VNT Adjustment - GTB2265V Turbo - Not holding boost

Hi All,


Hope all is well with everyone that reads this thread and is able to help me.


I drive a Seat Ibiza Cupra 1.9tdi (PD160).


I have recently upgrade the turbo to a GTB2265v from a F30 BMW 330d.


The car has been mapped. It is requesting 2bar (29psi).


I have checked all the vacuum lines and they are fine. I have also read the following thread 'VNT Actuator Adjustment - GTB Turbo on an '06 BRM"

I have tried to adjust the stop screw to the above recommendation on the thread of 100mar - 150mbar but i can't get that. If i remove the stop screw not much changes.


Any advice or help would be appreciated.


Kind Regards

More informed people than myself might be able to help. Can you post logs recorded with vcds? Then everyone can see what the turbo is doing after the ecu/map has told/requested it what to do.

Intake air temperatures cutting back the fueling/boost? You don't say which way you turned the actuator arm, but the second run looks as though it may be too short.
