Mercedes Sprinter 906 2007 ECU Replacement

Hi.

We have a 906 2007 Sprinter with blown injector driver. Customer has a scrapped 2nd Van to take parts from same year, same ECU part numbers. What items need to be swapped apart from engine ECU, EZS and steering lock for the Van to start and function properly? I have SDconenct and XDOS to work with.

Thanks and regards.
