white smoke/black smoke does sound like a fuel delivery issue. (I agree with maurice mynah) - I would double check your fuel filter and make sure its a genuine volvo one.

I had no end of issues with my engine and after a long time found out my in tank fuel pump was failing, the clue was the fuel filter was out of shape (vacuum). A sticky vaned turbo is a good shout too.

As you are after suggestions, I just thought I would throw it in the mix for your consideration, its not a diagnosis.
