Electrical Demon---- Depart![emoji317]

Just sharing this episode.
You can move to the X3 e83 area but first get this...!
Readying for a 900 mile trip with my most reliable X the 04 e83 215k not my X5.
Anyways...
8 mo old battery.
Gas tank full.

I get in, car recognizes key
ignition turned and then silence.
Must be the battery...?

Charger indicates full...

I wiggle the power jump start cable at the port box under hood.
Turn the ignition... nothing.

but the shift light is on...04 is not sleep! Still nothing from the ignition.

I open the doors crawl to the trunk with a screwdriver in hand.

Lifted/removed the floor trap door after damaging the lift handle...that hurts

Wiggled the negative battery cable... nothing

Popped the release for the lift gate...well glory be! Seems like the whole garage lit up so brightly along with the tailgate.

I then return to the ignition and the old Sopwith Camel started right up!

Here's what the dash indicated:

Had to reset:
*Clock
*Trip meter
*Windows
*Steering, lock to lock

Last time I drove it.... yesterday
Last thing I done to it...
A)Changed the wiper blades
B)gassed up two days ago


Can't truthfully recall if I heard the fuel pump or not I had it replaced maybe 5 years ago.
Have cranked and started her at least 5 times since no problems.

I can't explain it can anyone else?

We did have (off and on) wind storms in the area yesterday.
But car was in the garage...

What is the sleep relay called again? It may be sticking a bit. I know if headlights don't come on when the key is turned, it won't crank up. Mine has an electrical glitch now and then. Mostly went it takes amps to crank it over.

Thanks for the reply...
Travel plans postponed...
Just as I was finishing up the car for the next early morning trip...
The demon struck again while backing half way into the garage.
Spent 45min trying to revive her...
no go!
Had to get the other X to push the 04 into place.
Closed the garage door in disgust!

I think just maybe it's the electric latch for the tailgate.
I'll have to remove that plastic panel....but not today!
Total disgust...

I don't know the e83 platform that well but if you had to reset the clock, windows, trip counters etc. then it sounds like a full battery disconnect event.

If you are sure the battery terminals are good then maybe the BST is suspect...? Or one of the links/fuses in the terminal box near the battery?

Ahh, didn't think about that,,, definitely worth looking into...thank you hope it's for sure tomorrow morning.

Pull the latch fuse for one night. Or do a voltage drop across the fuse.

Yep! That was it!
Just gave it a squeeze (as you can see)
And we're back in business...
