More and more things are potentially 'on' in the modern cars even when the ignition/switch is off. Since they are essentially run by computers (often many more than one), and you don't want to wait for them to boot up when you want to start the car, they go into sleep mode. This does not mean that they stop drawing power, but it gets to be quite small when everything is working properly. The older the car, the less it has that may still be on, until you go way back, then nothing is on at all except maybe a clock.
 
No battery likes to be deep discharged and will be degraded each time it needs a jump start.
 
For a vehicle that is not driven much, or, has lots of short trips especially in cold weather that taxes the battery even more, it's a good idea to purchase and USE a trickle charger. This is becoming true of ANY new, complex, modern car; not just BMW. The more do-dads there are, the bigger the problem. Think about it; stuff like the remote receiver needs to be on all the time so it can respond to you pressing the open button on the fob. Most of these cars have an alarm system with ultrasonic detectors (or maybe radar) that try to keep the vehicle from being stolen, or at least make some noise when it happens, and, a gps system might try to turn on once in awhile so you get a quick position fix when you actually do turn it on.
 
Now that I'm retired, I may need to take my own advice. I pick up a new GT in a little over a week (well, I drove it in Germany in APril, but it's still new). I've been filling the tank on my current vehicle maybe once a month or two..not many miles.

If you have comprehensive auto insurance it should cover replacing the electrical panels caused by water damage (less ur deductible). Best if your shop can move the panels to the left side of the trunk instead of their original location at the bottom of the trunk (because your drains will continue to have the risk of being clogged by crushed leaves if you use your sunroof at all). My BMW dealer would not relocate the panels so I had to go to an independent BMW repair shop (Dinan Cars in Mountain View, CA). Good luck!

i think the negative battery cable with the ibs sensor cost around $ 270 from the dealer, replacing it should be easy. They don't sell any parts of the cable by itself, I needed new bolt for the negative terminal, dealer told me I have to buy the whole cable with the ibs sensor and terminal, LOL ....

I am having the same problem many have described about the battery dying. I had my 2008 BMW towed twice last April within three days due to the battery being dead. The strange thing is my car was serviced a few days before the problem started happening. The second time my car was towed I demanded a new battery; they replaced the battery. I have now reached the end of my warranty. I had my car serviced last week and wouldn't you know it three days later the battery is dead and would not start. I had a mechanic charge the battery and took it back to the dealer. They are checking to see what happens when it goes into sleep mode. I was questioned about if I had left any items plugged in like navigation or radar detector which I answered no. Also was mentioned about driving short trips. I drive it everyday to work which is 22 miles and every other weekend for 150 miles on the highway. I asked if this was a problem other owners were having and they said no. Now I read here many are experiencing the same problem. BMW needs to step up to the plate and fix this issue! We have got to get together and form a combined effort to get BMW to address the problem!

Guys, I have a 2007 530i CPO which i love. Never had a problem with it, still under warranty until JUNE 2012. BUT - in 2010 I noticed something wrong with the idrive. Took it to the dealer. They called me and said one or two of the battery cells were dead. Truth is, I don't do a lot of driving. In two weeks, I drive maybe just under 300 miles. So what the manual says, I have to pay attention to that about driving the car sufficiently. Anyway, replaced the battery at a cost of something like $300. Problem gone. All systems operating beautifully, vehicle has about 42K miles and never needded a thing except oil changes.
Remember something: these new vehicles ALL (Audi, Lex, etc) all have sophisticated electronic systems. Even Hyundai now has a push button start for example. I'm use to sitting down at the beach with the car radio on (former 1996 328i) but back then, there were no iDrives. We just have to be aware, these systems draw more current from the batt.
 
Re Sunroof: i learned the hard way in my 1996 328i, those sunroof carriage assemblies can go bad. Now, I NEVER open the sunroof (why do you need to?) Just use it for the beautiful sunlight coming through, and keep it closed. And you won't have to worry about that problem. Keep it simple guys. Don't blame the vehicle. You think Mercedes is going to be less complex?
 
I love my car otherwise.

This is a response to brngmynwtcha's post, have a '08 550i which just got back from a routine service which I paid $1,200+ for and also Paid $69.95 for a vehicle scope check which is supposed to be a multi point inspection apparently that a profit for the dealer since battery died completely 2 days after getting my car back which makes me suspect, of the multi point inspection since they never detected this issue. I also see high battery drain error messages on a regular basis and have to reset time and date a lot, this started happening while car was under warranty, dealer would keep my car for days and tell me they were doing draw test on every single system and would call me after a week and give me a BS solution to the problem, last one was my rear comfort access was faulty and was replaced at no cost to me and this fixed the problem but started having same issues a month later!!!! Car is awesome except for this major electrical / battery issue.

I thank you all for posting your battery issues. I have a 2009 528i that left me stranded in a parking lot. Called tow truck to take the car directly to the dealer on a Thursday evening. Come Friday, I was told the car was ready for pick up and that all it had needed was to recharge the battery. I showed up to pick up my car on Saturday. After browsing the new models for a while, decided to get it appraised for trade-in value. Would you believe that they ran it , parked it and then could not start it again! Well, it was obvious that I would not be going home in my car that day. So, I gave them the keys and traded it for a X1 which has less bells and whistles.
After reading your postings, I'm relieved to know that my suspicions were correct. At least now it will not be my problem and the Dealer will have to figure out and correct the problem if they want to make a profit.

#35 of 35 Horn Blaring, Dead battery by safeman7

Mar 20, 2013 (5:58 am)

I just encountered a battery issue with my 2007 525XI and the car is still being repaired (4th day). I left my car at the airport for 3 days for a business trip. When I returned the driver front window was open and some water was on the back floor. The car wouldn't start and the horn blared. I got a jump, drove for about 5 minutes an the horn died out. the next day when I went to start the car, the horn went off again, Brought it to BMW. They said the battery was at 60% charge, probably low voltage caused a module to blow and a short in the steering column and bad wire to the tire sensors. All this for a low battery which I did not have a warning about. oF course the car has been out of warranty for 8 mos..The car has been fine until now. Has anybody experienced this.
