IN SEARCHING FOR COMPLAINTS FILED FOR 2001 AUDI A4'S I NOTICED A NUMBER RELATED TO VERY POOR BRAKING IN WET WEATHER. I EXPERIENCED THE SAME PROBLEM WITH MY 2001 A4. AUDI DOES HAVE A SOLUTION FOR THIS PROBLEM. THE ROTOR BACKING PLATES MUST BE REPLACED WITH A DIFFERENT DESIGN. WHEN I BROUGHT IT INTO THE DEALER FOR ROUTINE SERVICE AND MENTIONED THE PROBLEM NO ONE IN THE DEALERSHIP WAS FAMILIAR WITH THE PROBLEM. A FACTORY REP. WAS VISITING THE DEALERSHIP AT THE TIME AND WAS FAMILIAR WITH THE PROBLEM. HE ORDERED NEW BACKING PLATES WHICH, I AM TOLD, CAN ONLY BE ORDERED BY A FACTORY REP. IT TOOK 3 MONTHS FOR THE PARTS TO REACH THE DEALERSHIP. I HAVEN'T HAD THE PROBLEM SINCE THE NEW BACKING PLATES WERE INSTALLED.*AK
INTERMITENT COMPLETE BRAKE FAILURE. HAS HAPPENED 3 TIMES THE WEEK OF 6/27/03. DEALER CAN NOT REPLICATE PROBLEM AND IS MAKING ME TAKE CAR OUT OF SERVICE AREA. THE DEALER ADMITS THEY WOULD NOT DRIVE THE CAR WITH THIS PROBLEM AND I DON'T KNOW WHAT TO DO NEXT. *NLM
SCREEN ON THE RADIO FLASHES INTERMITTENTLY, CAUSING YOU TO LOOK AWAY FROM THE ROAD EXPECIALLY AT NIGHT. IT COULD BE SOME SORT OF SHORT WHICH I BELIVE COULD LEAD TO FIRE.*AK
FAILURE OF IGNITION COIL. CAR SPUTTERS. AUDI ONLY REPLACING THE COIL THAT MALFUNCTIONED LEAVING THE REST OF THE CYLINDERS SUBJECT TO THE SAME DANGEROUS FAILURE, AS ALL COILS OBVIOUSLY WERE THE SAME WHEN INSTALLED AT FACTORY AND THEREFORE ALL ARE POTENTIALLY FAULTY. *NLM
THE CONSUMER WAS EXITING THE FREEWAY WHEN THE IGNITION COIL FAILED. THERE WAS A SIGNIFICANT LOSS OF POWER. SCC *JB

I AM PRESENTLY LEASING THE AUDI A4 1.8T. THE CAR HAS DIED ON THREE OCCASSIONS AND AUDI TELLS ME THAT THIS WAS DUE TO THE COIL SPRING PROBLEMS THEY HAVE BEEN HAVING. ON THE FIRST TWO OCCASSIONS THERE WAS NO "WARNING INDICATOR" OR "CHECK ENGINE LIGHT." THEY SEEM TO INDICATE THAT THERE IS SOME SORT OF WARNING BEFORE THIS PROBLEMS HAPPENS, BUT IN MY CASE THERE WAS NOT. THE FIRST TWO TIMES THIS HAPPENED TO ME THE CAR JUST DIED WHILE DRIVING AT HIGHWAY SPEEDS AND WOULD NOT RESTART. THERE WAS ABSOLUTELY NO WARNING OR LIGHT TO TELL ME SOMETHING WAS WRONG WITH MY CAR. THE THIRD TIME IT HAPPENED I DID HAVE THE LIGHT FLASH AND THE CAR RIDE ROUGH. THIS CAR IS ABSOLUTLY DEADLY. I WAS FORTUNATE ENOUGH THE FIRST TWO TIMES TO BE ABLE TO PULL OFF THE ROAD. DO NOT LET AUDI AND VW FOOL YOU INTO THINKING THAT THERE IS ALWAYS A WARNING BEFORE THIS HAPPENS. THE CAR IS DEADLY AND SOMETIMES THERE IS NO WARNING WHEN IT IS GOING TO DIE. FOR INCIDENT DATE I PUT THE FIRST INCIDENT ONLY.

AN IGNITION COIL ON MY 2001 AUDI A4 FAILED, CAUSING AN EXTREME LOSS OF POWER, POOR STEERING AND BRAKING. THE POTENTIAL FOR AN ACCIDENT EXISTS, ESPECIALLY IF DRIVING AT A HIGHER SPEED, OR IN POOR WEATHER CONDITIONS (AS I WAS). THE DEALER WAS AUTHORIZED TO ONLY REPAIR THE 1 FAILED COIL, AND I AM AT RISK FOR FURTHER FAILURES, A SAFETY CONCERN FOR ME.
ESPECIALLY DURING HIGHWAY DRIVING THE BRAKING SYSTEM DOES NOT INITIALLY APPLY ANY MEANINGFUL STOPPING POWER WHEN DRIVING IN WET CONDITIONS. THIS RESULTS IN A 1-2 SECOND DELAY IN ACTUAL SLOWING WHEN APPLYING BRAKES IN THE WET.

121V470000 · Air Bags:frontal:driver Side:inflator Module
Jun 23, 2021
Volkswagen Group of America, Inc. (Volkswagen) is recalling certain 2000-2001 Audi TT Coupe, TT Roadster, 2000-2002 A4, and S4 vehicles equipped with Non-Azide Driver Air Bag Inflators (NADI) that do not contain phase stabilized ammonium nitrate (PSAN) propellant. Due to a manufacturing issue, the NADI inflators may absorb moisture, possibly causing the air bag to deploy improperly in the event of a crash.
Consequence & remedy
Consequence: In the event of a crash necessitating air bag deployment, the air bag may not properly protect the occupant, increasing the risk of serious injury or death.
Remedy: Dealers will replace the driver frontal airbag inflator with an alternative inflator, free of charge. Owner notification letters were mailed November 2, 2021. Owners may contact Audi customer service at 1-800-253-2834. Volkswagen's number for this recall is 69CJ.
