HELP!drivetrain malfunction f30 intermittently

[Memedalji_]

Ive been getting drive train malfunction intermittently when powering on my 328i.
 Ive had to power it off and on 3-5 times until the error goes away and turbo works, until I power off the vehicle.
 Upon scanning, it seems the error code says wastegate actuator soleonoid. 
 I know it works,  maybe it has to be coded as the engine has been replaced on this vehicle?
How can I code the ECM to recognize the parts and work without triggering engine light or drive train malfunction?
 Ive tried resetting all the codes and hoping it relearns, but that temporary solves it and ends up error again shortly.
 I'm worried there's a short somewhere, or is it just needing coding? What software hardware do I need?

I got the Bimmergeeks standard tools package, along with E-SYS. How can I write the code on the ECU? What files do I need? Can I get the ethernet to OBD or USB to OBD cable to get it sent through? Thanks in Advance. h

i can check it for you remotely if you have enet cable and laptop with windows system, if needs coding also no problem

Thank you very much. I'll have the cable tomorrow and I have a Windows 11 computer and an HP elitebook laptop which is running Windows 7. I have E-SYS and the standard tools package software, as I was looking forward to experimenting simple modifications and enabling features. I know I'm missing a few files to make the database active. This is my first BMW ownership, and I'm liking everything about it ?

okeii ) that sounds good. Just send me a message when you are ready then we can check what dault memor says and so on
