LIKE MANY OTHER PEOPLE WHO OWN AN AUDI S4 WITH 50,000 MILES, I AM HAVING BRAKE LIGHT ISSUES. ONLY MINE ARE MUCH MORE SEVERE THAT WHAT I HAVE READ THUS FAR. I TOOK MY CAR IN FOR IT'S 60000, AND HAD THE MECHANIC CHECK THE BRAKE LIGHT. LEADING UP TO THE REPAIR, I HAD BEEN *LOSING BRAKE FLUID* ALMOST MONTHLY. THIS SHOULD NEVER HAPPEN, FOR ANY REASON. BUT, MY MECHANIC TOOK THREE HOURS AND DISCOVERED THAT THE BATTERY WAS LEAKING SULFURIC ACID ONTO MY BRAKE LINE, MY POWER STEERING LINE, AND MY CLUTCH LINE. HE STATED, "ONLY A MECHANICAL MORON WOULD HOUSE THE METAL AND STEAL CABLES UNDERNEATH SULFURIC ACID." CONSEQUENTLY, I CANNOT DRIVE MY CAR ANY MORE AND THE REPAIRS INLCUDE THE TAKING OUT OF THE ENTIRE ENGINE TO GET TO THE SOURCE, WHICH MAY/MAY NOT BE ABLE TO BE FIXED. MECHANIC STATED THAT THIS SHOULD BE A RECALL ISSUE, AND THAT THE SAFETY ISSUE ON THIS TYPE OF DESIGN-FLAW IS OBVIOUS AND CERTAIN. I EXPECT AUDI WILL NOT COVER THIS DEFECT, CAUSING ME TO SHELL OUT, ARE YOU READY FOR THIS, 2-3,000 BUCKS TO GET IT REPLACED. [XXX] THE MAN. I'LL POST MORE WHEN I KNOW MORE.*AK INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6). *TR

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 THIS WAS RIDICULOUS AND THAT I WANTED A NEW TRANSMISSION. THEY SAID THAT AUDI WOULD ONLY AUTHORIZE THEM TO REBUILD MY UNIT. THEY ALSO INFORMED ME THAT IF THIS HAPPENED AGAIN, I WOULD HAVE TO PAY FOR THE REPAIRS MYSELF AND THAT I WOULD NO LONGER BE COVERED UNDER WARRANTY. IT DISTURBS ME HOW A CAR MANUFACTURER'S TRANSMISSION COULD NOT HOLD UP TO THE POWER OUTPUT OF THE ENGINE AND THAT THE CAR SHOULD NOT BE SHIFTED "HIGH" OR "HARD". WHEN THE REPAIRS ARE COMPLETED, MUST I THEN BABY THIS PERFORMANCE AUTOMOBILE AND FEAR SHIFTING ABOVE 3500 RPM (HALF OF THE ENGINE'S REDLINE RPM)? ALSO, I CANNOT UNDERSTAND HOW MY WARRANTY WILL NOT COVER A COMPONENT IF IT BREAKS TWICE. TO ME, THAT SOUNDS LIKE A DEFECT. I AM NOW WAITING FOR THE DEALER TO CONTACT ME WHEN THE NECESSARY PARTS ARRIVE. *AK

21V470000 · 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.
