If the noise calms down, it's fuel system related and may be cured by occasional repeated use of 2 stroke.
If there's no difference, hydraulic lifters aren't out of the question.

If the results are favourable, you can be fairly casual with 2 stroke in a Euro 3 D5 but on a Euro 4, maybe only repeat every 5-10 tankfuls.

thanks for that, I have literally just put in a Redex injector cleaner, does that amount to the same thing or still do what you said?
