I HAVE A 2005.5 AUDI A4 2.0T QUATTRO WHICH HAS ENCOUNTERED A FAILURE OF THE ABS/ESP ELECTRICAL MODULE. THE RESULT IS FAILURE OF THE ESP SYSTEM AND THE ABS SYSTEM. THIS IS THE RESULT OF A FAULTY ELECTRICAL MODULE WHICH MANY FORUMS DESCRIBE AS A FREQUENT OCCURRENCE AND AS A RESULT A REDESIGN BY THE MANUFACTURER. THE AUDI PART IS ~$1900. BASED ON THE EXPERIENCE OF MANY OWNERS AND THE SAFETY IMPLICATIONS I WOULD EXPECT THE MANUFACTURER TO COVER THE COSTS OF CORRECTING THE DEFECT.

AS I WAS DRIVING THE GAS PEDAL WENT TO THE FLOOR FULL THROTTLE. I ALMOST HAD AN ACCIDENT. I FINAL GOT THE CAR OVER TO THE ROAD AT A STOP BY PUTTING THE CAR IN NEUTRAL. THE ENGINE REVVED UP AS HIGH AS IT COULD GO. SO I CUT THE CAR OFF THEN CUT IT BACK ON AND IT CONTINUED TO HAVE THE SAME PROBLEM. IT TOOK 3 TIMES OF CUTTING THE CAR OFF AND WAITING A FEW MINUTES BEFORE THE CAR RETURNED TO NORMAL.

TL* THE CONTACT OWNS A 2005 AUDI A4. WHILE DRIVING APPROXIMATELY 35 MPH, THE DRIVER DEPRESSED THE ACCELERATOR PEDAL AND NOTICED THAT THE ACCELERATOR PEDAL HAD BECOME STUCK. THE VEHICLE SUDDENLY ACCELERATED TO 100 MPH ERRONEOUSLY. THE CONTACT CONTINUED DEPRESSING THE BRAKE PEDAL AND WAS ABLE TO STOP THE VEHICLE. THE VEHICLE WAS NOT TAKEN TO THE DEALER FOR DIAGNOSTIC TESTING OR POSSIBLE REPAIRS. THE DRIVER INSPECTED THE VEHICLE AND NOTICED THAT THE FLOOR MAT RETENTION SYSTEM FAILED AND CAUSED THE FLOOR MAT TO BECOME LODGED UNDER THE ACCELERATOR PEDAL, CAUSING THE FAILURE. THE APPROXIMATE FAILURE MILEAGE WAS 69,224.

I PURCHASED THE VEHICLE ON 02/11/2012 AND THAT VERY EVENING WHEN I HAD THE OPPORTUNITY TO USE THE LIGHTS, MY RIGHT LIGHT BEGAN TO FLICKER AND THEN FAILED COMPLETELY. THIS REALLY UNNERVED ME AS I WAS IN AN AREA WITH NO STREET LIGHTS. AND DIDN'T REALLY KNOW WHAT WAS HAPPENING. I INSTINCTIVELY TURNED THE LIGHTS OFF AND THEN ON AGAIN, AND THIS MADE THEM COME BACK ON. UNFORTUNATELY, THIS HAPPENED NUMEROUS TIMES THAT NIGHT. I FEEL THIS IS A BLATANT SAFETY ISSUE ESPECIALLY AS I HAD FAMILY MEMBERS IN MY CAR AND THEIR WELL BEING WAS COMPROMISED. I HAVE RESEARCHED THIS PROBLEM VIA THE INTERNET AND IT APPEARS TO BE RAMPANT ON AUDI'S AND THE DEALERSHIPS DON'T EITHER KNOW WHAT TO DO OR DON'T WANT TO DO IT AS FOR THE EXPENSE OF THE PARTS.I SPOKE WITH NO LESS THAN 8 AUDI DEALERSHIPS AROUND THE PA NORTHEAST AND NO ONE COULD POSITIVELY SAY WHAT WOULD BE THE PROBLEM. I AM HAVING THE BULB REPLACED AT MY COST BECAUSE I BOUGHT THE CAR USED AND HAVE NO WARRANTY. NOW I KNOW WHY I WAS ABLE TO PURCHASE IT AT A GOOD COST. LAST OWNER WAS PROBABLY CRAZY OVER THIS. BY ALL ACCOUNTS, EVEN REPLACING THE BULB MIGHT NOT WORK. THERE ARE NO LESS THAN 4 TSB'S OUT ON THIS PROBLEM. WHY AUDI GETS AWAY WITH THIS IS A TRAVESTY AND THIS SHOULD BE REMEDIED AS SOON AS POSSIBLE BEFORE SOMEONE GETS KILLED. *TR

UNINTENDED ACCELERATION: VEHICLE CONTINUED TO ACCELERATE AFTER ENTERING HIGHWAY. DRIVER PUT THE CAR IN NEUTRAL (MANUAL TRANSMISSION). TACHOMETER CONTINUED TO INCREASE UNTIL IT RED-LINED. DRIVER PULLED OFF THE HIGHWAY AND TURNED THE ENGINE OFF. THE THROTTLE RELEASED WITH A POPPING NOISE. DRIVER OBSERVED THE THROTTLE AND THE MAT DID NOT APPEAR TO BE PUSHING ON THE THROTTLE BUT THE MAT WAS NOT SECURED IN PLACE. TOOK THE CAR TO THE DEALER (WHERE IT WAS BOUGHT AND SERVICED REGULARLY). THEY RAN DIAGNOSTIC SCAN, NO FAULTS IN SYSTEM. OWNERS WROTE AND CALLED AUDI CUSTOMER CARE AND WERE INFORMED CAR IS WORKING AS DESIGNED. WEATHER WAS HOT AND DRY (JULY).

2005.5 (MIDYEAR) AUDI A4 2.0T WHILE DRIVING ON THE HIGHWAY, THE CAR BEGAN TO ACCELERATE OUT OF CONTROL FOR APPROXIMATELY 15-25 SECONDS DESPITE THE FACT THAT THE ACCELERATOR WAS NOT BEING DEPRESSED. THIS OCCURRED EVEN THOUGH NO PRESSURE WAS BEING APPLIED TO THE GAS PEDAL. THE CAR QUICKLY PICKED UP SPEED, REACHING SPEEDS OF 90+ MPH ON A CROWDED URBAN HIGHWAY DURING RUSH HOUR. A COLLISION WAS BARELY AVOIDED. THERE WAS NO MECHANICAL OBSTRUCTION TO THE GAS PEDAL (I.E THERE WAS NO MAT OR DEBRIS IN THE WAY). FURTHERMORE, THERE WAS LIMITED BRAKE FUNCTION AT THIS TIME. AFTER 15-25 SECONDS THE CAR STOPPED ACCELERATING ON ITS OWN. THE ISSUES: 1. UNCONTROLLED ACCELERATION TO REDLINE WITH NO CONTROL OVER THE ACCELERATOR 2. BRAKING FUNCTION FAILED TO OVERRIDE THE ACCELERATOR FUNCTION (AS EXPLAINED BY MY DEALER. IF YOU BRAKE WHILE ACCELERATIONS, THE BRAKES WIN, WHICH DID NOT OCCUR IN THIS CASE.) I HAD THE VEHICLE INSPECTED BY MU AUDI SERVICE DEPARTMENT WHO SAID THAT NOTHING WAS WRONG WITH THE CAR. *TR

I BELIEVE THIS MAY BE A REPEAT COMPLAINT, BUT MS. DEMETER SAYS IT IS NOT ON FILE. 2005 AUDI A4 CABRIOLET, 6 CYLINDER (NORMALLY ASPIRATED). SUDDEN PERSISTENT ACCELERATION. I WAS RAPIDLY ACCELERATING FROM ABOUT 25 MPH GOING UP A HILL TRYING TO MAKE A GREEN LIGHT ABOUT .2 MILE AWAY. WHEN I APPROACHED THE INTERSECTION, I RELEASED THE PEDAL BUT THE CAR KEPT ACCELERATING. FIRM BRAKE PRESSURE SLOWED THE CAR, BUT IT REACCELERATED UNTIL I BROUGHT IT TO A STOP. I MADE SURE THE CRUISE CONTROL WAS IN THE "OFF" POSITION, EVEN THOUGH I HAD NOT USED IT. I DROVE ABOUT 2 MILES TO THE NEXT MAJOR INTERSECTION, WHERE I STOPPED FOR ALIGHT. WHILE I WAS SITTING THERE WITH MY FOOT ON THE BRAKE, THE ENGINE BEGAN TO REV. I PUT THE VEHICLE IN NEUTRAL, AND IT REDLINED. I TURNED THE CAR OFF, AND REACHED DOWN TO SEE IF THE FLOOR MAT WAS OUT OF PLACE. I GAVE IT A PULL BUT DID NOT FEEL IT OVER THE GAS PEDAL. I STARTED THE CAR AGAIN, AND SLOWLY ACCELERATED AWAY FORM THE INTERSECTION. THE PROBLEM HAS NOT RECURRED, EVEN WHEN I TRIED TO REPRODUCE IT. *TR

THE ACCELERATOR STUCK AND WOULD NOT DISENGAGE - DESPITE THE FACT THAT I REMOVED BY FOOT FROM THE THROTTLE. I APPLIED THE BRAKES TO GET THE CAR TO STOP AND AFTER A FEW SECONDS THE ACCELERATOR DISENGAGED BUT THEN RE-ENGAGED (BY ITSELF) AND THEN DISENGAGED THREE OR FOUR TIMES IN THREE TO FOUR INTERVALS. *NM

DT: THE CONTACT OWNS A 2005 AUDI A4 2.0 LITER TURBO ENGINE. THE NON LINEAR ACCELERATION, IT WILL BOG AND SURGE WHILE IN TRAFFIC. WHILE PRESSING HARD ON THE GAS, IT WILL SUDDENLY SURGE FORWARD, CAUSING DRIVERS BEHIND HIM TO CONSTANTLY APPLY THE BRAKES. ALSO, THE LOW SPEED POWER STEERING WILL NOT COME ON. IT WAS LIMITED AND VERY HARD TO STEER. THIS PROBLEM WITH THE POWER STEERING STARTED INTERMITTENTLY. THE CONTACT'S VEHICLE WAS INVOLVED IN AN ACCIDENT. BUT BECAUSE OF THE LACK OF POWER STEERING ACCELERATION PREVENTED FROM BEING HIT. THE VEHICLE HAS BEEN AT THE DEALERSHIP FIVE TIMES FOR THE ACCELERATING PROBLEM, AND ONCE FOR THE POWER STEERING PROBLEM. THE DEALERSHIP HAS NOT CORRECTED THE ACCELERATION PROBLEM. THE DEALERSHIP STARTED A DIAGNOSTIC TEST ON THE POWER STEERING. THE CONTACT CONTACTED THE MANUFACTURER MANY TIMES, AND THEY WERE COOPERATIVE. THE REPAIRS ARE BEING DELAYED BECAUSE THE DEALERSHIP FORGOT TO ORDER THE PARTS. THE NUMBERS OF FAILURES WERE 100 TIMES AT LEAST. THE PROBLEMS FIRST BEGAN 10 DAYS AFTER PURCHASE OF THE VEHICLE ON APRIL 4, 2005, AND IT WAS IN FOR SERVICE ON APRIL 14, 2005. THE CONSUMER WAS TOLD THE BOG AND SURGE WAS WITHIN AUDI'S SPECIFICATIONS AND NO CORRECTIVE ACTION WOULD TAKE PLACE. 11/15/05. *JB
