FAILURE OF IGNITION COILS ON AUDI A4 1.8 TURBO ENGINE. *TR

1. NORMAL DRIVING IN SUBURBAN CONDITIONS - APPROXIMATE SPEED BETWEEN 20MI/HR - 30MI/HR 2. SUDDEN LOSS OF ENGINE POWER AND SUBSEQUENTLY ENGINE RUNS ROUGH 3. IGNITION COILS REPLACED BY AUDI DEALER. *TR

TL*THE CONTACT OWNS A 2003 AUDI A4. THE CONTACT NOTICED WATER IN THE FOOT WELLS ON BOTH THE DRIVER'S AND PASSENGER SIDE OF THE VEHICLE. WHEN HE STARTED THE VEHICLE, THE ELECTRICAL SYSTEM WENT HAYWIRE. THE DEALER STATED THAT THE ELECTRONIC CONTROL MODULE WAS FLOODED DUE TO CLOGGING OF THE INTAKE PLENUM DRAIN GROMMET. THE CONTACT WAS ADVISED TO HAVE IT CLEANED IN ORDER TO PREVENT FUTURE FAILURES. THE MANUFACTURER STATED THAT THERE WAS NO RECALL FOR HIS YEAR, MAKE, AND MODEL VEHICLE. THE CURRENT MILEAGE WAS APPROXIMATELY 37,000 AND FAILURE MILEAGE WAS 31,342. UPDATED 8/7/09 *CN UPDATED 08/11/09.*JB

ON THREE SEPARATE OCCASIONS MY 2003 A4 (1.8T) STARTED SHAKING VIOLENTLY AS I ACCELERATED FROM A COMPLETE STOP. EVERY TIME IT HAPPENED THE CHECK ENGINE LIGHT CAME ON, THE CAR LOST MOST ALL OF ITS POWER AND WAS DIFFICULT TO STEER, AND WOULDN'T GET ABOVE 15 MPH. AND EVERY TIME IT HAPPENED I WAS STRANDED IN THE MIDDLE OF TRAFFIC, HAVING TO COAX THE CAR OVER TO THE SIDE OF THE ROAD AND OUT OF HARM'S WAY. THE CAR WAS TOWED EACH TIME TO THE DEALERSHIP WHERE I WAS TOLD THAT AN IGNITION COIL (OR TWO) HAD BLOWN. ALL 4 COIL PACKS HAD TO BE REPLACED WITHIN A YEAR AT A COST OF OVER $900. AUDI KNOWS THEY PRODUCED CARS WITH FAULTY IGNITION COILS IN A4 CARS EQUIPPED WITH 1.8 LITER ENGINES IN THE 2001, 2002, AND EARLY PRODUCTION 2003 MODEL YEARS. IN FEBRUARY 2003 THEY ANNOUNCED THAT THEY WOULD REPLACE THESE COILS FREE OF CHARGE TO THE VEHICLE OWNERS. ALTHOUGH MY CAR IS AN EARLY PRODUCTION 2003 MODEL, AUDI USA TOLD ME THAT MY CAR WAS PRODUCED VERY SOON AFTER THE RANGE OF CARS COVERED IN THE REPLACEMENT. MEANING THAT I WAS RESPONSIBLE FOR THE COST OF ALL REPAIRS. I DO NOT BELIEVE AUDI IS CERTAIN THEIR REPLACEMENT ACTION COVERED ALL DEFECTIVE COILS, ESPECIALLY AS MY CAR WAS PRODUCED IN THE SAME TIME FRAME AS THOSE THAT WERE PART OF THE REPLACEMENT. FAULTY IGNITION COILS EXIST IN A FAR GREATER NUMBER OF CARS THAN WHAT AUDI RECOGNIZES AND COVERS IN THEIR 2003 REPLACEMENT ACTION. *TR

1.THE EVENTS LEADING UP TO THE FAILURE: AUDI A4S HAVE AN INTAKE PLENUM DRAIN GROMMET LOCATED NEAR THE BATTERY; THIS FUNNEL IS KNOWN TO BECOME CLOG DUE TO DEBRIS AND GRIME. THE DRAIN GROMMET ON MY VEHICLE BECAME CLOGGED SOME TIME AGO AND I DID NOT BECOME AWARE OF THIS PROBLEM UNTIL THE FUNNEL STOPPED WORKING AND ALLOWED WATER TO DRAIN INSIDE MY CAR. THIS CAUSED MY COMFORT MODULE TO FAIL - MY POWER WINDOWS, POWER LOCKS, INTERIOR LIGHTS, KEYLESS REMOTE ENTRY, ALARM, TRUNK, BATTERY AND GAS TANK LID CEASED TO FUNCTION. 2.THE FAILURE, HOW OFTEN IT OCCURS, ITS CONSEQUENCES; AND, AUDI OF AMERICA KNOWS ABOUT THIS PROBLEM. THIS PROBLEM IS PRETTY COMMON IN THE 2003 AUDI A4'S. IF YOU DO A SEARCH ABOUT IT ONLINE, MANY CONSUMERS ARE AFFECTED BY THIS CLOGGED DRAIN GROMMET. UPON DOING MORE RESEARCH, I WAS SHOCKED TO LEARN THAT THE 2002 AUDI A4 MODELS HAD EXACTLY THE SAME PROBLEM, BUT HAD ITS VEHICLES RECALLED. 3.WHAT WAS DONE TO CORRECT THE FAILURE; I.E, PARTS REPAIRED OR REPLACED (AND IF OLD PART IS AVAILABLE) I BROUGHT MY 2003 AUDI A4 TO THE DEALERSHIP (AUDI OF HAWAII) TO CORRECT THE PROBLEM, WHICH COST ME $1400. THE TECHNICIANS REPLACED THE PLENUM GROMMET DRAIN, COMFORT MODULE, BATTERY, AND HAD TO CLEAN THE BOTTOM INTERIOR OF MY CAR WHICH WAS SATURATED WITH WATER, MOLD, AND MILDEW. I ALSO WROTE A LETTER TO AUDI OF AMERICA AND AUDI OF HAWAII TO ADDRESS THIS PROBLEM TO OTHER 2003 AUDI A4 OWNERS SINCE IT WAS ADDRESSED FOR THE 2002 AUDI A4 VEHICLES. THEIR REPLY WAS THAT SINCE IT HAD NOT BEEN 'FEDERALLY MANDATED' THEY WILL NOT HAVE A RECALL FOR THE 2003 AUDI A4. *TR

IGNITION COILS HAVE GONE OUT 2 TIMES ALREADY. FIRST INCIDENT HAPPENED ON MAY 29,2007, SECOND HAPPENED IN AUGUST OF 2007. *TR

AUDI A4 6-CYL 3.0L AVANT 2003 MODEL YEAR. COIL PACK #2 FAILED ON SEP 28TH 2007. AUDI HAS HAD A RECALL FOR THE 2003 A4 4-CYL 1.8L ENGINES BUT NOT FOR THE 3.0L ENGINES. THE VEHICLE ONLY HAS 37K MILES ON THE ODOMETER. IT'S LIKELY THAT THERE WILL BE MORE CP FAILURES, UNTIL I HAVE ALL OF THEM REPLACED. THERE SHOULD HAVE BEEN A RECALL FOR THE 3.0L ENGINE AS WELL. *TR

WHILE DRIVING, ENGINE LOST POWER, WAS ABLE TO GET THE VEHICLE INTO A PARKING LOT AND HAD IT TOWED TO MECHANIC. IGNITION COIL IN CYLINDER #2 FAILED AND HAD TO BE REPLACED.

THE CAR (AN AUDI A4) STARTED SHAKING AND COULD NOT BE DRIVEN OVER 40 MILES PER HOUR. IT HAD TO BE PULLED OVER TO THE SIDE OF THE ROAD AND BE TOWED TO A DEALER TO REPLACE 2 SPARK PLUG IGNITION COILS. 4 SPARK PLUG IGNITION COILS HAVE FAILED DURING THE PAST YEAR. THE MOST RECENT OCCURRENCE IS LISTED BELOW. *JB

ON OCTOBER 11TH MY FUEL FILTER AND PUMP WERE REPLACED AND A ROAD TEST WAS COMPLETED...ON NOVEMBER 14TH (5 WEEKS LATER) MY A4 BEGAN TO SHAKE AND THE MIL CAME ON. I PULLED VEHICLE TO SIDE OF THE ROAD AND HAD IT TOWED TO DEALER. DEALER INFORMED ME THAT INGNITION COIL FAILED AND HAD STARTED TO AFFECT THE SPARK PLUGS AND WAS ONLY RUNNING ON 3 CYLINDERS AS A RESULT. THEY REPLACED THE COIL AND COMPLETED A ROAD TEST - HOWEVER THEY HAD COMPLETED A ROAD TEST 5 WEEKS AGO TOO - SO I AM FEELING LEST CONFIDENT WHEN I DRIVE...FEARFUL OF DRIVING IN LESS FAMILIAR LOCATIONS OR IN ANY LANE EXCEPT THE SLOW LANE IN CASE I NEED TO PULL OVER. *NM

IN 1/04, DURING NORMAL DRIVING CONDITIONS ONE EVENING, MY '03 1.8T A4 BEGAN SHAKING VIOLENTLY AS I BEGAN ACCELERATED FROM A STOP SIGN. THE CHECK ENGINE LIGHT CAME ON AND I LOST A SIGNIFICANT AMOUNT OF POWER AND COULDN'T ACCELERATE WELL. THE DEALER STATED THAT I BLEW AN IGNITION COIL. NOT 2 MONTHS LATER, IN EARLY 3/04, THE SAME EXACT SITUATION OCCURED AND I HAD TO HAVE ANOTHER IGNITION COIL REPLACED. I HAVE LEARNED THAT THE MFR HAD A PRODUCT RECALL FOR THIS EXACT PROBLEM, HOWEVER MY VEHICLE'S COMPONENTS ARE NOT COVERED BY THOSE UNDER RECALL. I WAS TOLD I HAVE THE "NEWER" VERSIONS OF THE IGITION COILS ALREADY IN MY CAR. WHILE THEY MIGHT BE NEWER, THEY SURE HAVEN'T SOLVED THE UNDERLYING PROBLEM! TWO BLOWN IGITION COILS IN LESS THAN 2 MONTHS AND I CAN'T GET THE MFR TO REPLACE THE OTHER 2 COILS THAT I'M CERTAIN WILL GO OUT AT SOME POINT SOON TOO.
