1998 Audi A6 Common Problems, Issues, Recalls, and Reliability

  • 1998 Audi A6 Digital Display on Instrument Cluster May Fail

    The digital display portion of the instrument cluster may fail. Our technicians tell us the entire instrument cluster will need to be replaced to correct this concern.

  • 1998 Audi A6 No Start after Refueling and Popping Noise from Trunk

    Popping sounds from the rear of the vehicle may be heard moments after starting the engine, or when slowing to a stop. This noise is from the leak detection pump filling the fuel tank with air, and releasing to retest the system when it finds a fault. The sequence of faults identifying this issue are as follows:

    • Succession of loud pops from rear of vehicle
    • Pops go away, and fuel economy decreases
    • Check engine light illuminates
    • OBD trouble code P2404 and/or P0441 is stored
    • Engine will not start after refueling (must crank for over 30 seconds)
    • Vibration when slowing to a stop

    The cause is a valve which is mounted on the front of the intake manifold, commonly called the N80 valve, or EVAP system purge valve. The valve is designed to open under specific circumstances, but a worn valve will remain open at all times, preventing the pressurization of the fuel tank.

    Correction of the issue is to replace the N80 valve with the latest revision.

  • 1998 Audi A6 Premature Wear in Multi-Link Suspension Components May Cause Noise

    Premature wear in various multi-link suspension components can cause noises that are difficult to diagnose. Worn suspension parts can also cause uneven tire wear and create steering alignment problems.

  • 1998 Audi A6 Check Engine Light Due to Faulty Torque Converter

    A problem with the torque converter can cause the Check Engine Light to illuminate.

  • 1998 Audi A6 ABS Light Due to ABS Control Module Failure

    The anti-lock brake system (ABS) control module may fail causing the ABS light to illuminate. Failed modules should be replaced to restore ABS operation.

  • 1998 Audi A6 Rainwater May Accumulate in Plenum Tray Due to Clogged Drains

    Clogged drains can allow rainwater to accumulate in the plenum tray (at the base of the windshield). The water may leak into the vehicle's interior, brake booster, or electrical components, which can lead to major problems. Our technicians recommend keeping the tray clear of leaves, pine needles, and other debris.

  • 1998 Audi A6 Inspect CV Boots and Joints at Each Service

    Our technicians recommend having the constant velocity (CV) boots and CV joints inspected at each service. Servicing torn CV boots early can prevent the need to replace the CV half shaft or CV joint.

  • 1998 Audi A6 Inspection of Water Pump and Timing Belt

    The water pump may fail resulting in engine overheating and possible timing belt damage. Overheating and/or timing belt failure can result in very expensive engine repairs. As a precaution, it is recommended to inspect the timing belt and water pump at regular intervals.

  • 1998 Audi A6 Water From Clogged Sun Roof Drains May Damage Control Modules

    Clogged sunroof drains can allow water to enter the interior and accumulate under the carpet where various control modules are mounted. Over time, the accumulated moisture can damage the control modules.

  • 1998 Audi A6 Oil Leaks at Valley Pan Gasket and Head Gasket are Common

    An External oil leak may develop from the valley pan gasket (under the intake manifold ) and/or the head gasket .
