    Hi guys
    I’ve realised the knocking noise between rpm’s is not from the engine
    Its coming from the drivers front side
    I thought it was a drive shaft it’s a loud knocking
    The sound is only there when I drive the car in gear if I dip the clutch or neutral the car the noise will disappear
    Any ideas ???

    I'm sure it's not the first time, and definitely won't be the last, when symptoms are misleading.
    Might I respectfully suggest you start another thread.
    Adding a different topic, to the same thread, makes tracking specific issues harder.
    Regards

    For the knocking or pinking: Anti knock signals can also upset mixture and warm up time. A first check of all vacuum lines in pristine condition, re-torqueing all anti-knock sensors to ensure good sensing, and checks for nearby mechanical rattles not causing spurious knock signals around the block.
    Lastly the onboard black box relies on good earthing, wiring and continuity, so check all grounding connections are cleanly grounded and integrity of connectors,
    Incorrect knock signals can cause timing issues and incorrect fuel mixtures too, as do a lot of other sensors around the the complete engine/exhaust train.
    I really doubt you will find knock sensor on 1.6 tdi or in fact any other modern diesel.

    Vile Invention

    Dark was that day when Diesel conceived his grim engine that begot you, vile invention, more vicious, more criminal than the camera even, metallic monstrosity, bale and bane of our culture, chief woe of our Commonweal. How dare the Law prohibit hashish and heroin yet license your use, who inflate all weak inferior egos? Their addicts only do harm to their own lives: you poison the lungs of the innocent, your din dithers the peaceful, and on choked roads hundreds must daily die by chance-medley. Nimble technicians, surely you should hang your heads in shame. Your wit works mighty wonders, has landed men on the Moon, replaced brains by computers, and can smithy a "smart" bomb. It is a crying scandal that you cannot take the time or be bothered to build us, what sanity knows we need, an odorless and noiseless staid little electric brougham.

    Faults may have arrived after a system flush? Any diesel mechanic worth his salt would do that first.
