    Sounds like immobiliser kicking in... does a key shaped light flash up on the dash?

    Could be that the battery just needs changing on the key... a scan with VCDS would show an engine start blocked by immobiliser fault code typically if the immo was kicking in

    Tufty, changing the battery on the key wont affect the immobiliser as the chip in the key relating to the immo doesnt use any battery power, it is energised by the ring in the steering column.

    The battery in the key is purely for the remote function for the central locking. :)

    The most common cause is going to be your battery!

    Ill say again folks ..... the battery in the key does not have anything to do with your immobiliser ! you could remove it comepletely and the car will still start off the key ! All the battery is for is the remote central locking.
