Supersedes Technical Service Bulletin Group 57 number 11-54 dated August 18, 2011. Audi advanced key (keyless entry) is inoperative on all doors, but the engine can be started with the keyless starting system (keyless go). The keyless starting system (keyless go) is a standard feature; Audi advanced key is an optional feature. All vehicles have an engine start-stop button (-E408-) and touch sensor surface on the outer door handles, but this does not mean that the optional Audi advanced key function is installed.
