Thanks for the advice, that will be my next attempt at curing the beat. I have just read this thread from the begining and the boost diaphragm sounds a very plausable answer. It is only when I put the car under hard excelleration and only when hot, that limp mode attacks. ie When the turbo boosts most. Now I know old style injection system used to have a diaphragm that increased the fuel mechanically in the pump when the turbo came on boost. But is this true of common rail? I thought this was all controlled by pressure sensors and the ecu? Does anyone have the definative answer..??? If it is a diaphragm..... Does anyone know where to find it as I would have expected a small rubber tube going to the pump somewhere. But I can't see one on mine. Having said that I can't see much on mine under the grime anywho..!!!
