Unit price
This 1990 Audi 80 factory service and repair manual is built around the Base Sedan 4-Door and its 2.0L l4 (engine code 3A), so the specifications and repair sequences inside are the ones Audi published for that exact powertrain rather than a generic figure pulled from a similar model year.
Engines covered
- 2.0L inline-four (121 cu in) — SOHC, naturally aspirated, gasoline
Body styles covered
- 4-door sedan
Trims covered
- Base
Known issues on the 1990 Audi 80. Three recalls are on federal record for this model year. The first covers the transaxle differential, where the oil is lost over time to evaporation; the resulting low oil level causes premature bearing and gear wear that can lead to drive wheel power loss or, in extreme cases, sudden front wheel lockup and loss of vehicle control. The second covers the front airbag sensor, which can fail to meet durability standards over the vehicle's lifetime and inadvertently deploy the airbag without warning. The third covers the steering column anti-theft lock, where an improperly manufactured bolt can break under force and leave the steering wheel locked after the ignition is turned, causing 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 transaxle oil check to an airbag sensor inspection or steering lock service, it keeps you on the OEM procedure and the correct specification for your specific 1990 Audi 80.
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.
