I have a 2009 Land Rover discovery 6cyl petrol, So this afternoon all the lights on my dash were flashing and beeping. All different warnings started coming up on dash like limited gears available, height adjustment unavailable etc was prob 10 diff warnings, then my radio turned off and back on. Then off again and dash went dead no lights no screen and guages were dead. Made a clicking sound within the dash then the whole car shut off. I rolled to the side of the road and does nothing when I try to turn it over, key doesn't do anything to try to lock or unlock and even the hazard lights don't work it is completely dead. Any ideas what could've happened or could be wrong? Thanks
