I just did mine today. Thanks for the thorough install helped out a lot. I tell you what taking out and putting in a 60lb battery in that tight of a space while keeping the wires out of the way was a pain in the ass.
Glad it helped! And yes, this is by far the largest battery I've seen in an automobile (car). Guess someone can skip the gym for a few days after working on it. 😀
@@CoderMan I was a bit winded afterwards tbh. 🤣
Yeah I had to one leg squat in my trunk to get that battery in and out. It’s freaking heavy for such a weird angle
Amazing video! I just changed battery on my BMW 328i. Dealer was asking $450, I got it done for $200. Thank you brother. Keep up the good work :)
Awesome! Glad it helped.
Thx this helps
Did you have to code it ?
Great video man! Just changed 11 year old factory original battery in e92 335is . Video was perfect .👍
Awesome! Glad it helped.
Great job on the video! I was able to change out the battery on my 2013 E92. Thanks dude. Keep up the good work!
Thank you! What spec M3 do you have?
@@CoderMan Actually it's just a 328i XDrive coupe (with M Sport package).
Hey any issues without registering?
@@rengokusats No I didnt have any issues. Good luck to you.
I wound up having to replace my battery, my car sits on a tender more days than not lately.
I bought one from Autozone, Duralast Platinum AGM Battery H8-AGM Group Size 49 900 CCA.
I do have a handheld Foxwell 510 scanner that I used to register it, and set the steering wheel sensor.
Thank you for the tutorial, I appreciate you taking the time to do it.
Thanks! Glad you got it working.
What’s the steps of registering the battery? Is setting the steering wheel sensor a part of changing battery process?
Helpful video. Just completed the same task. The red o-ring on the bolt of the back battery bracket fell off, you can see it in 5:53. Confirmed where it was supposed to go when was trying to figure where it came from! Thanks.
Glad it helped!
Great video. I just installed a new duralast platinum H8-AGM. Getting the right side of the distribution part loose was a royal pain. I had to really torque the part to pry it loose. I was afraid it was going to break and that alone took 15 minutes. Also, the bracket to hold the battery in place was also a royal pain. There is limited room to line up the bracket. I used my extension and taped the screw to the socket. Also, the extension was on a little swivel which helped screw into the bracket. The alarm did go off when I removed the negative. I just used the key it stopped. I did not lose my "touch" settings on the radio. I turned the car on, and I did have to set the clock as described. No errors and all is good!
Awesome, glad to hear it helped. The car computer does keep some settings but like most, the radio (and seat) presets are usually lost. The alarm going off is actually a good thing, well not for your neighbors lol
Hey did u have to code the battery to the car when u used ur duralast
Nice video thank you, it will save me a lot of time when replacing the battery on my son's 3 series later this week. I am pretty sure the 'bracket' is actually a brace to stop the battery from moving or flying though the air in the event of an impact/crash? It also obviously doubles as some kind of support for the boot (trunk!) trim etc
You’re 100% correct. That battery is heavy and any shifting could do damage to it and the car. Not to mention the electrical components on top of the battery. Glad to video helped!
Love your video keep more post going I’ve got a m3 and my warning lights are on
Thanks! What warning lights are on?
As some have commented below, you will need to register the battery, if the same specifications, or code the battery if they are materially different. From homework, the 90, 92, or 95amp, as long as same CCA and staying with AGM battery, is same specification. I used Bimmerlink via OBD Vlink dongle to register the battery, was the simplest and most affordable combination -- although it was sensitive to being in ignition position 2 (so engine not running, but dash and interior fans on).
Finally regarding the bracket over the battery, I think is safety device mainly, obviously holds the battery in place, but suspect is if the vehicle is in a rollover, that it has better chance of holding it relatively in place.
Good note on the battery bracket, I also appreciate the insight provided for others.
Welcome back!
Thanks! Summer has been crazy, hoping to release videos more frequently now!
thank you for making this video. excellent instructions.
Happy to help! Thanks for letting me know.
Excellent video. Keep up the good work.🚗
Thanks! Appreciate it!
Good use of the camera and a good video thank you
Thank you, it seems to have helped a bunch of viewers which makes me happy!
Hey thanks for the video, I am about to do the same to my 2011 335D. I was concerned about the registering of the battery and setting the amp hours. There is another video on here that the guy uses a snap on diagnostic tool to set the amp hours and register the battery. Since you replaced the original battery, I am also replacing the original battery. Did you get a battery that was exactly the same specs? If so which one did you get so I can follow suit? It would make sense that if the specs of the battery do not change that there would be no need to register the battery, etc. Also what issues were you having with your car that lead you to change the battery?
I got a duralast battery, exact spec as the stock one. I was getting charge errors when I would start the car. Thought it was electrical components and decided to swap the battery (it was original from 2011). Once I swapped all the issues went away.
Registration with the car's OBD is required on all new batteries, coding is only required if the new battery is of different specs than the OEM you just removed.
That's how I know it as well.
Great video it helped me out thank you 😊🙏
Awesome, glad it helped!
great job and thank you for sharing
Happy to help!
Well done! Thank you.

Super helpful! Cheers mate
Glad it helped!
FYI, the yellow/black twisted pair cable near the positive terminal is used by the ECU to trigger a tiny explosive to break off the starter to battery connectivity in case of collision when airbags are deployed.
When that happens, the radio, lighting, etc will still work because the distribution block to battery connectivity is still intact. However you just can't start the engine. Don't ask me how I know these...
Well that’s something I never knew or even heard of. Makes sense from a safety standpoint. Sucks you had to learn about it firsthand. Thank you for sharing with the community though.
Really liked this video
Glad you liked it. I have a bunch more on BMW, please consider subscribing.
I replaced the battery then like a few hours later the battery symbol popped up ??? does that mean that the alternator is not charging it? any help
Did you use a different battery? You may need to code it, otherwise the car may not use it properly. Do you have a code reader? You may have a loose wire as well.
Great video. Thanks
You are welcome!
Hi, I've got aquestion about changing my E90 battery. The current battery in the car is a 12v 90ah 900a 900ccc. A local parts store recommends one of it's own brand battery (AGM 019 stop/start 95ah 850ccc). Will putting in that battery with slightly different specs damage anything in the car?
That’s a tough one, everything I read says to use the exact spec. I would be sure the shop is correct. This car is fickle with batteries, from my experience.
You can use different battery you just need to “code it” tell the car you have a standard non agm battery or vice versa. You would also need to tell the car the different parameters..92ah to 90ah or whatever battery yours is. You would also need to register the battery and tell the car it got a new battery to charge it like a new battery
Thank you for the video. On my e90 2009 the cable from the main positive terminal it is not connected anywhere, not sure if thats what causes the car not to start or even crank.
I would venture a guess of yes that would certainly cause a problem.
Thank you for this, it is really helpful. Do I need to only use an original BMW battery? what are the alternatives. Thanks again
You can use an aftermarket, like I did. Provided all of the specifications are the same. Which one to use will depend on your car and current battery to match.
I have heard that you need to reset or code the ECU after battery change in BMW cars, and in this car you didn't do that, does this car require that or we can just swap in a new battery without any resetting?
If it's an exact battery you don't have to code it in most cases. I would do it given the additional info I learned but it's not technically required.
@@CoderMan thanks!
Hey great video, but my brake hose wasn’t connected to anything either, could you possibly make a video or let me know where that is supposed to go
Brake hose in the engine bay or?
I have a F82 2015 BMW M4 that uses a lithium ion battery. Every time I start the car I get “increased battery discharge” I contacted my local BMW dealer and some tuner shops and they all tried to charge me $1900+ for the new lithium ion battery. That is just crazy stupid... I am wondering if I can put in a normal battery that matches all the specs to my oem battery in the car. Please help me out
Wow, that is an insane cost. I am not sure if you can swap batteries but I would hit up the M3Post forums as someone else might have done it.
The negative terminal point is that light grey or metal stick to the left of the coolant reservoir sticking out the frame.
Interesting, I hadn't known about that.
I know that I am a little late to this discussion, but I need to replace my battery. It suddenly died this morning. I jumped it and it drove me 100 miles. Then I went to Advanced auto parts to see if it was the battery or anything else, they told me it was the battery. I had to jump start the car again. I just spoke to my local BMW dealer and they told me that if you change the battery with the exact same one, you don’t have to code it. He told me that for my specific battery, 12V 90AH 720A I didn’t have to do anything. It’s for a 2011 328i Xdrive. Surprisingly enough the battery is just $154 at my local BMW dealer.
Thank you and I hope this helps. I’ll be getting my battery and installing it later.
Hope it works out. Let us know how it goes.
CoderMan It works great. No problems at all.
I also have a 2011 bmw 328i series 3 and I’m having trouble every day with my battery. I have to jump start it with my portable jumper this been going on since late march and I purchased a new battery at Walmart n still I have problems with my battery I noticed that my drain plug is broken is there any advise you can give I will truly appreciate it oh also the monitor in my days battery decrease drain
My first thought would be parasitic draw (any aftermarket stuff installed)?
just wondering when i remove the terminals on the battery my car start alarming and do you what caused it?
Alarmed cars have failsafes to go off when the battery is disconnected. Im not sure if it’s an OEM alarm or aftermarket. You could pull the fuse or let it go off and then work on the car. You’ll get weird looks from passerby’s but should be fine.
Thank you for the steps but did not see how you put the plate back in place and can we get information on the battery what size is it a H8 or H9?
I swapped for an exact type/size/rating. Though i don't remember offhand which one I used and have since traded the car in for the GT4.
Thank you for making this video! It just saved my 18 year old from me yelling uncontrollably at him! LOL
You're welcome! Glad it helped.
So do you have to update computer after battery swap.? And what happens if you don't?
I would, look into Carly.
I have a 2008 bmw 328xi and it needs a battery can I get away with just changing it out with a different one and not reprogramming?
I am not sure on that model. Since swapping this I’ve been getting conflicting reports. I would check the forums for that model to be sure.
CoderMan well I did it and so far it just threw a 4x4 code which was cleared my turning the steering wheel, no problems so far
Great video Thank you ! but I have one question, you did not put the gray vent hose back...it looked it was already not attached to anything in your car, was that normal?
I'm not sure since it's been so long but I believe everything was connected properly.
@@CoderMan Your video helped me a lot in changing my car battery, after a lot of research I found that the gray hose should be attached to a tiny hole or to another elbow bend joint similar to the one pugged into the battery vent, it varies depending on car models, it's very important for that to be connected to your car because it leads toxic chemicals outside your car since the battery is located inside the car
This is all new to me. UK owner here.
My 2009 batt lasted long its on its last leg.
Start stop is turned off idrive wont let it work and music playlist is all blank names files.
In the winter the car turns off the heated seats and rear heated window and wing mirrors lol since the battery is starting to die slowly.
Problem i had was trying to find the right spec battery.
Mine is 90ah 900cc agm
New one is 105ah 950cc agm
Going to fit it on but not sure on what i need to do regarding coding. Since this battery is higher.
Sounds like a bad battery, hopefully a replacement works for you.
Awesome thank you!
Happy to help!
Hi I got the passenger restraint malfunction light came on any clue how to fix this?
That's hard to say. I would have the belts checked and the cabling to ensure it's all working properly.
Did u do the battery register? If so, how? Or do I have to take it to a shop?
Depends on the battery, look into the Carly app if you want to do it yourself.
Hey ! Do you know a lot about bmws ?? I got a 325xi 2002 all wheel drive it’s making a scraping noise , people are saying transfer case I have no clue
I don't know a ton about them, but would defer to the forums and/or locals.
I got to register the battery o not and then I have the hazard light blinking I don't know why
Sorry, are you saying you did or didn't register the battery for the hazard lights to be blinking?
I need help on that is make me stress some time s it can cause the incident from in caming vehicle please answer me I need help
Apologies, I cannot help with this. I would recommend you contact a local mechanic, lots of possible options for the vehicle not going into gear. Could be the gear selector, transmission, gear oil, etc...
So I replaced my battery and now for some reason both blinkers won't automatically turn off after completing a turn. Any idea on this?
That is very strange, did you check your fuses?
@@CoderMan going to have to dig into that. It is weird man and annoying. Thanks for the tip
Any updates since you did not register the battery? I need to replace my battery as well. Dealership wanted $580 to replace it, would rather do it myself and save a few hundred.
Absolutely zero issues since I installed. I did not need to code a thing, on my 2011 (build date 2010) M3. As you can see from the video it’s simple enough.
Another video showed that you have to reset the battery in the ECU so that it doesn't attempt to over charge the battery. Do you know if the battery dying clears ECU mod I have?
The battery dying should not alter the ECU, unless it broke.
@@CoderMan thabks for responding. Do I need to reset a battery setting in the ecu or whatever by odb program? I bought a non bmw battery but unsure it will properly be regulated without coding tool.
If you used a different battery I recommend you use the Carly app to program it.
I thought you were going to explain how to register the new battery using INPA / ISTA . I currently have the low battery warning when I shut the car off.
if you want to register the battery check out the Carly app. I didn’t have to register mine.
Hey coderman, looks like u saved some bucks and went w the Duralast to replace the BMW battery. So don’t you need to Register the new battery? Or is that not necessary??
It is necessary. The alternator can overcharge the battery without it
The consensus is maybe? I haven’t had any issues yet, but the amp/rating is the key to match. BMW of course does not actually make the batteries.
@@CoderMan When I went to the bmw dealership they told me that I needed a bmw specific battery for them to register it. But idk i haven't had any issues as well and i used the same battery as you
Anthony DeLuca You are not required to use the BMW battery. The dealer just wants to sell you a $300 battery... :(
Thanks for the video? Did you not do any coding after installing it?
No, wasn't required.
how did you know the battery needed replacing? i have a 2010 328i 6Mt and every bit of an electronic component inside the cabin is going haywire. i bought a duralast platinum hoping that will do the trick, last time a battery was registered was at 55k miles and i’m at 180 now! lol not sure if that’s correct, voltage was also at 11.35v when resting without the car on should be at 12.5 to 12.6 figuring it’s a dead/weak cell in the battery. i’ll come back with an update soon, made the install looks easy brother
My first indicator was a charging error. Then I had one instance where the M3 wouldn't start. I would say electrical hiccups are a good indicator. Glad the video was helpful!
How has that battery treated you since making this video? I just bought the same one
No issues while I owned the car. New owner hasn't had any issues that I'm aware of either.
If I put a new battery on my e90 do I have to register it I noticed you didn’t. Everyone I have talked to has told me they need to install new battery so around 150 for new battery plus the registration of the battery can I just swap it out and be done with it or is it really critical to register it don’t wanna end up with more problems down the line like electrical problems or something any feedback helps thanks
I didn't register it, but if you see in the comments its divided whether its needed. I found if its the exact same tech specs on the battery you'll be fine, but I wouldn't skip it just to save a couple bucks.. in my opinion.
Hey man thanks for the reply your a great help Subscribed. your channel is very informative have a blessed day and thanks again 👍🏼
@@mrk_deville6436 Thank you so much!!
I was doing research and why does it say we have to reprogram the battery when we install a new one ?
So some people have said it needs to be done. However at this point I would do it for peace of mind.
I have a question what’s the black and yellow wire connecting to the battery for? Mine is hanging there.
I actually don't know. I'm guessing an accessory wire.
@@CoderMan thanks. I’m gonna google for answers
@@bounyava I got me curious too. Found this info, seems likely. It's likely the BST (battery safety terminal), where in the case an accident is occurred, there is a little charge inside the terminal that explodes to push out the battery terminal, disconnecting it.
Morning sir am chatting from Namibia my BMW e90 petrol some times don't want to move even I put gear I press the acereraite but still hider
Appreciate you reaching out, wish I could help more. See first comment for some info.
Hi I will be replacing my battery tomorrow. Unsure if it's the same specs as the one I have but could possibly be also as the one I have is all in chinese. if it's not will I need to have the new battery programmed with my car? I think that makes sense lol
It will depend on the battery model and specs. It certainly doesn't hurt to program the battery for peace of mind, in this case.
I have BMW X3 2013 I have problem wen I lock my car alarm keep go off what should I have to do change the battery
Hard to say 100% but that does sound like an undercharged or faulty battery. If you scan the ODB do you get any fault codes?
ye may mackenik told mi problem is in battery voltage
Can you tell me how much is the new bettery BMW x3 2013 xdrive 28i
@@ahmedaamir3188 I don't know offhand. The OEM M3 battery was around $300 from the dealership. Check with a 3rd party shop for a comparable battery.
So h6 or agm?
Checked in Costco, they have both, agm is almost doubled,
I can't say, you'd need to match what your car currently has (or the owners manual)
Do you have to register the new battery?
Not required if the specs and model are the same. Doesn't hurt to though.
Installing my new battery today. I think getting that small bracket (near the tail light side) that holds the battery from moving around is going to be tough to get that bolt started in the hole. Some models, I've noticed, have an extended long rod to pilot the bolt into the hole. I am not sure how important it is to register the batter, but I see many battery installs where they use a scanner to tell the car it's a new battery. Be well.

Hopefully it's not a tough install. That bolt should have a rod or guide to help you.
@@CoderMan Thanks. I got the new battery installed, but car still won't turn over. Now it gets complicated. Any ideas? Thanks.
phil
@@uptownphotography Sorry I missed your follow up. Did you get the car running? I was going to ask if you tightened the battery terminal wires.
@@CoderMan No worries on missing my comment.
Yes. The car is now running. After days of troubleshooting, installing a new battery and buying a relay that goes bad sometimes on the fuse box it turns out the braided grounding strap/cable that goes from the body to the engine was corroded and not grounding the starter.
My mechanic (when I called him) said could be the starter, but try this first as grounding straps go bad over time. He told me to take a jumper cable and put one end on the ground post on the body and take the other end and put it on something metal on the engine and and see if she turns over and starts. And it did!
The strap on my 2008 E90 is tough to get to, so I had him do it, but thankfully it was not the starter. Who would have thought just a ground wire went bad. Hope this info helps someone with a similar problem with a BMW car not turning over.
Phil
NYC Area
@@uptownphotography Thank you for sharing and glad you got it working! I ended up having the ground strap go bad it seems to be exposed to the elements. Over time it gets corroded and can break down. Glad it was a simple fix and not the starter.
As much as I enjoy driving this car, this is what drives me to hatred with it. Everything is soo complex for no reason when it could be soo much more simple. I was following everything on this video up until the last part where I can’t find the bottom pin that’s keeping it in place
If memory serves, the location of that pin is below the battery in the tray. I agree its little things that make me dislike really fun cars.
I read that the metal bracket is for roll-over protection.
That makes a lot of sense.
Hey Coderman, did you code your battery ? Yours looks like it has IBS.
I did not. I would now.
@@CoderMan you should add a descrition to your video.
I have a 09 e92 m3 and my battery light turned on the next day the car died on me any idea on wether i should change the battery or the alternator?
I’m guessing dead battery. You can’t jump this car like normal, so it’s safer to buy a new battery and/or have a tech look at it.
I just found out i got a baf alternator
Did it die on you while it was running?
I got a jump and it would run for a second then cut off
Woke up this morning to a dead battery idk how I’m rushing to try and make it to work , luckily a neighbor was gonna jump start me I figured cool the battery is in the back I open the back and I’m like 🥴 it’s a bmw of course it’s not easy to get to it 5 mins trying to take it off I’m like nvm and said thanks to my kind neighbor for waiting for me lol 🤣🤣🤣 so here I am learning how to take everything off
Yah BMW really doesn't make it easy. I will mention there is a jump point under the hood I later found out about... after I sold the car!
Nice battery installation! Could you give the battery spec (manufacturer, model # )?
Thanks.
Sure! Here is the battery I used, but check your specs to make sure its identical.
Duralast Platinum Battery H7-AGM Group Size 94R 850 CCA
@@CoderMan how long is it last??? 3 yrs ??
Did you program the car/battery? I have seen a few videos in which the new battery has to be programmed for proper charging by the alternator. Thanks.
I did not have to program the battery and have had zero issues. When the battery is the same rating as OEM the car seems to be fine with the swap. If you do need to code it, get the Carly app, the dealership charges insane rates for coding.
@@CoderMan thanks, that is the the one thing I am on the fence about doing it my self. Seems one little mistake on a BMW will cost you...
Yah, the good news is worst case the battery would drain faster. It should never harm the cAr, unless you blew something up installing it.
Don’t trust him. You need to code it, even if it’s an exact replacement. The car monitors the battery’s health and as it deteriorated it gives the battery more current from the alternator to make up for its age. The coding lets the car know it’s a new battery and to not have the alternator charge it as aggressively. Like I said, this is about a batteries age, not about swapping a battery with one with different performance specs. The extra power to the battery could cause it to fail prematurely, and who knows if it can do anything dangerous or maybe later fry a module. There are affordable scan tools that do this and this is becoming more common on batteries, not just BMW’s. Be smart and do it right. Don’t listen to this guy just because he could take some bolts off a battery and put them back on. He says he’s afraid of what a battery tender while swapping the battery will do to his car yet he is willing to do this. Makes no sense. I also wouldn’t use a tender because I agree it’s not worth the risk, but then why not code the battery properly!?
Did you reset the computer to record the battery voltage?
I didn’t. I’ve since been told by some it’s required. The car has shown zero issues, so i guess it’s up to the owner to decide if the cost is worth it.
CoderMan it’s required because as the battery ages the car slowly ramps up the alternator voltage to make up for the age of the battery, not resetting can cause it to overcharge and kill the battery sooner
Very helpful steps to follow; however, you have to deal with a very heavy battery. Lifting the battery in and out was the hardest. Do not try if you can not lift heavy item in a very tight space.
Thanks.
Great point! That battery is very heavy!
Did you have to code the battery ?
I did not have to code the battery.
Did you code the battery ?
No, but I would if you're unsure.
Do you need to register a new battery for a 2011 bmw 328i
Some have needed to. Exact replacement is not required to be coded but for the cost I would for absolute peace of mind.
@@CoderMan thanks
How do u open the trunk from the inside. Is there a trunk release button near the hood release?
Correct. When you enter the drop down seats close to the front (closest to bumper of car) you’ll see a yellow handle you can pull down. Be careful not to pull too hard, this safety device is meant to be used by a child, in case they get locked in a trunk.
CoderMan no I mean is there a button that u can press from the drivers seat to open the trunk without key fob
Iknoor Bal Oh, if the battery is working I believe the glove box has a button.
Or is the yellow handle next to the hood release?
CoderMan o got it I was tryna find it thank you so much. BMWs lol God bless
Do you have to register your battery!?
Some have required it, I did not.
Hey man, I’m a college comp sci student starting a full stack developer internship soon. I’ve done an internship before this and created an iPhone app but I’m still nervous. Any advice? Or any advice on how to make coding a side hussle as well? I’m looking to get an e92 m3 soon within the next year as a goal for me
Awesome! I do have some videos on getting started in programming, but the main point i'll touch on is focus on programming overall, not one language. What I mean by this is come up with a product or tool, use languages/frameworks you want to learn and build that thing. Learn by doing is the best way to learn programming or pretty much any skill.
In regards to coding as a side hustle, the biggest thing is to network and connect with agencies. Offer your services, only commit to things you know or can learn/execute without delay. My first Ruby on Rails project I accepted was when I didn't even know how to install Ruby.
Mainly, have fun with it. Keep learning, keep building fun projects, create a portfolio site and keep it updated. Oh and for programmers, definitely set up a GitHub account to share coding samples.
If you want me to look at any of your code or want to bounce ideas, shoot me a message. matt@pixelbit.com
What's funny about your comment and this video is... I am having trouble starting my BMW so I wanted a battery tutorial on how to take it out...But I am also in a processing of building an iOS app (swift) that I'd like to market...just started my self taught journey last year. Good Luck on your journey and you'll be driving that BMW soon. Also CoderMan thanks for the video!
That’s awesome! Glad the video helped you and doubly for a programmer! Small world.
What about registering the battery?
Allegedly not required but I would if I did it again. I had no issues. Just for piece of mind.
Is it absolutely compulsary to register the battery? Can register or code the battery on any obd2 computer?
You can use the Carly app to code it, if required. If the specs are 100% the sale you may find the car won’t require a coding.
I have uses Varta F18 battery. It is not AGM battery but what Vartas battery selector recommended.
Everything worked but the car is in limp mode throwing actutator fault code.
This failt code appeared right after my last batterys failured before i took the battery out with battery orange light.
The acutator failt code ad limp mode dissapear aftwr 10mins with new battery but came back.
The new battery is 85a the old onr was agn with 92. With varta site it says without start stop engine no agm needed, my is the first gen had no start and stop so it worked..
Just curious could battery cause limp mode with acutator code fault?
If i dont registet what will be damage?
Thanks
@@timcheou5649 It won't damage the battery, just shorten its life. You mentioned throttle actuator code. Have you ruled out needed to replace the TA? As they do fail on this car. I have not heard of limp mode with battery drain/failure. Unless the ECM isn't being powered properly. I would first check the ratings on the battery and determine if the TA is the culprit. I have a video on the channel for replacing them.
@@CoderMan Thanks for getting back to me, i have replaced it with 85AH 800CCA Varta battery F18, followed your video, I got the spec from Varta battery finder which state that if the car did not come with start and stop fuel saving thing this is a cheap and good battery to use, so i went for this one.
I needed to replace the battery because it was showing battery orange logo for 3 weeks, then finally it went into limp mode and emssiom excessive no dsc, so i relplace the battery it drove ok for 5 min then limp mode again, so i assume maybe the old battery have cause some surge that damaged throttle acutators pcb, or its a coincidence that acutators are on its way out happened same time with battery fault orange light.
I did test the old battery before decide replacing it, it was showing battery life 41 percent.
The fault code i am getting now before battery replace and after replaced are
CBDF
2B16
2b26
Cd93
Look like a dead acutator..
Thanks so much for getting back to me, i wont register the battery then as this battery is cheaper as long ss it can last 3 years i am happy. Its also much much lighter and smaller...
It is sad that standard work shops OBD 2 cannot register the battery but can reset fault codes...
As long as this battery wont damage cars pcb and electrical and will last 3years i wont bother to register..
I always work on this csr with my self.. dont trust my local work shop..
In asia wage are low... i can only afford this car and keep it in the healthiest stock setting possible.
No extra fund to mod. I only run this car in stock format.
Stock is sometimes the most enjoyable. Look for a BMW tech that has the proper scan tool, they should be able to get the DME codes.
I just replaced mine now it won’t start any idea on why?
Hard to say 100% but have you checked the connections? If you test the battery does it read the proper voltage?
Yes the connections are ok the battery is brand new. It just won’t turn on. I’m hoping it’s nothing major I would hate to spend money on something that maybe has nothing to do with it.
Great video but never saw mentioning about registering the battery to the car
Wasn't required for a direct swap. However I would do it just to be 200% safe.
Bmw of Hartford CT asked 300 to install and register the battery.
Ouch!
Thank you. Helped me out a lot.
That's great to hear!
No battery registration?
I would, if you prefer. Requirement is split between need and should.
min 4:00 what is the part number of that side (black panel ) please
I wish I knew. My best guess would be battery tray panel, but I'm not positive.
thank you for your reply, my panel is off and from somewhere the water is coming in through there @@CoderMan
Some times the car don't want to move even is on D level BMW e90 petrol 320
See prior comment..
I got this exact same battery how many ah is it 80 or 90
I'm not sure off-hand, I always recommend checking the battery you're replacing.
@@CoderMan im currently running a temporary battery so ill be coding it with veepeak im sure this one stronger i just really need to know the ah whats your ah on? 80 or 90 i checked evrey site and it doesn’t say the 80ah
@@CoderMan yea i just picked it up from autozone its a 80 ah Just for anyone else shopping online
What’s about your battery reset
Do you mean resetting the car?
Thank you! That sucked lol im using mhd to code the new battery as the new one has different specs
Good idea on coding it, when a different spec battery is.
You should register your battery, so your car knows that the battery is new, and the alternator can charge it properly. If the new battery has different specifics than the original one you have to codify it, using bimmercode, for example, or carly. If you don't do this, your car will run fine, but the new battery will have a poor lifetime.
Correct, expect in this case the exact rated battery was swapped in.
@@CoderMan still needs registration
@@CoderMan your battery is probably long dead after this video right? Cuz no registration
Can some one confirm if it still needs coding in if it’s got the exact same rating ?
@@Damian-ln3it still needs registration yep, it adjusts stuff depending on the age of the battery.
Don't you have to recalibrate the battery to the car with a new install??
I would these days.
FYI actually there is a dedicated ground point. If you pause at 1:27 you will see the metal nub poking out.
Wow, I had no idea until you mentioned! Good to know for my next M3. Thanks for letting me know.
@@CoderMan Yeah it's definitely hidden! Had to read the manual to find out.
Do you Register the battery
you can, doesn't seem required.
Yes you register all new batteries in these cars so that the charging system can properly charge the new battery, otherwise it will likely over charge.

Why register the battery replacement?
After installing a new battery, the service function 'Register battery replacement' must be run. The registration of the battery replacement is required to inform the power management (software in engine electronics and intelligent battery sensor) that a new battery was installed in the vehicle. If the battery replacement is not registered, the power management will not function properly and can lead to functions being limited by individual electrical consumers being switched off or having their power consumption reduced, for example.
Register battery replacement
A service function informs the power management in the DME/DDE of a battery exchange. The following operations are performed:
- The current kilometre reading is stored for the battery replacement.
- The stored measured values (battery charge statuses, current, voltage, temperature, etc.) are deleted.
- The power management is initialised.
Replacing the battery: other battery capacity or AGM battery
As the battery depends on the engine ands options fitted, the following information is coded in the CAS:
- Battery capacity (for example 90 Ah)
- Battery type: AGM battery or normal lead-acid battery.
For a battery replacement, the standard installed battery capacity may be used as standard. When installing a battery with a higher or lower capacity or when installing an AGM battery instead of a normal lead-acid battery, the CAS must therefore be reencoded using ISTA/P:
- With ISTA/P, run the retrofit ”Battery” (select battery capacity of the fitted battery).
- Register additional battery replacements with the corresponding service function.
Battery: battery capacity and battery type
The battery capacity can be read from the label with the technical data. The safety information is found on the other label. The cycle-proof AGM batteries are used for especially heavy loads on the vehicle electrical system depending on equipment and requirements.
Notice! Determination of state of charge after a battery replacement
After a battery replacement, the vehicle must be left standing for at least 3 hours with its new battery. It is not possible to establish with any reliability the state of charge of the new battery until that time. Possible Check Control messages about total discharge of the battery are then no longer displayed.
Thanks for sharing this info!
Maybe the bracket is for when the car roll over holds the battery in, german safety
That’s likely, hadn’t thought about a crash element. Lowers the risk of fire.
Exactly. Has to be locked in for the track too.
Did you register the battery?
I didn’t need to register the battery, I kept checking codes and charge level. The reason being the Duralast battery is within +/- 5 CCA from factory, so no coding was required.
@@CoderMan , Nice video! What is the exact model of the Duralast battery? If I need to registrar the battery and take it to the dealer, I would end up paying the battery install to the dealer after I do the work which would not be good.
Thanks, the exact battery I used is www.autozone.com/batteries-starting-and-charging/battery/duralast-platinum-battery/319459_300933_25697
@@CoderMan .. Exact question I had about registering the new battery to my Hard Top M3 .. If the power is equal to the original battery it should work fine..
Absolutely correct. The car essentially relearns the new battery without issue when it’s the same spec. Brand doesn’t seem to matter.
I’m trying this now gonna use the same battery you did @coderman pray for me lol 🙏🏿
Was a success thanks a lot man going for a drive hope I don’t get codes !
Awesome! Glad it helped.
Don’t trust him! You need to code the battery even if it’s an exact replacement! The car monitors the battery’s health and as it deteriorates it gives the battery more current from the alternator to make up for its age. The coding lets the car know it’s a new battery and to not have the alternator charge it as aggressively. Like I said, this is about a batteries age, not about swapping a battery with one with different performance specs. The extra power to the battery could cause it to fail prematurely, and who knows if it can do anything dangerous or maybe later fry a module. There are affordable scan tools that do this and this is becoming more common on batteries, not just BMW’s. Be smart and do it right. Don’t listen to this guy just because he could take some bolts off a battery and put them back on. He says he’s afraid of what a battery tender while swapping the battery will do to his car yet he is willing to do this. Makes no sense. I also wouldn’t use a tender because I agree it’s not worth the risk, but then why not code the battery properly!?
And if it’s not obvious, if you change a new battery to a new battery of a different type, this also requires coding. And depending how drastic a change, your scan tool might not be good enough and you may need the INPA BMW software to do it. Not something I recommend for a novice.
I appreciate your feedback, I did extensive research and have an electronics background. I also added a note in the post about deciding if you want to or not.
I wasn’t afraid of the battery tender, it’s not smart to power something you’re replacing, especially with delicate electronics. It’s true in 99% of cases it won’t doing anything, but why risk it?
@@CoderMan
Who cares about your electronics background. You were claiming since the battery has the same technical spec's as the old battery it's not an issue. You can be a whiz with electronics (not hating on you or doubting what you can do) and still be wrong here. When it comes to modern car's electrical systems, I wouldn't play around. They are so finicky. You'll even see people accidentally frying their footwell module on E90 etc. BMW's just from disconnecting their battery. It shouldn't happen, and they even had to extend the module's warranty, but my point is just these systems are super delicate, sometimes more so than you would want as an owner.
I am agreeing with you on the battery tender. My comment is related to an inconsistency in your approach. A tender is too risky to use because it can mess up your electronics in your car (I agree), but not coding the battery as intended and causing it to get greater charging current than designed is ok (I disagree).
100% on time reply
@@CoderMan my bmw 30+ years mechanic told me that when changing à battery on these it's better to have another one plugged up in front as you can fry your main board module$$$ and seems right as the last time my battery drained completely it bugged all the electronics and I was lucky in my case it just needed some reprogramming still cost me like 300$ for just that...
That bracket is to keep the fuse stable
Good to know!
