Hi Guys

Driving Friday night on motorway and suddenly got reduced performance triangle on dash. Car immediately dropped power but got nursed home. Lifted bonnet and revved engine, but 3inch pipe from intercooler was sucking in flat when revved. what can cause this? No smoke or anything and engine still sounds sweet. any help appreciated
