Thanks everyone, your code is the same as request on dealer by VIN. However I'm not being able to renew or even insert code in bench. I will see if I can test on car.

Also, do you know if changing those bytes is enough to accept a different code?

"Also, do you know if changing those bytes is enough to accept a different code?"
What is the point of these actions? If you reset this ECU, you can write any code there.
If the PIN code changes, both the key crypt and the ECU synchronization crypt will change.
If you change the pin manually, I cannot imagine what consequences this will lead to.
