- The IBS can keep your BMW from starting. It is designed to monitor the battery and save power for starting. For some reason it can also keep the car from starting. Makes no sense to me.

You sir, are a scholar and a gentleman. You have my sincere appreciation. This fixed for my 2004 645Ci the high battery drain fault, and the transmission fault ( giving me only gears 1 to 3 ) . Before i would have to make damn sure my battery was fully charged and do a transmission reset to clear the transmission fault, sometimes it would often take multiple resets. The code was active on the car, i unplugged the IBS and the car drives as it should , Full gears, no codes. These faults have left me stranded afew times also. So thank you for this video. Five stars my friend , five stars.
Thanks so much for the comment and very glad the video helped!
Thank you so much for the tip. after getting a technician working on the car for two hours and couldn't find the pro which was The IBS . fixed it in 5 sec...keep it up.
That's awesome, so glad the vid helped! Thanks for your comment.
Brilliant video. I've gotten that High Battery Drain light and wondered about it. My battery is on its way out so I'm replacing it but I'm keeping that IBS trick stored in the vault in case I still have issues. Thanks for taking the time!
(07 530xi) Thank you so much! I was having the high battery drain, increased battery drain, dead battery, etc... unplugged the ibs sensor and everything is good to go... even my check engine light went out and my car runs better. Thank you so very much for this video, god bless!
Glad the video helped and thank you for providing what issues you were having. The IBS can cause so many problems. Just be sure a check the battery periodically to make sure there is no real drain on the battery.
Thanks bro was stuck at store 3 hours changing relays until I watch your video thanks worked perfectly
Thanks so much for the comment and glad my video helped!
FINALLY!!!**** Thats what was wrong. FIXED. The usual water in the battery compartment probably fried the IBS. Thanks again for the right answer.
Cue L
Glad I was able to help. water probably damaged mine too. if you don't mind. what symptoms that you have?
Wow great video, very detailed! Had this issue this morning, wish I had seen your video earlier. After much time and effort with a voltage meter discovered that the ibs was the problem. Disconnected it, and she fired right up. It's been raining for 2 weeks here, and of course water leaked in the trunk. Smh
Cool, glad the video helped! I'm pretty sure that's what caused my sensor to go bad also.
Wow. Absolutely amazing thank you for your post. I have a 06 BMW 325i and my car would not start. I disconnected the blue wire and boom, it started. Thanks again😁😁😁
Very cool, so glad my video helped and thanks for the comment!!
I had the exact same problem on my 2007 550i. went to mc Donalds came back out and no start. I un plugged the battery and re connected and boom she fired up! then went to sons school and no start again.did the battery un plugged and no go. had the car towed home next morning bought a new battery and no go......and same as you 24 hours later decided to un plug ibs plug.and car fires up!!! drove for 5 months like that and sold it. It's funny how people think alike lol great video.!!
Hey thanks for the comment. I think this is not an uncommon problem that is very frustrating and very expensive for a lot of people. It was very easy to troubleshoot once you know what to do. The part that gets me the most is that this system was designed to save battery power but designing the system to shut down the starting circuit makes no sense what so ever!
Hello my car is not doing that but the it losing battery power fast and it gives me the same message. It just doing that last night, so I'm going to disconnect that blue wire too.. thank you
Broooo I’m having that probably right now
@@arko2094did u fix it
Beautiful! Thank you sir. My wife's car was stuck in her friend's driveway, and thanks to your research and video we were able to get it moved right as her dad was pulling up to park
So glad the video helped!
Oh my God this guy is a genius thank you so much. I thought i had to buy a new battery or starter. Wow! You are amazing thank you so much buddy.
LOL.....genius. I'm very far from being a genius. I'm really glad the video helped and for your comment!!
God bless you my brother
Thank you Rob
It is the rights time to see this video, my 2006 550i can't start even everything is on but no crank, no start, i spent 3hours to booster but same thing, i give up and come back next day and it start, until 4 days later it happens again. I hear so many ideas until i Watch this video, i do exactly what you did it works, i hope it solved problem, thanks. Very good experience, God bless you
I have 2007 BMW 525i too, and started getting clock resetting to 00:00 problem. I did google search, someone posted that this might be related to the battery issue. Since my battery was already about 5 years old, today I just purchased a new battery from Walmart, and replaced the battery.
Immediately after replacing the battery, I set clock to the right time and turned off the car. Then, I was cleaning up garage. After about 2 hours, I restarted car, tried to park car inside the garage, I noticed that the clock was set to 00:00 again. My batter has a label 9/2018, so, it is quite fresh and should have enough juice. After watching your video, I guess this might be related to the IBS fault. Tomorrow, I will try to disconnect the IBS to see to if clock reseting issue can be fixed.
Thanks a lot for your video to share the issue and workaround.
Sure sounds like it is.
Thank you Robert for the video. Thank goodness that things posted on the web never disappear, your video has helped me a lot. Recently went through the whole process of replacing a battery, registering etc and a few weeks later still getting low voltage warning on screen. Even got water pump, thermostat (only 10k old) and blower fan error and several accessories not functioning power windows, folding mirror. Always suspected a power failure or bad reading somewhere, but never had the confidence to disconnect IBS. I did, cleared the codes then everything started working normally. BMW 335i N54 2008 - I love to hate it , and I hate that I love it.
So glad the video helped and fully understand the Love hate thing :-)
Thanks for posting the comment!
This video is a great education and explanation of BMW's (IBS) Intelligent Battery Sensor.
Thanks so much for the comment!
Wow, it actually works for my 2007 535xi. Thank you sir!
So glad the video helped and I appreciate the comment
what were your issues? Mine starts then stalls out after 5 mins of driving with no issues, no codes. hoping this could be my solution
Thanks to this video I've started my car again 😊🤗 thank you very much!
Excellent so glad the video helped!
i know Im asking the wrong place but does anyone know of a way to get back into an Instagram account..?
I was dumb lost my login password. I would love any assistance you can give me.

Thank you Robert!!!! Awesome video 🙏🏼
Thank you very much for the comment Matt, glad I was able to help.
Thanks thanks my 2005 bmw has not run in 4 weeks did what you said it runs great now bless you
Wow 4 weeks! So glad my video helped you and thanks so much for the comment.
I want to yell you thank u for saving me some time and money. I had this very same issue. I unplugged the IBS and my car started right up. Thank u, Thank u, Thank u for making this video.
wade kristi Glad my video helped and thanks for commenting!
A very useful video. Just unplug the IBS power and do not have to be dragged away. IBS is very sensitive to rough handling and condensed moisture.
Thanks so much for the comment!
Thank you sir👍This helped me out a lot!
So glad my video helped out I appreciate the comment
Your the best thank you very much it worked , perfectly!
Glad the video helped!
My brothers car started after this tutorial . Thank u , Thank u , Thank u
That's awesome! I still can't understand why they would design it that way makes no sense. Especially because it's German engineering.

Thanks very nice video I'm having issues with my (2008) bmw 750li no start battery discharged
The battery is (1) year old AGM very expensive too I paid at the dealer $557 I don't know what is the problem is it a automatic car wash that did. when i open the door and insert the key in to the ignition the flywheel start turning by itself without starting kind of a grinding noise
some they say it's power control module and some say VVT. / BST BMW electronics no good. too many sensors for nothing. Sound system that logic 7 no sound in the speakers
recharge battery . I did install a new battery from my wife (Mercedes Benz S500) 2005 but that did not work again recharge battery. My (2004) BMW 750li Is running fine i don't want touch that one. I like the way you show the BST cable again nice video thanks
IBS basically is a negative battery terminal with a computer on the end of it. A malfunction can cause several problems, including the fuel pump engaging every 15 seconds, even when the car isn't running, thus draining the battery.
Thank you. You saved my day! Was able to start it up without paying loads of money. Thanks man
Zaman Khan Glad the video helped!
I am going to try this thank you.is there any possibility that this could cause a trans malfunction light to come on occasionally that you know
Hi Robert, Just watched your video re: IBS ...
Gotta say Big thanks for that, I've had the RAC look at my e60 with the same problem as yours...He couldn't fix it ?
An auto electrician wanted £70 just to look at it ? Telling me it could cost a small fortune to fix..
Just as I was about to give up I came on here, watched your video and BOOM💥 It worked 😄 You saved me a pot of dosh and a shit storm between my ears man, Thankyou !

That's great, glad I helped you!
Yoooooooooo tank you sooooo much. Appreciate your help. God blessed you brother
Thanks so much for the comment!
I'm had the exact same warning control messages you did on my 2008 328xi. Literally the first time my clock reset when I started it after work one day almost as if the battery was disconnected and reconnected again then it gave the control message you had for battery discharge with a pic of a car on a lift. Im almost sure its my IBS sensor now I'll try this fix after work.
Thanks very much dude! Iv been pulling my hair out over this. As soon as i disconnected it started.
That's awesome brother! So glad my video helped another with the same problem.
Thanks for the comment
I have 08 528xi, and I don't see that blue wire. I have the same symptom, I took battery to check and it's good. When I pressed the start button it just clicks and that's it
Bro your a straight up angel!! I’m going through this problem right now. Bmw said 486 with terminal and adapter. I jus replaced the positive battery terminal it was $420 now the negative terminal gave out this morning. Drove to drop off my uhaul because I was moving turned off the car went to start and didn’t want crank. Accessories and all came on no sound no crank to start tho
If all your accessory lights came on probably not the IBS probably the starter I had exactly the same thing as well.
Good luck!
@@Nobobs62 the negative terminal for the Ibs is what sends current to the starter if it was my starter it would have tried to crank and turn over its did the no crank no start like in the description and like 2 months ago I jus replaced the positive battery cable so I’m sure the negative went out
@@Nobobs62 starter! 😂😂😂😂😂 you right it’s going to the shop Monday cuz I don’t have time to work on it I work 6-12s so it’s gunne be there for a day or two saves me my muscle strain tho
@@Nobobs62 it gets to be touched by the fancy tools and air sockets she’ll be in great hands
Thank you for good video, i have same problem and your video really help.
Glad my video helped!
saved me so much money . THANK YOU
thanks. this fixed my problem.
Your welcome!
Best video on the net. I love you saved me over 1k for getting a starter just to be upset
That’s awesome, thanks so much for the comment!!
Thank you a ton Robert!
Glad to see is my video helped!
I'm replacing the battery AND the IBS on a 2017 F15 X5 (the bad IBS caused the battery to be flattened out several times). Those IBS are also affecting newer BMW.
Love that car 2007 bmw 525i
This worked for me!! Thank you for posting this. I already knew my ibs was damaged after I hit a deer
Thanks so much for the comment and glad my video helped!
😮 that actually worked....had same problem with mine.....watch this video & it fired straight up 2006 530xi
i have a n54 and might have a bed plate leak ... do you know where i can find a alignment tool to put it back on
Thanks for the video. I have a problem I put a new battery in and the car was sitting for a month a the battery died.now I'm buying an oem and hope for the best
thank you very much for your video i bought a new battery and my 745li wont start and as soon i watched your video it started
Very nice!
THANKS SOOOO MUCH for this video, u save my life, I have the same issue with my bmw 328. Like 5 days before the issue start I have to set time and hours like 3 time it was weird to my and thet the day 6 the car don't stat at all, I did the same thing u done and pum it started, thank man for the vid andGOD BLESS.
Thanks for your comment. So glad my video helped you!
Thank you so much for this tip. Worked a treat,
Thanks for the comment and so glad it worked for you!
It's an ATG IBS used to monitor electrical & computer circuits.
Don't get scammed by dealerships.
I have removed the ATG and hit $32,500.00 to get the Lamborghini Huracan. Plus the battery prices.
ATG say you can clear everything by using BlueDriver and save you money for not getting OEM battery.
good to know, thanks

Another symptom of the IBS lead failure is various systems start to shut down. I've had it where the radio / idrive would not work on position 1 on the ignition. i.e the ignition is not on fully but just at the first (what we used to call) accessory setting. Put ignition on so the dash lights up (not starting the car, and the radio would b fine. The AC / heater blower would only work to it's 2nd speed and no faster. And it dips to its lowest speed if the car sees another power drain. if I hit the brakes, as soon as the brake lights illuminate, the blower dips to speed 1. And it was slightly slow to crank. Never failed to start, just slightly slower. Disconnected the IBS lead and hey presto. Radio and blower all back to normal and spins over perfectly when starting. Why oh why do they build pointless systems into cars that serve little purpose than to break down over time and give issues???? Great video by the way.
Thanks for the comment Trev!
I get the purpose of the IBS, save battery, but I'm totally baffled as to why these great German engineers would let the IBS effect the car start system!
Thankfully the did design it to were the system can be disabled.
I wish I knew this a little earlier 👍👌
Thanks for the comment!
Robert...You are my hero !!!!!!!!!!!!!!!!!!!!! Thank you...and you did save me money!
So glad the video helped! Thanks for the comment.
@@Nobobs62 Robert - Are you an engineer?
Robert - I know this vid is @ 4 years old....may I ask, how long and how well - did your BMW operate with the disconnect?
@@gregpalumbo2503 I did replace the battery about two or more years later. I did because one cell was going bad and it was under warranty. So to be honest I really don't think not having the IBS sensor in there did it but it is possible.
I sold the BMW about a year ago.
THANK YOU SO MUCH FOR THIS VIDEO, Sir!! Been having this issue for months and I knew it wasn't my battery since I just bought a battery. 🤦♀️
Hey thanks so much for the comment and so happy the video helped you out!
Same ill try this tomorrow
I was told by the dealership that replacing the battery but having a battery drain (caused by faulty IBS) could flatten a battery enough times to have a battery only a few days or weeks old to be replaced. Basically a bad IBS is battery killer.
@@Scotford_Maconochie The battery charging system with an IBS is supposed to make batteries last longer and they probably do but when the IBS is disconnected I believe the charging system reverts to the old way of the voltage regulator in the alternator doing all the work. That basic system mite shorten the life of a battery compared to the IBS system but its my belief that it’s not a drastic difference. After I disconnected the IBS sensor on my car that battery lasted for over a year and I can’t remember how old it was prior to that.
In the end do what you think is best. My comments are just opinions
@@Nobobs62 the mechanic found that "transport mode" having switched itself on for unknown reasons and was causing the battery to go flat repeatedly. At first I thought it was the weather to blame since it's been hovering around -15°F here for a few weeks. Still I replaced the OE battery that was less than 4 years old for another OE battery of the same spec, the IBS and had a battery maintainer installed as preventive measure. Once "transport mode" was disabled using an OE scan tool, the battery keep its charge since. Problem solved!
Hey man, thanks for the video! I had the same problem (with my BMW 2007 525i),but after plugging off the IBS, it's running pretty cool! I was wondering, will it be a problem in the future if I won't replace it (just drive like this for couple months)?
The IBS allows the charging system to make the battery last longer by efficient charging with this disconnected it goes back to an old school regulator system which is supposed to shorten the life of the battery I didn't find that on mine but it could.
That's the only thing I know that changes when that IBS is disconnected
Hey Robert this video was posted 3 years ago has your battery went bad Since? Just wondering? Great video btw
Hey sorry for late reply. I did replace it about a year ago I think. The voltage was fine but seemed a little weak. Testing said one cell was going bad. It was still under warranty so they exchanged it.
Did the lack of IBS cause this? Could be. Could also have been just a flaw in the battery. My thought on it is just a flaw in the battery. I sold the car a few months ago. So I won't have any more data.
Thanks a million
Hello I know this is an old thread, but what is the ibs sensor, is it the blue connector that is disconnected??
exactly the same thing happened to me,but it seemed to have drained my battery overnight,i have disconnected the ibs cable and it now starts,thanks for your great video,hopefully its as simple as this.many thanks
Glad the video helped!
@@Nobobs62 hi,again just an update to say the fix still is working,i have had no starting or battery or power issues since using this fix ,as far as i can tell its a perfect fix.thanks again.
@@jasonmartin3685 that's great news!
I have a 535d m sport with alternater regulater problems unplugged these 2 wires and presto no problems no warning s car flying but I will put a new alternater on it to be sure
Thanks so much man ... ! You are a lifesaver ! I only disconnected the blue shit and the car started !
That's awesome! I can never get over the fact that they designed it that way makes no sense especially because it's German engineering.
Yeah ! Many thanks m8. to bad that i bought a new battery but the old one was 12 years old!
I have a 2007 750i it was doing the same thing so I watched your video and went outside and just moved the wires and it cranked up
Very nice!!
good info thanks
Your welcome and thanks for the comment
hope this fixes my problem
Hey Robert I am sorry to disturb you but before my battery drained a engine temperature too high error occurred , does that count ?
My thought would be no. The engine temperature wouldn't have anything to do with the IBS sensor that I know.
Thanks
did u try reconnecting the ibs after battery change?
Yes I did, it still would not start. I have no doubt my IBS is defective. No problems at all since I disconnected it.
I have a bmw e90 3 series 325i and have replaced the alternator and the starter and battery went this morning to crank car and nothing put my obd scanner and got the code 2E8B for the battery sensor I’m going to unplug it and hope it works this E90 coupe has been a nightmare just tired of the dam thing hope it works great video thanks
I hope so too
I got up this morning unhooked the sensor and gave it Lil jump didn’t do nothing at first but tighten up the positive some more and negative and car turned on seen that my cable on other car was disconnected wow crazy lol 😂 but car is on hope it turns back on letting her warm up keep you posted
Very helpful thanks for the good info...
5:24 video of IBS in trunk
very helpful. just try to keep the camera from moving so much, it gives me a headache. Try a steady tripod, and use tools or fingers to point at the area you're referencing. other than that, really good content.
Did you ever think about replacing the ibs cable? Have you had any problems having it disconnected and or do you know of any problems that can happen if you leave it like that? Great video by the way and thanks again!!
No I never thought a replacing the cable or the sensor. I get the concept that the IBS CAN prolong the life of the battery but the cost to repair it and the fact that it can keep your car from starting makes it not worth it to me.
No problems at all leaving it connected.
Robert Edwards so my car finally gave out on me and won't start. I have a 2007 328i. I disconnected the blue plug but what else do I have to disconnect?
Johnny Bautista that's it. if that didn't fix it, the ibs is not the problem
Johnny Bautista does the car power up with the second push of the right switch?
Johnny Bautista if it does probably the starter or battery
Wish I knew this on my first 2006 530xi.. brought it to the stealership and they charged me 5k for a new mechtronic unit. I went to the beach went in car after no start.. disconnected barrery and it started but drove around d for a sec to test it turned it off and it went out again. This time I decided to get it towed to BMW. Wish I just unplugged the fing ibs. Smh
hey where did you get that bmw information that you have on the screen
The web site is at the 3:21. Bimmerscan.com
Very useful video !! I had problem with battery discharging overnight and in the morning the battery was completely flat.
I disconnected the IBS and the battery keeps full capacity now.
But may I have a question...if the IBS is disconnected is there any possibility that some other part would get broken ? Or can I keep it disconnected with no doubts ?
Thanks you
Mine has been disconnected since December of last year, no issues. One of the functions of the IBS is an intelligent charging system had should extend the life of the battery according to BMW maintenance. Keep word, should.
When the IBS is disconnected you have just the alternator and regulator. That system is simple and tends to work very well. I won't be replacing or using the IBS from now on and I don't foresee any problem.
This is what I'm comfortable with. Do what you think is best.
Thanks for the comment!

This is an absolutely brilliant video. My car starts every time just be getting the warning battery dechanging and a picture of a car on a lift Icon. Well I have had my battery checked and everything is fine. I was thinking it may be the alternator as it had a slightly low charge. Until I discovered IBS and what it does from your video. I'm going to try to disconnect this and I hopefully all will be well. Just a bit worried about the iDrive. would any new icons warning information come up. I have a bmw 2009 e60 520.
Hey Peter,
Glad the video helped! The icons associated with the IBS will not be there because it's not connected. The most important thing for you to do is to check your battery often, daily would be best, until you know for sure the problem is the IBS and NOT the battery.
Thanks a lot was great
Imagine how much it would have cost you at BMW dealership .
another way they design car to make money after sale ,they could made it they way car would start but check engine on but this way no one would take it to dealership
Glad the video helped thanks so much for the comment!
Robert Edward:
How long have you been driving the car with the IBS not connected?
Since I first posted this video little over two years ago I believe
@@Nobobs62 sounds good I was debating if I should just continue to have it disconnected or should I even bother replacing it with a new IBS sensor.

great video robert, learned alot about ibs system. my concern is that you may still have discharge but have masked the problem by disconnecting the component that warns of the problem. you thoughts appreciated
You are correct if there is a real drain on the battery DO NOT disconnect. You only disconnect the IBS if the drain is not real.
Robert
There are many ways to troubleshoot but the easiest would be to simply check the battery voltage before and then after the car sits for awhile, say overnight.
I'm going to check out my car first thing in the morning I am going through the same thing I will let you know by morning I really need it to start my car is a 2006 530i fingers crossed
fuck the intelligent battery sensor... lol, i thought my car will not start for good... lol.... but it did... THANK YOU....
Yep, pretty much my thought too!

Thank you for the follow up.
I got an 08 328i, I have the issue where every thing turns on, except the engine doesn't start.I removed the ibs and still didn't start, even though everything else was fine as if the engine was on.Perhaps it's the starter since battery is also good???
I also noticed that there was another wire that was not plugged in anywhere that resembled the blue ibs cable but in black. I'm assuming it's ground?

Drove back home stopped at gas station and would not start after filling up with gas. had to have it towed again??? Please help!
Sorry for delay, had been a really busy week.
I haven't worked on a 3 series but I'll try to help. Do the Accessories power up if you press the start stop button? When you 1st put the fob in the car or you are sitting in the car only thing that should be coming up as the little key symbol 2nd press should make several lights on the dash come on, does that happen or not?
Nice 10x
Most annoying is that you have such and "intelligent" sensor, but no error messages appear to hint you what is wrong with the battery.
Agreed!
How did you disconnect the ibs plug? I located the sensor but I can't separate the plug. What's the trick?
Btw my 545i exhibits similar symptoms in that the engine occasionally does not crank. All electronics go on but the engine won't turn over.
I thought it just pulled out. I'm going to make a small video that shows how to disconnect the positive wire and the blue wire. I'll let you know when I do
If the car powers up on the second push of the start button it's not the IBS. Probably starter. I made a video for that. Not a great video but it mite help.
My car Z4 E89, one day fine, next no start. Code says it's hall sensor key slot fault, but tried a 2nd hand replacement and both keys, still the same.
Code reader gave out historical battery charge, day before fail, 99%, now 39%. Something drained battery.
So now fully charged. Still no start.
I will disconnect the ibs tomorrow just see what happens.
I hit a dear and my car started showing codes for this and now my car will not start and wouldn’t come out of gear this little thing cause so many problems
I have a 2007 750li and I can't seem to locate the plugs that you are referring to ,do u know where they are on this model?
GEE POOK Sorry but if it's not in the same spot as mine the only thing I can tell you is look to see if you have an IBS and if you do just follow the cabling back it should be a two wire connector
Robert Edwards I did what you said and I found a connection coming off of my positive cable nothing off the negative ,I disconnected it and the car fired rt up . However don't know if this is the problem cause it tends to start sometimes and some times not but I will monitor it for now since I disconnected this cable and see if I still get any no starts .thank you for responding I appreciate it ...
GEE POOK. Now the IBS is connected to both positive and negative post the thing to look for is the battery terminals themselves the negative should be quite a bit bigger. You may have just found the connector that sends the positive signal to the processor on the negative post and that may just cause they censor to be inoperative. Mainly you don't want this to be a real drain on the battery
My windshield wipers won't work when raining
I have a bmw 528i 2008 , changed the battery because it wasn’t good anymore and now my car doesn’t want to start, the lights turn on an off and I have codes popping up like transmission , abs etc . it turned on properly yesterday but didn’t want to go into drive or reverse , now it doesn’t want to turn on , not sure what’s wrong
Sounds like the new battery is bad from stock. I'd have it checked out
I have a code cc-id-97 and my car won't crank, also disconnect IBS and still no start. Help
Do you have a DVM (same as DMM)?
You want to check ground (known metal on engine) to hot (+ red).
Then check starter the same way.
Hi let's see if this reaches out to someone I just replace the battery in my 2007 BMW 550i everything lights up it cranks but doesn't start. Before I replace the battery I was getting random none starts just clicks when it would crank it starts. Now again after replacing the battery it cranks but doesn't start!! Any ideas
If it's turning over, it has to be either ignition or fuel issue. Nothing to do with the IBS. The IBS fault wouldn't let it turn over
It didn’t work for my 2007 550i 😩 could it be the ground? Or the starter maybe?? gonna try the relays next I guess 🤷🏽♀️ thanks for the video
Does the dash light up when you push the start button without your foot on the brake pedal?
50 seconds into the video
Yes it does
@@patriciacordova9375 My best guess is that it is the starter. Not a fun job
