I'm afraid I can't help with that one, your Rangie is too new. I'm fine with 3.5's and 3.9's on hotwire injection but these newer motors are a bit of a mystery. Could be BECM, alarm/immobiliser, main ecu. Is there an inertia switch? might be worth looking at that. Other than that all I can suggest is you post in the Range Rover section and I'm sure somebody who knows how these things work can give you some pointers. Have tried doing a search?
