    2.5TDi?

    Its hard to tell what it is without hearing / seeing the engine - where are you located?

    I don't mean to frighten you / jump to conclusions, but a common issue with these engines is camshaft wear on engines with high mileage on the long life service intervals.

    A good place to start would be to open your oil filler cap and shine a torch in, there will be a camshaft lobe visible, see if it has any wear.
    If it does it will look like this;

    It's a 2.5 tdi Quattro I'm based in sheffield and I can't see much any more advise it can't be injectors it could be cam shaft but before I park it up it was fine soon as I start it so I could service it making a noise

    If you were closer I would have taken a look.

    Does it knock constantly, or just the first few seconds after starting?
