Known issues on the 1989 80 Quattro. Two 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 axle failure, a loss of drive power, and in extreme cases the front wheels locking and causing rapid deceleration and loss of vehicle control. The second covers the airbag sensor/control module, which does not meet Audi's own durability standard over the vehicle's lifetime and can malfunction in a way that deploys the airbag without warning, risking a loss of vehicle control. Owners have filed 10 complaints for the year, and no technical service bulletins are logged. The factory diagnostic and repair procedures behind both of those systems are here.
Whether you're checking transaxle fluid level or diagnosing an airbag sensor fault, it keeps you on Audi's own procedure and specification for this exact 1989 80 Quattro.
