D40 2.5 dci 126kw - I HAVE NO MORE IDEAS, turbo?

[Radas]

Hi all,

I have big problem with my Navara, but it has no solutions.. can you please help me?

My Niss has no power, acts as turbo is KO. I tryed to changed almost everything - turbo, intercoller, checked all hoses, EGR ok, exhaust OK.

I checked all the vacuum hoses, all the air lines, the complete exhaust system including the EGR, I replaced the turbo for the second time, tryed to replace motor unit - STILL NO POWER.

What next? Scrapyard? Thank you all for your answers.

partially blocked intake , if your car has electronic throttle body, flap could be stuck partially closed , remove the intake hose and check that its not swinging it should be either fully open when running or closed when engine off.. you can disconnect the loom to it and run the car. i have had both these problems
