Hi
I have a Range Rover Sport 2017 and it won't start. Dash is blank, start button won't work and no power to dash. Boot won't open automatically. Doors and alarm work but nothing else. Battery tested and its fine and fully charged.
Parked the car up one morning okay next morning nothing,won't start as per above.

JLR have the car and don't know what it is. Anyone had this issue before and could point in the right direction?

With that I would try a hard reset. Disconnect the 2 battery terminals and touch them together for about 45 seconds. Resets the computers, It sounds like the BCM had a hi-cup

 

Thanks for your reply. Would disconnecting the BCM for a few minutes do the same thing? I had that disconnected from behind the glove box and that didn't resolve it?
