    Wow, I only learned of the Photbucket thing today. What B@stards!

    I've literally hundreds of photo's, going back years, linked to multiple forums in the form of guides, project topics etc & now they're all FUBAR!

    Well done to Simon for rescuing this one though!

    Thank you so much for taking the time to write this how to, it was really straight forward and has helped me so much!!!

    One thing I did was I replaced the bolt on the DPF clamp with a longer one it made getting the clamp on extremely easy... Also I rotated the clamp so that I could see the top of the new bolt through the bottom left hand hole in the air filter box.... I could then get access to the nut and tighten it really easily without the tricky removal extensions and universl joint at a weird angle

    Thanks again so much for this, it was such a good thing you did for us

    Hello fellow forum members:

    After completing a turbo swap on my 2007 320D recently (M47N2 of course), I'd like to post a few thoughts of the process while my memory is still fresh.

    1. When refitting the oil feed pipe and oil return pipe, use NEW bolts (the 2 bolts on the return pipe, and the 1 bolt that goes into the engine block). All three bolts on mine were visibly stretched, the threads were uneven in width. Fortunately, I caught the mistake and ordered a few new ones. I did not replace the Banjo bolt, as it is hard to find and mine looked fine.

    2. Take out the power-steering pump will make the job a whole lot easier!! Remove the stretch belt, 3 bolts on the pulley, 3 more securing the pump itself. Lots of access room afterwards. No need to disconnect the lines, just set it aside after unbolting it. Another post I found on the internet said to temporarily remove the turbo actuator, I didn't want to mess up the calibration, so removing the power-steering pump made the job possible. One note though, after fitting the turbo, the power-steering pump may be difficult to put back in. It does indeed go back in after bolting up the turbo, but you have to maneuver it a specific way, like a real f**ked up jigsaw puzzle... Not impossible though.

    3. After removal of the intercooler, I found my radiator drain bolt (made of plastic) broken, the head part had come off. Not sure if removing the intercooler caused that or it was from heat stress. Anyway, I was able to remove the rest of it and replaced it with a new item. If left undone, I would have leaked coolant everywhere. The bolt is only visible after intercooler removal.

    4. Fitting the turbo back to the exhaust manifold with a gasket in between is the hardest part of the job. It's really a 2 men job. I had only myself, so I stuck something below the turbo to hold it up into place. The old air filter is just about the right size.

    5. If you removed the metal "L shaped" bracket below the turbo, be sure to fit it back hand-tight BEFORE fitting the turbo, then fit the turbo, then tighten down the bracket after tightening the turbo to the manifold. I actually took the new turbo out just to re-fit the bracket, because getting screws onto the bracket after turbo installation is nearly impossible. I guess if I had some sort of snake-video assistance then it would be possible.

    That's all I can think of now. Car works fine after clearing the error codes. Hopefully this will help forum members in their quest to replace the turbo in the future.
