Where does this wire go?

Draper · 05-02-2013, 10:20 PM

Long story short, my battery light has been coming on lately and upon inspecting the battery I noticed this loose wire.

Does anyone know where it goes, or if it's even supposed to be connected to something?

Thanks!

Not sure about that wire, but my battery low warning light came on, all kinds of other erros popped up too. Once battery was replaced, they all stopped.

If you have a multimeter, check the volts of your battery sitting. If its less than 11.5, get it replaced. Mine was at 11.1 and still started the car just fine but I guess anything under 11.5 is considered bad.

Good luck.

sounds like a connector to reflash, if the battery needs to be replaced.

Haha that cable is for pdi. Inspections. When the car is droped off at the dealer . They have a battery disconnect switch attached there so the truck drivers can load and unload the cars hit one button and it disconnect power to the car for transport. Before you even get the car the dealer removes it and sends them back to bmw so they can be used again. So that wire is used for nothing after your car has been droped off at the dealer from the factory!

Thanks for the replies.

I guess it's just time for a new battery.
