Stephanie: I think it is not the FMU itself but the check valve that is making this noise. But currently I have bigger problems as you may read above.
I picked up the car to tow it to it's home just an hour ago and we tried and managed to start using throttle application. Engine seems fine at this stage, the turbo however makes alien metallic noises. I will upload videos I captured to YouTube and post them here for your diagnoistic expertise (or banter).
Stephanie: will e-mail you the YouTube links.

Normally an intercooler hose blew off the car dies and you cannot start it.
The airflow meter measures no air... So the engine wo'nt start.
At 5.5psi i doubt any engine failure.

In my manual it says:
Check the “atmo” fuel pressure: With the fuel pressure gauge installed in the fuel line leading to the fuel rail,
observe the fuel pressure at idle. It should be between 35 and 38 psi. Blip the throttle a bit and the fuel pressure
should rise and fall a couple psi.
Im around 5.5psi now. So my idle is ok..
BTW, found the coolant leak: where one of the heater hoses connects to the metal pipe that goes below the manifold.

The 5.5psi boost x 6 psi/psi= 33psi.
The fuelpressure should be (setpoint, around 45) 45+33=79 psi.

Ist things first. CHECK ALL PIPING beween airflow meter and turbo.
Even with a deffect turbo the car runs (idles) like stock.
Not crappy like this...
All 100%???
Can you remove the heatshield from the intake??
Remove the intake and feel the shaft off the turbo.
Does it rotate freely?? No play over 1mm???

Well, the compressor side has been opened up now. Picture and video:
(Video is still processing, so it will take a few minutes)
There is virtually no play on the compressor wheel, certainly less than 1mm.

Ok so the turbo looks ok bij feeling.
The audible metal moise is coming from the turbo???
Still feels like something is in the way off the turbo blades....Could be exhaust or intake...
Remove the turbo and check if something is in there. Check the manifold too.
I know it is a lot off work (and hot today)
Strange that the car is running so bad...I think you still have a vacuum /boost leak.
You can try to pull sparkplugs when idle. 1 at a time or youll be fried too..
Iff 1 off these plugs have no effect (dropping idle) report back.

so you know your fuel pump can make 80psi in the rail. did you have 80psi when you were boosting?
It sounds like you adjusted the preload correctly. This meaning that the FMU, once it sees boost, is ready to up the pressure from 50psi it was set to. But did you adjust the needle valve to set the rail pressure while in boost?
where is the metallic pinging noise in the videos coming from?

The axle from the turbine site can be pulled out very very slightly (< 1mm) but I suppose that is normal too?
I will e-mail Stephanie to get BEGI to help me with diagnostics.

Noise is comming from the Turbo, or so it seems. But it's off now so I can't retest.
Since I have the oil and water feed + return loose now, I can't really test anything.
