Two problems related to electrical failure have been reported for the 2007 BMW 530. The most recently reported issues are listed below.
Vehicle sent error message about passenger side airbag failure in the am, complete electrical system failure in the evening when I went to return home. Dealer found water in trunk, below spare tire. Trunk above spare tire was dry, no signs of moisture. We experienced heavy rainfall on 3/17. Electrical system is fried - vehicle is inoperable. Appears to be failed sunroof water seals per BMW service bulletin si b 61 13 06. In my professional opinion as a mechanical engineer, this is a design flaw. Multiple owners' forums concur.
Water collects in spare tire well, battery well, and passenger front headlight, causing massive electrical failure. First occurrence was 2009 after ownership of this used BMW 2006 530xi wagon from the BMW dealership. The second occurence was 23 may 2011.
