Have you had a service done where the fuel filters were changed, if so check that they are in tight, need a 27mm socket and the bleed screw is tight....dont use gorilla grip its plastic.
Actually even if you haven't had a service I would start there and work my way up to the engine along the line looking for any weeps though an air leak may not show up as a fuel leak but fuel could be bleeding back...
You don't want it long cranking one bit as this can mean the HP pump may not be getting enough lubrication, try turning the key to ON with foot off the brake twice before booting the engine, this allows the pump to to bleed air out of the lines and it should start as normal..... if this works I would continue to do it until you get the problem sorted...... you don't want a HP pump failure.... a proper diesel shop like Diesel Care is a better place to start than a dealer in most cases.
