Hi guys. I have a parasitic drain on a 2002 BMW 330ci E46 that is drawing about 1.2 amps. I disconnected the earth lead and put a multimeter between the negative post on the battery and the earth strap. I then shut myself in the car and waited 20 minutes to make sure it was in sleep mode. I then removed one fuse at a time to find what was drawing the excessive amperage. But nothing made a difference and now I am stumped! I'm not brilliant with electrics. Is there anything else obvious to check before paying someone to look at it? The alternator seems to charge fine, no light on the dash and car always starts after a run. The battery was replaced a week or so ago as at first I thought that was the problem. Help!!!!!
update. Apparently there is more than one fuse box and someone has suggested unplugging the alternator. Just wondering if there was a common fault that's worth looking at first. Tried kicking and swearing at it, but that didn't work!
