    Seems pretty self-explanatory. Your ECU thought the pressure in the engine's fuel rail was too low.

    You can confirm when this happens by checking these measuring values:
    IDE00188-ENG102817 -- Fuel high pressure: actual value
    IDE00201-ENG102664 -- High fuel pressure: specified value

    These may also be interesting:
    IDE01378-ENG100595 -- High fuel pressure: control deviation

    In the end though, there's probably some mechanical reason for this that will have to be found the old-fashioned way.

    The engineering problems are likely insurmountable. It would be like proposing to land a rocket booster section on a barge floating in the middle of the ocean.

    Has it recently had a fuel filter or been missfuelled with petrol?

    If the fuel filter has been chnaged and then the car started up without thoroughly purging the system using output tests then it is likely the pump is damaged internally, look closely for shiny particles inside the filter. If this the case, these particles can also get into the injectors and cannot cleaned out so you end up with new filter, new high pressure fuel pump, four new injectors injectors and cam belt kit with water pump plus having to clean out the entire fuel system to make sure no particles are left in there. Basically this just about writes the car off.
