2002 Audi A4 Common Problems, Issues, Recalls, and Reliability

• 2002 Audi A4 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.

• 2002 Audi A4 Ignition Coil, Ignition Wires, and Spark Plugs May Fail

  An ignition coil or spark plug may fail unexpectedly resulting in an engine misfire and possible illumination of the Check Engine Light . Vehicles equipped with spark plug wires may also develop a misfire caused by a failed spark plug wire.

• 2002 Audi A4 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.

• 2002 Audi A4 Check Engine Light Due to Vacuum Leaks, Oxygen Sensor, or Catalytic Converter Fault

  Vacuum leaks, oxygen sensor failure, and catalytic converter efficiency faults can cause the Check Engine Light to illuminate.

• 2002 Audi A4 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.

• 2002 Audi A4 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.

• 2002 Audi A4 Check Engine Light Due to Faulty Torque Converter

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

• 2002 Audi A4 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.

• 2002 Audi A4 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.

• 2002 Audi A4 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.

• 2002 Audi A4 Use correct oil/filter to prevent sludge accumulation

  To avoid sludge accumulation inside the engine, our technicians recommend using the proper synthetic oil with the appropriate oil filter .

• 2002 Audi A4 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.

• 2002 Audi A4 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.

• 2002 Audi A4 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.

• 2002 Audi A4 Maintain fuel quality to avoid misfires and CEL illumination

  Fuel quality must be maintained to avoid engine misfire problems; the misfires may cause the Check Engine Light to illuminate.

• 2002 Audi A4 Oil leaks from camshaft drive pulleys and variable valve timing hydraulics

  Oil leaks from the camshaft drive pulleys and variable valve timing hydraulics are common. If the variable valve timing hydraulics is leaking, the Check Engine Light may illuminate from inaccurate valve timing.
