Hi, I own a manual 530d ‘04, my MPM module got bad after getting water damage, so I thought it was consuming too much power because of it and it was draining my battery, fixed it, still the same, so we checked the alternator, it turned out that it wasn’t giving any power back to the battery, and it seemed that it was the problem. Replaced it, still not giving back power to the battery, I checked fuse 90 after that, the 200amp fuse, its all good, its not from that either. And now I don’t know what to do, has anyone had a problem like that?

You need to use a BMW specific DTC code reader. It will save you a whole lot of guesswork.
