    I have an L registered Disco 2.0 MPI. The battery went flat and now it appears to be immobilised. I have recharged the battery and there is no fuel getting through and no spark at the plugs.

    I have tried the alarm reset procedure to no avail.

    I assume I need to reset the immobiliser but I dont have a clue how to do it??

    Where can I get the code and prcedure for my model of vehicle?

    Any help much appreciated!!

    Early single fobs are user programable a procudure that must be completed in around seven/eight seconds so that may be required (info has been posted before in the forum).
    If u have a two button fob then resync will be required buy pressing the lock button four times.

    Tried the programmable procudure but to be honest the fob has never worked since I got the car (about 1 year ago). Its a one button fob by the way.

    Pretty convinced its the immobiliser since it was fine before the battery died.

    Is there any way to bypass?

    U don't have an immobiliser as the 300 series does so if you believe you have a problem then try a replacement alarm/cl ecu located the the left of the glovebox it has a antenna plug on the side of it.
    You could get a replacement fob then you could have back the remote central locking and alarm.
    Yes they can be bypassed but as it's a diesel I can't help with that, again info can be found in the forum.

    Thanks.

    I will have to try a new fob as I believe this is the only way to reset the immobiliser. I wouldnt have thought it would be a faulty ECU, as it was fine before the battery went flat, but I could be wrong.

    The starter spins fine but there is no spark and no fuel getting through.

    Next one will be a diesel but I have to get this one back running first!! Pretty sure it will be related to the alarm / immobiliser but I could be wrong. Zero spark and zero fuel would seem to confirm its the immobiliser.
