ABS LIGHT COMES ON INTERMITTENTLY AND ABS SYSTEM IS NOT FUNCTIONAL. ABS SYSTEM ALSO USED IN ELECTRONIC DIFFERENTIAL CONTROL. AUDI DEALER DIAGNOSED AS A ABS CONTROL UNIT FAILURE WITH PART COST OF $2600 PLUS LABOR AND WAS REPAIRED BY AUDI DEALER. CONTACTED AUDI CUSTOMER CARE AND THEY DID NOT OFFER ANY ASSISTANCE. THIS IS A VERY REAL SAFETY ISSUE AND BASED ON INTERNET SEARCHES HAS AFFECTED HUNDREDS OF AUDI AND VW VEHICLES. THIS APPEARS TO BE A FAULTY DESIGN OF A CRITICAL SAFETY COMPONENT AND WARRANTS FURTHER INVESTIGATION.

AFTER ONLY 65000 MILES ON MY 1998 AUDI A4 I HAVE BEEN FORCED TO REPLACE MAJOR ABS COMPONENTS BECAUSE OF NUMEROUS FAILURES. THE ABS SYSTEM WORKS INTERMITTENTLY, AND THERE IS NO INDICATION OF WHEN IT WILL FAIL. A BRAKE LIGHT WILL COME ON, THEN GO OFF, INDICATING THERE IS TROUBLE, BUT AT TIMES THE LIGHT WILL BE OFF AND IT IS NOT UNTIL YOU BEGIN TO BRAKE THAT YOU REALIZE THE ABS IS NON-FUNCTIONAL. AUDI HAS BEEN VERY SLOW TO REPAIR THE PROBLEM, REQUIRING A 2 WEEK WAIT JUST TO DIAGNOSE THE ISSUE. THEN REQUIRING $2300 TO MAKE A 6 YEAR OLD CAR SAFE TO DRIVE.*AK
