Year of Manufacture *: 2005

( Optional ) Scanner Used: VCDS
No fault codes are stored. I found 2 cracks in the fuel pipe so replaced those. It has a new filter, new injector seals, new t-piece on top of filter, a good used tandem pump has been tried. A one-way valve has been fitted near to tandem pump and this improves things but not a permanent fix. I have taken a pressure reading at tandem pump, does anyone have the specs for this and also low pressure too? The waveform for in-tank pump looks ok, plenty of fuel at filter when fault occurs. I am suspecting a crack in cyl head but there is no evidence of any mixing between oil, coolant and fuel. Still have ecu comms when fault occurs so main relay is ok.
Vehicle is now usable with the one-way valve but would rather do a correct repair, any ideas would be appreciated.
