Bmw Exterior Lighting Turn Signal Switch

Question? My door lock do not work and my battery is dead. I was told there is a positive connection beneath the car by the passenger side, which will give enough power to unlock the doors if hook up to a power pack. I am a owner of a 2000 4.4i X5

This car cathes on fire!

2003 BMW 525 catches on fire, could kill you!

i turned my car on and the steering wheel is so hard to turn that i cant drive it...what could have caused this?, because it is also shutting off by itself.
