Got a jump to leave work, picked up battery on the way home. Got home took out old battery (which still had a green light). Went to put in new battery and it is too big. BMW batter is 13.5" new battery is 15". Question - since battery is "green" does it need to be replaced. Its the original battery in a 2007. During the 2 day fiasco sometimes the lights came on, sometime the car was completely dead, sometimes the key would get stuck and it sounded like the car was continuing to try and start. weird. Any ideas on what the problem is and if it is the battery how do I find the correct size. btw - getting to an actual BMW dealership is about an hour drive each way. Please help.
I just replaced mine a few months ago from an 07 as well. It's probably about time. Mine turned out to be a bad cell. Take it to an advanced auto and have them test it. I purchased my battery there as well and fit perfectly but make sure that you have your new battery programmed at the dealership. My dealer charged $100.00 to do it.
