BRAKES POWER ASSIST FAIL AT / JUST AFTER STARTUP WHEN SELECTING REVERSE OR DRIVE WHILE THE AIR CONDITIONING IS ON. I REPORTED THE PROBLEM TO THE AUDI EXCHANGE IN HIGHLAND PARK, IL LAST YEAR. THEY WERE UNABLE TO REPRODUCE THE PROBLEM, AT THE TIME AS I WAS UNAWARE THAT IT ONLY OCCURRED WHEN THE A/C WAS ON AND AT LOW SPEED AFTER INITIAL START UP. THIS OCCURRED AGAIN THIS SUMMER WHEN I WAS TRYING TO MOVE OUT OF A PARKING SPOT AND WAS UNABLE TO STOP. THE RESULT WAS THAT I HIT ANOTHER CAR AT LOW SPEED CAUSING NO DAMAGE TO EITHER.
CAR HAS ONLY 62,000 MILES, BUT ANTI-LOCK BRAKE SYSTEM CONTROLLER FAILED. MANUFACTURER REFUSED TO REPLACE; REPLACED AT MY EXPENSE. *JB
FAULTY ABS CONTROL MODULE...CAUSE LOSS OF ABS BRAKING IN 2000 AUDI A4 WITH ON 60K MILES. THIS HAS CAUSE MANY CLOSE CALLS AS IT IS $1500 TO REPAIR. *AK

221V470000 · Air Bags:frontal:driver Side:inflator Module
Jun 23, 2021

(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.
