Additionally, unless included in "Zone A" above, Volkswagen is recalling certain model year 2004-2008 Audi A4, and 2005-2008 Audi A6 vehicles originally sold, or ever registered, in Arizona, Arkansas, Delaware, District of Columbia, Illinois, Indiana, Kansas, Kentucky, Maryland, Missouri, Nebraska, Nevada, New Jersey, New Mexico, North Carolina, Ohio, Oklahoma, Pennsylvania, Tennessee, Virginia, and West Virginia, or "Zone B."

These vehicles are equipped with certain air bag inflators assembled as part of the passenger frontal air bag modules, and used as original equipment or replacement equipment. In the event of a crash necessitating deployment of the front air bags, these inflators may rupture due to propellant degradation occurring after long-term exposure to absolute humidity and temperature cycling.

Consequence

An inflator rupture may result in metal fragments striking the vehicle occupants resulting in serious injury or death.

Remedy

Audi will notify owners, and dealers will replace the passenger frontal air bag inflator, free of charge. Owner notification letters were mailed April 28, 2017. Owners may contact Audi customer service at 1-800-822-2834.
