS BEEN TURNED OFF AND THE KEY HAS BEEN REMOVED. IT WILL THEN SPUTTER OUT AND TURN OFF. FROM MY RESEARCH, THIS APPEARS TO BE A COMMON PROBLEM ON THESE CARS: HTTP://WWW.PASSATWORLD.COM/FORUMS/SHOWTHREAD.PHP?T=173334 *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.

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.
