First check drive belt tesion, alternator output(at the battery) if ok:- Park car securely open all doors and bonnet boot etc leave for 24hrs so ecu's sleep. Without closing or opening any doors check with a volt meter across all fuses for a draw, drain. Once you find which fuse still has amps being used you can isolate and test further by identifying the funtion using the chart on back of fuse panel
Welcome to the world of BMW's. return the car to the seller. you got a bad one. You got an electrical short draining the battery. Bring a blank check and sign it over to the dealer. They're going to have to run through the entire electrical system to find the short. That work alone is worth more than the a used up 2001 325i.
