2001 Audi S4 recalls & complaints
Source: NHTSA, updated daily. Last checked 2026-10-18. Recalls apply to specific VINs — run your VIN to confirm.
1 safety recall, most serious first
1. Airbags
What's wrong, in plain English: The airbag system — the part that is supposed to protect you in a crash. 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.
What could happen: 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.
The fix: 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.
What to do
- Check whether your car is affected: enter your 17-digit VIN at nhtsa.gov/recalls. A recall covers specific VINs, not every 2001 S4.
- Book a repair at any authorized Audi dealer. Quote NHTSA campaign 21V470000 (manufacturer code 69CJ).
- The repair is free. By US law, safety recall repairs cost the owner nothing, no matter the car's age or mileage.
- Manufacturer hotline: 1-800-253-2834.
- Buying this car used? Ask the seller for proof the recall was completed, or run the VIN yourself before paying.

I took the vehicle into the dealer (Westwood Audi) for a Safety Recall repair as requested by Audi. It was for a Driver Front Airbag Inflator replacement. The work was done but when the car was returned the airbag warning light was on.

I JUST HAPPENED TO LOOK UP RECALLS AND SAW THE COMPLAINTS ON THE AUDI S4 2001. I NOTICED MY CAR WASN'T THE ONLY ONE WHERE THE INSTRUMENT CLUSTER HAS LOST PIXELS AND ENDS UP UNREADABLE FOR ALL WARNINGS AND MANUFACTURER PROGRAMMED SAFETY WARNINGS. IT HAS BEEN LIKE THIS FOR YEARS AND DID ASK MY DEALER HOW MUCH IT WOULD COST TO FIX IT AND IT WAS INSANE. IT IS…

COLD START ON A COLD JANUARY MORNING (5 DEGREES F); UPON STARTING THE CAR THE AIR BAG WARNING LIGHT CAME ON AND WOULD NOT SHUT OFF. RESEARCH (DISCUSSIONS WITH THE DEALER AND AIR BAG REPAIR BUSINESSES) INDICATE THAT THIS IS A VERY COMMON DEFECT FOR AUDI S4, MODEL YEAR 2001 AND THAT TO REPAIR THE PROBLEM THE AIR BAG CONTROL MODULE (COMPUTER) WOULD NEED TO BE…

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 O…
