ok thanks but wouldnt a light come on my dash if it wiring cause i havent had one i have been talking to a diesel fitter and he said it could be my egr valve or actuator and do you know what the fault code po234 is as that has come up aswell
my engine starts great with no problem its while im driving i lose power i have the accellerator to the floor and it doesnt go over 80 and if i slow down it doesnt pull away very good its very sluggish but if i turn the engine off and on again it goes back to normal and its only intermitten

had the car in vw garage today and its the turbo vanes sticking is there anything i can use to clean the carbon of as vw want to peplace the turbo at around 2000 pound
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
Thanks yeah I did get code wrong had it in vw garage and yes I need a new turbo the turbo vanes are sticking thank you will the car be ok to drive for the time being
