I've got a new 2024 model a6 avant - it's one of the new totally locked down models - it can't be coded at all, no odb11, vcds, odis - nothing - it won't even accept an AI box. And has a speed nagging device fitted.
My question is if i replace the ecu with a 2023 ecu will this be able to be coded or is it not the ecu that controls these functions - if its not the ecu then what does control functions like, lane departure warning, speed nagging device, tail light animation and such like - any help would be appreciated
