How do I jumpstart my 2008 BMW 328i? I accidentally left the lights on overnight and it’s completely dead.

That’s an easy mistake to make, but no worries! You can jumpstart a 2008
BMW 328i
back to life by following these steps:
  • Open the hood
    of both your car and the car that will be providing the jump. Both cars should be completely off.
  • Connect one positive cable to the working car’s positive battery terminal.
  • Now, connect the other positive cable end to your BMW’s jumpstarting connection point. This point is located in your engine compartment and is labeled with a + symbol.
  • Attach one end of the negative cable to the working car’s negative battery terminal.
  • Attach the other end of the negative cable to a piece of plain, unpainted metal on your car’s frame.
  • Start the working car and let it run for about five minutes.
  • Try to start your BMW. If it won’t start, let the functional car idle for several more minutes before trying again.
  • Once your car starts, let both vehicles run for a few minutes to allow your battery to recharge.
  • Finally, turn your engines off and disconnect the jumper cables in the reverse order that you attached them.
