1993 Audi S4 Problems

THIS WAS A CONSUMER CALL RECEIVED BY REGIONAL OFFICE STAFF, AND IS BEING RELAYED. VEHICLE HAS AN ACTIVE FUEL SYSTEM RECALL, AND DEALER IN SALT LAKE CITY, UT SCHEDULED REPAIR, BUT CANCELLED THE REPAIR APPOINTMENT DUE TO NOT HAVING PROPER BILLING CODE TO BE REIMBURSED FOR THE REPAIR BY THE MANUFACTURER. PLEASE CONTACT CONSUMER DIRECTLY FOR FURTHER DETAILS AND TO ASSIST HIM IN RESOLVING THIS ISSUE.

I OWN TWO OF THE ORIGINAL AUDI S4'S, BOTH 1993 MODELS. MY DAUGHTER WAS DRIVING ONE OF THESE CARS IN 2007 AND THE THROTTLE STUCK OPEN SO THAT THE ENGINE RACED UNCONTROLLABLY. SHE WAS ABLE TO PUT THE CLUTCH IN AND STOP THE CAR AND TURN THE ENGINE OFF. THEN SHE HAD THE CAR TOWED TO THE NEAREST REPAIR SHOP. IT WAS DISCOVERED THAT A PLASTIC PART ON THE TIP OF THE THROTTLE CAM HAD BROKEN OFF AND AS A RESULT THE THROTTLE CABLING MECHANISM STUCK IN THE PARTIALLY "OPEN" POSITION. I HAD THE THROTTLE CAM REPLACED WITH AN ALL STAINLESS STEEL CAM WHICH CANNOT BREAK DOWN AS A RESULT OF HEAT, AS PLASTIC OR A SIMILAR PRODUCT CAN DO. I HAD OEM CAMS REPLACED IN BOTH S4'S. AUDI DEALER WAS NOTIFIED OF THE PROBLEM IN OCTOBER 2007. I HAVE RECOMMENDED TO AUDI THAT ALL 1992-1997 S4 AND S6 MODELS BE RECALLED AND THAT ALL THROTTLE CAMS BE REPLACED WITH AN ALL STAINLESS STEEL CAM (FOR EXAMPLE, ONE FABRICATED BY 034 MOTORSPORT IN FREMONT, CA.) AT LEAST ONE OTHER INSTANCE OF UNINTENDED ACCELERATION, DUE TO FAILURE OF THE OEM THROTTLE CAM, HAS BEEN REPORTED ON THE "WEB" -- IN FACT THAT REPORT LED ME TO 034 MOTORSPORT'S SOLUTION. I KNOW I NEVER RECEIVED, FROM AUDI, A NOTICE OF THIS POTENTIAL PROBLEM. DATE SHOWN BELOW IS APPROXIMATE. I WOULD HAVE TO FIND THE TOWING BILL TO BE PRECISE. *TR

WHILE DRIVING THERE WAS A LOT OF VIBRATION IN FRONT END. ABS BRAKES WERE NOT FUNCTIONING/LOCKED UP, CAUSING VEHICLE TO VIBRATE. ALSO, FRONT LEFT WHEEL HAD SMOKE COMING FROM IT. DEALER HAD TO REPLACE ALL BRAKE ROTORS AND REAR CALIPERS. *AK

BOUGHT THE CAR FROM MY MOTHER WHO BOUGHT IT NEW JANUARY 1993 FROM HIGHLAND PARK AUDI, HIGHLAND PARK IL. NO SPECIFIC DEFECT CITED IN THE SUMMARY.
