On the way home from work tonight my 07 MCS threw an engine malfunction code. The code is CC-ID 0 31. The car also does not have as much power. It feels like the turbo is not kicking in. A few miles before the engine light came on I could hear a whoosh sound every time i pressed in the clutch as I was driving. I have never noticed this noise before. I have gotten this code before but the car has always run fine and it has eventually reset itself in a day or two. Any clue why I have a loss of power all of a sudden?
