Pulled up at the shops today. When I came to restart, engine cut almost immediately, twice. Now it just churns over but won't start. Afetr reading through other topics, it sounds like a problem with the immobiliser. When I put the key in the ignition and switch on, the door led stays on and then starts flashing for about a minute, it then starts randomly flashing. I've tried reprogramming the key but it makes no difference. Anybody have any ideas or is it a tow to the local Fraud dealer?? :(
