    Hi all,

    I'm new here so I hope that I'm doing everything right!

    I have a 1.2, 04 plate Corsa Design, and my Mum has a 04 plate Corsa Life, also 1.2 (I'm assuming that apart from appearance/extras there isnt any major mechanical differences)

    Anyhow on with the problem I was driving my Mums car earlier today and after a short break in the journey completely out of the blue the car wouldnt start. The warning light was flashing that indicates a problem with the immobiliser. After a number of attempts the lamp stopped flashing, the engine started and we completed the journey sucessfully. Once we got home I invertigated further into the problem, and found once again that the car wouldnt start. I found no difference between the main, and spare keys, with both having the same problem. Again after a number of attemps at starting the engine, with a combination of the keys the lamp stopped flashing and the engine started. I also had on a couple of occasions the engine start, then cut out about 1 second later, followed by the warning light flashing.

    Does anyone have any experience with such a problem? It sounds like one confused ECU/Immobiliser to me. :shame:

    Does sound like a faulty immobiliser module alhough you keep your fingers crossed & take the steering cowling apart to check the transponer ring around the ignition barrel has come loose & I don't know if the box is still there just beneath the ring (I know it was for the Cavs) & check the connections on that haven't come loose.
    Other than that I'd say back to stealer as should be covered by warranty I'd of thought.

    Hi and welcome!
    Try this, courtesy of MarksDTM.

    "First off, get in the car, shut the door, put the key in the ignition and turn until the battery/oil lights come on on the dash.

    Press and hold either the lock or unlock button, the door locks should Lock and then unlock.

    This will re-sync the rolling code in the key with the immobiliser"

    Cheers Hillper,

    I will try that one, but how does that work with the spare key? cos the problem is apparent with both keys. The spare is just a plastic fob housing the transponder, no remote buttons to press!!

    Hmm...in that case, you may have an immobilser problem.
    You may have to go to the dealer I'm afraid.

    Hmm, I thought that would be the case, I'm holding out for the loose connection, but I'm sure vauxhall will give me an answer.
