Question Battery and Coding

There seems to be a ton of scattered information on this, but I have had a lot of trouble getting a clear answer. First off, the Seattle BMW dealership quoted the battery at $512 (!!!) including labor, which is a huge ripoff. I'd rather get a Kirkland battery from Costco and just install it myself. However, this is my first BMW (2007 BMW 328xi), and I understand that you have to inform the car that it's a new battery so as to adjust how the car charges it.

My confusion is this--do I absolutely NEED something like the Bavarian Technic Tool, specifically, in order to be able to reset the battery? Or can I go with something like the one's mentioned here and just use that? I realize most of those are code _readers_, but nobody is very clear about what it takes to write/alter things in the car itself. If there's some magic DIY guide that I've managed to not find, then feel free to point me in the right direction and bop me on the head. If not, I think it'd be great for newbie BMW owners like myself!

Thanks for all your help!

ok here is the thing
if you're replacing your battery with a OEM battery no programming is needed. However, you must register it.
If you're replacing with another brand, you must program and register the battery.
BavTool can only register, it can't program.
Buy walmart battery and make sure you program and register. Otherwise, you will have problems in the future. Speaking from personal experience.

premature battery failure. random electrical malfunctions. random errors popping up on the dash.

So, I'm aware that they'll have issues; what I really want to know is, can I reset the internal computer to recognize it as a new battery without buying (a) over half a grand of the dealership's labor, or (b) a $300 tool that I will use once. I'd love to get one of the Kirkland batteries due to the positive reviews I've read, but I don't want to risk damage to the car or the battery.

Also, from what I've heard, places like Walmart, Sears, etc., lack the software to be able to reset the battery, since this is generally proprietary BMW nonsense. Perhaps someone can chime in on this.

Go to the regional forum and see if there are any local coders in your area. They should be able to code it for cheap. Or ask around independent BMW shops in your area.

Not sure if Costco carries the proper size for our cars. We need a BCI Group 49 or DIN H8 size. A lot of the auto parts store battery finders are wrong, or at least they were for my car.

Yes, that was another thing I was curious about as well. They DO carry the Group 48 size, but not 49--but from what I understand, this is fine too. I am VERY curious as to whether or not someplace like Sears or Walmart can code/register the battery--from what I understand, they couldn't, but now I'm not so sure. I'm also afraid that if I call and ask, they'll tell me yes without really knowing.

As far as getting someone around here to help with it--this thread is kind of a precursor to that, since I want to go into it with some knowledge of what I'm doing.

First off changing the battery is an easy DIY, there is no need to let the dealership do it. They are overcharging you when you can buy the battery yourself for about $160-$300, 10-30 minutes of your time, and last but not least $20-50 at an independent BMW just to get it registered.

By the way I made a thread about this last week here (pictures & videos included)

Thanks! I really don't want to have to dish out that much money to a dealership, though--especially considering you can get the entire battery purchased and installed for a fraction of the dealer's price from someplace else. I'm just confused as to what the limitations of coding are, and whether or not the ODB2 cables will be able to reset _and_ register the battery.

BTW, the existing battery failed two load tests, so the battery itself is almost dead. It's a 2007 with 49k miles on it, so the mileage makes sense.

i believe group 48 will fit, but it is significantly smaller than the OEM battery. no reason to shortchange yourself. stick with group 49 or H8.

you need a special tool or special software. you can't do it with a run of the mill OBD scanner tool. generic auto shops will guaranteed not have the proper equipment to do so. BMW independent shops are more likely to. but like i said, check the regional forum for local coders. anyone with a coding cable and knows how to work NCSExpert and toolset32 can do it.

Had one installed and registered today for $310 at an independent shop.
