    I have removed plugs from my 2003 330d. Is there any way of testing them out of the engine

    With a simple multimeter measuring resistance across the terminal at the top and the body of the plug, a working one have very resistance 2-3 ohms and a duff one is open circuit (cheap multimeters will read it as very high resistance)

    Failing uses a battery and light bulb, the bulb should light up across a working plug

    or get a bit of wire and a battery. Wrap the wire round where the plug would go on the top, then hold the threads on the negative and see if it glows! Would advise holding with pliers tho

    Forgot to say the wire thats wrapped round needs to be touched to the positive terminal

    So there is infinite resistance / open circuit on them all?

    The can go one by one, and not be noticed if the weather isn't too cold.

    No what happened is the bendix on the starter motor was giving trouble and you had to repeatedly engage the starter motor for the bendix to engage and turn the engine.
    After a couple of months of this the car would no longer start even though the starter motor was turning the engine.
    Had the plugs checked and all were found to be absolutely dead.
