Known issues on the 1985 Audi 4000. Two recalls are on federal record for this model year. The first covers the axle assembly: differential oil is lost over time through evaporation, and low oil levels lead to premature bearing and gear wear, which in extreme cases can lock the front wheels and cause rapid deceleration and loss of vehicle control. The second covers vehicle speed control: excessive wear of the idle stabilizer can cause idle fluctuations and unsatisfactory driveability. Owners have filed 1 complaint for the year. The factory diagnostic and repair procedures behind both systems are here.

From a differential oil check to sorting out an erratic idle, it keeps you on the OEM procedure and the correct specification for your specific 1985 4000.
