OM 651 turbo removal.

Hello everyone!
Coming to ask for help, so my dads w212 is in need for removing the turbo, so far i have taken almost everything off, but the turbo is still not coming out. I unscrewed all the visible bolts from the top, but im wondering about the location of hidden bolts I need to remove the turbo. I have already unscrewed the turbo from exhaust manifold and dpf filter.
Also, dont mind the ground down exhaust manifold bolt, someone had already attempted to remove it and managed to strip the head so i had to grind it down.

I made some good progress on this task today.... 2009 C250 CDI... interestingly I found that removing the right hand wing, inner, top panel above the radiator, headlight and the front two vacuum actuators makes things a lot easier, then you can remove the cast alloy turbo pipe that connects the two compressors together and have lots of holes to pass your hands through. Then getting to the alternator bolts is super simple. For anyone reading this and wondering why remove the alternator, this is the only way to get to the oil return pipe under the turbo. Tomorrow I will unbolt the turbo, remove the exhaust manifold and oil lines and it should come out nice and easy. What i have done is not the official way, but in my opinion it has made the job 100% easier, but it is still a massive work up of a job.

Prihadi posted a good video. I saw another one on someone removing it in there garage/backyard and he was very shall we say not happy with stupid german over engineering. Needless to say he was feeling your pain.

Why your father is in need for removing the turbo?
