Known issues on the 1988 90 Quattro. One recall is on federal record for this model year.

Owners have filed 4 complaints for the year, and no technical service bulletins are logged. The factory diagnostic and repair procedures for the differential and transaxle are in this manual.
Whether you're checking differential oil level or working through a full transaxle service, it keeps you on the OEM procedure and correct specification for your specific 1988 90 Quattro.
