So it's really bizarre how anything could drain my battery. I don't even leave anything plugged in. I honestly think it's the alternator.
Thats good to know, but FYI even a base car has about 50 or so control units.... any one of them could be failing internally and be a draw on the system.. In all honesty, BMW alternators are pretty good.. they dont fail as much as you think it may. On the other hand BMW batteries are the worst thing ever invented..
My guess is they will check the battery and it will fail after recharge and they will replace it.
