Good Day Fans
I have 2005 525i E60 N52 engine blown engine . I bought a replacement 2009 N52N engine. Swapped out old engine and harness with replacement harness and engine. I have no spark when attempting to start and fuel pump runs continuously.

I Put the car on diag all ok in the interior of the car except the engine ,we cn see the dme but not passed it. Could the DME be the issue that I need the dme from the N52N or would I need the old harness.

Desperate please help
