1991 Audi 4000

Component

Power Train:Axle Assembly

Consequence of 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.

Corrective Action

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.

Recall Notes

drain and replace the differential gear oil with oil having higher performance characteristics.

1986 Audi 4000

Component

Seat Belts:Front:Buckle Assembly

Consequence of Defect

rear or front right seat belt locks may not properly engage. consequence of defect: seat belts could separate in event of heavy brake application or impact and thus subject passengers to injury.

Corrective Action

Recall Notes

replace seat belts, as necessary.

1986 Audi 4000

Component

Vehicle Speed Control

Consequence of Defect

excessive wear of idle stabilizer could cause idle fluctuations.

Corrective Action

idle fluctuations could result in unsatisfactorydriveability.

Recall Notes

replace idle stabilizer.

1984 Audi 4000

Component

Service Brakes, Hydraulic:Foundation Components:Hoses, Lines/Piping, And Fittings

Consequence of Defect

under adverse weather conditions, outer rubber layer of brake hoses may become brittle and develop cracks. consequence of defect: cracks could lead to loss of brake fluid resulting in an increase in stopping distance and possibly an accident.

Corrective Action

Recall Notes

replace brake hoses as necessary.

1981 Audi 4000

Component

Fuel System, Gasoline:Fuel Injection System

Consequence of Defect

the fuel pump may stop functioning without warning. this can occur because an electrical connector in the fuse panel may overheat and interrupt the electrical circuit.

Corrective Action

Recall Notes

dealer will inspect the fuse box and its connectors for corrosion, and correct where necessary. a bypass adapter to the fuel pump electrical circuit will be installed.

1981 Audi 4000

Component

Structure:Frame And Members

Consequence of Defect

rear bumper system on certain vehicles may not have been properly welded during assembly. in the event of a rear end collision, the right side bumper supportor could break loose, damage the fuel tank and allow fuel to leak.

Corrective Action

Recall Notes

a reinforcement plate will be installed, if necessary, to prevent fuel tank damage. work will be performed at no cost to owners.

1981 Audi 4000

Component

Service Brakes, Hydraulic:Foundation Components:Disc:Caliper

Consequence of Defect

on certain vehicles, porous spots may have developed on the interior surface of the threaded hole for the brake hose during the moulding process. these spots allow brake fluid to seep from the calipers during heavy brake applications.

Corrective Action

Recall Notes

both front brake calipers will be inspected for brake fluid seepage and will be replaced, if necessary, without charge.
