Vauxhall Astravan blowing grey smoke

I have a 2009 Vauxhall Astravan 1.7 diesel. In the past few weeks the vehicle has started developing a smoking issue, which no one can find an answer for. The smoke is grey in colour, but the van doesn’t use any water or oil. However, when you accelerate hard, it blows lots of smoke. The bumper is also black with soot. Any idea what could be causing this?

If it doesn't use any oil it's not turbo bearing oil seals. More likely worn injectors, which are the traditional reasons for diesel smoking dating back to the days before turbodiesels.
