Known issues on the 1988 Audi 90. One recall is on federal record for this model year, covering the axle assembly: the differential oil is lost over time due to evaporation, and low oil levels cause premature bearing and gear wear and eventual failure of the differential. In the event of failure, the vehicle's drive wheels could lose power, and in extreme circumstances the front wheels lock, causing rapid deceleration and possible loss of vehicle control and an accident. Owners have filed 4 complaints for the year, and no technical service bulletins are logged. The factory diagnostic and repair procedures behind that system are here.
From a differential fluid check to a routine service interval, this manual keeps you on the OEM procedure and the correct specification for your 1988 Audi 90.
