Audi S4 problems and owner complaints

THERE IS A SEVERE SAFETY PROBLEM ASSOCIATED WITH THE AUDI 94S4, OTHER MODEL YEAR S CARS AND OTHER AUDI CARS WITH THE 100 BODY. WHEN THE PLASTIC PART THAT CONNECTS THE THROTTLE BODY TO THE THROTTLE CABLE BREAKS, THE ENGINE GOES UP TO 7000 RPM (OVER RED LINE). IF IN HEAVILY CONGESTED TRAFFIC AS I WAS, THE OWNER RISKS HIS LIFE OR HIS ENGINE. SINCE I DECIDED MY LIFE AND THAT OF MY PASSENGERS WAS MORE IMPORTANT THAN THE ENGINE, I LET THE ENGINE RACE AND USED THE BRAKE TO CONTROL SPEED UNTIL I COULD SAFELY GET OFF THE BELTWAY AND ONTO A SIDE R…

EXPERIENCED A GRINDING NOISE AND VIBRATION IN THE TRANSMISSION WHILE ACCELERATING ONTO HIGHWAY FROM A STOP, SHIFTING FROM 1ST TO 2ND GEAR AT APPROX. 4500 RPM. AFTER THIS INCIDENT, THE TRANSMISISON GRINDED WHEN SHIFTING FROM 1ST TO 2ND GEAR ALL THE TIME ABOVE 3500 RPM. I CONTACTED THE DEALER AND HAD TO WAIT A WEEK FOR THEM TO SEE MY CAR. THEY KEPT THE CAR FOR A DAY TO "DIAGNOSE THE PROBLEM." THEY TOLD ME THAT 2ND GEAR WAS "SHOT" DUE TO "SHIFTING AT HIGH RPMS" OR FROM "HARD SHIFTING" AND THAT THE TRANSMISSION NEEDED TO BE REBUILT. I SAID THAT THI…

ON OR ABOUT 11/20/00 I APPLIED BRAKES WHILE DRIVING DOWN HILL. CAR ACCELERATED OUT OF CONTROL. BRAKES WOULD NOT STOP CAR, WHICH EVENTUALLY CRASHED INTO TELEPHONE POLE. I INJURED MY LEFT LEG. AUDI ADVISED ME THEY KNEW OF NO "DEFECT" THAT COULD CAUSE THIS ACCIDENT. ON 13/21/01 AS I APPLIED BRAKES TO TURN INTO A PARKING SPACE CONTIGUOUS TO A BUILDING THE VEHICLE ACCELERATED. WHEN I BOTH HEARD TO ENGINE RACING AND THE CAR ACCELERATING I FORTUNATELY SHIFTED INTO NEUTRAL AND STOPPED THE VEHICE. MY FOOT WAS NOT ON THE ACCELERATOR! I REFUSE TO DRIVE TH…

THUNKING NOISE IN FRONT SUSPENSION FOR LAST TWO YEARS WHEN I GET ON THE GAS OR ON THE BRAKES. TWO SEPARATE DEALERS TOOK THE CAR FOR A ROAD TEST AND SAID IT WAS FINE. IT HAS GOTTEN PROGRESSIVELY LOUDER AND MORE NOTICEABLE. I AM WORRIED THAT THIS COULD BE LEADING UP TO A FAILURE OF THE SUSPENSION OR STEERING.*AK

A FRONTAL COLLISION WITH ANOTHER VEHICLE AT 50 MPH. UPON IMPACT, DRIVER'S AIR BAG DID NOT DEPLOY, AND THE STEERING WHEEL CAME OFF THE STEERING COLUMN. NEITHER THE DRIVER NOR THE ONE PASSENGER WAS INJURED. BOTH PARTIES WERE WEARING SEAT BELTS.*AK *AK

IT SEEMS THAT THERE IS A MANUFACTURING DEFECT AMONG B5 PLATFORM AUDI A4 VEHICLES, WHERE EITHER THE ABS CONTROLLER IS APT TO FAIL PREMATURELY, OR THE CONNECTION BETWEEN THE CONTROLLER AND THE INSTRUMENT CLUSTER FAILS. DUE TO THE HIGH FREQUENCY OF FAILURES, IT SEEMS HIGHLY UNLIKELY THAT THE ABS CONTROLLER IS AT FAULT AND PRONE TO SUCH A HIGH FAILURE RATE. WIRING TO THE INSTRUMENT CLUSTER SEEM TO BE THE MORE LIKELY CAUSE, YET DEALERS ALMOST EXCLUSIVELY DECIDE TO POINT TO THE CONTROLLER, WHICH COSTS UPWARDS OF $1200. THIS CONDITION IS UNDOUBTEDLY…

THE ABS AND BRAKE LIGHTS ON MY DASHBOARD INITIALLY FLASHED AND BEEPED INTERMITTENTLY, BUT NOW ARE ON CONSTANTLY. UPON RESEARCHING THE ISSUE, I'VE DISCOVERED THAT THIS IS A PROBLEM EXPERIENCED MY MANY OTHER MY2000 S4 OWNERS. THIS IS A SIGNIFICANT SAFETY ISSUE, AS THERE IS THE RISK THAT BRAKES MAY LOCK UP (EVEN WHEN RELEASING THE PEDAL) UNDER BRAKING WHEN EXPERIENCING THESE SYMPTOMS. PLEASE TAKE ACTION ON THIS ISSUE. I KNOW MANY OWNERS WHO HAVE NO CHOICE BUT TO HOLD OFF ON THE REPAIR DUE TO THE AMOUNT BEING CHARGED BY DEALERS TO REPLACE THE PART …

1) THERE IS NO TRIGGERING EVENT LEADING UP TO THE FAILURE. IT JUST APPEARS OVER TIME. 2) THE LCD SCREEN IN THE INSTRUMENT CLUSTER HAS LINES OF PIXELS THAT DO NOT LIGHT UP. THIS IS CONSTANT, WITH MORE LINES OF PIXELS GOING OUT AND PERMANENTLY STAYING OUT OVER TIME. AS A CONSEQUENCE, IMPORTANT WARNING MESSAGES ARE NOT DISPLAYED OR READABLE; SUCH AS WORN OUT BRAKE PADS, FUEL LOW WARNING, WASHER FLUID LOW WARNING, ETC. IF THESE WARNINGS ARE NOT DISPLAYED, THE VEHICLE MAY RUN OUT OF GAS WITHOUT WARNING AND STALL WHILE OPERATING, OR BRAKES MAY W…

AFTER ENGINE COOLS DOWN, TIMING CHAIN RATTLE CAN BE HEARD UPON STARTING THE CAR. CHAIN RATTLE MEANS THAT PLASTIC GUIDES OR ADJUSTERS ARE WORN, AND MIGHT GO ANY SECOND. SPOKE WITH AUDI REP ONLINE, WHICH ADVISES ME THAT THIS IS NORMAL, AND EXPECTED. KNOWING BASICS OF ENGINES AND TRANSMISSION, I DIDN'T BELIEVE THAT SOMETHING IS "LIFE TIME" AND IS NOT SERVICEABLE, ESPECIALLY IF IT'S PLASTIC (WHICH TENDS TO SHRINK AND EXPAND DEPENDING ON TEMPERATURES, AND THEN HAS FRACTURES WHICH SNAPS). TWO DIFFERENT INDEPENDENT LICENSED AUDI SHOPS CONFIRMED THAT T…

BUZZING NOISE IN BACK OF CAR TURNED OUT TO BE FAULTY FUEL PUMP. AFTER SEVERAL DAYS IN SHOP THE SERVICE REP TOLD ME THAT THERE WAS ANOTHER PROBLEM -- A "BURNT" OR "CORRODED" WIRE NEAR THE FUEL PUMP AND FUEL TANK THAT COULD BE A "SAFETY ISSUE." THAT WAS 3 DAYS AGO. STILL NO UPDATE FROM THE DEALERSHIP. I AM WONDERING IF OTHERS HAVE HAD PROBLEMS WITH THE FUEL PUMP ON THE AUDI S4. I'M PARTICULARLY WORRIED BECAUSE EXPOSED WIRES NEAR A FUEL TANK SOUNDS LIKE A SERIOUS SAFETY ISSUE.
