1998 Audi Quattro

I PURCHASED MY 1998 AUDI A4 1.8T AWD VEHICLE IN APRIL OF 2004 WITH 91,000. THE BRAKES AND ROTORS WERE REPLACED IN MAY OF 2004. THE CAR HAS HAD NO PROBLEMS WITH THE BRAKES UNTIL JULY 11, 2005. ON THIS DATE THE ABS LIGHT CAME ON ONCE. I CHECKED THE ABS MODULE FOR DTC CODES AND IT DISPLAYED A CODE TO DO WITH AN INTERMITANT CONNECTION BETWEEN THE INSTRUMENT CLUSTER AND THE ABS CONTROL MODULE. ABS WILL NOT FUNCTION WHEN THE LIGHT IS ON. WITH THE MODULE NO LONGER FUNCTIONING, THE ABS PUMP MAY MALFUNCTION CAUSING OVERHEATING AND/OR LOCKING UP OF BRAKES ON INDIVIDUAL WHEELS. THIS MAY CAUSE THE VEHICLE TO BE UNSAFE AS THE REAR WHEELS MAY LOCK UP MORE EASILY UNDER HARD BRAKING AND CAUSE THE VEHICLE TO SPIN WHILE BRAKING AROUND A CORNER. THE BRAKING SYSTEM ON MY VEHICLE HAS BEEN SERVICED AT REGULAR MAINTENANCE INTERVALS AT THE AUDI DEALERSHIP BY THE PREVIOUS OWNER AND BY MYSELF FOR THE YEAR AND THREE MONTHS THAT I HAVE OWNED IT. ALL OTHER RECALLS (LOWER CONTROL ARM INSPECTION AND REPLACEMENT OF TIE ROD ENDS) ON THE VEHICLE HAVE BEEN ATTENDED TO BY THE PREVIOUS OWNER AND BY MYSELF SINCE I HAVE OWNED IT.
