Well title says it all, I have searched everywhere but still cannot seem to find a complete list with how to's for this car. Maybe I just missed it but who knows, all I know is that this A8 is much different to mod. All these how to's using long code helpers do not work for we do not have this feature. If anyone has some how to's or a list of mods that work with A8 D3's it would be appreciated!
