It is with turbo or not
if it has a turbo should be from the turbo, if it does not have turbo thing that is most likely, it is not of the Evap sensor, but of the electrovalve of the EGR system (recirculation of the exhaust of the exhaust) that is a pipe that leaves the multiple of exhaust towards the admission duct which has a mechanical valve that is controlled by that electrovalvula but that it does not necessarily go directly connected to that hose, but it carries Un tuyau métallique sur le couvercle de soupape, où il doit être connecté est une manguerite de l'électrovalvula ..
J'espère que vous posez toute question de demandes ...
