This Update will be visible in Elsa and ServiceNet on or about November 22, 2016.
Please refer to the Elsa campaign/action screen for confirmation of whether the Update
applies to each specific vehicle. Additionally, this Update is posted on Elsa and
ServiceNet for additional information and complete repair instructions.
Consistent with general Audi corporate policy governing Updates, Audi is not notifying
consumers. (Updates differ from recalls and service actions; consumers are notified in
writing of recalls and service actions.) Each vehicle should be completed when it is in to
the dealer for maintenance or any other service visit. Dealer stock vehicles cannot,
however, be delivered to consumers until the Update is completed.
To identify any vehicles in your inventory that are affected by this Update, please run
the “New and CPO Inventory Open Campaign/Action Listing” report from the OMD Web
system.
Dealers must ensure that every affected vehicle gets the update before delivery to
consumers. Your effort is integral in reaching the highest quality expectations of Audi
customers.
Thank you for your cooperation and assistance in this important matter.
