Known issues on the 1989 Audi 100. 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 that can lead to drive wheel power loss or front wheel lockup, sudden deceleration, and loss of vehicle control. The second covers the scissor jack supplied with the vehicle, whose trunk instruction label is incorrect, risking jack collapse and injury to anyone under or near the vehicle during use. The third covers the frontal airbag sensor and control module, which did not meet Audi's durability standards over the vehicle's lifetime and could deploy the airbag without warning, causing loss of vehicle control. Owners have filed 6 complaints for the year. The factory diagnostic and repair procedures behind each of those systems are here.

From checking the transaxle differential oil level to correcting jack usage or inspecting the airbag sensor, it keeps you on the OEM procedure for your specific 1989 Audi 100.
