I have just remembered in the splitting or sucking jet pump pipework there is also somewhere a little check valve that sticks, mine had, IIRC and could be allowing the fuel levels to draw unevenly.

Evening. ....right..have had all the bits and bobs in the tank apart..all clean..no leaks.and the one way valve is working....had it running with the fault codes reader....now if I Diss connect the fuel rail preasure sensor the car will run and go in to limp mode.soon as it's connected the fuel preasure spikes and goes to max and stalls the car....indicating that the preasure sensor is at fault...it all so comes up on the code reader as rail preasure fault. ....will get a new valve and fit and go from there. But the rest of the fuel system is working correctly with the correct preasure...if the new sensor doesn't make a difference then it would point to the main preasure pump or valve at fault. ...

Can your code reader/software show you live data?

I'd be surprised if they had it on the shelf
, if they have to get it from Germany you can be looking at next Tues/Wed before it reaches them - hope I'm wrong though and you have it in you excited palm in the morning.
