    1. You cannot swap eeproms on that DME. Only a BDM read can do what you need on MS45.0/.1.

    2. You ABSOLUTELY need to put in an MS45.1 if yours was MS45.1. But it shouldn't matter what part number.


    I have a spare MS45.1 that I can prepare for you.
    If your original DME is still somewhat workable on diag line, send it to me and I can get it all done. Send me a PM with your email address.
