I have a xc70 d5 2007. It had a rattle at the back end, my mechanic can't find it. I've been underneath and I have found movement in the diesel fill pipe that connects to the fill cap. Should it do this? I don't know if it should have some play for vibration or whether it should be completely static. Does anyone know how it should be? I've attached a video thanks.[YOUTUBE]
