i had a similar problem with mine, the radiator you're talking about is actually the inter cooler like the others have said. the pipe should be help in place with a clip of some sort, and not just wedged in.
becuase its part of the turbo system the pressure can get very high, so what seems secure to you, could easily blow off when you get full boost.
i'm not sure how easy that pipe is to inspect on the 130, but check to see if a clip has snapped gone missing or if the connector on the pipe is worn.
oh when it comes off, you have no power and lots of white smoke yeah?
good luck
