Chosen Solution
I have a 2005 BMW 5-Series E60 that is draining the battery when it sits for days without use. I have a relatively new battery. I have disconnected the negative terminal of the battery, and I am pulling 3.3amps of current! I have systematically removed every fuse in the trunk fuse panel, and the panel behind the glove box while monitoring the current. No change to the current draw with any fuse. I have “re-registered” the battery using a code reader, and cleared all other errors. I continue to get an “excessive discharge” error. Are there any other (unfused) points of current draw I should be looking for?
Try disconnecting the IBS (Intelligent Battery Sensor) Here is a YouTube video Explaining the procedure. https://www.google.com/url?sa=t&source=w…
