    Hi guys has any one ever has their HPFP fail or on the way out on a 1.6 TDi ???
    After watching a video on YouTube if the HPFP is in the way out you would find small metal fragments in the fuel filter which are pushed around the fuel lines.
    They also cause block ups in the injectors and cause a misfire.
    Upon inspecting the fuel filter I did find small metal fragments in there

    Hi guys

    I got my car back last night after being in the garage for 10 days.
    iv had my original injectors tested which came back fine with no faults.
    on the vag computer fault in injector 2 was keeping coming up so I replaced injector 2 with a used 53k Miles injector.
    iv also replaced the High Presure Fuel Pump from a running car.
    But the knocking & low rev missing still there.
    once the car is warm the misfire goes away but the knocking at 1000 rpm is still there ??

    First let me declare that I KNOW NOTHING ABOUT DIESELS and very little about anything else .
    However, I've been following this thread with interest and, unless I've missed a post, although injectors have been checked both electrically and physically, there's been no mention of checking the ECU. My limited knowledge only extends to the ECU being responsible for controlling the amount and timing of each injector's fuel delivery.
    Not sure if this relevant, someone will probably object, but I'm just reaching for an understanding.
    Hope this link helps

    I get a lot of CAYC engines running badly, if it has had the emission recal done, it would make sense to get someone with ODIS to check it out and make sure there are no further software revisions and there is also a smooth running setting which I have used to good effect BUT still we often have to fit four new injectors and a new pump. Was the second hand injector coded in? It also pays to have all the IMA coding values checked, on a few occasions I have seen cars with the wrong value entered on one or two injectors.

    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.
