I sent original dme off for hopeful repair but have the dme I purchased from junkyard. I want to learn how to program. I have bmw tools. I read I can virginize the used dme but no idea how to. Also would like to do ews delete. Actually saw a program for that. Just found out how to make bench top harness for it. Dme part number is 261 209 002 and is 05 bmw 645ci. I don't currently have the old ECU as I've sent it off. It's killing me waiting for it so want to try to do this. Any help would be greatly appreciated. Oh, used dme I have is from 03 bmw 745i
