While you are under the hood take 5 minutes and tighten the clamps on the air intake hoses to the turbo to the intercooler and back to the intake.

My 04 threw a code early this summer and it was for low boost pressure and a little research told me to check the clamps. I was amazed and how loose they were. I tightened them up and no more code. This only set off a code and not limp mode.
