Hi, Ive managed to loose one of the rubber balls in my headlight washer jet, when I took it in for servicing a few weeks ago, they said, it needed to be replaced, which I thought was right, but theyve called me back to say the parts come in and they need to fit it. I said I thought it was just the rubber ball but theyre saying they need to replace the whole washer jet. Is that right? has anyone else had Renault say the whole thing needs to be replaced?
