    If the immobiliser light is flashing, there's a fault with either the key, the immo box or most likely the igniton coil reader & wiring.. Give the little 2 pin plug in the coil reader a wiggle when you try to start it..

    Where abouts are you?
    I have tools to check the immo system, and also to over ride it.

    Does the car start then cut out?

    Does he have 2 keys? If he does he should try the other one.

    This, very occasionally happens to mine. I find taking the key out and putting it in the other way seems to stop it cutting out.
    This also works with the DAF trucks at my work

    I have an intermittent fault on the b5.5 passat. Occasionally won't accept one key but then is ok after being started with the other one.
