  • J'ai mis 11l de gaz oil dans mon réservoir essence, est depuis j'ai l'indicateur de consommation qui a doublé, je viens de refaire le plein d'essence après 200 klms et j'ai mis 55 litres. Je pense peut etre un problème d'injecteurs gras qui restent ouvert. Quelqu'un a t'il fait la même erreur que moi?
