2001 Audi A6 Common Problems, Issues, Recalls, and Reliability

• 2001 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.

• 2001 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.

• 2001 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.

• 2001 Audi A6 Flasher Relay Failure Can Cause Erratic Turn Signal Operation

  Erratic turn signal operation can be a result of a failing turn signal flasher relay which will require replacement.

• 2001 Audi A6 Check Engine Light Due to Faulty Torque Converter

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

• 2001 Audi A6 Oil Leaks From Camshaft Chain Tensioner and Valve Cover Gaskets

  Engine oil leaks are common from the valve cover gaskets and camshaft chain tensioner gasket.

• 2001 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.

• 2001 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.

• 2001 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.

• 2001 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.

• 2001 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.
