    i recon the turbo will come out the top if its anything like a 1.8T

    Basically its a case of remove the airbox and boost pipes, remove oil and water lines (you might have to remove them from the block rather than the turbo if access is tight) remove exhaust pipe, remove turbo.

    cheers boys,
    I'll be attempting this over the weekend should we have good dry weather.
    Sounds straight forward but i don't have a clue so will be a mission for me...

    hmmmm has anyone tried some form of water treatment for the engine. get it to ingest a supply of water at fast idle. the flash steam process should do a damn good job at cleaning it out (ie have you ever taken the head off a car with a head gasket failure?
