NHTSA Complaint #10215382 — 1992 AUDI 100

92 AUDI 100S, STUCK THROTTLE AND BRAKE BOOST FAILURE, PREVIOUSLY REPORTED. FOUND THE PROBLEM AND AM POSTING IT HERE. THIS CAN KILL SOMEONE. I HOPE NHTSA DOES SOMETHING. AUDI USA WILL NOT. SEE BELOW: FOUND THE PROBLEM. MANGLED PLASTIC DEBRIS IN THE THROTTLE BODY THAT WOULD HANG UP THE PLATE INTERMITTENTLY. SHAME ON ME FOR CALLING IT ACCELERATION WHEN IT WAS ACTUALLY A STUCK THROTTLE. WHAT I LEARNED IS THAT THE SMALL BRIEF THROTTLE STABS YOU DO TO KEEP GOING UPHILL OR IN TRAFFIC CAN RESULT IN VERY HIGH RPMS IF THE THROTTLE STICKS AT MAX EXCURSION. IT MAKES YOU THINK THE ENGINE IS ACCELERATING. SHAME ON AUDI FOR NEVER EXAMINING THE THROTTLE BODY AND IGNORING THE PROBLEM POSED BY THE DISINTEGRATING PLASTIC NECK ON THE VALVE I MENTIONED IN EARLIER POSTS. THE DISINTEGRATION OF THAT THIN PLASTIC NECK APPARENTLY CAN RESULT IN SIMULTANEOUS STUCK THROTTLE (FROM DEBRIS GETTING SUCKED INTO THROTTLE BODY AND PREVENTING THE THROTTLE PLATE FROM RETURNING TO IDLE POSITION) AND LOSS OF BRAKE BOOST THROUGH THE VACUUM LEAK CAUSED BY THE BROKEN NECK. BTW, THE BRAKES WOULD NOT STOP THE CAR ON THE LAST RUNAWAY (ABOUT 5500 RPM), JUST GOT IT DOWN TO ABOUT 20 MPH EVEN WHEN I WAS STANDING ON THEM, HAD TO SHIFT INTO NEUTRAL (WHICH TOOK THE RPMS TO REDLINE AND LIMITER) AND TURN OFF THE KEY. THAT REALLY SURPRISED ME. THIS PROBLEM COULD EASILY KILL SOMEONE. I HAVE NOTIFIED AUDI USA AND NHTSA BUT NOBODY HAS TAKEN ANY ACTION. I DON'T KNOW WHAT MORE I CAN DO TO PREVENT A TRAGEDY. REMEMBER, TWO OTHERS HAVE REPORTED RUNAWAY/ STUCK THROTTLES ON 92 100S. HOPEFULLY THE DEBRIS WOULD EVENTUALLY GET SUCKED OUT OF THE THROTTLE BODY AND CHEWED UP IN THE ENGINE, BUT MINE DIDN'T. IT HAD TO BE FOUND AND DISLODGED MANUALLY. WHILE IT REMAINS IN THE THROTTLE BODY, IT IS A DISASTER WAITING TO HAPPEN. *TR
