Known issues on the 1988 5000 Quattro. Three recalls are on federal record for this model year. The first covers the transaxle: differential oil is lost over time to evaporation, and low oil levels cause premature bearing and gear wear that can lead to differential failure, with drive wheels losing power or the front wheels locking and causing rapid deceleration. The second covers the fuel tank: repeated topping off during refueling reduces expansion space, letting vapors escape near the exhaust system where they could ignite. The third covers the fuel injection system: seals can harden from heat and alcohol content in some fuels, allowing fuel to drip onto hot engine components and risk an engine compartment fire. Owners have filed 1 complaint for the year, and no technical service bulletins are logged. The factory diagnostic and repair procedures behind each of those systems are here.
From a differential oil check to a fuel line and injector seal inspection, it keeps you on the OEM procedure and the correct specification for your specific 1988 5000 Quattro.
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 ACC
Remedy
DRAIN AND REPLACE THE DIFFERENTIAL GEAR OIL WITH OIL HAVING HIGHER PERFORMANCE CHARACTERISTICS.
REPEATED TOPPING OFF OF FUEL TANK DURING REFUELING REDUCES THE EXPANSION SPACE WITHIN THE TANK ALLOWING VAPORS TO ESCAPE FROM THE CHARCOAL FILTER TO OUTSIDE RATHER THAN BEING INDUCTED INTO THE ENGINE.
Consequence
ESCAPING VAPORS COULD IGNITE BY HEAT EMITTED BY THEEXHAUST SYSTEM.
Remedy
INSTALL REDESIGNED FILLER NECK AND A NEW VENT VALVE AND HOSE FOR CHARCOAL FILTER. ALSO, STOP REFUELING WHEN PUMP NOZZLE SHUTS OFF.
FUEL INJECTION SEALS MAY HARDEN, DUE TO HIGH TEMPERATURE AND ALCOHOL IN SOME FUELS, AND ALLOW FUEL TO ESCAPE INTO THE ENGINE COMPARTMENT.
Consequence
FUEL DRIPPING ONTO HOT ENGINE COMPONENTS COULD CAUSE ANENGINE COMPARTMENT FIRE.
Remedy
REPLACE ENGINES FUEL INJECTOR SEALS WITH IMPROVED SEALS PLUS IMPROVEMENTS DESIGNED TO BETTER INSULATE THE ENGINE AGAINST FIRE RISK.
