Vacuum system leak ? (Anti shudder valve, EGR, Turbo vanes operated by a solenoids triggered brake vacuum system).

Does the engine shudder when turning off - Lift the bonnet and with the engine running observe the anti shudder valve to see if it moves as you turn the engine off (it should do).  This is visible at the top of the engine just under the plastic cover on the drivers side (RHD).

 

PS Smoke on cold start could be a faulty glow plug
