1993 Audi S4 recalls & complaints
Source: NHTSA, updated daily. Last checked 2026-10-20. Recalls apply to specific VINs — run your VIN to confirm.
2 safety recalls, most serious first
1. Fuel system
What's wrong, in plain English: Fuel lines, tank or pump. Fuel problems usually mean a leak, and leaks mean fire risk. VEHICLE DESCRIPTION: PASSENGER VEHICLES. A FUEL FEED LINE CONNECTING THE FUEL FILTER TO THE ENGINE CAN PREMATURELY AGE AND SHRINK THROUGH EXPOSURE TO HIGH UNDER HOOD TEMPERATURE CAUSED BY THE TURBOCHARGER.
What could happen: THIS CAN RESULT IN FUEL SEEPAGE AT THE CONNECTION.
The fix: DEALERS WILL REPLACE THE ENTIRE FUEL FEED LINE FROM THE FUEL FILTER TO THE ENGINE WITH A FUEL LINE OF SHRINKAGE-PROOF MATERIAL.
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 1993 S4.
- Book a repair at any authorized Audi dealer. Quote NHTSA campaign 00V068000.
- The repair is free. By US law, safety recall repairs cost the owner nothing, no matter the car's age or mileage.
- Buying this car used? Ask the seller for proof the recall was completed, or run the VIN yourself before paying.

2. Airbags
What's wrong, in plain English: The airbag system — the part that is supposed to protect you in a crash. VEHICLE DESCRIPTION: PASSENGER VEHICLES. SOME AIR BAG SENSORS DO NOT COMPLY WITH AUDI'S DURABILITY STANDARDS OVER THE LIFETIME OF THE VEHICLE.
What could happen: IN THE EVENT THE SENSOR SHOULD MALFUNCTION, THE AIR BAG RESTRAINT SYSTEM CAN INADVERTENTLY DEPLOY. DEPLOYMENT OF THE AIR BAG RESTRAINT SYSTEM WITHOUT WARNING COULD CAUSE A DRIVER TO LOSE VEHICLE CONTROL.
The fix: DEALERS WILL REPLACE THE AIR BAG SENSOR CONTROL MODULE.
