1999 Audi Quattro

1999 AUDI A4 QUATTRO ABS LIGHT /BRAKE LIGHT. ABS LIGHT PROBLEM. THE PROBLEM STARTED WHEN SLOWING TO A STOP (NORMALLY) THE ABS UNIT WOULD JUMP IN AND ACT AS IF I WAS SKIDDING, WHEN OBVIOUSLY I WASN'T. AT THIS POINT ABS LIGHT WAS NOT ON. AFTER ABOUT A MONTH OF THIS FUNNY ABS ACTUATION MAYBE ONCE A WEEK, THE ABS LIGHT DECIDED TO COME ON AND STAY ON ALONG WITH A BLINKING BRAKE LIGHT AND BEEPING. AT TIMES IT WOULD SHUT OFF, BUT WOULD COME BACK ON AT SOME POINT DURING THAT DAY. I HAD THE SPEED SENSOR REPLACED, BUT TO NO AVAIL. NOW IT ALWAYS BLINKS WHEN RUNNING.DIAGNOSTICS SHOW NO PROBLEM. THERE SEEMS TO BE TOO MANY POSTINGS ABOUT THIS SAME ISSUE WHICH SOUNDS LIKE THE ABS CONTROL MODULE NEEDS TO BE REPLACED. DEALER SAID THEY COULD REPAIR IT AT A COST OF APPROX. $1600.00 . DEALER SAID EVEN THOUGH IT IS A COMMON PROBLEM IT WAS NOT COVERED UNDER RECALL. I HAVE NOT HAD THE WORK DONE YET BECAUSE OF THE COST. *NM

THE ABS BRAKE MODULE ON MY CAR GAVE OUT AND HAS LED TO VERY POOR BRAKING, ALMOST CAUSING 2 ACCIDENTS. I FOUND OUT THAT THIS IS A RECURRENT PROBLEM IN THE 1999 AUDI A4 (I FOUND THIS AT HTTP://AUTOS.MSN.COM/RESEARCH/VIP/RELIABILITY.ASPX?YEAR=1999&MAKE=AUDI&MODEL=A4: "AN OCCASIONAL PROBLEM ON THIS VEHICLE IS FAILURE OF THE ANTI-LOCK BRAKE (ABS) CONTROL MODULE. FAILURE OF THE ABS CONTROL MODULE MAY RESULT IN ABS WARNING INDICATOR ILLUMINATION. THE COST TO REPLACE THE ABS CONTROL MODULE IS ESTIMATED AT $2,228.00)"). *JB

THE ABS LIGHT COMES ON INTERMITENTLY. IT WILL COME ON, BEEP 3 TIMES, AND THEN FLASH FOR A WHILE. IT WILL STAY ON FOR SOME TIME, AND THEN TURN OFF. THIS PROBLEM HAS NO RELATIONSHIP TO WHEN I'M MOVING OR STOPPED. THE ABS LIGHT MAY TURN ON OR OFF AN AN TIME. AND WHEN I TRY TO CONNECT WITH THE HANDHELD DIAGNOSITC SYSTEM, IT FAILS TO CONNECT AND GIVE AN ERROR CODE. OCCASIONALLY WE HAVE GOTTEN SOME OBSURE ERROR MESSAGES ABOUT A DASH CONNECTOR FAILURE, BUT USUSLY WE CANNOT CONNECT WITH THE HANDHELD UNIT, OR PC. I'VE BEEN TOLD THAT THE BRAKE SHOULD STILL WORK, BUT THAT THE BACK BREAKS MAY LOCKUP.*AK
