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.
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.
I’m glad I found this cause I just installed a new battery and did not realize I needed to do this. You put together a great instructional video. Thanks for taking the time.
If u can't code it just disconnect the blue cable and it will work
Thanks for taking the time to make these videos, they’re a lot of help!
Excellent write up. THANK YOU ! The only one worth following . With all my searching I wish I had found this first. After my install the Convertible top two fuses blew, which some how is tied into the Trunk and Gas door. so even after replacing the fuse the gas door still would not open. $300. to mechanic I took car to gas station only to have my self stuck with chore of checking all fuses in buried dash fuse box ad dropping one of them. Yes , you do need to re program the computer for new battery. Totally hate people that writing in threads that you do not.
Thanks - very helpful. Especially the bit about the factory trickle charger tap! I was scratching my head on that one!!
Lol I literally spent 30 min trying to figure out where the small connector goes that’s for trickle charging during transport 🤦♂️. I will definitely go to this channel first for my DIYs
Really helpful video - allowed me to finally deal with my dying battery. Thanks
Thanks so much for this video! I a similar new battery and no one could tell me what the AH rating is - until I saw your formula. Excellent detail for the replacement. The one thing that messed me up was that I wasn't able to register the new battery until I turned the steering wheel all the way left and then all the way right - which in turn shut off all of the warning lights on the dash, and then allowed me to register the new battery. I used a Schwaben Scan Tool to reset the battery.
thank you! such a calm way of explaining and getting into the why of the actions as well, much appreciated!
A couple of days ago, I received a BMW with weird problems, they replaced the battery 6 days ago at the dealership but they never registered it and the car voltage was at 15.5v at idle, creating a lot of problems, once y registered everything went fine, great info in this video!
The BMW techs at the dealership: "write that down! write that down!"
Ha! Awesome comment, and based on my past experience, probably mostly true.
Great job on that bro!.... FYI, INPA method is 100% the way its done now. You do not have to go to the extreme and use tool32. Only need to use inpa and it registers, logs it, and resets the computer computer internal timer for power source. Great job man!
Excellent job showing the whole process. Thank you for taking the time to do this. It's interesting to note that you can code 80ah, 90ah, 110ah but not 100ah. I bought a 100ah as an upgrade from my 90ah so I didn't have to actually code the new battery but now I am glad I got to give it a shot. I coded down to 80ah and back to 90ah just to prove I could do it!
Why can't you code 100ah?
you should code for the closest amount that is is still more than your battery. If you code a 100ah battery to 90ah the battery can be undercharged and affect long term life of the battery
This is an amazing guide and well explained. Thank you for taking time to compile this. Very, very much appreciated!
Nop what year was the car ?
Brilliant! Thank you, worked perfectly on my e91 and was able to double check the data as you showed, to prove it had worked!
Thank you so much for your video.. I registered 80ah battery on my e90 325i 👍👍👍
Lots of BMW Enthusiasts are installing lightweight 15-25 lb Anti-Gravity Lithium Batteries. Cost is close to $1000. So light, it can be ground shipped to your door. The BMW AGM Batteries weight 60 lbs and turn a 10 minute battery swap job into a bloody 1 hour saga.
BMW 3/4-series cars can use a H6/H7/H8 Lithium Battery. The battery size is the same, they just get longer 10/12/14 inches. There are several battery cleat holes for long or short batteries. It is a drop in that requires both a battery recoding and a battery reset. Battery capacity ranges from 40 AH, 60 AH, and 80 AH. For cold weather states/countries, you need 60/80 AH batteries.
Excellent video, thank you
Thanks man, best instructional video I found!!! Helped a lot. Thanks again.
dude thank you!
Another great video. Your coding videos are fantastic..!!!
Markstevos Thank you!
You are amazing and this video is incredibly helpful.
I watch your videos all the time. Great stuff! Where did you download INPA from? Would appreciate a if you could share a link.
Great video. Removing the distributor box/BST off of the positive terminal really helps with clearance. One note: don't close the trunk in this state. You'd find out that powering under the hood does not help anymore with opening the trunk, you'd have to reach through the ski pass-through the child safety unlock in the trunk to open it (luckily that doesn't need electric power).
Or use the key and unlock the trunk- get down real low and look up past the license plate to the right. There’s a key hole there and the key that hides in the fob enters in a vertical configuration
Very helpful, Only thing missing is update of VO with new battery specs.
Your a life saver 👍 well explained !!
Excellent Video! very professional and well explained, thank you very much! keep up the good work! appreciate it
Really detail video for newbie bimer like myself. I will try this sometime in future. Thank you very much for providing this video:)👍🏻
What a royal pain & upheaval just to swap a battery on these post 2000 BMWs!
Great video, thank you!
Nice video and very informative...it's a little intimidating for me right now with the coding stuff as I have been driving my 1989 535i for the last 19 years, so this is all new to me. (Just bought a 2008 335XI)..Thanks and well done and I subscribed....

So helpful, thank you! I'm actually looking to replace an AGM battery with a lead acid battery, I've seen people use other tools to tell the car it's switched, I assume there's a way to do that with this method? Thanks!
Awesome thanks! Timer saver!
I feel like a such a tool :D I have E60 with active steering and I was always driving for a while with the innitializing error and it went away in about 15-20 minutes of driving. Never realized I can just train it from max left to max right a few times to get it done and cleared right away :D
If I have an e90 M3 do I choose that ECU under the “engine” and NOT the MSD80?
Great video bro i was wondering what that extra cable in the back was for now i know .
am having some drain problem on 2014 bmw x3 that will help
I enjoy your video's and learning a lot. Here's my problem...I have a 2005 X3 E83 and when I start INPA and then F7 to load E83, then select Engine I can't find any M54. Does this mean that my model of X3 does not require registering. Any help would be greatly appreciated.
Thanks for sharing !!
Probably one of the best videos I have seen on replacing a BMW battery. My trunk looks different. 2011 335i Convertible. Just got a Walmart 95AH AGM. The software does not have 95AH AGM. I guess I will go with 90AH. Not sure if there is a way to update the options. Any ideas?
BMS charges a Lead Acid battery differently than an AGM battery. You need ISTA/P to program the change.
You are the man!
Fist of all congratulations for your channel. I find it really interesting. You explain the matters clearly and makes DIY really easy. Good job.
I have one question regarding register new battery. I tried INPA and I can not find my engine (M57T2) inside engine menu. Anyway my INPA has the option for auto detect engine as first option inside engine options. I have not seen this auto detect option in your INPA. Maybe is because I have a newer version???Althought I can not find my engine do you think i can use auto detect option and I will be able registering my battery using INPA? Hope to receive your opinion. It will be really helpfull.
After my e46 I would love buy an e90 but these vastly more complicated electrics terrify me if something as simple as changing a battery requires as computer programming degree in German! Regardless times change and I'm going to change with them, great video for future reference, thank you.
You have an asmr voice and I like it!
Asmr can go fuck it self
Thank you, worked really good.
Important to note that cable will only work with idrive version 1. Will need a special cable for late 2009+ e90s to code. Cost is around $80 new.
This video is super helpful! You focused on all the right elements to get the job done! Awesome! I had a question: Can I do the NCSexpert coding using DEFAULT profile? I don't get the profile that you show in the video. I have recoded DSC to default setting using the DEFAULT profile earlier and it worked smooth, was doing that while installing a replacement SZL unit. Should also tell you, I have registered the new battery using ISTA which updates the Date and Time as part of the registration so its really smooth, however, the AH is lower on the new battery. For that, Ista directs you to ISTA P which I do not have. So I thought I'd follow your video but I've never created a MAN file or tried to code it into CAS, wondering if it's safe to do with DEFAULT profile. Thoughts?
This is a great video, I am a first-timer of INPA user, downloaded the software and installed it. The only issue was with the drivers which I downloaded from FTDI website and it worked. Both Battery and Ignition are on and I could able to read some info by using INPA. However, the main problem which I am having is everything in INPA is in German whereas in this video in English. Do I need to change any settings? Thanks a lot.
Can you do the same procedure in a 2011 BMW 335i xDrive e92
Best video ever bro
Legend, thanks!
great video bro
Thanks man
Thanks. The process worked for me. One problem i ran into was that it wouldn't accept the registering of my aftermarket 100ah battery.
NCS throws an error message when you try to register 100ah. It accepts 90 or 110 though, so i chose 90ah as a workaround. Not a perfect solution, but it was a workaround which i picked up in a BMW forum. The only alternative would have been to buy an 80 or 90 or 110ah battery.
Np, glad you found it helpful. Yeah it only has options for batteries that were offered from the factory. Your best bet is to find a battery with a similar rating.
I have the same problem. Why not a 100Ah doesn't make sense.
I have an error code. What do I do now?
Grate video.. thank you..
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.
Thanks!
Hello, great step by step videos, I'm switching from lead to agm, where would the _AGM need to be expressed? after the class of battery or after the ah? Thanks you.
Hey I have another video on my channel for when I switched form AGM to lead acid on my X5, check that out.
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?
Thanks for the video, excellent tutorial, but.... I did all the things as you've shown and when I check in INPA the battery capacity doesn't change. The old one was 85ah non-AGM and its coded 80ah. My new one is 95ah non-AGM and I tried like 4 or 5 times everything goes smooth like butter but the Ah capacity does not change at all in INPA and keeps showing 80AH registered. I'm checking the MAN file couple of times before I code it and still... I'm not sure what else I need to do. If someone has any advice would be amazing. Thanks once again!
Good video... Can you tell me if I Need to do this procedure on a 2001 E38? Any information would be greatly appreciated thanks
Thanks a lot
First off let me thank you for all the videos you provide, a real blessing for us DIY's.
I have a E93 2008 335i so we have very similar cars and a lot of your videos apply to my car and I plan on keeping it around a while so I consider your channel a real treasure. But alas to my question for you, I searched over the titles of all your videos looking for information on coding out the CIC Legal Disclaimer on the startup screen but couldn't find any information on your site. Have you ever done this and can you point me in the right direction?
PS, I have used NCS Expert for coding in the past so I am vaguely familiar with using this tool. So I am thinking I would have to edit a specific ECU to code out the CIC Legal Disclaimer?
Thank you, glad you found the channel helpful. I haven't actually done it on my cars but that's a good suggestions. I'll do it and put up a video.
I have a 2011 328i coupe. Twice now there has been a lot of water found in the battery compartment. Two years ago I had to replace starter, battery and the passenger side wiring harness for $2000.00 at an independent. Last week they found more water and got the water out of the compartment before major problems. There is a vent it seems on the right side of the compartment. Is the water getting in there in rainy weather? I avoid deep standing water. Could there be broken welds? There car had a minor rear end fender bender while a courtesy car with the dealer. I will be going to them shortly with bills and photos. Any thoughts?
Another great video. You have inspired me to buy a high milage E93 and be able to keep the maintenance up without having to spend a fortune. Question though unrelated to this. I noticed you had TPMS light that came on. Do you have or plan on doing TPMS /RDC troubleshooting DIY vid?
Hey thanks. So far I've been lucky and haven't had any issues with my TPMS system. I'll be sure to document it if I encounter any issues.
amazing!. Thanks!
hanizz2 Np!
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?
great video thanks a lot saved a lot of hassle and you said what that trickle charge cable is for
+Vehicular day.On tool32 where did you get that MSD80.PRG from.
i replaced my Battery yesterday on my 2008 Audi A6 it was a Varta 110AH and it was still the ORIGINAL 14 years old !!! i bought a 90AH instead of the 110AH but i guess its good enough. I let the engine run while switching over the battery, so i didn't had to do any "re-programming"
Question : I'm changing BMW original battery with 80 Ah to a new one 70Ah. Should it be enough register with carly or do I need some decoding ?
Anyone knows what is that black cable that goes in with a connector to the positive side? Thanks for the excellent video btw!!!!!!
Your a bad ass hacker and a tech great video hard part is finding a tech like you
Awesome job on the video! very complete and informative. I have been looking for the INPA software, could you give me a hint where I can download it from. Thx!
Thanks, did you try the links in the video description yet?
Yea, I didn't even know this was an issue, Never had to do on my e-46? Anyway, as all stated this instructional video is the shit, your vids are the BEST on this subject, thanks dude (318i e90 2012)
The latest BMW E/F Platform AGM Battery P/N in 2020-2024 is now 92 AH/850 CCA and costs about $250. You can't select 92 AH when recoding, so pick 90 AH. Early 2000s BMW Battery Capacities were either 90 AH or 105 AH.
I appreciate you
Hi great video,, what kind of software are you using, and where can i buy it, thanks.
I have INPA etc installed from earlier but I have never used it to code. Only for reading errors. When i run NCS and "load profile" I only get the following options: "Default profile", "Manipulation", "Factory coding" and "NCS Dummy Profile". Can I use one of them, or do I have to get the Revtor profile into my NCS in some way?
I just want to confirm so if I got a battery of the same size for my 2009 135i a 94R H7 and it has the same Reserve Capacity I can just register without needing to change the AH? Thanks.
Hi! On my NSC expert I don't have this Revtor's NCS Expert profile. I have other profiles but which one can i use? I have try some of them but after export in my .TRC file there is no line that shows Klasse Battery?! Am i need to write it down on hand or that's because the file was not exported correctly? What should do? Were could I find that Revtor's NCS profile?
Always been amized about your diys and now I cahged my battery, it did not go well..damn I didnt't get car slepp enough and lost my power windows, lights only head lights seem to work, no turning signal, I have not covered programn on my inpa to get it from there, what I should do now, also interior lights are gone damn me if this was only let car asleep for while before installiton. could oyu help me out little? I couldn't find ncexpert same issues that you have, I was little lost, anyway your diys are best always to see all details about what are you doing learn a lot but now I got something wrong a lot. Thanks for this all videos in here on your channel!
Did exactly according this detailed manual. Unfortunately INPA still showing 90Ah battery! Any advice please?
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)
very informative, thank you
Hi! thanks for the video. One question: Why do we need a laptop specifically just for the car?
Good question!! I like to see the response, please. To know the proper procedure. Since where I live there is no electromechanic and to do all the coding I have to put the car in a boat to take it to another island to do that. Understand? Some places on the World are different and not too easy to obtain all the things are needed like regular people do. Hope U understand!!! Thank you friends!!!
I did this previously, and it worked perfectly fine. But then somehow my car started acting again like it did before I coded and registered the battery, and now Impa will NOT give me the two black dots, and NCSExpert gives me an error when I try to make a change. Why does this not work suddenly. One of them gives me a VIN error, but it's the same VIN and same car as before.
Worked great, thank you so much!
INPA register seemed to work for me too. I went and did it through tool32 anyway, then for some reason did it in INPA again. Now i've coded the same mileage to my 2nd, 3rd, and 4th battery registration... does this matter?
Np! That won't matter.
Thank you for the awesome video. The autocrat silver battery you are replacing says 850cca, so shouldn't be 825/7.25= 113Ah should be programming in NCSEXPRT instead of 85aH you put there?.Plase let me know
Reply from ADVANCED AUTO PARTS......Steve from AAP said:
"Hi JACOB, I'm glad to assist you! This AutoCraft Silver Battery - Part # 93-1 has an amp hour rating of 91 amp hours at 25 amps."
With all that computer control for the state of the battery you would think you would get more than 5 years out of it. My 2001 e39 still has its original battery. Yes 16 years! I kid you not. Its only now getting to the point I should replace it, but it still starts and holds enough charge to stand for a week. But I've always used a battery conditioning charger to top it up every few months.
Wow that's impressive, yeah there are so many computers on the car that you're lucky to get 6 years out of a battery on newer BMWs.
One question I got... I just change my battery from 80ah to 85ah but can't register that so what to do? Leave it on 80ah?
Just wanted to say thank you for sharing this with us, your video has helped me a lot! I've just replaced the battery in my 2009 e92 330d and everything went smoothly. I still had an original battery from BMW which was a 90ah AGM battery and I've replaced it with a 95ah AGM battery. Even though the original battery was only 90ah INPA was showing it as 91ah, NCSExpert was set to 90ah and it wouldn't accept a higher value, so I've just registered the battery change and left the ah value as it's not a big difference. Have you experienced something similar?
BTW, the INPA method of registering battery change worked for me as well.
Glad you found it helpful! Yeah unless the computer has that exact value stored as an option it won't accept the a random value, it will round to the nearest known value. You're not too far off so I wouldn't worry.
Is it okay to buy regular 95ah autozone battery to replace my 90ah BMW battery. Do you recommend any brand in particular ?
what size was the battery and how much voltage
Question: @ time 27:50 is he saying msD80.prg or msV80.prg? I have a 328i E93 should I be using the V or D 70 instead of the 80 as mentioned in the video?
Thanks for the INPA, NCS expert and EDBIAS 32 demo. I need to really study up on that. The problem I have seen online is that the threads start 10 years ago so it seems one has to learn how it once was accomplished then, go through all the subsequent changes, then arrive at the current level and learn that while for getting every thing else which one has spent days learning but is now obsolete.
It would be more helpful to be able to engage a current tutorial, and just learn what is current. Does such a site exist?
Thanks.
Oh. if I remember my German correctly, lesen (to read) is pronounced lay - zin. The s has z overtone, if that makes sense. Are you in Austin?
The newer software is ISTA, I'm planning on doing a video on that soon as my new F15 X5 will require it.
Do you think it is necessary to code battery even if it has exactly the same specs with the original one.
If I install an aftermarket battery like interstate AGM battery and register it, will it run normal as in having the dealer install their original battery?
Does registering the new battery with Tool 32 after doing it through INPA and NCS Expert do anything? Or will INPA and NCS Expert be sufficient since there is no difference once you check the status on INPA after using Tool32?
If anyone has any info to help me with. I’ve been working on my 2009 328i. At first I thought it was just the battery because I had to jump it a few times and it would turn on. Then one day I went to the lake and it didn’t want to turn on period. The tow truck worker said that sounds like the starter. So I changed the starter, it worked for about 4-5 starts. Now it’s doing the same thing before I changed out the starter. Just making a click noise but it won’t turn on again. Should I be worried that it might just be the batter terminal or terminals? Please any help, thank you!
Hi: Very much appreciate your DIY videos. Quick question re battery replacement in my 2011 e90 335d. I am thinking about replacing the dying lead acid with an AGM and have the Foxwell NT510 scanner/coder that allows registration and recoding for battery type. My question: does the code exist within the 2011 e90 to accommodate AGM charging? Thanks.. -Robert.
Robert Krikorian Hi, glad to hear that. Yes your car would support an AGM charging profile.
