    Yes I have I think I will try and find it

    So having a -2.26 reading kinda says I have a faulty sensor ?

    I'm not sure. A negative number is certainly puzzling.

    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.

    This was my other post with a Auto scan there are zero faults also
    It is very strange as I would expect a fault code if it was fault sensor

    Iím not 100% what these readings are though is that what I should be expecting ?
    Cheers Matt
    Uwe did you see my reading when I checked the differential pressure readings

    Yes, I went back and saw them.

    What do you have in this measuring value?
    IDE00428 -- Particle filter: offset for differential press.

    Is this ECU mapped/chipped?

    Uwe the IDE00428 particle filter offset is 1hPa
    With just ignition on

    And the same at idle
