    Most likely your amp is dead.

    My trunk seal leaked and moisture found a path to the top of the amp and into the connector.
    I found a method of covering the replacement amp and wiring with a heavy clear produce plastic bag.

    In the trunk, remove the drivers rear tail light cover, then pull the trunk liner towards the center to access the amplifier. Do you have a test light or volt meter?
    1, the large red/white wire should have constant 12 volts. 2, the small white wire (from radio) should have 12 volts with the radio on. If 2 does not, pull your radio and check to see if it has 12 volts there. If 2 does have 12 volts, most likely amp.

    This happens a lot, a simple fix just do a search.

    For the OBC - This could be related to the trunk wire loom failure that is also well documented. BMW has a factory repair loom.

    If your amp is dead and you're wanting to replace it, I have the amp pulled from my '98 M3 when I upgraded the audio in there. Feel free to message me here if interested.
