Car ran hot while driving on motorway due to the water pump seizing. The temperature warning came on and I pulled over and shut the engine off immediately. I inspected the engine a saw nothing obviously wrong so I restarted the car and proceeded since the temperature indication had returned to normal. About 2 minutes in the temperature increased rapidly with the temperature warning returning. I pulled over again, shut the car off and did as before. On restarting this time the engine ran terribly and shut off after maybe 30 meters of travel. Now it will not start. No CID Faults shown.
