Q5 Black Edition
Have today with friend who has Obdeleven Pro, been trying to make changes to Freeway Flash, changing from 3 to 5, needle sweep etc, tried to change thing by long coding or by use of an app available through Obdeleven, but car will not accept any of the changes attempted.
Has anyone succeeded and if so what adaptations or got any suggestions as to why the car will not accept changes.
