“2001 AUDI A4 WITH ABOUT 105K MILES ON. ABS SENSOR IS FAULTY AND THIS PROBLEM IS VERY WIDESPREAD AMONGST AUDI A4S BUILT AROUND THIS TIME. IT IS A $1500 - $2000 REPAIR FOR A PART THAT REALLY DOESN'T SEEM TO GO BAD WITH THIS FREQUENCY IN OTHER CARS. FOR AN EXAMPLE OF THE SCORE, SEE THIS SITE. THIS IS JUST ONE OF MANY SITES WITH SIMILAR COMPLAINTS AROUND THIS ISSUE: HTTP://AUDI-VW-ABS-RECALL.BLOGSPOT.COM/2005/07/AUDI-AND-VW-PLEASE-RECALL-CARS-BETWEEN.HTML. *TR”

“ABS CONTROL MODULE FAILED. MODULES ARE DEFECTIVE AND AUDI SHOULD RECALL THEM. ONLINE RESEARCH SHOWS THOUSANDS OF AUDI/VW CAR OWNERS HAVE EXPERIENCED THIS SAME PROBLEM. COST TO REPLACE MODULE IS $1500-2000 DOLLARS. VW HAS ISSUED RECALL OF THIS ABS MODULE, BUT AUDI HAS NOT (EVEN THOUGH SAME EXACT PART). NHTSA NEEDS TO PUT PRESSURE ON AUDI TO RECALL THIS COMPONENT, THEY ARE DEFECTIVE, UNSAFE, AND COULD LEAD TO ACCIDENTS. *TR”

“TL* THE CONTACT OWNS A 2001 AUDI A4. HE STATED THAT THE ANTILOCK BREAKS SENSOR ILLUMINATES CONSTANTLY. HE HAD THE GARAGE REPLACED THE BREAK SENSOR TWICE.

THE FAILURE MILEAGE WAS 90,000 AND THE CURRENT MILEAGE WAS 102,034. HE HAS NOT CONTACTED THE DEALER OR MANUFACTURER.”

“1. ONE DAY SUDDENLY MY AUDI 2001 A4 STARTS TO SHOW ABS AND BRAKE LIGHT TO BE FAILING. 2. THE FAILURE WHEN DIAGNOSED SEEMS TO BE A PROBLEM WITH AUDI'S ABS CONTROL UNIT, AND THAT NEEDS TO BE REPAIRED. 3. I HAVE NOT REPAIRED IT YET, BECAUSE DEALERS QUOTED A HUGE PRICE OF MORE THAN 1500$ TO FIX THE ABS CONTROL UNIT. *TR”

“WHILE DRIVING IN SUBURBAN TRAFFIC, I NOTICED THE BRAKE PEDAL FULLY DRESS WHEN I ATTEMPTED TO SLOW FROM ABOUT 30 MPH. UPON SUBSEQUENT STOPS, THERE WAS A METAL ON METAL SOUND. UPON INSPECTION, THE RIGHT FRONT OUTER PAD HAD COMPLETELY DETACHED FROM BACKING PLATE. THE CAR WAS INSPECTED BY AUDI ONLY 3K MILES EARLIER AND THERE WAS NO INDICATION OF BRAKE PAD WEAR. NEITHER THE DEALER NOR AUDI WOULD ACKNOWLEDGE OR ACCEPT RESPONSIBILITY. *TR”
