drain

Hello. I recommend replacing the battery.3 to 4 years old is long life for a battery although batteries that live inside the vehicle usually last a while longer.Also use a amp clamp to check for drain.it is a meter that hooks around the negative cable.it should be no more than 250 milli amps,there is a 1000 milli amps in 1 amp.make sure when checking for a drain that there is nothing on .if door is open roll the latch,you can always tell when bmw goes to sleep because the park shift light goes out. replace battery start fresh.goodluck
