[@espperre]

Great video. Question on the last portion regarding the BST. Are you saying take a super long jumper cable and connect the positive terminal in the engine bay to the positive terminal of the (same) car’s own battery in the trunk? Any risk/dangers with this? Because I may try this to start my car. A regular jump with another car or battery pack isn’t working. So I suspect it’s either the BST or IBS. But I want to trt this before I mess with the other two. Cheers.

[@RANDOMFIX]

Espperre, YES, basically, since the battery is all the way in the trunk, you would be essence just completing that circuit if your BST (battery safety Terminals are blown ) you can also use a test light or voltmeter right at the jumper ports in the engine bay to confirm that you indeed have power at the jumper ports. Does that make sense? There is a lot more to this but essentially if your motor is not cranking this would be a great place to start. _RandomFix

[@espperre]

Kylo Ren I never tried it because I ended up replacing the IVM module instead. Haven’t had starting issues since! It’s a common cause apparently as water can get into the casing where the module sits and cause corrosion. It took about 2 hours and $125 part from the dealer. Fixed everything and the car runs better too. My first recommendation is to replace the IVM module if you’re having starting issues.

[@robertdostie486]

Good morning. Thank you for your video, quite informative, and so much better than having to go to the stealership for a simple fix. One thing that it not mentioned here, or anywhere else that I could find, is that when we go into the front fuse box in an X5-E70, and we unscrew the little green thingy to pull it down, we sometimes have to really force it down to get to those tiny upper fuses, which results in stretching the main (red) wire that comes from the battery. I had this happen yesterday and this morning, after thinking about it a bit, went and jiggled that wire, "pushed" it upwards and back into place and the beast's lights came on, all the whirring sounds came back, and it started up like a charm.Maybe a temporary fix, but it works, costs nothing, and easy to redo if needed until a more permanent fix is done.

[@eliteshooters2180]

great videos! I tested the starter and I had power at the starter. Do I replace the starter or is there something else in line to look at? Car doesn’t not crank but I hear fuel pump engage.

[@RANDOMFIX]

If you are getting ateadt power at the starter and also the signal for the starter solenoid to engage then it is the starter. I have tapped on make faulty starters and got them to start. One there possible conclusion is that you motor is seized. So try turn the motor from the crank shaft. I have had cars with ac compressor sieze and caused the vehicle not start so removing drive belt helps. Good luck and let me know what you find.

[@flowerortiz907]

Thank you for posting this.. I will check my IBS tomorrow.. now if it’s the IBS is just a fuse?

[@RANDOMFIX]

Flower ortiz , the ibs is actually a sensor , if the ibs is bad you can try disconnecting it and then try to start the car. If that doesn't work, you want to then verify if the starter is getting a signal from the ignition to engage and start the vehicle. There is a link in description with that video. Best of luck.

Great vid it sort of helped me but not quite I get both the "high battery drain" and "increased battery discharge" but my car (2010 BMW 535i xdrive) cranks and starts like it would with a new battery and my battery tested good. Any advice?

[@RANDOMFIX]

Aaron, your battery might be good and may not display any symptoms of failure if it's your daily driver. I would highly recommend checking (1) IBS connector plug, make sure the connector is snug and there are no breaks or visible damage to wiring or connector. (2)if you can't find the problem disconnect the negative battery post wait about an hour reconnect it, sometimes the modules are these BMW just need to reset and this will do that. You may lose all you radio preset + clock setting + engine management data (3)lastly, order the original BRAND NEW IBS from BMW and install it. Let me know how it goes and best of luck. _RandomFix

You have a leak somewhere and the short is draining your battery. Possibly some modules are soak.

If it was clicking before bypassing to the jumper port, then it starts with the bypass then need to check the grounds and connections including all relay ports. Keep me posted

Question: I came out the store and noticed my front and back windows were halfway down on my 2007 BMW 530i. Found it on odd, got in car, let them up and car started and drove to next store. Came out store unlocked car got in put key in switch and car will not start or turnover. Any idea of what this could be? Everything powers on the inside but nothing when it's time to start. I disconnected the IBS from the battery and tried to jumpstart the car but still no success. I've seen a few videos talking about different relay fuses that could potentially be the issue but no idea of what it could possibly be. I've had no issues with the car starting as the car would start with no issue. No codes popped up. The last two things that popped up on display after trying to start the car were "Battery Charge Level Low" and then steering wheel locked up and car wont power to even put in neutral or radio come on. Any insight would be greatly appreciated. Thank you!

this is the exact issue i’m having. but mine also says transmission malfunction and all the lights on the dash popped up , as well as “electric water pump cut off” and a bunch of other codes. car would start before and i would drive it around to see if i could get a log but it wouldn’t even go past 30 and when the speedo went past 20 it dropped down to zero. Wouldn’t shift either and the only thing i’ve replaced is voltage regulator. when car was running did a voltage test and read at 14-15v while idling. now car won’t turn over and only goes into accessory mode.

[@DuaneDonaldson]

If you get a signal at the lower stater solenoid terminal and the starter does not crank, before you buy a new starter, remove the terminal and clean it or give the starter a whack to see if it will crank, sometimes the terminal is corroded and only needed to be cleaned if a whack gets the starter going then go ahead and replace it or see if you can rebuild it yourself with new brushes and other parts that might come in a kit. Some cars will come with codes on your scan tool for the CAS module which monitors the starter for not cranking.

Ahmad, It sounds like you IBS has an issue or was working correctly and the previous owner knew and purposely unplugged to get rid of the INCREASED BATTERY DISCHARGE MESSAGE that would normally be displayed on the dash/I-Drive System. Given you car doesn't have an actual starting problem, sounds like you have a battery drain somewhere that will keep it from starting. I would lock the car than wait 15-20 seconds to see if you can hear any buzzing (maybe the fuel pump/ throttle body / etc ) aren't powering down.Then try these steps below. 1. Load test the battery ( make sure you battery is NOT playing tricks on you IBS ( BAD CELL, SURFACE CHARGE / ETC. ) Load Testers are under $20 and can be used to check the charging system as well ▶️Video on how to use a load tester kzbin.info/www/bejne/kKHIkKKFir-mi9U. Battery Voltage should be 12.6v or higher, if your voltage is lower than this, trickle charge your battery with the negative disconnected (Straight to the battery because the trickle charge will never stop charging because of the possible drain or even remove the battery to charge, make sure the area is well ventilated). Links are below this on to safely trickle charge your BMW ▶️How to Trick Charge a BMW kzbin.info/www/bejne/bXfWmphroLh4kKs. 2. Check the charging system. 3. Complete a battery drain test using a multimeter. Your BMW should go in sleep mode after 15-20 seconds and should only be drawing 0.02 amps ( THE IS PURPOSE OF THE IBS SENSOR, TO Check DRAW on battery ). Fake Lock the trunk to check fuses in the trunk / Than fake lock the passenger door to check fuses in the glove compartment while removing one fuse at a time to see if draw decreases. Once you isolate a fuse (circuit) see what's on that circuit and visit www.bbbind.com/tech_database.html for a free wiring diagram of your BMW. Let me know if you want to make a video on how to do this step. Best of luck my friend. -RANDOMFIX

You need to verify you are getting fuel ( east to test) spray starter fluid into intake bypass the mass air flow sensor so you don’t damage it) and after confirming have.

I just installed a new alternator a month ago and the battery died on me why I was driving. Would this be the Ibs?

[@RANDOMFIX]

Once the vehicle starts and dies it most unlikely it is the ibs. Did the lights dim before the vehicle died? Did the vehicle start after it died? Did the battery have any power to restart? The state of the battery after the vehicle died is key find your answer.

[@fredito60]

@@RANDOMFIX the battery was dead at first, then started about 15 minutes later then died again. Got a new battery and it started right away but I’ve been afraid to drive it and it die on me

[@RANDOMFIX]

@fredito60 check your charging system. The alternator is supposed to keep the battery topped off and fully charged. When the vehicle died it had used all of the available energy within the battery to keep going. After it turned off the battery was able to rest and start your vehicle after 15 minutes. But each time you do this the battery will be weaker. I show the tool that use to test the battery and alternator in this video kzbin.info/www/bejne/mYeZf5ithbyiaKcsi=MBC7an9mv8zyPkdq Keep me posted

Weird I know... I put a new battery in the car thinking that was the problem but I cant read codes because I cant turn the car on...? what do you suggest....? I took it to a so called bmw Mechanic and he said the key fob needs to be replaced to the tune of $2,600 I found one online for $300 bucks... haven't ordered it yet because I don't think that is what the problem is.... this car has never had any problems until the flat tire episode... any help you can give me would be wonderful thanks for your time...I really don't see have having a flat could cause the key fob to go out...oh and the mechanic wanted to replace all the computors and modules to the tune of $6000 and reprogram the entire car... I think his rent was due and he needed some vacation money...

Hello .. Good evening! I have a BMW x3 2012, it is presenting a low battery warning. Do you think the problem is in IBS? Do you think I have to change the battery? Or do I have to upgrade the system?

[@RANDOMFIX]

Patrick, great question. Your symptoms can be caused by a number of different components. First I would check the battery to see how old it is? (normally there a is a sticker with a date on the battery, your 2012 bmw x3 battery could be the original and maybe just old) After checking the age of the battery I would do a load test ( video kzbin.info/www/bejne/kKHIkKKFir-mi9U). The load tester in the video is under $25 and can help you identify if it's a battery issue or charging issue. The low battery warning your are experiencing is not normally associated with the IBS. If all checks out before you change the battery try a low amp trickle charger like one of these, under $35 ▶️Link to HIGHLY RECOMMEND charger amzn.to/2gmm473 Let me know how it goes and if does need up being an aged battery make sure you get the same exact battery type and amp hour rating or you will have to register the new battery which can run a few dollars. Check out my BMW E60 battery install video for complete details about changing out BMW batteries. ▶️kzbin.info/www/bejne/j4W0p353oZKaZqc p.s. A poor performing battery can cause numerous other electrical issues so try not to delay repair or replacement or maybe just the recommended trickle charger above if your lucky!!! _RandomFix

When changing the IBS sensor do you. Red to reprogram it?

I didn’t plug it back in, on that vehicle I don’t believe it required programming how ever if you have a newer bmw it may require it. I think it acts like a battery shunt and detects with the battery is discharging when it’s not supposed be. For example if you vehicle is off and there is a large draw on the battery this will detect that and let you know there is an increase draw.

[@RANDOMFIX]

You need to check if there is power going to main jumpers under the hood. There are fusible links that can break. These fusible links are normally near the terminal post of the battery. Make sure the battery is connected and the work backward to see where the power is being stopped. I show it here kzbin.info/www/bejne/fXS3Zo2insllmqssi=PLBTOo1eQq3vPf4K

Having the ibs disconnect may shorten the battery life when it is working properly as designed. But like I showed in the video the ibs system has many flaws so you have to repair other components to get the system to work properly if that is your fear. Many people drive around with the ibs disconnected with no issues.

[@RANDOMFIX]

@@vzfox1 I think you have some sort of parasitic draw since your BMW battery was replaced one year ago with the correct BMW battery at BMW. I would only replace the ibs sensor with an OEM IBS sensor. If you looking to find a possible fix I would try to get all my modules offline and resetting them by disconnecting the battery. This is often overlooked but free to try, You have to go in this order, first lock the vehicle with trunk open, wait 1 hour to confirm the vehicle is sleep mode, disconnect the negative cable for 2 hours at least, reconnect the negative cable, and yes you will get all sorts of warning lights on your dash afterwards and you will have to reset your clock, etc. This will also reset all your drive cycle information so make sure you don't have an emission test around the corner. Yes, the cold can trigger what you are experiencing but I would really perform a parasitic draw test after your replace IBS.

Hi, i have a 2009 525i e60, My car constantly going flat, what i have noticed is that once i park the car and turn the ignition of the car will go flat within 2 minutes and will not start unless its jumpstarted. The only way it doesnt go flat after being parked and the ignition turned off, is if i dont open the car unless i start the engine. The battery and alternator have been tested and seem to be fine. Any suggestions? Could it be the IBS? or even the tyre pressure monitor? Please help im trying to fix without having to go to dealership. Thank you

[@RANDOMFIX]

I am not sure how the tire pressure monitoring system plays a role here but I would check the connections at the battery and look for damage. It seems really strange that after 2 the vehicle doesn’t start, how and who tested this battery? I could be a ibs issue but honestly I have to ask myself why is always successful in starting with just a jump start? It’s because the only power source when the vehicle is off is the battery. If you battery is new and this keep happening I would then suspect the alternator. Let me know what happens and good luck

[@maryannmartin2947]

I'm not sure either why it always starts with a jump start but it's so frustrating having a car that's constantly going flat, I will have another look at the battery but to my knowledge it seems to be fine. I'm based in NZ, a Auto electrical shop tested the battery with a battery tester? Lol they said it was fine. I only suggested the tyre pressure monitor because there is something draining the battery fast and causing it to go flat very fast.

[@maryannmartin2947]

Also only when the car is turned off and either the doors are opened or the car is in the on position but not started , then the car will go flat in like 2 mins.

[@RANDOMFIX]

Yeah, it seems like a battery issue, as there are few items that can drain a proper Bmw capacity battery in 2 minutes. You need to load test the battery. How old is the battery? You need to replace it with exact agm battery with the same exact capacity as it came with from factory or you need to program the new battery for your bmw vehicle.

I would do the following once you have put your battery battery tender with the vehicle is locked. Once you battery is charged on the battery tender for 24 hours I would pop the trunk, lock the doors using the remote with the trunk open. Wait one hour and unplug the negative battery post to drain all power to all the modules (computers) . After an hour I would reconnect the battery and reset time, etc...

So if it is the IBM sensor, can you do it on your own or do you take it to any Mechanic or just the BMW dealership?

Any mechanic that has scan tool that access bmw side of the any trouble codes, even smaller shops have them.

Okay hello, so I have a 2008 bmw 328i coupe & I changed the alternator, battery, and I took it to the car wash and the car completely died and the windshield wipers came on & then I took out the ibs and connected it back now my car keys won’t even recognize the car and nothing turns on at all except the light near the sos above plz help I’m so confused and I just brought this car from somebody

[@RANDOMFIX]

Why did you change the alternator and battery? Disconnect the battery ( check the voltage) and try reconnecting it. Do you access to scantool?

[@GoEatSum]

@@RANDOMFIX honestly I think it’s the b cable positive in the fuse box kuz my car had a recall on it and I think that’s the issue

[@RANDOMFIX]

If you recall in the video I should you how to bypass the cable and use jumper cables to trouble shoot this issue.

You don't need to disconnect the cable. Just pop the trunk before you start your engine. That will disconnect the signal to the ibs.

[@RANDOMFIX]

Really? Can you explain, thank you so much, I really want to understand.

Worked for me just now thank you!! I thought I was going to have to tow my car and I just opened the trunk and it started right up!

[@RANDOMFIX]
