It sat for two days, I tryed boosting it.... Nothing
The headlights flash off and on when I try to start it, and the starter doesnt sound like it is even trying to start.
Any help???????

Do you have a trickle charger? If so, I'd put it
on, (connects under the hood), for a night.

If still no go, my guess is the batt's gonzo.

If it won't start with a good jump start then it's time to try a new battery. Be prepared for the dash to take on a seasonal look. (Light up like a Christmas Tree.) Simply turning the steering wheel full in both directions should clear that.
I had a Exide fitted to my X when it died. Came with drain and 6 year warranty for $90!

If you still have the original battery in your 01' consider yourself lucky and run out and get a new one. X5world has links to suppliers of OEM batteries for half the cost of the dealer. Good luck

That happened when my alternator went bad. Hope it's just the battery.

Sounds like the battery.
Just for kicks, try unlocking the drivers door with the key before you start it. It disables the factory alarm.
This happened to me once but the siren was going off as well.

Try another key....

Just had the same thing happen to my X .. sitting for 4 months while out of the country, came back, X is dead. Tried the trickle charger, no good, tried a big charger overnight, started up. Drove for 30 miles on the highway, came back, shut it off, tried to start it right up again, no good. Batt was definitely gonzo....

Uh oh my X is parked while im away for a month it better start when I get back...

Is it normal for the xenon lights to flash on and off when the ignition key is turned? They are flashing, which would say there is some power left. But no start!!!! I'll try the trickle before buying a new batt.
Thanks
