In this video I show you how to change from 90 AH lead acid battery to 80 AH in the DME. Plus how to register a new battery replacement. I show you how to code using NCS Expert and how to register a new battery in Tool 32. We verify via INPA This will apply to a number of modern BMWs.

As a Bimmer Tech, this is far too much to do.. My Scan tool ( A good scan tool ) does all this is 2 min.. 90AH is not too much, and NEVER use an Autozone battery..
Its f….easyer just to buy 90AH battery, jesus…
If I have an e90 M3 do I choose that ECU under the “engine” and NOT the MSD80?
If I'm not mistaken my E91 320D has had the same battery since new, which means the battery is 8 years aold. It hasn;t given me any trouble until today so I guess I'm going toneed to stump up for a new battery 🙁
Hello, before following your steps on programing and registering the battery i did a full scan using ISTA D on my 135i E82 2008. Have you ever ran into having random comunication errors with diferent ecu's. I say random due to the fact the is I go into the ecu fuctions and i trigger one of the ecu functions most of the time the will comunicate and change in color from red to green. This is not just with one it is ramdom ecu's.
Where do you get the lmf

Hello, I replaced the AGM battery last month, but INPA still shows a value of State of Health (SOH) 0.00. How is the SOH determined and when the value is calculated. Is it normal? Thank you. (replaced the same type battery 900A 90Ah)

Really??? To change a battery i need to do all this crap….what a joke!!
Just bought an E92…first BMW, no wonder BMW drivers are such wankers and dont use their indicators, mad at the complexity of simple things like this and don't want to drain the battery so they have to do shit like this.
I wont be buying another BMW thats for sure, fuck this shit!
Thank you for posting the video; very thorough. One question I have if you have the time to respond:
I have. 2008 e70; changing my battery from 90am acid to 92ah agm. My question is about the correct way to change the trc file, should I enter 92ah_agm, or according to another post: enter it in two lines
92ah
92agm
Or does it matter either way? Thank you in advance if you if you can respond.
I bought a new battery for my 2007 BMW 328i. I am using a non AMG battery. It is a Everstart Maxx -H8 Cold Cranking Amps 900, Cranking Amps 1000. What do I program it at 80 Amps or 90 Amps?
Is there a big difference with the 90 ah and 80 ah
Thanks for this video! I replaced the battery in my E90 last year but it was not charging properly. I had registered it using INPA but thought it was too much hassle to change the aH settings with NCSExpert. I finally did that today with your instructions. The original battery was 91 aH, this one is only 71 aH. Hopefully the revised charging strategy as a result of this change will keep it charged properly.
Thank you soo much for this detailed video. My car battery died out of no where and would not start. After replacing my battery i still had trouble turning my car on at all. Thanks to this video and you. I was able to see where i went wrong with the connections. Advise to all the readers and it might sound silly but make sure that all parts are put back the same way you took it off, i had my positive side not aligned well with the box that comes on top of the battery and that it the reason why it didnt start! I know it sounds silly but i was with out a car for almost a week because of this silly mistake and almost spend a lot of money that i didnt have to!!! Once again VEHICULAR DIY you came through.
2006 325Ci uses what group or size battery?
Car had a temporary Ford Escort battery.
If you don't have software then what can we do after replacing the battery?
You dont need to do that… Mexican engeeners like me.. Are so inteligent and all you need is replace the baterry and use a partucular scanner in 10 minutes and ok
Can you please help setting my INPA to English? When I come to this point everything is in German language… Thanks
