Known issues on the 1989 100 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 the resulting low oil level causes premature bearing and gear wear, which can lead to drive wheel power loss or, in extreme cases, the front wheels locking and causing rapid deceleration and loss of vehicle control. The second covers the jack supplied with the vehicle: an incorrect instruction label can lead to improper use and jack collapse, risking injury to anyone under or near the vehicle. The third covers the frontal air bag sensor and control module, which does not comply with Audi's durability standards over the vehicle's lifetime and can malfunction, causing the air bag to deploy without warning and risk loss of vehicle control. Owners have filed 6 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 inspecting the air bag sensor wiring, it keeps you on the OEM procedure and the correct specification for your specific 1989 100 Quattro.
