Drove the car (2005 X-Type) all morning and parked it for 5 hours came back and I was unable to start my car. I was able to unlock it, all the lights turned on in the cabin, and all the displays turned on but when I went to start the car it would not turn over. No clicking or any noises came from motor, I'm worried because the mileage was not displayed it was just ----- all across. I called local dealership and the proposed it was a dead battery?
