Hi, I drove my 04 Mercedes E320 CDI through a small river accross the road which was about 12 inches high. It came up to about 2 inches below the body of the car. I was doing about 5 miles per hour and as soon as I hit the water the display said 'Battery Protection' and the car turned off and although there was some power there was not enough to start the car up again. My insurance company have said the car is a total loss but i could buy it back and I wondered whether it would be a good idea to do this? Maybe the water did not go into the air intake valve? What are your thoughts please?
