Coding: Audi A8 (4E) Access/Start Authorization - Ross-Tech Wiki

Immo3: Immobilizer - Ross-Tech Wiki

You can do basic coding of it, but you won't be able to mate the keys to the vehicle.
Has to be done by Audi authorized repair center as it talks to the mothership in Germany.

 

Oh. So how could i code if ignition is off? Nothing happens when key in. Then i would have to tow to dealer? Thats not fun

 

Also what code do i use?

 

Not sure how you could without the ignition on unless you 'bench coded' it.


Suggest asking Ross-Tech directly since I'm not sure this is even possible without SVM and GeKo (dealer tools)
Jack frequents that forum often and no doubt will have an answer.
