    Default Known software updates / field remedies

    As the title suggests, I am hoping to compile a list of the above remedies and software updates known for the 3.0 so that I can beat the dealer about the head with them and get them done! All help greatfully received!

    The main ones relating to poor running are 1957 (SCV's on fuel pump) - dealer needs Tech2 to compare actual and desired fuel rail pressures.

    1831 - update of ECU software to reduce "whooshing" of EGR.

    There's a couple relating to oil pressure switch (1966) and oil pressure warning (1841), 1887 relates to blocked air vent/ breather on ECU box, 1740 (engine stalls during drive off and/or A/C compressor shut off at high loads).

    I regret having mine updated to software v.10. It ruined throttle response in neutral and holds on to the revs longer inbetween gear changes.

    That thing seems to just send a signal that the pedal is further down than it is? Wouldn't a tuning box or remap be better for that price?

    I had 2226 applied to my Z30DT a number of years ago, ,it would tickover and then shudder & judder similar to 'hunting' throw a car/spanner warning light with an error code P0301 (Cylinder miss-fire) - something to do with Small Quantity Learning - had it applied, it did make the throttle pick up slightly more sensitive on gear changes but you easily adjust to that but fixed the problem, never re-occurred since.

    Hmm. Mine has being doing the shudder and judder bit for about a month now but only when the engine is at running temp and for example sat at traffic lights but it does not throw up the spanner light. Plugged code reader in and nothing was found.
