Thank you very much for all the information, it is most helpful to me to know what the possible cause is. I have owned the car for a year and never had any issues with it. I will check the oil level when I go to the garage later on. I last topped up the oil 4 weeks ago and have done approximately 400 miles since then so the oil level should be fine. The turbo was in use when the car died so I will let you know later on about the oil level, many thanks for your help.
