It's that time of year where I leave for work while it's dark and get to work after the sun is up. Leaving work last night I found I'd left my lights on and the battery was dead. This is the second time this has happened to me in about a month. I'm used to having a chime (my old VW), but the 530i only gives me the warning message. Is their a fuse I should be checking, something else or does the e34 not have a chime?
