Sounds like the exact same issue i had... BMW can check it for you for a couple hundred, and another couple hundred for a reflash. these things get expensive. with that said, you can run on an EWS bypass, not the best idea, but you can. The only EWS bypass I run are on my swaps. Wiring is usually the issue in these cases, but if your luck is as bad as mine, you may be in the same position as I am. Since you can pull up your information with your EWS, you may be able to catch a bmw tech, around here or bimmerfest (hell, even reddit) that can do a better job than me at translating it. I work with my hands, not the computers. S'pose i'm doomed for future cars. Best of luck, man!
