Freelander TD4 fault, help

[armpower]

Thank to all.
This car have two fuel pumps.Some times ago i've replaced the two fuel pumps and filter.
I've replaced a couple of months ago also Mass air sensor.
When the fuel pump error go mad, usually there is a specific dtc, regarding fuel pressure too low.This is not the case.
By the way my dtc is undocumeted P1470.
Now i've re-checked all the hoses, also pneumatic hoses (egr and
turbo variable geometry control solenoid).
I'm focused mainly in a fault in this area (egr and pressure geometry control solenoid).
I'm not be able to repeat the fault just to check what happens.
Customer told me, when he drove the TD4 on the highway the fault appears.The cars slow down and go in limp mode.Dtc 1470.
In the last weeks also (he told me) develope black smoke during cold start.
Monday i'll replace the pressure geometry control solenoid and re-test the car.
Thank you very much for your help guys.

Hallo friends

Thank you for your support.
I've replaced the VGT solenoid, Land Rover Part. STC4198.
Now the car works well without any other error.
So the correct route (i think) to detect DTC P1470 is:
Check all vacumm hoses to egr and vgt solenoid.
Check the integrity of vacumm accumulator near the engine.
The turbo' variable geometry must move free without any assle.
The vgt pneumatic actuator must be work.
Check the pressure sensor on the mainfold.
Check egr and vgt solenoid with a vacumm pump and check with a scope the presence of main signal from ecu to solenoids.
Hope this help.

Bye bye
