Thanks again for posting these SIBs.

So it appears that the BMW model E70-X5 computer is like all other computers. Occasionally they need to be reminded who controls the power cord

So has anyone found the hidden Ctrl-Alt-Del button yet ?

Buy Back Trade Assist

In my case the X5 is still in the shop. NJ is running more tests and can not figure what is wrong. BMWNA will let me know in 3-5 days if they will do a buy back, trade assist. However I have had other issues besides this drain. All have taken years to sort out.

Bottom line there is an issue in at least some X5s that is chronic (3 batteries) and they do not know what it is. You can battery tend your battery and carry a reserve charger and get by but we do not do that in our 7 year old Honda Accord which runs like a top so we keep it. Why should I do it in an much newer SUV I paid $65,000 for?

Last time my SUV died by the way there was no high battery drain while park warnings the days or weeks before. Just a completely dead battery and auto. The battery was new last June.

I however would take a 335XI especially the new F10 or even a 550XI that I hear about. I would not take any thing made in SC. Sorry but I would not.

I've being a victim of this excessive battery discharge issues since I pretty much got the car back in March 2010. My cars being into the dealership multiple times for this issue.

BMW keep's coming back to the same answer for me at least .... my driver profile. Admittedly, I do drive quite a few short distances in the city during the work week, but these are mixed with much longer trips at the weekend. 100+ miles.

Either way though, my car did not log any control module wake up errors ... and in any case they updated the vehicle software to the very latest configuration (per Jan 2010), but I've still seen the battery/clock reset issue. I don't have any aftermarket electrical equipment connected to the car, and I made a habit of removing any iPhone/iPod that might be charging from the car.

I think one day, the battery was so low, although the car did start, it caused all sorts of fun and games for the vehicles electronics for 1/2 hour or so of driving. The iDrive was going nuts !

Not sure what more to do at this point. Fortunately its never got to the point where the car has failed to start ... but it doesn't exactly inspire much confidence ... after all, you may find that if you leave the car for a extended period of time ... you might come back to a completely discharged car ! SUX!

Meister,
Trying to understand your point. Both these lists are the same. THe X5 is not transmitting and receiving Assist/SOS on both CDMA and GSM simultaneously. So far, beyond my dealer, all points to GSM exclusively. Certainly the BT can handle either but that has nothing to do with the Assist/SOS (vehicle's internal phone). Please clarify your point and share your source. Thanks.

Read the lists more carefully. The CDMA listings are from SOP to some date and the GSM listings are from that date forward. For example, E70s built before 4/08 use CDMA and those built after 4/08 use GSM.

RedRockin - I was replying to your earlier post and backing up what you said. I cut that info out of a BMW SIB. You are not reading it correctly; see FunfDreisig's note.

Thanks guys. My bad. Saw the SOP as the only difference. I am not afraid to admit when I do not know something and here it is! Didn't know "SOP"!
