Hi Steve Q, Thank you for your reply. I have tried the app and it just tells me I have to pay to reinstate the function (Adaptive cruise control). The system has also reverted me to a guest user and removed me as a named user that the Audi dealer set me up with when I bought the car earlier this year.
I think I am going to have to pop into the main dealer nearest me. Do you think they would be of any help?
Kind regards
