If it was a turbo hose is it easily seen on top of the engine? I'm reasonably mechanical and if easy would try and replace it myself to save the hassle of towing it to the dealer. I am surprised it didn't throw a CEL... too tired to go screw with it tonight. Will call the dealer tomorrow and go from there. Luckily it's not my DD!
Just follow the tubes from the turbo to the aftercooler and back to the engine. The tubes should all be visible from the top.
