1999 Audi A6 service brakes, hydraulic problems

“MY 1999 AUDI A6 2.8 HAS ABS CONTROL MODULE FAILURE. THIS APPEARS TO BE A COMMON PROBLEM AMONG 1996 TO 2001 AUDI'S AND VW'S LACK OF ANTI-LOCK BRAKING SYSTEM CONTROL MAKES MY VEHICLE UNSAFE. AUDI IS NOT WILLING TO CORRECT THIS PROBLEM. THIS PROBLEM AFFECTS A LARGE NUMBER OF VEHICLES.”

“DRIVING HOME TONIGHT MY CAR ALL OF A SUDDEN STARTED ACCELERATING (I DRIVE AN AUDI A6 1999). USING THE BRAKES I WAS ABLE TO SLOW IT DOWN ENOUGH TO GET OFF THE FREEWAY THOUGH MY BRAKES SEEMED TO BE FIGHTING AGAINST THE CAR. I ROLLED THROUGH TWO STOP SIGNS AS MY CAR WOULD NOT STOP AND LUCKILY AVOIDING THE OTHER CARS WAITING THERE I WAS ABLE TO PUT MY CAR IN PARK AND TURN OFF THE ENGINE. I WAITED TEN MINUTES OR SO AND TRIED STARTING MY CAR. THE ENGINE REVVED TO 4 TO 5000 RPMS SO, I QUICKLY SHUT IT OFF AGAIN. I WAITED AGAIN, TRIED IT ONCE MORE AND THE CAR STARTED FINE. I DROVE HOME, CALLED THE DEALERSHIP AND WAS TOLD I COULD BE SEEN ON 02/14/11. FOUR DAYS FROM NOW. THIS IS THE SECOND TIME THIS HAS HAPPENED. *TR”

“I HAVE A 1999 AUDI A6 QUATTRO -- ABS UNIT LIGHT FLASHES, DIAGNOSED AS A DEFECTIVE CONTROL UNIT. THIS APPEARS TO BE A VERY COMMON PROBLEM WITH AUDI AND VW AND A SERIOUS SAFETY ISSUE. *TR”

“ALL OF A SUDDEN MY ABS LIGHT CAME ON IN MY 1999 AUDI A6, AND THE BRAKE LIGHT STARTED FLASHING. I HAD A FULL LOSS OF MY ABS BRAKES ON ICY WINTER ROADS. I EVENTUALLY SLID OFF THE ROAD AND HIT A FENCE. THE ABS CONTROL MODULE ON MY CAR HAD FAILED, AND I'VE READ POSTS OF SEVERAL HUNDREDS OTHER HAVING THE SAME PROBLEM. IN MY CAR IT IS A CONSTANT ERROR, AND NO-ONE BUT AUDI CAN FIX THE PROBLEM. I ALSO CONTACTED AUDI, WHICH CLAIMS THAT THE ABS SYSTEM DISABLING IS NOT A SAFETY CONCERN. WHEN THERE'S A CHANCE THAT YOUR ABS (SOMETHING YOU'VE RELIED ON FOR YEARS) SUDDENLY SHUTS DOWN BECAUSE OF A WAY TOO COMMON ERROR, IT IS A MAJOR SAFETY CONCERN. I WAS LUCKY I ONLY GOT SOME DENTS TO MY CAR, BUT IF AUDI HAD RECALLED THESE I WOULDN'T HAVE HAD TO GET REPAIRS DONE TO MY CAR. UNFORTUNATELY SOMEONE WILL PROBABLY HAVE TO DIE BEFORE THIS SAFETY CONCERN IS TAKEN SERIOUSLY AND AUDI WILL DO A RECALL. *TR”
