    It is a common problem turbo vanes sticking and causing over boost ,Ive heard of some people take the turbo apart and clean it out with mr muscle, New turbo would be my option but im sure you can get it done cheaper than 2k!

    I think 0798ezza has made a mistake with the 00564, It is the p0234 fault code that has been mentioned above and i have that down as overboost so this is the problem that you need to be looking into . The problems you are having are recognised and the engine is cutting the power to protect it from excessive amounts of boost, and when you turn the engine off and on again , it will reset everything. I would get the turbo actuator system checked first for any problems, split hoses/ vacuum pipes, and get the turbo checked. I don;t think you egr valve will be causing your overboost problem. More than likely you have sticky turbo vanes like ive mentioned above
