Tap a recall to see the problem, the risk and the fix.

Fuel system, other:storage:tank assemblyMay 3, 2011 · NHTSA campaign 11V267000 · 5,992 vehicles

Problem: Volkswagen is recalling certain model year 2001-2004 audi a6, model year 2002-2003 s6 and model year 2003 rs6 vehicles equipped with 4.2l engines and manufactured from june 19, 2001, through june 8, 2004. The aging of the plastic material in the fuel tank rollover valve combined with bending stress from the aluminum ventilation line to the rollover valve nipple may lead to cracking of the nipple. If this happens, a fuel leak may result.

Risk: A fuel leak in the presence of an ignition source could lead to a vehicle fire.

Fix: Dealers will reinforce the nipple on the rollover valve to prevent leakage or repair the cracking at the nipple. The recall is expected to begin during june 2011. Owners may contact audi at 1-800-822-2834.

Electrical systemJun 5, 2006 · NHTSA campaign 06V198000 · 70,512 vehicles

Problem: 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.

Fix: 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.

Electrical systemMar 18, 2004 · NHTSA campaign 04V133000 · 172,866 vehicles

Problem: On certain passenger vehicles, if a driver's knees push against the knee bolster (crash element) located under the dashboard, it can contact the headlight switch wiring harness, and an electrical short could occur.

Risk: A fire could originate in the left dashboard area.

Fix: Dealers will replace all five tires. Owner notification began on september 19, 2003. Owners who take their vehicles to an authorized dealer on an agreed upon service date and do not receive the free remedy within a reasonable time should contact audi at 1-800-822-2834.

Visibility:windshield wiper/washerJun 18, 2001 · NHTSA campaign 01V202000 · 2,837 vehicles

Problem: Vehicle description: passenger vehicles (allroad). When activating the windshield wiper under heavy load conditions such as freezing, snow or heavy rain, one wiper could be delayed behind the other wiper.

Risk: If that happens, the wiper blades, because they overlap wiping areas, could become entangled with each other and cease functioning. This could impair the driver's visibility.

Fix: Dealers will replace the entire driver side wiper arm. Owner notification began june 22, 2001. Owners who take their vehicles to an authorized dealer on an agreed upon service date and do not receive the free remedy within a reasonable time should contact audi at 1-866-892-2834.

Fuel system, gasoline:storage:tank assemblyMay 3, 2001 · NHTSA campaign 01V157000 · 70,000 vehicles

Problem: Vehicle description: passenger vehicles. Sulfur in fuel interacts with certain additives found in widely available gasoline causing sulfur to become deposited on the contact points of three fuel sending units mounted inside the fuel tank. This could cause the fuel gauge to read full while the fuel tank may not in fact be full or could be empty.

Risk: Running out of fuel without warning while the fuel gauge indicates that there is sufficient fuel in the tank lead to safety problems.

Fix: Dealers will remove the existing fuel level sending units and replace them with fuel level sending units using a new alloy composed of gold, silver, and a small amount of nickel, which will not chemically react with sulfur. Vw/audi will also call back vehicles that were repaired under a previous recall last june in order to install the updated fuel sending units nhtsa 00v137/audi lb). Owner notification began may 1, 2001. Owners who take their vehicles to an authorized dealer on an agreed upon service date and do not receive the free remedy within a reasonable time should contact audi at 1-866-892-2834.
