1999 Audi A6 problems

What is wrong

Volkswagen Group of America, Inc. (VW) is recalling certain 2000-2001 TT Roadster, 2000 TT Coupe, 1999 Audi A8, 1998-2000 Audi A6, and 1999-2000 Audi A4 vehicles equipped with Non-Azide Driver air bag Inflators (NADI) that do not contain phase stabilized ammonium nitrate (PSAN) propellant. Due to a manufacturing issue, the NADI inflators may absorb moisture, possibly causing the air bag to deploy improperly in the event of a crash.

Risk

Remedy

Dealers will replace the driver frontal air bag inflator with an alternative inflator when the parts become available, free of charge. Owner notifications were mailed September 21, 2021. Owners may contact Audi customer service at 1‑800‑253‑2834. Volkswagen's number for this recall is 69BT.

Recall number 20V056000 · Recall details

What is wrong

On certain passenger vehicles equipped with halogen low beam headlights, certain connector pins in the headlight switch connector come into contact with each other causing a short circuit. Note: vehicles with xenon low beam headlights are not affected because the circuit in these vehicles contains a fuse, which precludes excessive current flow in the case of a short circuit. Audi s6 and s6 avant vehicles are all equipped with xenon low beam headlights and, therefore, are not longer affected by this recall.

Risk

This condition could lead to overheating or fire.

Remedy

Dealers will reroute the wiring harness by installing a jumper wiring harness. The recall began on december 16, 2006. Owners may contact audi at 1‑800‑822‑2834.

EA04017

Complaints received by odi and audi allege that, in extreme cold weather, the throttle may unexpectedly fail to return to idle when the accelerator pedal is released, making it difficult to stop the vehicle.in march of 2004, audi performed a series of tests to investigate the possible causes of throttle icing.audi concluded that under certain driving conditions - only short distance trips over several weeks where coolant temperature remains below 70?c (158?f) - water may accumulate in the motor oil. Water that has accumulated in the motor oil will evaporate after the engine oil temperature exceeds 70?c (158?f) and could, within 15 to 20 minutes of driving at a constant speed with an outside temperature below -20?c (-4of), cause ice to form in the throttle body.according to audi, this condition occurs at relatively low throttle settings and results in throttle sticking at positions that can be controlled by braking.during typical vehicle usage (mixture of short and long distance driving) this phenomenon is not expected to occur.this investigation has been upgraded to an engineering analysis.

PE04023

The subject vehicles are equipped with a knee bolster located under the dash, near the drivers knees.a wiring harness is also located in the dash, in that same area.audi's analysis of 39 vehicles indicated that the knee bolster was rubbing against that wiring harness.over time the harness sheathing wears away and the wires come into contact with the metal knee bolster, resulting in a fire. Audi will conduct a safety recall on an expanded scope of audi a6 vehicles, to add a plastic cap to the top of the knee bolster bracket, which will prevent abrasion to the wiring harness. Audi will recall 186,000 my 1998-2004 audi a6 vehicles.odi is aware of a total of 24 warranty, field and consumer reports for these vehicles.the recall is identified by the federal safety agency number 04v‑133.

PE03035

This pe was opened based on four odi complaints that the steering wheel overheats. Vw has shown that moisture and prespiration permeate the steering wheel cover causing the heating element to corrode.this corrosion may cause a small, localized area of the steering wheel to experience a brief duration of overheating.there are no reports of the steering wheel sustaining combustion. The investigation has found no occurrences of severe burning and no consumers required medical attention. A safety-related defect has not been identified at this time and further use of agency resources does not appear to be warranted.accordingly this investigation is closed.the closing of this investigation does not constitute a finding by the federal safety agency that no safety-related defect exists.the agency reserves the right to take further action if warranted by the circumstances.
