    pinking is usually associated with petrol engines mate!
    timing mainly, and trying to mentally picture what your describing is pretty difficult!
    from what your suggesting i am guessing its a metallic rattle noise rather than vibration at any revs other than tick over?
    is this correct?

    yes mate a metallic rattle like just like pinking but obviously its not with it being diesel just seams to be in the mid range of acceleration whilst driving in gear , it goes when you lift off the pedal or when you accelerate harder ?

    well i was going to suggest the oil pump/balance shaft problem associated with earlier models, but, thankfully in your case i dont think is the problem unless you have the dreaded chain driven oil pump which i am 99% certain you dont!
    this "pinking" is something else, and sadly cannot think what it is!
    i am sure somebody will be here to instruct/advise mate!
    sorry i could not be any good, but i dont want to just guess! as that would not be helping anybody!
    good luck fella!
    and let us know how you get on!
    knowledge is power as they say!
