Good evening all
i am trying to code a 2009 audi a5 with immobiliser5 with a new ignition key
what i usually do is use the new key to start the car and then this logs a fault for me to work with. but on this car when you try to use the key the car remains off.
i do have odis with the online functions but i have searched everywhere for "coding key" but cant find it anywhere.
i would dearly love a "dummys" guide to coding a key to this type of car if possible please. thank you for reading this and any help would be appreciated
