Hi and a warm welcome Davide.
Looks like a bit work needs to be done.
Your gearbox ECU is running in fault modus, so first you should read out the error codes.
The front brake discs are pretty expansive. The rear ones are cheaper. Mind the parking brake mechanism at the rear calipers. The levers must not jam in their housings. After releasing the handbrake the levers need to return to their rest position automatically.
Good luck with your new car!
