Thanks for all the replies. The Ford dealership said to me when I took my car in that they tried fixing another 2 litre diesel and the car would not start at all afterwards. They said to me that the new software disk currupted the engine management system on 2 litre diesels only. This got reported to Ford Technical who have told them to hold off reprogramming any 2 litre diesels until a new disk is sent. The latest I've heard now is early Feb.
