hallo,

I have an Octavia III My 2015, it has the following optionals: line assist, front assist and cruise control. Do you think it is possible to active the ACC? do you know the code adaptation?

I dont know for sure but probably to enable ACC you will need an "activation code" which is only available from VW same like for standard cruise?

ACC uses a different stalk to set distance etc. and I'm not sure if the front radar is slightly different too. It's not a simple software activation, I too have those 3 options on my VRS.
