I've left my car in garage for over two months. now the battery is dead

Get some jumper cables and go to work! The proceedure is in the manual. Your clock will be reset, probably your power seat settings, mirror settings, and your HVAC settings will be erased as well. No biggie

thanks

lights are on, but can't start the engine, why????

when i try to start it, all the lights are flashing.

give it time to charge. If you're really that worried, call yer insurance... maybe they give you free towing, in which case when the tow truck gets there, he'll jump you and that'll be the end of it. Just go drive for a couple hours and it'll be back to par.

Takes a LOT less power to turn on a light bulb than to crank your engine. As already posted, just jump it, let it run for a while, and you'll be fine. Your battery should be able to tolerate a certain number of complete drains without any problem.

Thanks everyone, I will do it tonight.

Did you try calling the dealership? I don't know how it works with BMW, but I know MB will deliver you a new battery (via the roadside assitance guy) if your battery dies within the warranty period.

yea, definitely call roadside assistance to get the car running; we all pay for the service when we get our cars, might as well use it!

Battery

You have to hook the cables first while the other car is running in order to charge yours. It will take few minutes to have your battery initially charged. You will see once you try it after having it recharge for 10 minutes, that it will start without the flashing and the funny noises from the cluster. Good luck and let us know how it works out :thumbup:
Good luck

:werd: That's what you pay for.

i had to buy a new battery after storing mine last winter... after the battery goes dead enough (doesnt take long on these cars) you have to buy a new one...

i bought one of those BMW battery charges (plugs into the cig lighter slot) and it worked great! stored the card during the winter and started it right up after i uncovered it

thanks everyone, engine is working again. haha...
I charged it overnight.
time is erased.
but, the memory for seat positions is still there.

I totally agree. Even if that battery takes enough charge to start you car, its on its last legs. Start thinking about buying a replacement battery.

the car is not as smooth as before, when I rev it to under 1500rpm quicky and let go. the car shaking from side to side, i can feel more when I am on sport mode.
