    Hi

    You'll probably find that it's just a little extra fuel from not having the DPF. The ECU has been told not to worry about the soot count or the pressure difference but no one has told it to back off the fuel.

    This is abit of a guess in your case as I have not see the smoke for myself.

    its always on idle and comes in waves its like a blue/white and smells like fuel rather than oil burning going to see the guy next week who mapped it and check if it is the map.
