E60 / E61 (2004 - 2010)
I have 2005 545I V8 & 4.4L (has 170000 KM). I put the car on the storage for winter and took it out in May 2013. My battery drained completely, so i had to give a Boost. car started but with so many lights came on (BATTERY TERMINAL, including date/time air bag, flat tire etc).
