My old disel isn't as fancy as your Jag :) but I had a problem like this and it was worse when the weather is cold. I found that 5 out of 6 of my glow plugs had gone. It also used to blow a huge belch of black smoke when it started. Once going it ran normally.
To test my glow plugs I just disconnected the wirre and checkd for continuity with a multi meter from the terminal to the engine block. If the connection is open the plug has blown. Mine glow plugs wern't much harder to change than a spark plug.
Hope this helps
Check into glow plugs, sounds like some are not working.
