Got a scare after working on battery cables. Switch on but engine light/ECU , come on engine does not turn over. Immubilised After spending time on the net tried everything to no avail and the security code that I have is not the correct one. Where do get it? The dealer not helpful. Got hold of Martin at Salisbury Land Rover a few questions and said put the keys with remote on the steering between the ignition and gauges. Take of the positive cable arc it 4 times on the battery, you must hear it and start and it did!!!!!!!!!!. This is not the first time I worked on the battery and that in Moz.
