Thank you for your reply,
You are bang on with the EGR valve, I ended up calling the RAC out on Sunday and straight away he said EGR valve so he plugged his laptop into the car ran a few tests and he said yep deffo the valve, so he put a blanking plate!! On it if I am correct in saying so and the car came back to life, The RAC mechanic basically said that if they had sorted it out in the first place the engine wouldn’t have clogged up and died saving the garage around£3000 and saving me allot of hassle. I ended up taking the car back down to Croydon on Monday and said if your mechanics has noticed it in the first place it would have cost less to replace the valve than to redo the engine.
So hopefully fingers crossed it will get sorted this time after the millionth time of going back and forth for the same problem.
Once again thank you
