    ERROR codes!!! help needed

    hi guys
    car came back from garage today with 3 error codes been flagged up on the diagnostic machine.

    Astra diesel
    engine type X17DTL


    000100 AIR FLOW SENSOR CIRCUIT

    010500 CONSISTENCY BETWEEN ENGINE SPEED, INJECTED FUEL AND VECHICLE SPEED

    020400 EXHAUST GAS RECYCLING INSUFFICIENT FLOW

    can someone explain what these mean in simple English, and more importantly what i need to do to fix the errors


    Ive just changed the EGR solenoid, it was only a 2nd hand one, its got 1 month guarantee with it, I'm guessing the error 020400 is still referring to the EGR??? possible have a faulty ERG maybe........

    all help would be gratefully welcome

    thanks Mark

    000100 sounds like a mass air flow sensor, check the wiring and if possible borrow one from someone with the same car/engine.

    If you've replaced egr already then it will take some time for the codes to clear (iirc 20 starts without the fault).

    Sorry can't help with 010500

    cheers Shahid
    i change the EGR solenoid, without realizing theres also a EGR valve that gets clogged with sooty deposits.
    was going to clean this out with some carb cleaner, but i can seem to find it Ive followed the Haynes manual, but it only states, remove air filter box, and ducting to turbo...... then it goes straight into 'remove pipe from EGR valve'
    YEAH RIGHT OK, but where is it
