Hello all BMW turbo specialists!

I have a problem on my 1980 M102, no boost at all.
On my boost gauge, I can read vaccum at idle, but only 0bars at full throttle.

I read a lot of topics here but not found any solutions

I have measured turbo play: axial play 0.05mm, and radial play 0.5mm, so it's correct.
The turbine turn correctly and wheels are in good conditions.

See pictures:






I have search for leaks and found a cracked hose (n11631273055) but no effect after new one installed.

I took the compressions and they are good (9, 8.5, 9, 8.75, 9 and 9)

The ignition timing is correct (12 at idle and 34 at 2000rpm).

I don't know where to look, does anyone have an idea?

thank you very much
