    Well spent 5 hrs on it yesterday, and have come to the conclusion that the wastegate is knackered, you can wiggle the arm back and forth for so long then it sticks, that bad that you need a screw driver to prize it back open, i couldnt even get the bolts undone t look inside, as these went from a 10mm, to 9, to 8, to a circle, not fun.

    Built it all back up wnet for a drive an bang the oil feed pipe burst /snapped spraying the whole engines oil contents all over the engine bay, wha f***ing joy!!!

    Well after hours of Mr Muscle and a lot of pain in the arse, i have decided to get the turbo refurbed.
    The vanes had stuck that bad it was close to seizing, pretty lucky really as once it had been stripped the bearing was also on its way out.
    It is now with AC Turbos in Skelmersdale, £240 for a full refurb, lets hope this is it now.
    Thanks for all the advice guys will keep you informed,
    Cheers

    I had the EXACT symptoms on my golf tdi, just before replacing the turbo we flipped the check valve, turns out the factory sent out a bunch of tdi's with checkvalves backwards that year. Fixed the problem in two seconds!
