Mein Auto: 540i
This thread has great information. I have a 2003 540i that has recently had some battery issues. I replaced the battery in May. It appears to not be holding a a charge - specifically overnight. I checked the Alternator output while running and it is at 13.5v when idling. I am thinking this is a bad battery. Any ideas?
