“ABS MODULE APPEARS TO BE FAULTY. ABS AND BRAKE LIGHT REMAIN ON/FLASHING. LOSS OF ABS COULD CAUSE COLLISION, DEALER WANTS $1000+ FOR THE PART AND DOES NOT GUARANTEE IT WILL FIX THE PROBLEM. *TR”
“THE ABS LIGHT COMES ON,FOLLOWED BY THE BRAKE LIGHT BLINKING THE ENGINE OIL LIGHT COMES ON AND THE TACHOMETER GOES TO 0 AND STOPS WORKING EVEN THOUGH I AM ACCELERATING. THERE ARE MANY OTHERS WITH THIS SAME ISSUE IT CAN BE RESEARCHED ON HTTP://TECH.BENTLEYPUBLISHERS.COM/THREAD.JSPA?THREADID=2447&TSTART=0. *TR”
“THE ABS MODULE IN MY 1998 VOLKSWAGEN PASSAT 1.8T HAS GONE BAD. THIS FAULT CAME WITHOUT NOTICE OF ANY SYMPTOMS AND COMPLETELY UNPROVOKED. THE WARNING LAMP AND TONE APPEAR EVERY TIME I START THE VEHICLE. THIS IS A KNOWN ISSUE WITH MANY INDEPENDENT VOLKSWAGEN MECHANICS AND MANY PASSAT OWNERS. *TR”
“ABS BRAKES CEASED TO FUNCTION AFTER APPROX 60K MILES. BECAUSE OF THE EXPENSE TO FIX (DEALER QUOTED $2400, INDIE MECHS ABOUT $1400), THEY REMAIN NON-FUNCTIONAL (MY CAR IS NOW 95K MILES). *TR”
“MY ABS LIGHT INTERMITTENTLY COMES ON FOLLOWED BY THE BRAKE LIGHT FLASHING> UPON RESEARCHING THIS ON SEVERAL VARIOUS FORUMS ON THE NET. THIS APPEARS TO BE A COMMONLY DEFECTIVE PART ON SEVERAL MODEL YEARS FROM 98-01. THE OLDEST POSTING I FOUND WAS DONE IN 2000 AND THE VEHICLE WAS A 99. FROM RESEARCHING THIS IT APPEARS EVEN VW DEALERS ARE UNABLE TO GET CORRECT PROBLEM CODES ON THIS ISSUE. I SAW POSTINGS FROM MANY OWNERS STATING THEY WERE TOLD EVERYTHING FROM ABS MODULES NEEDING REPLACED TO INSTRUMENT CLUSTERS TO WIRING ISSUES. IT APPEARS NO ONE IS ABSOLUTELY SURE WHAT THE ISSUE IS AS SOME OWNERS AFTER THE DEALER RECOMMEND REPLACEMENTS DID NOT FIX THE ISSUE. IN THE SHORT TIME I LOOKED INTO THIS I FEEL THAT VW SHOULD BE WELL AWARE OF THIS ISSUE AND HAVE TAKEN STEPS TO RESOLVE IT. I SAW LITERALLY YEARS WORTH OF POSTINGS A ON THIS ISSUE ON BENTLEY PUBLISHERS WEBSITE. I CAN ONLY IMAGINE HOW MANY THOUSANDS OF PEOPLE HAVE HAD TO PAY FOR THINGS THAT DID NOT DO ANY RESEARCH ON IT. *TR”
“MANY AUDI AND VW MODELS MANUFACTURED STARTING IN THE LATER '90S AND EALRY '00S, USE THE BOSCH 5.3 ABS CONTROLLER, WHICH IS PRONE TO CATASTROPHIC FAILURE, OSTENSIBLY DUE TO DEFECTIVE DESIGN. THIS MODULE CONTROLS MULTIPLE BRAKE-RELATED FUNCTIONS INCLUDING THE ABS WHICH IS IMPORTANT FOR WINTER DRIVING, BUT THE MOST CRITICAL FUNCTION OF THIS MODULE IS PROBABLY THE ELECTRONIC BRAKE FORCE DISTRIBUTION, OR EBD. THESE VEHICLES ARE DESIGNED SUCH THAT IF THE EBD IS INOPERATIVE, THE PROPORTION OF HYDRAULIC FORCE APPLIED TO THE REAR BRAKES DURING EMERGENCY BRAKING IS AS GREAT AS IT IS DURING MODERATE BRAKING EFFORT WHEN THERE IS MINIMAL TRANSFER OF VEHICLE WEIGHT TO THE FRONT WHEELS. THE EBD IS SUPPOSED TO ADJUST THE FRONT/REAR BRAKING DISTRIBUTION DYNAMICALLY ACCORDING TO THE MEASURE OF THE DECELERATION, SO THAT THE REAR WHEELS WILL NOT LOCK UP DURING EMERGENCY BRAKING. IF THIS MODULE SHOULD FAIL DURING EMERGENCY BRAKING ON DRY PAVEMENT, THE REAR WHEELS COULD LOCK UP AND CAUSE AN ACCIDENT WHICH COULD EASILY INCLUDE FATALITIES. THIS IS AN EXPENSIVE REPAIR FOR OWNERS, COSTING ROUGHLY $2000, AND MANY OWNERS HAVE PROBABLY PUT OFF THE REPAIR INDEFINITELY. EVIDENCE WHICH CAN BE…”
