Hi all, first time on the forum but your assistance would be greatly appreciated.

We have a 2012 Discovery 4, the other morning I got in it to go to work and it wouldn’t start, the break was firmer than usual, slight tick when I pressed the button to start it, the red battery light was on the dash and a message on the screen saying the entertainment system would go off if the engine isn’t started due to low battery.

Since, I have changed the battery to a new one and had it on diagnostic which said an Immobilizer fault. At present it is on the drive stuck in park unable to be moved.

Thanks in advance, Daz
