Why does my diesel car sound as though there is a bag of nails rattling around when I start it?

Why does my diesel car sound as though there is a bag of nails rattling around when I start it? It was never like this for the first 5 years. The car is a Citroen 2.2 HDI, is 10 years old and done 70k miles.

Because not all of the glow plugs have glowed so initially it is only firing on 3 cylinders. As soon as it gets hot then compression ignition means it will fire on all four.
