The hose outlets should be coloured white and yellow the yellow goes to the EGR. the inlet on the top of your selenoid is an atmospheric inlet it allows the selenoid to measure atmospheric pressure,when the engine is started you may feel air being drawn into it .hope this helps.

Thank you!
seems vacuum hoses connected correctly.

2,8jtd turbocharger is variable geometry or not?
how should work turbocharger actuator? (2nd. foto)

have any ideas, why can be white-blue smoke?
it does not mater cold or warm engine.
oil and coolant doesn't missing.. engine start very easy and without bad noise..
egr is cleaned and moving easy..
no computer faults..

As far as I'm aware the selenoid valve only controls the EGR valve not the turbo so can't help with the second photo.The selenoid valve opens the EGR after a command from ECU it reduces the pressure on the upper part of the diaphragm within the EGR so as to let a limited amount of exhaust gas to pass back to the inlet manifold. The white smoke you speak of could be un-burnt fuel take a look at the dipstick is there fuel in the sump,is the level to high. If fuel is getting past the piston rings it will be washing off the oil in the cylinders not a good thing.
