Hi all,

I've been reading this thread: http://www.e90post.com/forums/showthread.php?t=532315

... but since I haven't yet ordered the cable/battery its very hard to follow along. I'm picking up a DCAN/OBDII cable to put a new battery in my 2008 335i, and want to make sure I can use it and the software that's out there to both program and register the battery.

I was going to get this battery: http://www.walmart.com/ip/EverStart-...ttery/16782659

... however it has different specs than the OEM battery (760 Cold Cranking Amps). The thread above (post 2) states the process is only for OEM batteries. What would I do differently? Is there a "how-to" for non OEM battery replacement?

Thanks!
Ben

You have to code the closest amps in klasse_batterie under the CAS module. After that open up tool32 I believe and follow the new battery registration like normal. There is a guide around here somewhere

What you want to try and find is the reserve rating for the battery.
If this battery is the same one that is sold at autozone (just under a different label), then it is somewhere around 150. If you divide 150 by 2, and add 16 (a formula I found on e90post for converting reserve minutes to amp-hours), then you are left with 91Ah, which is closest to what your car is already coded to.

If its at 91 ah then no need to use NCS to change the amp rating in CAS, Go straight to Tools32.

Thank you. You don't happen to know where that guide is, do you?

Is it even possible to find the reserve rating as it's not listed in the specs. There is also an Autozone nearby. If we know their battery is the right fit to not have to do any modifications, should I just go that route?

Here is the autozone one, it's not the same as the CCA is different, it's got 790 CCA and 140 reserve for $164: http://www.autozone.com/autozone/par...3386_636952_0_

or Advanced with 765 CCA and 140 reserve for $166:

Open up Toolset 32 (located in EDIABAS/BIN folder):

1. Open MSD80.prg
2. Look up steuern_batterietausch_registri. (near bottom of job list)
3. Go to Jobs menu
4. Select Start Job Only Once

Look in the Results window for the line JOB_STATUS = OKAY

Can also perform in EasyDIS. After I completed Registration using Toolset 32, I verified with EasyDIS that Registration was completed.

Also, if Toolset 32 comes up in German you can go to configuration tab, toolset, and select English.

Actually, I'm not sure this process is accurate.. My OEM appears to be 160 and 90Ah. 160/2+16 = 96, not 90? Will either of those batteries with 140 require adjustment in the settings?

Yup, this process is in the thread I linked to, just trying to figure out the specific process for non-OEM with different specs. Thanks for the tip on English language.

Thanks,

Hi, I'm having a bit of issue with this. It appears as though Tool32.exe registered the battery, but ignition still shows a white dot. My full post in the CODING SUCCESS thread:

Also, to verify with EasyDIS, is this the most up-to-date howto you know of: http://forums.bimmerforums.com/forum....php?t=1297683 ?

Thanks!
