Thank you very much for the comprehensive explanation

@T5-T6-Schnappi Will all changes be reversed, including the change from miles to kilometers, for example, or will the light settings to European ones also be changed?

@T5-T6-Schnappi Thank you for the comprehensive information.
I live in Poland
I forgot something important. If you add a keyfob with VIDA, all changes made with vdash will be reverted.

Hi
Yes, it's keyless.
I bought two keys, a 433 (Google suggested) and a 913 (probram suggested), and neither worked.

Hi
Can someone explain to me the exact procedure for adding a new key to a 2015 Volvo XC70 P3 in Vdash?
I've tried several different methods, but nothing works.
