I think you need to drop this yoke of to a good mechanic! Your head must melted.
E60 525d - turbo issue?

I think so? Awkward manoeuvring the manifold back in and under the cables but I thought it was ok.
I'll check egr tomorrow, thanks.
Anything else to check?

I'm in Bangor Comparing it may be extremely useful if you didn't mind at some point? In fact a drive in another would be great as I wonder did mine ever go as it should?!?
Last night there was virtually no power at all, never mind boost! But in recent times I would agree there has been little or no boost and the car appeared to be choking, for want of a better word? Not sure if that makes sense, but it's as if it was being held back. Some MAF issues thrown in there too I think - either caused by the real problem or masking it.
I took a punt on the leak being the manifold gaskets or breathers. Really only leaves rocker cover in that area - a bit trickier I guess!
Going to spend some time tomorrow with it, weather permitting. I'll get the under tray off as well and have a good hoke about, once I get rid of the sooty deposit covering everything
Trying to get hold of the fella that did the gutting last year too as he can confirm if anything I may find is actually an issue or now 'defunct' as a result of his tinkering. And he refurbished the turbo at the same time which may be worth discussing too.

Had a look under the bonnet and took off the engine cover. Not sure if you can make it out from the photos but quite a hefty layer of dust over everything. Bad underneath the cover too which might suggest the source is somewhere covered by it perhaps??

That's exhaust gases covering the engine.
EGR pipe broken, cracked manifold (very common), blown gasket etc.
All of those would explain lack of boost too as a loss of exhaust gases means they are escaping before getting to drive the turbine wheel.

If it's gases, should it be visible when engine running perhaps? Might help to pinpoint the source.
Haven't noticed any smell inside sometimes associated with cracked manifold, but how to check it please?
EGR area to be checked tomorrow.

Would usually be visible with a light, best checked when it's dark outside. Either that, or get someone to cover the tailpipe for approx 1 second at a time to see if anythings apprently.
You'll be best getting it up to running temp before checking.

Just saw a vid on the tube - was an E39 but probably the same idea. So basically I should get smoke/exhaust in the engine bay when running? And hopefully if I can see roughly where it's coming from we could perhaps identify the culprit?

Lol!!
Depending on what happens, might need to pick your brains about what's involved in the Egr delete too, so I know what's what when I'm checking. I'm sure there is at least one plug and pipe disconnected as part of the process.
Offer nicky 50 quid to visit for a few hours of his time to give it a check is what makes sense to me.

Well, went out tonight to give it a clean - horrible!
Anyway, found a split on the underside of the pipe leading to the egr
I'm hoping that explains the soot but why did it split? Or more importantly, was it weak and starting to split through wear and tear, or did something else cause it?
I'm guessing a split pipe wouldn't cause all the issues I've been having tbh
Also, there is a metal band securing the pipe top and bottom, but they're not jubilee clips as far as I can see. Anyone know how to remove them?

Replaced Egr pipe today with new (silicone) one. Seems much better!
Found another slight 'blow' though - this little bugger
it's the clip to join the Egr. It's like one of those grooved, exhaust type clamps. I remember it being awkward when I replaced the manifold but thought it was sorted. Obviously not! It's a pig though!
