Initial publication
Audi advanced key (keyless entry) is inoperative on all doors, but the engine can be started with the keyless
starting system (keyless go).
Technical Background
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 (Figure 1), but
this does not mean that the optional Audi advanced key
function is installed.
