1992 Audi 100 Complaints

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 BRAK...

RUNAWAY THROTTLE. UNCOMMANDED ENGAGEMENT OF CRUISE CONTROL? WOULD NOT RESPOND TO BRAKE OR SHUTTING CRUISE CONTROL OFF ON STEERING COLUMN STALK SWITCH. VERY DANGEROUS!!! ALMOST CAUSED A CRASH, VERY INEFFECTIVE BRAKING WITH ENGINE TRYING TO KEEP CAR GOING AT ABOUT 55 MPH, BUT I MANAGED TO PULL OVER AND SHUT CAR OFF. I PULLED THE CRUISE CONTROL FUSE AND PROBLEM HAS NOT REAPPEARED. I AM AN ELECTRICAL ENGINEER.

DANGEROUS UNCOMMANDED ACCELERATION. I SUBMITTED A COMPLAINT EARLIER TODAY THAT SAID I THOUGHT IT WAS A CRUISE CONTROL PROBLEM BUT IT ISNT. IT HAPPENED AGAIN TODAY WITH THE CC FUSE PULLED!!! IT WAS PRECEDED BY A FUNNY FEELING IN THE BRAKES, LIKE NOT ENOUGH VACUUM BOOST, THEN RADICAL ENGINE ACCELERATION EVEN WITH MY FOOT OFF THE GAS PEDAL. I PUT THE CAR IN NEUTRAL, THE TACH REDLINED AND THEN I SHUT OFF THE IGNITION. STARTED IT AND IT DID IT AGAIN. I AM AN ENGINEER AND NEVER BELIEVED THE STORIES ABOUT AUDIS AND UNINTENDED ACCELERATION... BUT NOW I KNOW IT CAN HAPPEN AND IT IS SUPER DANGEROUS!!!!

THIS IS A FOLLOW-UP TO COMPLAINT 10146994 FILED ON 1-05-06. IT CONCERNS THE RUSTED OUT FUEL LINES ON MY 100CS WAGON FROM AUDI. I HAVE STARTED TO TEAR DOWN TO REPLACE THE LINES, AND SEE WHERE THE MAIN ISSUE SEEMS TO BE. AT ALL OF THE MOUNTING POINTS FOR THE FUEL LINES ON THE UNDERBODY FROM THE FUEL TANK TO THE ENGINE COMPARTMENT, THE LINES HAVE RUSTED THROUGH. THERE WERE ACTUALLY 8 LEAKS INSTEAD OF THE THREE THAT I ORIGINALLY THOUGHT WERE PRESENT. DUE TO THE RUBBER MOUNTS BEING COMPRESSED AROUND THE LINES, NOT ALL OF THEM SHOWED THE LEAKS UNTIL THE MOUNTING BRACKETS WERE REMOVED. IT APPEARS THAT THE RUBBER MOUNTS THAT ARE USED HOLD WATER ETC. ALLOWING THE FUEL LINES TO BE PRONE TO RUST THROUGH IN THESE AREAS. IN CHECKING ONLINE FORUMS, IT SEEMS TO HAVE BEEN A PROBLEM WITH PREVIOUS MODEL YEARS AS WELL. I HAVE FOUND NUMEROUS REPORTS OF PEOPLE REPLACING RUSTED FUEL LINES ON AUDI MODELS. I HAVE NOT MADE A BIG ISSUE OF IT WITH AUDI AS OF YET, ONLY CONTACTED THEM TO THE POINT THAT TH...

RECENTLY PURCHASE A USED 1992 AUDI 100 CS WAGON. WHEN I GOT IT HOME AND IN THE GARAGE, THERE WAS A TERRIBLE GASOLINE ODOR. I NOTICED THE PUDDLE ON THE FLOOR, AND GOT UNDER THE CAR TO CHECK IT OUT. SURE ENOUGH, THERE WAS GAS LEAKING FROM THE FUEL LINES IN MULTIPLE PLACES FROM THE TANK TO THE ENGINE BAY. ALL OF THE LINES ARE SEVERELY RUSTED, TO THE POINT THAT IT HAS SPRUNG LEAKS. IN CHECKING AUDI ONLINE FORUMS, IT SEEMS TO BE A COMMON PROBLEM, WITH MOST PEOPLE SPLICING IN SECTIONS OF HOSE TO KEEP THEIR CARS RUNNING WITHOUT HAVING A PERSISTENT GAS LEAK. I WAS SUPRISED TO SEE THAT THE ONLY FUEL LINE RECALL ON THESE UNITS WAS 1993 AND 1994 MODELS. LUCKILY, I CAUGHT THIS THING BEFORE THEIR WAS AN IGNITION SOURCE TO CAUSE A FIRE. CURRENTLY, I AM PLANNING ON USING THE EVER POPULAR TUBE SPLICE UNTIL I DECIDE IF I WILL BEND MYSELF A NEW SET OF LINES SINCE REPLACEMENTS SEEM TO BE HARD TO COME BY. *NM
