My battery is running dead every two days! I jump it and starts up, after several minutes with the jumper pack cables! This has happened 4 to 5 times since I purchased the vehicle just 2 weeks ago...Am I doing something wrong to drain the battery dead???....I am leaving the key inside the ignition all the time, could this be the reason the battery keeps going dead???....Please help me, OK!....Thanks a Million...Anthony

If the key is in off position it won't drain battery.
You may have battery draw in that vehicle , or the battery itself is going out.(BMW batteries are good for 4-5 years)
Both cases needs to be checked by workshop , cause BMW very sensetive to the voltage drop. When you disconnect battery you may need to perform some settings adaptation after you replace it or connect it back.
New BMW requared to reset computer even after brake job and battery replacement.
