J'ai téléchargé v dash mais je n'arrive pas a me connecter.
Le site paraissait hors connexion. Je rentre mon mail mais pour le mot de passe je n'ai pas de case pour le rentrer.
Merci de votre aide encore une fois

@Mustapha Than take a look at the manual which can be found here https://www.volvocars.com/fr/support/car/v50/10w46/

If you just want to change the language, you just need the adapter I posted, and a charger. No time consuming pin cracking required. If you are lucky, it is even possible for free, but usually it will cost a small fee.
And don't even think about programming your car without a charger attached. The V50 is really sensitive to undervoltage and will turn into a giant paper weight, when the battery voltage is getting too low.
