The garage put it the machine it came up with fault on the egr valve. It got changed for a new one, the light still stays on. I have also noticed a faint smell of diesel coming into the car as well on a long journey.

wonder if EGR pipework was checked and cleaned when new valve was fitted, also passageways in cylinder head ,they can carbon up if that is the case the new EGR will not work properly ,as for smell of diesel as previously said check for any leaks from pipes hoses and injector seals
