I just changed the battery in my E39 a month ago, back in 2000-2003 they did not put all those annoying, nonsense sensors in their cars. Thanks for sharing, good to know there are shortcuts for these problems. Keep it up!
BMW dealer last summer charged me $1100. To change a battery. One year from that new battery and now dropping in another new one next week. This was very helpful. I’ll let you know how it goes with the sensor wire disconnect on my 06/325i
Old school mechanic here, cool video. Those are one of the many tricks when replacing your battery on a BMW without registering the battery. Another trick, is when you replace your AMG battery with another AMG battery. All you gotta do is install the Negative terminal first, wait 10sec. Then install the positive terminal, wait 10sec. Then start car, the car will start. Then reset time on your vehicle and everything go back to normal. Like I said that's one of the tricks to do when changing out your battery, with out registering your battery. But overall very helpful video.
@@U4Eye Old school mechanic, I work on alot of cars, thanks for your point of view, but from my experience in automotive. It works out fine. But hay that's just your opinion.
@@mikey358976 That's probably a bit scary, but hey. If you've been doing that and it's working. All good, I'm not expert so will probably avoid doing the Neg. first. Just to be on a safe side.
Textbook mechanics who don't know the how come and why or the ones that are afraid to do negative terminal first. If you understand the theory you can do the negative terminal first but you have to be very careful not to orc or spark or ground by accident the positive cable.
I’m gonna replace an AMG of same model with another AMG. If I go with the negative first would it work fine ? Coz according to bmw the registration is not for the battery for alternator to control charging power to the battery
this will get you out of a pickle but registering the battery will let the computer know how to properly charge the new battery. not doing so will just make your battery life shorter and possibly have other battery-related issues down the road
Thanks for the vid. I put a new digital cluster in my E92, and the batter registration was deleted or something, because it started acting like it did before I registered the battery several months ago. Inpa wouldn't work with this new digital cluster, so I had to disconnect that sensor, and it seems to be working better. So thanks for the vid. Cheers!
Why does BMW have to make everything so difficult, to make more money? They probably sit around a table and think about all the tricks they can put in there car to gave the consumer pay the dealership. I bought my one and only one BMW from my son he had put a lot of money in it and it was a tricked out ride so I bought it. Its a nice car but I have about $9K of parts and labor in the car since buying it. My Chevy Tahoe I bought in 2010 I have $200 for a battery invested in it. You make the call....
Thank you @Welding and stuff!! Great fix on my 2006 325i. Im in california and the dealer wanted 190 just to install the new battery I already purchased for 210.00 This has been so frustrating but I love the car!! Back in the drivers seat again and MOBILE!!! tytytyty huge hugs and a big shout out to you for sharing your video!
Thanks sir for the video. You right German cars make so stupid and difficult on cars I have the same situation. After I replace my battery electrical problems pop.
I felt it in my chest when you said that joker was heavy that imma need a man😂😂😂😂 And mine is 299$. I have a 2007 750i and it wouldn’t start after I put the battery back so I’ll try this 😢
Thank you. You are the best. I've been fighting this thing for 2 days! The only one to give me useful information and not try to sell me something. You are a godsend!
My wife wanted this BMW we have. These are cars idiotic & poorly designed. I’ve had 2 Lexus cars & I change the battery in minutes when they die. Can’t wait to get rid of this thing.
im about to buy a replacement battery 07 530i. The wire is ibs, i think all it does is moniter the battery and lets you know if draining due to anything or when it’s low. so you’re battery may die without the car letting you know. too many repairs up til now, so i thank you, helps me and think im doing the same
This is a scam used in the UK as dealerships wanted guaranteed income. Most avoid main dealers and go to independent garages. The more dealerships complain, the more things need resetting each year that didn't previously. There is nothing in the battery that talks to the ECU. So charging is never cut or reduced in any way.
Oh my, I've been looking at videos all day. Your's is the first one that said anything about the little blue sensor. I'm fixing to try it right now and see if this will let me start my car
Just leave it unplugged, bmw are just trying to make more money, I have a 6 series with IBS sensor and I leave mine unplugged, the alternator output is controlled by an integrated voltage regulator and this itself is to prevent overcharging, car companies will try everything possible to make more money
Hey there, I was wondering if yours had a red , seems like some kind of lock on it? I'm trying to disconnect mines , I'm losing days of work over this 😭
Awesome video brother.. But look, I read where the alternator works on these (well maybe 7 series only? 02+)like an A/C clutch to keep from overcharging the system, so it cycles. Is yours charging OK and does it cycle like a 7 series? Thanks for the video.
All those programmed controls are in the BMS. There is no clutch on the alternator. The alternator will not overcharge the battery because there is a charge regulator built into all car alternators. The BMS operates separately from this but inline as it is installed on top of the positive post of the battery on a BMW. It can work fine sometimes and be a pain in the butt the rest of the time. Many regard it as another way to sell high price batteries and additional scam reprogramming.
Don't do this, the battery needs to be registered. This will over charge your battery and you will have to replace it again in a few years. The car will over charge the battery. The car needs to know how old the battery is.
Yep you’re 💯% right!!! I’ve done this too almost 3years ago now and didn’t need to register. Don’t be scared people. Get the same battery voltage and do the same thing.
That’s a great hack! Thank you for that info. Now let me give you some. There is a code reader out there called Launch Elite 2. This thing is very affordable and will allow you to code your battery your injectors and pretty much anything else to do with your BMW. You can put new plugs in and check to make sure they arefiring in spec. Just hook it up to Wi-Fi. Let it download the downloads that are available and you are set to go. There are also additional downloads that you can pay for such as for Audi. It’s $58 if you need it. You get free downloads when you hook to Wi-Fi if downloads are available. After being told we could not access BMW computers without going to the dealership this code reader is a game changer. Also, if you find anything that this code reader does not address, you can send that information to the company and they will include it in a download.
Sure it works but eventually your battery gonna die or u will short circuit electronics I would say do it if you have to but eventually do get it registered so the ecu can tell the alternator how much power it should charge the battery otherwise you will over charge your battery and have to replace you battery after a year or so since the older a. Battery the ecu tell the alternator to put more power in to the battery but again as I said if you must you must
(After installing a new battery on a 2008 E90 335XI sedan model): I disconnected the blue connector from the negative battery terminal.

Thank you! It's frustrating trying to do something as simple as change a battery and not have my car start.

BMW are delicate cars. If you cannot follow the procedure or get the coding tools - you need to reconsider your car choices and maybe stick with Toyota.
I believe that's the IBS sensor, and it tells the alternator how much to charge the battery, without it being pugged in you run the risk of damaging the battery and shorting it's life.
Pretty sure you need that cable plugged in to make sure the battery lasts. I hope no one unplugs it and then leaves it for good. You gotta get the battery coded in ASAP.

Roughly how much does a garage charge to code and register the new battery after DIY fitting?
I paid $265 at Auto Zone, so that would be around $265,000 at the dealership "lol"
its $130 at sams club -$20 core fee
Thank you bro, I was stranded for a good 8 hours with the car not wanting to start. Thanks once again!
