Bear in mind some hose splits are really hard to find, as you can't easily see them when not under boost pressure. If it is a leak, it will be very small, as you haven't got under boost limp mode yet.
Look for slight oil stains on the hoses, joints and intercooler. The intercooler should be straight edged, if it's bowed like a banana, it's had it. Also, all the metal C clip hose connectors should be really tight with no movement, any wobble in these, and they've had it.
