BMW E90 3 Series Battery Replacement With Registration & Coding. Switch From 90 AH to 80 AH

[@getlosttogetfound986]

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.

[@joaquinvasquez7923]

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!

[@vikneswarankanapathi6465]

This is an amazing guide and well explained. Thank you for taking time to compile this. Very, very much appreciated!

[@CanBus-li5ky]

Nop what year was the car ?

[@brettallen7809]

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.

[@moreno487]

If u can't code it just disconnect the blue cable and it will work

[@SamplesDan]

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

[@RodroRepara]

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!

[@theoilchanger]

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!

[@husamhanif1848]

Why can't you code 100ah?

[@cxt7181]

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

[@jw6188]

The BMW techs at the dealership: "write that down! write that down!"

[@rihamy2nd]

Ha! Awesome comment, and based on my past experience, probably mostly true.

[@augustovazquez2641]

Thanks for taking the time to make these videos, they’re a lot of help!

[@tedstout634]

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.

[@simonlariviere9855]

Brilliant! Thank you, worked perfectly on my e91 and was able to double check the data as you showed, to prove it had worked!

[@boost4fun]

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.

[@rianhart4143]

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.

[@annaifos]

thank you! such a calm way of explaining and getting into the why of the actions as well, much appreciated!

[@nycshelbygt500]

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.

[@Stepica]

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

[@frankgarcia5260]

Excellent Video! very professional and well explained, thank you very much! keep up the good work! appreciate it

[@BlueHelm]

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).

[@soburnedout]

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

[@tinchos4400]

Thanks man, best instructional video I found!!! Helped a lot. Thanks again.

Really detail video for newbie bimer like myself. I will try this sometime in future. Thank you very much for providing this video:)👍🏻

[@Luton-Mick]

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.

[@ThreeFiddy1701]

What a royal pain & upheaval just to swap a battery on these post 2000 BMWs!

[@frankw9836]

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"

[@Houstnwehavuhoh]

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!

[@LOOKING_BEYOND]

Your a life saver 👍 well explained !!

[@loopster40]

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?

[@nycshelbygt500]

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.

[@rjdom]

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)

[@Moxking]

Very helpful, Only thing missing is update of VO with new battery specs.

[@pkelly20091]

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.

[@VehicularDIY]

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.

[@slot1999]

I have the same problem. Why not a 100Ah doesn't make sense.

[@husamhanif1848]

I have an error code. What do I do now?

[@HeirApparent]

So, at the 25:00 mark, you say if someone is installing an AGM battery, they need to "write an underscore AGM", but you don't clarify exactly how... is it XXah_agm, or XXah_AGM, simply XX_agm or XX_AGM, or something else? Thanks.

[@HeirApparent]

OK... 26 minutes into another one of your videos on another one of your cars where you're changing from an AGM to a lead acid, NCS Expert shows the answer I need... XXah_agm. You're welcome, and thanks! ;-)

If I have an e90 M3 do I choose that ECU under the “engine” and NOT the MSD80?

[@AquaStevae]

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.

Ah, I always got that spark connecting negative, thought I did something wrong. Finally some closure

[@machismo53]

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.

[@drdeni]

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?

[@MrJpxavier]

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?

[@jahovahackenheimer]

I put in a 900CCA H8 battery. This roughly translates to 124Ah. NCS Expert will not accept this value. It says faulty code. I also tried 120Ah and got the same result. Great video as always!

[@slot1999]

i think i have the same error when I change the value to 100Ah and press execute job and error pops up. Did you fix this?

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!!!

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.

[@luesugi968]

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?

[@regimantas6433]

Thank you, worked really good.

[@almightymuma4330]

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!

[@Lagos08]

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 ?

[@DrongM]

Did exactly according this detailed manual. Unfortunately INPA still showing 90Ah battery! Any advice please?

[@rudijohnson529]

What size is the battery supposed to be? I put in a 668 but having problems, as soon as I try press start it kills all my electronics on car, cars completely dead my lights everything will switch off

[@shaazy]

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?

[@slengoslengaw8510]

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?

[@RayRx84]

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.

[@utube4greenfuture]

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.

[@ruan800]

Awesome thanks! Timer saver!

[@davidchiasson4262]

Very informative video. But you said that the specs of the 2 battery are close so normally you wouldn't bother register the new one. What would be the limit that you would consider registering the new battery? I just bought a 140 R/C battery so: 140/2 +16 = 86AH. Since OEM is 90AH, should i be ok if a reset it to a new one without changing the AH in the ecu?

[@VehicularDIY]

No regardless you need to register a new battery, but with regards to telling the computer what the AH rating is that only apply if there is a change of more than about 5AH.

[@gmascagni]

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.

[@efraindiaz26]

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.

[@eman0828]

Do realize these Chinese knock junk can be potentially dangerous for your cars electrical system. These cables are generally of lower quality as you can brick and short out computers. You can really fuck things up. I would never trust them as I always buy the real thing from the OE suppler. Drew Technologies that makes Mongoose partnered with Toyota, GM, Honda, BMW.. that provides you will with high quality programmers at an affordable price. These diagnostic programs works best when they are not pirated.

[@goognamgoognw6637]

Eman it's a double edged sword. You buy a cheap chinese cable it might work and save you money, or you buy one of those stupid tuner cable rip off that charge you 5X--10X for the same chinese cable after they figured out that pin X needs to be jumped to pinY or some other trivial hack for it to work in all cases, then they put a 5 cent printed sticker on it and fools think it is higher quality. The only difference is they figured it out and tested it, not quality.

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?

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, first of all, thank you for very informative guide, just changed and registered my battery according to your tutorial. But I still have few open questions. I hope you could help me. I changed my battery from 80Ah bmw original to 80Ah Varta AGM. So I checked trough NCS Expert and there it was just 80Ah, so what is the correct order to add agm next to it? should it say 80ah_agm ? Or can I leave it just as 80ah. Second question would be you load MSD80.prg with tool32, but my engine is M47TU2 (couldn't find it there), is it ok to load it with MSD80.prg or I should load different? Thank you in advance!

I've back logged a few of your older videos as you mentioned talking a bit about setting up inpa etc. on an old lap top. And you mention in this video about dedicating an older laptop specifically to coding your bmw. My question is why exactly do you recommend that out of curiosity? Just wondering why I can't just set it up on my current use laptop or what the issues could be with doing so.

[@VehicularDIY]

You could try but you'd have to start with a clean install and there is a good chance that some small nuance setting can screw up the software with normal use.

[@Feenyxxx95]

Vehicular DIY I started on a fresh install and everything worked flawlessly. I was able to code the car and register the battery etc. I'm just wondering what problems normal use of this laptop would/could cause in the future.

[@VehicularDIY]

Great to hear. The recommendation mostly comes from the fact that most users won't want to wipe their main laptop clean. I'd be worried about com port setting etc getting screwed up with driver update etc.

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 :(

[@husamhanif1848]

I received an error code. How do I return everything back to normal? Before I did this? Is there any way?

[@filterscanada8232]

[@nck067]

I installed the Ecu cooling fan in my 318i, do I need to coding it?

[@robertstorozyk2431]

I have a 2008 328i, and I'm getting ERROR_ECU_CONDITIONS_NOT_CORRECT_OR_REQUEST_SEQUENCE_ERROR with both INPA and Tool32 when trying to register the battery. I bought H8 battery from Costco. Any idea what might be the issue? I haven't found any solutions out there yet.

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.
