Engines covered
- 2.3L inline-five — SOHC, naturally aspirated, gasoline
Body styles covered
- 4-door sedan
Trims covered
- Base
Known issues on the 1990 80 Quattro. Three recalls are on federal record for this model year. The first covers the transaxle: differential oil is lost over time to evaporation, and low oil levels can cause premature bearing and gear wear and eventual failure of the differential, which can rob the drive wheels of power or, in extreme cases, lock the front wheels and cause rapid deceleration and loss of vehicle control. The second covers the front airbag sensors, which do not meet Audi's durability standards over the life of the vehicle and can malfunction, causing the airbag to deploy without warning and risk a loss of vehicle control. The third covers the steering column anti-theft lock: improperly manufactured lock bolts can break under force, leaving the steering wheel locked even after the ignition is turned, for a total loss of steering control. Owners have filed 10 complaints for the year, and no technical service bulletins are logged. The factory diagnostic and repair procedures behind each of those systems are here.
From a differential oil check to an airbag sensor diagnosis or a steering lock inspection, it keeps you on the OEM procedure and the correct specification for your specific 1990 80 Quattro.
THE DIFFERENTIAL OIL OF THE TRANSAXLE IS LOST OVER TIME DUE TO EVAPORATION. LOW OIL LEVELS CAUSE PREMATURE BEARING AND GEAR WEAR AND EVENTUAL FAILURE OF THE DIFFERENTIAL.
Consequence
IN THE EVENT OF FAILURE, THE VEHICLE'S DRIVE WHEELS COULDLOSE POWER. IN EXTREME CIRCUMSTANCES, THE FRONT WHEELS LOCK, CAUSING RAPIDDECELERATION RESULTING IN POSSIBLE LOSS OF VEHICLE CONTROL AND AN ACC
Remedy
DRAIN AND REPLACE THE DIFFERENTIAL GEAR OIL WITH OIL HAVING HIGHER PERFORMANCE CHARACTERISTICS.
VEHICLE DESCRIPTION: PASSENGER VEHICLES. SOME AIR BAG SENSORS DO NOT COMPLY WITH AUDI'S DURABILITY STANDARDS OVER THE LIFETIME OF THE VEHICLE.
Consequence
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 CONT
Remedy
DEALERS WILL REPLACE THE AIR BAG SENSOR CONTROL MODULE.
IMPROPERLY MANUFACTURED STEERING LOCK BOLTS COULD BREAK IF DRIVER APPLIES EXCESSIVE FORCE TO A LOCKED STEERING WHEEL IN AN ATTEMPT TO DISENGAGE THE STEERING LOCK.
Consequence
BOLT BREAKAGE WOULD CAUSE STEERING WHEEL TO REMAIN LOCKED EVEN AFTER THE DRIVER TURNS THE IGNITION KEY AND ATTEMPTS TO MOVE THE CAR; THIS TOTAL LOSS OF STEERING CONTROL COULD RESULT IN AN ACCIDENT.
Remedy
REPLACE COMPLETE STEERING LOCK ASSEMBLY, INCLUDING A MODIFIED LOCK BOLT.
