hmmm i own an 06 330i and its been in storage for alil over a year. i wanted to get it back on the road so i insured it 2 days ago and it wouldnt start. figure the battery is totally dead so i tried charging it over night, it didnt work. i tried jump start and it work. let it run for about half hour and i drove it around the block it was running like it was brand new. but once i turned it off wont start again. i jump start over it works then dies when off... anyways i dont think the batt holds the charge! i hope its covered.
i have warrranty in the car, i called the dealer and have an appointment this coming weds. well reading your posts i hope dealer can replace my battery! kinda weird everything works perfectly before i put in storage!!!
will soon find out!
