Can someone answer this please!!!

the white smoke at cold start not really anything to majorly worrying about it could even be steam from moisture build up, the smoke smell in the cab when the egr opens two options first option is that egr is leaking not very possible if relatively new, second option is the bellows between the egr and the cooler is not sitting in properly or is broken, it is a pain the in a++ to put this back with new gaskets and clamps sitting behind difuser pipe

 

have not tried this but this will maybe help you guys fix the issue, first thing is make sure that vgt is properly calibrated to that turbo as that can happen, second make sure software in the ecm is updated to lates calibration, a lot of 14-17 truck are having problems with just updates and also check to see there is not corrosion or green dust in vgt connection by the turbo. hopefully this helps never had it happen to me on new turbo install, when i find the exact fix will let you know, if you do any of this and it helps please let me know.

 

Yes i get whistle sound for sure thanks Nas i will visit you for sure once im around Chicago area thanks alot!!!

 

I spray painted to see if i have black smoke around it visually i cant see it unless its on the back side.Another thing it might be my turbo gasket,I replaced the egr cooler for coolant leak and ever since im having issue. Thanks alot again!

 

Thx, Nasriza for suggestion.
Im also going to look for software updates, I don't know if volvo updates the 2010 models.
I"m at 4th turbo on my truck since january last year, and even after inslalling new 3/4 reman motor, (but keept same ecm,), new turbo, engine harness seems like i imported an old isue. Before i used to hear the turbo spooling up quickly , more responsive, more power and was making like jet engine noise, during regen. I don't have fault codes, but seems lazy weaker, like D12, like vgt feature is not working properly .
It was pulling great a couple of times, soon after I washed the motor, I may have a harness problem, miscommunication between boost sensors, ecm, turbo.
