    Default Z19DT OP-COM readout

    Hi.
    Hope someone here can help.
    I have the problem that my Z19DT judder/misfire, especially doing the regen. I therefore tried to record data with op-com, and there is something that seems a little strange, the value of the Rail Pressure Control Solenoid Valve, is zero in both % and current, does anyone know if this is a normal?

    Regards

    As long as it is legit, which I would assume it is otherwise he wouldn't of asked the question after reading the T&C's. Op-Com is the european name of Vaux-Com, it is questionable when it is a UK member asking for help with Op-Com. Although I am sure a Mod will be along soon to raise any concerns.

    In relation to the question there is a ECU update available which cures the hesitation/juddering available from your dealer on the Z19DT engine, if this hasn't been carried out it may be worth a shot. But take note if they don't do it correctly, it can crash the ECU. Check out this thread

    If it was a legit Opcom he would be on ilexa forums asking for support, some may ask why we delete and close so many threads regarding Opcom ? Reason is just that there have been loads of threads started asking for support or just general questions !

    Plus the fact they are copies and can do a lot of damage

    Sorry but thread closed
