What i did'nt mention was that over say the last month its taken 3-4 turns for it to start when the engines warm, Normally starts 1st click of the key be it hot or cold.

I changed the EGR valve last week as my revs were staying up when i dipped the clutch to change gear & its been fine.

I tried unplugging the EGR but no joy, Ive also fitted a new Crank Position sensor as they are always going on these.

Going to try the Glow plug relay tomorrow as i have a spare & go from there.
