Controls the Geometry of the turbo,The system turbocharger hoses etc
and generally an inconsistency on the turbo pressure...

[canotto2000]

Thanks five, I have already changed the hoses to the turbo with those of stainless steel, changed the valve adjustment turbine...
I know not what to check on.
With the delphi oscilloscope I measured the various curves, but no fault...

[amen]

test with the fuel filter, even if it has nothing to do, it happened to me, when it's not him, is the valve the turbine that you have already changed.

[canotto2000]

Thanks Amen, I try to change it and I'll tell you

[canotto2000]

Nothing to do, it always comes out the code p1470 and it is as if stallasse 140 and 150km/h

Then got a good diagnosis in real time and check how it works the turbine

[canotto2000]

Already done it Amen, everything is ok, the turbo pressure and rail are constant, when the go to the stall, it raises the graph of the rail but the turbine remains constant.

then would check the regulator and rail pressure sensor and rail pressure

Pressures reach?
between objective and measured and you have a variation?
