E70 Increased Battery Discharge while Stationary - Page 2

To get back on topic (instead of comparing BMW to MB), I've had this fault 3x now with my '07 X5 4.8. Each time, I turned off the car, let it sit for a minute, restarted and the fault went away. No replacing the battery - yet.

I've had this happen too and they replaced the battery under warranty. I've read that lockinng the doors (even in your garage at nnight) helps the sensors/modules go to sleep sooner. I'm not sure if this is true or not, but the new battery is still holding up.

It ticks me off that I have to put a battery charger on it over night to protect the battery. That shouldn't happen on any car, much less one that costs as much as these do!

Hmm. More to think and compare. But still hope to stick with sportier looks on BMW. Let's hope that my SA can solve these problems on my X5 so that I don't have to switch.

Would definitely consider ML350 if my X5 problems can't be solve. Thanks nynd!

I wrote about a possible fix in April. I had the following parts replaced:
Replaced Battery 61-21-7-594-976 (made in Italy)
Replaced Battery Cable 61-12-9-215-954
Replaced Battery Cable 61-12-9-217-004
Replaced IBS and BST (no part nrs, one is Intelligent Battery System, no idea what the other is).
Not saying this is the solution, but I have not seen an error
message since.

Here is a pic of the IBS (top right).

Here's a better pic. It's the black part with the Rolls Royce, Mini, BMW logos:

OP-

First, threatening this board with talk of "having to switch to MB" is just silly. Seriously. Half of your thread will now be argument on MB versus BMW.... and honestly WE DON'T CARE ABOUT YOU OR WHAT CAR YOU DECIDE TO DRIVE. This forum is not "BMW Corporation". Threatening it will not motivate a solution.

OK?

Now, once you've gone to the SA, keep in mind that there is a notorious issue with drain. Is this original battery? If so, I would just replace it but not at a dealer- save yourself $200. Once the obvious stuff has been checked, there is an BMW SIB for battery drain, and specifically how to test for this. If you allow the SA to decide what they will do next, and you are paying the tab, it can be a lng and frustrating road. make sure you bring this SIB to his attention early on and make sure you have this explicitly listed in a work order. if they fail to do it and ultimately it turns out they have to do it- you have some leverage.

Good luck with getting the X5 fixed. And if not, MB makes a fine car.

If battery needs replaced and OP has an 08 model, wouldn't battery be covered under new BMW warranty? No need for purchase from dealer or autozone.

I/some of us US based posters don't "know" what the warranty/maintenance program is, in Qatar...

I recall several posts of people having difficulty getting their batts
"covered" by BMW, even early on, under warranty. Back at the ranch,
I hope the OP's dlr figures out the drain or the problem and gets him
back in shape.

BMW in Qatar come with 3 years BSI 60,000 km and warranty. So, I'm a bit lucky. Still got another 7 months of warranty left.

BMW SA are crooks... the BMW techies are idiots... never will i buy another BMW do to poor customer service!

I had a battery drain problem also. They claimed that it was the aftermarket stereo system that was installed because supposedly someone spilled some liquid onto a loom of wires. I told them to take pictures of the area before they cut and splice in new wires and what did they do? They replaced the supposedly damaged wires without taking the pics like i asked them to. total cost? $1000!!! i still get the high discharge alert at times.
