I have not done it myself but this is how I understand it...
You have 2 levels. Your Renault ZE Online account and then the account for the car itself.
As I understand, anyone can create a Renault ZE Online account, it is just a matter of registering at https://www.services.renault-ze.com/user/login.
Once you have an account, you have to add the vehicle itself. And in order to do that you need the activation code that you got with the car which is connected to the car's VIN.
So the way I see it, you need to do this:
1. Log onto https://www.services.renault-ze.com/user/login and delete the vehicle.
2. Give the VIN and activation code to the new owner and let him add the car in his/her own Renault ZE Online acount
And let me know if I am wrong
