    take the bold off... we're not all blind? even though i wear goggles lol...

    before jumping at the dpf, do you have one & have you checked the swirl bar...

    what model do you drive?

    Sounds like it maybe doing a regen. Are you sure it wasn't carrying one out? (not trying to teach you to suck eggs here)
    Now I need a turbo to keep up!

    No, probably no light on. Are you sure you have a DPF? If its an estate or an auto it will have one, but if its not either of those, its probably not got one.

    Easiest way to tell is to check the instant consumption, if its like 1.6g/h then its on a regen, if its 0.1g/h then its not.
    Now I need a turbo to keep up!

    I doubt you have one then. There is a way of telling if you have one with a number on the data plate on the drivers B pillar but i cannot remember what - sorry

    you don't have dpf... you most likely have a serious boost leak, split pipework or intercooler... worst case fooooked turbo. that's assuming the swirl bar is in place
