battery drain

Just got a message "high battery drain" Later that day, the car was dead. I started looking on the forums for this issue, and it seems to be a real PITA. Is there anyone that had this problem and had it resolved completely. I already replaced a battery.

it was 3 yrs old. I thought it might be easier just to replace to remedy the issue. Brand new battery, still the same message.

battery drain

Is your SOS not working? If so your Tcu module is bad, and it needs to be replaced by someone that can code the replacement unit. It can cause the high drain picture.

So 2010 vehicle...zero issues...then three year in you get a single high battery drain warining and you replaced the battery.

Did you drive the car 50-100 miles to fully charge the new battery?

What are the circumstances aroudn the warning 'remaiining'.

Did you 'register' the new battery? Not saying that is the issue, just asking.

We really need the details of how the car was used and how this warning remains to be able to provide guiance.

"Brining it in" may be unrewarding....

Krysfry,

I have a similar problem. 2007 X5 with only about 27,000 on it (I don't drive it a lot).
I'm on my 3rd battery. The original was replaced under warranty with a BMW battery. That failed after about 2 years and dealer indicated it might not be covered under warranty. I bought the best Interstate for the X5 (4/2011) and yesterday after washing the X5 it wouldn't start (had doors and tailgate open while drying the vehicle). Also if I have the radio on when turning off the vehicle, the next time I start the vehicle the radio will be off instead of on like I left it. What is the deal with battery "register"? The BMW batteries are about 3-4 times more expensive than after market?
I keep the vehicle locked when in the garage to shut down some of the systems.
Is this caused by not enough driving of the vehicle or what?

Gunner

The cause is poor design, plain and simple. It looks as if I'll be getting battery number 3 soon, with 16,000 miles on the car. I've never heard of such a thing. Don't go to the dealer for a new battery..if you know for sure that it's a battery issue only, which I highly doubt. I was quoted about $300 from a local euro auto shop. They have a way to put the car on "life support" while the battery is being changed out, so no coding would be needed. Good luck! I guess you can take heart in knowing that you have a very large support group sending you well wishes.

thanks, got the car back last night. They just told me there is a draw, and I would have to leave it for couple of days to find where the draw is. I took it home, and so far no message.

Guys- common issue, a lot of info found by searching.

THe BMW system uses various busses that have modules attached- these modules typically draw little power until the car is started and things running- HOWEVER, bad moudles can cause error signals onthe bus and/or 'wake up' various modules and thereby cause 'parasitic drain'. This repetitive 'draw/drain/recharge' eventually kills the battery.

Many posts.

You need to have an overnight (or longer) test donw whereby they monitor all this to try and ID what is waking up and causing this.

The problem is that few dealers do this, and just tell you ';drive longer' or 'buy a charger' It is hard to fin/fix/ There IS a BMW TSB on fixing this.

IMO it is totally worth it to prosecute this under the warranty- when you are paying it will be ugly

Ard,

Do you know what the TSB is or do you have a copy? I get no error messages.

No. Search here and on xoutpost. Multiple people have had this issues back years... there isnt "one cause" which is why it took so long to figure out. Initially BMW blamed 'short drives', but it became clear that other drains were causing it- not just ONE module, but errors in different modules would cause items to wake up and draw current.

No 'battery drain' warnings or anything like that? Hmmm. The 'registering' is to reset the car's adaptive charging algorithm to tell it "this is a new battery, charge it like it is new". Over time the algorithm makes allowances for the battery aging. If you just replace and dont regiaster, the new battery may not last as long. Also, if the replacement battery is a differnt size/capacity, you will also need to tell the car... called programming. Both items take 5-10 minutes with a BMW computer OR with a software app loaded on a laptop and a special cable (ebay).

Just got the "High Battery Drain" message for the first time (2009 X5 30i). Let's see if it appears again. It may be time to replace the battery. It's just about 4.5 years old.

I think you are lucky to get 4.5 years out of a BMW battery, but what do I know. I went to the best Interstate battery, much cheaper and appears to work fine. I did fully charge it after I put it in my X5.

My E70 (2010) 4.8i is about to go in for the third time on this. Last time (2-3 months ago) they replaced the battery under warranty.

I suspect this is an ongoing issue with the vehicle. Do you think BMW will let me see the past history prior to purchase? I got this as a CPO about a year ago.

What would that change??????

They will likely not let you see it. All it will do is piss you off and cast blame on them for not disclosing a material defect.

Read up on the SIB for diagnosing parasitic battery drain overnight. Then get the dealer to do it.

If you have more than one BMW dealer close by, I'd go to another dealer and have them pull up the VIN and BS then to try and see the docs.


Also about every quarter or so I will put my battery tender on the X5 over night to fully charge the battery (a PIA, but it helps). I only drive about 4K a year, I only have 29K on my '07.

Looking to replace 2009 X5 orginal BMW Battery for first time. dealer is quoting $400. Any suggestions on aftermarket alternatives ? Is changing the battery a complicated matter? Does it require re-programming stuff?

Have you done any reasearch/reading???

You can get an exacts (size and capacity) AGM replacement and install it easily- just hand tools.

You SHOULD get it 'registered'... a simple single software 'click' that takes 5 minutes. Not "Re Programming". Just tell the car "new battery"> BMW will make it sound complicated AND essential, in order to make $200 profit on this service!

I got the best Interstate there was for my '07 and installed it. Like Ard said just few hand tools and a 9 volt battery and adapter plug to plug into one of the outlets so you don't lose all of your settings ( but if you do, no big deal). Also after I installed it I put the battery tender on it overnight to make sure it was fully charged before running the vehicle. Figured I saved 200 to 300 dollars. I don't how to register it or if only a BMW battery can be register, maybe somebody here knows.

Any battery can be 'registered'... it is something that is done to the car, not to the battery. Just flipping a software key to tell the cars charging algorithm 'the battery is now new, reset the parameters'

Purportedly if you do NOT, the new battery may not last as long. But saving $300 you can buy 2-3 time AS MANY BATTERIES by avoiding the dealer.

I too have the battery drain issue. all wiring and battery was changed at the dealership 1yr ago and problem is still going on...it's never not started, I have a feeling it has something to do with the cd changer as it makes noise...any op's on the possibility of it being the cd changer, any suggestions on a diy resolution?

In the past mine has not started. I guess I (we) just learned to live with it, which not saying much for BMW. You might want to buy a battery tender and try charging it until the tender light tells you it is fully charged (remember mine is an '07 with less 30K on it). It is kind of a PIA, but it is cheaper than a new battery every year, especially a BMW one.

"All wiring"?!?

Impossible.

Did the dealer run the SIB for diagnosing battery drain? (They hook the car up overnight and monitor modules turning on and off. There has been no "DIY resoultion" I am aware of. You could unplug the CD changer for a few weeks.
