1998 AUDI A6 Service Brakes, Hydraulic Problems

DEAR DOT, I'VE A 1998 AUDI A6 QUATTRO. MY ABS SYSTEM SHOWS WARNING YELLOW ABS LIGHT AND RED FLASHING BRAKE LIGHT AT ALL TIME. I'VE TAKEN MY TWO SHOPS AND THEY BOTH INDICATED THAT THE ABS UNIT IS DEFECTIVE AND NEEDS REPLACEMENT. THEY TESTED ALL 4 WHEEL SENSORS ON THE CAR AND ALSO MAPPED OUT THE ELECTRICAL SYSTEM. THE CONCLUSION WAS A DEFECTIVE ABS UNIT. I'VE DONE SOME RESEARCH AND OTHER AUDI OWNER FROM 1998 - 2001 ALSO HAVE THE SAME ISSUES. IF THIS SYSTEM IS KNOWN TO BE DEFECTIVE, IT SHOULD BE RECALLED IN ALL FAIRNESS. I AM PRETTY HAPPY WITH THIS CAR, BUT THE ABS IS AN UNCOMFORTABLE EXPERIENCE. IT COST ABOUT $2000 TO REPLACE THE ABS UNIT AND AUDI DOES NOT WANT TO ADMIT THE PROBLEM.

THE ABS BRAKING LIGHT APPEARED ON THE DASHBOARD AND REMAINED ON. DRIVER NOTICED THAT WHILE APPLYING THE BRAKES THE PEDAL WENT TO FLOOR, SLOWING DOWN AND THEN STOPPING. DRIVER TOOK VEHICLE TO THE DEALER, AND THE MECHANIC PLACED THE VEHICLE ON A DIAGNOSTIC MACHINE, AND DETERMINED THAT THE ABS CONTROL UNIT MODULE NEEDED TO BE REPLACED. *AK

I OWN A 1998 AUDI A6. THIS VEHICLE HAS BEEN DRIVEN APPROX 75 000 MILES. SEVERAL MONTHS AGO THE ABS CONTROL UNIT (BRAKES) FAILED. I WAS QUOTED A PRICE OF $1085 BY THE DEALERSHIP WHERE I PURCHASED THE VEHICLE. THERE ARE NO USED PARTS AVAILABLE. WHEN I MADE AN APPOITMENT TO HAVE THE UNIT REPLACED I WAS INFORMED THAT AUDI NO LONGER MANUFACTURES THE ORIGIONAL REPLACEMENT PART AT A COST OF $1085. RATHER, AUDI HAS REMANUFACTURED THE REPLACEMENT PART AND THE NEW COST IS APPROX $2000.00. I VERIFIED THE COST OF THE REMANUFACTURED REPLACEMENT PART BY CALLING A FEW DEALERSHIPS. MY COMPLAINT IS THAT I BELIEVE THAT AUDI RECOGNIZED THAT THE ORIGINAL PART WAS DEFECTIVE AND THAT ONCE THE ABS CONTROL UNIT FAILED IT MADE ABS BRAKING INOPERABLE AND THEREFORE UNSAFE. RATHER THAN RECALL THE 1998 A6 TO REPLACE THE DEFECTIVE ABS CONTROL UNIT, THEY ALLOWED CONSUMERS TO EITHER DRIVE WITH AN UNSAFE CONTROL UNIT THAT COULD FAIL AT ANY TIME OT PAY ALMOST $2000 TO REPLACE THE DEFECTIVE PART.*AK
