Limited data — recalls on file
NHTSA has just 4 complaints on file for the 1988 Audi 90 — too few to judge reliability from owner reports alone — but one recall campaign applies to this year, so any used example should have its VIN checked for completed recall work.

Defect
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.
Consequence
IN THE EVENT OF FAILURE, THE VEHICLE'S DRIVE WHEELS COULDLOSE POWER. IN EXTREME CIRCUMSTANCES, THE FRONT WHEELS LOCK, CAUSING RAPIDDECELERATION RESULTING IN POSSIBLE LOSS OF VEHICLE CONTROL AND AN ACCIDENT.
Remedy
DRAIN AND REPLACE THE DIFFERENTIAL GEAR OIL WITH OIL HAVING HIGHER PERFORMANCE CHARACTERISTICS.
