I've spent the morning changing my water hoses and after burping the system and then going for a drive, my car now has a peculiar whine with the turbo and it's a little jerky. I haven't floored it to see what happens as I don't want to make it worse. I've found a pipe that's only attached at one end but no idea where it's meant to go. Hopefully this is the source of my problem and someone can tell me where it should go.
This is the passenger side down the side of the intercooler. The hose is the small rubber one on the right of the orange water hose.
