Known issues on the 1991 Audi 100. Four 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 the drive wheels to lose power or the front wheels to lock, risking rapid deceleration and loss of control. The second covers the rear speaker amplifiers: a leaking capacitor can create an unwanted conductive path and an overheating and fire risk. The third covers the trunk's scissor jack instruction label, which is incorrect for the jack supplied and can lead to the jack collapsing and injuring anyone under or near the vehicle. The fourth covers the front air bag sensors, which do not meet Audi's durability standards over the vehicle's lifetime and can cause the air bag to deploy without warning. 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 inspecting the amplifier or air bag sensor wiring, it keeps you on the OEM procedure and the correct specification for your specific 1991 Audi 100.
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.
