THE A4, UNLIKE ALL OTHER CARS I'VE EVER OWNED, DOES NOT HAVE 'SPLASH SHIELDS' INBOARD OF THE FRONT DISC BRAKE ROTORS. IN THE RAIN, THIS CAUSES A QUITE ALARMING PERIOD, WHEN THE BRAKES ARE INITIALLY APPLIED, OF SHEER TERROR, BECAUSE THE CAR IS NOT STOPPING! THIS HAS BEEN MADE A MANDATORY RECALL ALL ACROSS EUROPE, AND THERE, INSURANCE COMPANIES WON'T COVER YOU IF YOU REAR-END SOMEONE AND DON'T HAVE THE SHIELDS ON. I SEE NO REASON WHY AUDI WON'T ALSO CARRY THIS TO THE US, UNTIL THEY GET SUED WHEN SOMEONE GETS KILLED BECAUSE OF IT. SWITCHING TO GAS-SLOTTED BRAKE ROTORS HELPS THIS SITUATION, BUT DOES NOT ELIMINATE IT. THANKS, AND I HOPE THIS GETS TAKEN CARE OF BEFORE I HIT SOMEONE! OH, EVERY SINGLE PERSON WITH AN A4 THAT I KNOW HAS THE SAME PROBLEM.

MY 1997 AUDI A4 HAS EXPERIENCED ALMOST NON BRAKING IN COLD/WET CONDITIONS. WHEN BRAKES ARE INITIALLY APPLIED DURING THESE CONDITIONS THERE IS ALMOST ZERO BRAKING FOR 50 FEET AT 35 MPH OR LESS. I HAVE COME VERY CLOSE TO REAR ENDING A FEW CARS THAT CUT IN FRONT OF YOU. I HAVE CONTACTED AUDI OF AMERICA AND THERE RESPONSE WAS THAT NO KNOWN POOR BRAKING CONDITION EXISTS WHEN BRAKES ARE COLD/WET. YET THERE IS A NEWS BULLETIN ON AUDI'S OWN EUROPEAN WEB SITE INDICATING THAT THERE IS A PROBLEM WITH BRAKES WHEN WET. ALSO MANY READERS ON THE WWW.A4.ORG WEB SITE HERE IN THE US HAVE BEEN COMPLAINING FOR A LONG TIME. I HOPE THAT YOU WOULD PLEASE LOOK INTO THIS MATTER AS A FATALITY CAN EXIST IN THIS CASE. I HAVE OWNED MANY US/EUROPEAN/JAPANESE VEHICLES AND NEVER EXPERIENCED SUCH POOR WET BRAKING!

Official recalls

22V471000 · Air Bags:frontal:driver Side:inflator Module

Jul 1, 2022

Volkswagen Group of America, Inc. (Audi) is recalling certain 1998 Audi A8 and 1997-1998 Audi A4 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 inflator may absorb moisture, causing the inflator to explode or the air bag cushion to underinflate.

Consequence & remedy

Consequence: The inflator could explode during air bag deployment, resulting in metal fragments striking the driver or other occupants. An underinflated air bag may not properly protect the occupant. These scenarios increase the risk of serious injury or death.

Remedy: Dealers will replace the driver's air bag inflator with an alternative inflator of a different design, free of charge. Owner notification letters were sent September 21, 2021. Owners may contact Audi customer service at 1-800-253-2834. Audi's number for this recall is 69BT. The vehicles in this recall were mistakenly omitted from recall 20V-056.
