Battery problems & yes a power drainf?
I own an X 5 2001, 4.4i V8.... The car has died upon me recently. I've noticed alternating problems with windows activating themselves and rolling down when driving, sprinkler systems working sporadically, air conditioning system not working for day's and suddenly working perfect. Central locking system sticking asif not enough power was getting to the locking mechanis to open and close the car. I've noticed upon returning to the vehicle the central locking system had somehow unlocked the car. Though I was going mad at one stage, but I haev confirmed this as actually happening. I was about to seek the services of a young priest and an old priest(exorcism). SO you are all not alone and I'm about to delve in to the unknown ina bid to get the problems sorted.... Thank you for all your posts... hope this helps to confirm what we alreasy know...
I'd start with a new battery & leave a trickle cha
rge on overnight. My 01 had similar problems and it turned out my alternator was overcharging and killed the battery. But at an earlier time I had similar things the first battery just got old and I replaced it. The weird things still happen on occasion. My passenger window once rolled itself down in a driving rainstorm when I was not in the car. They roll down an inch on occasion. Keeping the voltage right is probably the key. My old 750 did similar things when the battery was getting old (or when I listened to the radio too long without the motor running). Mixing the blood of a brown chicken mixed with dried bat wings and dribbling around the car on the night of the summer soltice seems to work, but you missed the date and now you'll have to wait until next year. Old priests don't do any good. I think Hooters girls will work, but I haven't found one to try.
Re: HELP--Dead Battery / Dealer Rip Off?
I just picked my 2007 X5 up from the dealer - 2nd time I had in for maintenance for "excessive battery drain". First time they told me I had "unfavorable driving habit" which, if you crunched their numbers, my starting/stopping the car 3x day was "unfavorable". Let's see - that is going to work in the AM, maybe lunch or a meeting during the day and driving home in the PM. This time they told me I don't drive the car enough to charge the battery. I leased the vehicle in March 2007 and have 10,000+ miles - my daily commute to work is 25 miles minimum. I have yet to experience the "dead battery" but I know it is only a matter of time.
Hogwash. 25 miles is ample to charge battery
and to dry out exhaust. You should not be having a problem of any sort.
I agree, ask to speak to the service manager

Re: DEAD BATTERY: HELP! how do i replace it myself
I don't see a response to the post about how to change the battery without spiking the circuit or loosing all the settings.
I'm now looking at changing my battery as a preemptive strike (it's seven years old, talk about borrowed time).
I'd like to know if you can use a solar charger through the accessory plug to maintain power.
I'm located in Toronto so don't have access to the wide choice of batteries in the US. Anyone got a good suggestion other than original equipment?
Longer than that! Try 8 years.
BMW batteries can last a LONG time at least in my experience:
1997 328iC (BostonGrun): 8 years OWM, 3 on replacement so far
1997 328iC (Hellrot): 7 years on OEM, 4 on replacement so far
1999 M Roadster: 1 year, replaced under warranty, presently at 8 years and going strong.
2002 X5: 6 years so far... and I've run it flat once...
If you are getting only 3 years out of a BMW battery, something is seriously wrong.
I keep these cars ona BMW battery maintainer when not in use (storage).
It is NEVER a good idea to try to recharge a totally dead battery using your alternator alone. If you are lucky, you might get away with it, but it will put quite a load on the alternator, and some brands will overheat.

Re: I'd start with a new battery & leave a trickle cha
This has haapened to me - 02 X5 flat battery , replaced two weeks ago and same this morning ! Just wandering having read all these threads if my IPOD is permanently charging (through an ICE connection), have never thought to check until now.But would that be enough to drain a new battery in two weeks flat ?
Not just iPod charging...
These new cars run a lot of juice, even with everthing apparently "off". Locking the car and setting the alarm for instance, can really suck the juice.
If you can, have a tech check how much current draw there is when the car is off - should be only a few milliamps. If it's anything more, start pulling fuses to locate the drain; often a sub-unit has failed and draws excess current.
