Mein Auto: 06 BMW 530i

Hello joining the BMW world for those having battery issues with there 530i I do know that there is a problem that they suffer from which is the ground wire in the back of the trunk where the battery is located has some sort of smart relay attached to it that controls how much charge comes out of the battery that goes haywire and starts to drain the battery I had this issue and fixed it myself purchased the wire that come with that link and installed it never had a problem again the part was 250.00 but it fixed the problem hope I was of help.
