They all do that when the battery goes dead...Why I said he has a battery issue from the very start. As BMW and Mercedes Benz are notorious for it..Cadillac comes in second. As I seen people toss parts at them. All the while the battery is either shit or the Senor went out.. And you need that Sensor. The alternator relies on it. As the ECM controls the Alternator through the battery sensor...
Excellent diagnosis Ivan, just one issue. Having the battery sensor disconnected will effect the customers charging circuit, note if you run the motor without the IBS (intelligent battery sensor) charge voltage will default to 13.7v as it does not know if battery is empty or fully charged. Current will be around. 10-15amp which is not enough to charge the battery on short trips. If IBS is present and connected, charge voltage will go up to 15.2v and 80amps (for a fully discharged battery) or 12.1v for a fully charged battery. It would pay to replace the dead IBS to save his battery and not have his smart alternator working on limp mode all day. BMW won't throw any faults when IBS is disconnected except that it cannot see the IBS. Possibly something to mention to the customer. Anyways. Excellent work as always Ivan. Nop notch mechanic.
It's not just the voltage you have to worry about 13.7 may sound good, but your current will be limited. If your battery is at 50% capacity. IBS reports to ecu, ecu will then command alternator to up both voltage and amps. Charging can go up to 60amps and get you charged up quickly. Without IBS and at 10amps charge you will have to drive the car for 12hrs straight before you charge it to full capacity. Meaning you can never recover from a starting event and your battery will forever remain at 50% which lowers the capacity of your battery and destroys it quickly. So to save money on an IBS you will be going through batteries every 6-12 months.
I have a 2006 530xi wagon. There also are a whole bunch of small modules under the spare tire in a foam carrier in the spare tire well. There was a service bulletin to move all of the modules out of there and into the compartment on the driver's side rear of the car because of potential flooding.The cables are long enough and there is plenty of room in that compartment to move them pretty easily. No modifications to the harness or modules required. I used heavy duty Velcro to mount the modules in the new location.
Typical German design issue: 'this shouldn't happen, therefore we don't need to take it into account' Japanese philosophy: 'this HAS happened, therefore we MUST design to prevent recurrences'
They build these cars for wet environments. Just amazing they don't test them for it. Battery in the right rear wheel well just inviting owners to drive through the puddles.
(I'm at 20:00 minutes) The CAS Wakeup line is shorted to ground. This is a logic line, it shouldn't be able to light a 1A test light at all. The little spikes you see on the scope is the CAS trying to put voltage on the line, and shutting off after a brief period due to the short. The sleep timer for these modules is about 30s-1 minute, so you didn't wait for long enough.
Right, he realy simply did not wait long enough. I didnt know about the current that it should be able to draw but it sound plausible. PS: yeah now min 30, he found the culprit
Wake up to a new video from Ivan, just watched Eric's video yesterday you two are the BEST on RUclips at diagnosing electrical problems, what a great start to the weekend!!!!
I'd also highly recommend Wes's channel (Watch Wes Work), though most often he works on trucks/tractors, he did a good chunk of car diagnostics as well.
I've always wondered how to properly charge for diagnostic work. For one the tech could be spending hours barking up the wrong tree, is the customer liable for that? What's the middle ground here? Should one hour be enough to at least zero in on the issue ? How do you charge for diag?
@@Usmanthemecano Local shop used to charge $240 to park on their lot. Appointment only. That got customer 1:45hrs. Then they would call customer and explain what WASN"T wrong but needed more time.

Sensors will be reconnected (after repair/replace) on next trip to the dealer if that ever occurs. It's the dealer's 2nd line of revenue after profit from sale of vehicle.

I was just about ready to throw in the towel but then saw a faint wisp of smoke coming from the battery area after leaving the test light powering up that line for a while haha

Does it rain in Germany? I had an otherwise great Jetta years ago that leaked like a sieve. Convinced me to move the family entirely to Toyota. Never looked back.
Wow! Ivan you fixed this drenched mess in 3 hours. For me that would have been 3 years give or take a millennium. It reminds me of a Diagnose Dan that found a defective BMW passenger door latch that kept the whole car from starting. I think to fix these vehicles one has to Be More Wise (or in your case extremely patient).

Sideways rain partially filled my Promaster's front and back plastic lights boxes, break and turn signal light went out, some socket corrosion. Will drill some drain holes in the bottom of all 4 light boxes (inside the vehicle body) to allow the thing to drain if it happens again.
Actually, you will need that battery sensor replaced eventually as it will show a battery drain message on the HUD and the charging system won't work properly. But good catch. Those battery sensors are a common problem on BMW's.
Brilliant :-D, I like the precision pull up resistor lol. Sometimes you have to try dirty tricks. I've done some evil things with electronics, but i got the result i wanted :-D The line between Bodge and Pro Modification can be very difficult to see.
This happened to my phone once, i put it in a bag of rice for a few hours! Maybe try keeping a big bag of rice around for next time? Lol... I am obviously joking people! Great job as always Ivan! Im a little late to the party but just wanted to commend you on another great diagnosis!
Ivan!! Why are you so perfect? I have such a man crush 🤣😂. I have watched countless videos you’ve produced. I have found myself impressed by everyone! Then I hear you speaking Russian! May you continue to be blessed with success! Thank you for teaching us viewers so much!
how did you find the pin to wake up can? was it just one of Can's wires? and why in this module - did it matter where the Can bus was to wake up? regards
If you'd known more specifics about BMW's you'd have this diagnosed in 5 minutes. the CAS wake up line fault gave it all away. If the wake up is missing no modules will communicate on PT-CAN like DME, DSC, transmission control. This car has got the old Intelligent Battery Sensor design with a metal body. On the newer cars and on the replacement part for that IBS the whole body of the sensor is moulded plastic to prevent water intrusion. Very very common issue this ;)
if BMW put the fuse box in the driver footwell thats the only spot water enters, if they put it on the passenger side footwell it only leaks there. Even in the back thats the only place water leaks in!
I always wondered why you have a russian name and look russian, now it's confirmed. I am learning alot from you. Thanks for dedicating your time to making these videos.
Awesome job! I still own a Diesel E60 here in the UK and I've had previous with that sensor before. It's clever how it works but overcomplicates things bearing in mind most of these cars have standard flooded lead acid batteries! I hope you both toast victory with some Russian vodka 😁
The back area fills up because the sunroof drains get clogged and the water has to go somewhere. It happened to my MB MLxxx - somewhere between 11 and 14 gallons were drained out and insurance paid for a total loss from all the electronics in the back and under the passenger compartments carpets being soaked during a heavy rainstorm, a few days after a dealer maintenance service visit.
@@miscbits6399 In looking at the itemized service reports, blowing out the drain lines on the MBs with sun roofs is not on the list of service items. If they had done it, it would have been an itemized charge of over $150. I blame MB for designing a crappy, inadequate drain system and not instructing dealers on proper maintenance intervals and procedures. From my service adviser, I gathered it was a common problem in my area - only one customer of that dealership had ever insisted on having his insurance company pay to have his vehicle completely repaired by fixing the drainage lines and replacing everything that was water damaged, well over $40,000 worth of parts and labor on a vehicle with an MSRP of over $65,000, and more for more expensive models. I now drive my old Ford F150, which never leaks or breaks down.
Please do a follow up on the “why” a battery sensor caused this. Also why that sensor is even used. And what could happen without it??? I’ve seen them missing,bypassed and reengineered without a customer complaint. Again, let us know the BMW nonsense behind this sensor. Keep your videos coming👍👍
Pine Hollow/Ivan, you rock! UPDATE 12-13-21: after listening better I noticed DCM, TCM, etc mentioned... now can follow better. None of the modules ACRONYMS you mentions are in my GM/Chevrolet dictionary(compiled by me, lol) which speaks in ECM,BCM,TCM, etc... So I am struggling trying to follow the logic. ...thru your videos, it has become clear to me that the scanners are of great help, but having schematics and the logic behind all the circuitry is very much critical. My toy (Express 4500) also got annihilated by water due to super sloppy fleet maintenance, that left all distribution blocks without cover, wide open to the elements, + water leaks that were created by added equipment installations. I am getting the 1B+,16can, and 6can on my new breakout box and a slew of nocom with all the modules except the ECM... and a million errors that make no sense... and I suspect the nocom to the BCM/ECM has a lot to do with my click/IPC blackout?! noengineturn/nocrank situation... and this thing was cranking like a purrin' kitten for the longest time. The mechs also left dozens of stripped wires dangling all over the place, especially in the upfitter's T-Harness side where 2 extra distribution blocks live... could it be one of the circuits that limit cranking if handicap ramp or bus doors are not stowed is all the issue? ...what a clusterphck! I have to go thru the same steps you describe in a foreign language of ACRONYMS. LOL I am in pain.
I could spend a two week vacation at your place and Eric O’s just observing their diagnostic skills and lean more than I have in the last ten years. Then when you get electrical problem fixed you’ll have to find and repair the water leak.
I wonder if once you pulsed the wakeup line, the scanner was keeping modules awake since they knew they were being scanned. German cars seem to all have problems with the stupid rear modules, a friend of mine has a Mercedes with the same kind of thing, intermittent rear module due to water. I have been thinking there has to be some way we could better protect those boxes; maybe some kind of water deflector? Sealing connectors with silicone? Something.
@@adotintheshark4848 Some things we can't control, like when friends and family buy poorly designed vehicles against our protest (and of course are shocked afterwards when that 'minor issue' requires a $900 part). Believe me, I tried to talk them out of it.
Nice figuring that one out. When you had the car starting only with CEL on that made me laugh. I guess the moral of that is a BMW with out an illuminated CEL is really broken.
Wow, that was really weird diagnosis!! That's why i don't like BMW lol!! To many modules especially in the rust belt! They fail a lot! But glad there was outcome of the problem, battery sensor!!!
I like this tool, it is sized right... and presents data in a comfortable way. especially for less than $1K... but if it does not allow reprogramming of used or new modules... the savings in cost will quickly be wiped out.
That's the scary part with water incursion. It'll work fine and then oxidation will recur and the issue will be back. The only way to guarantee a fix to take apart that box and use deox it and a brass brush.
My BMW did the same thing, but nothing was wet. The fuel pump control module burnt out and shorted out the fuel pump as well. And The Control module was pulling down the wake up wire to 0v and it was on every module. It took me 4 hours to diagnose, I knew it had to do with something with the power Feed. Last year I replaced the battery and I noticed the sensor for the battery was unhooked I thought it was bad and it was I replaced the sensor as well. No more problems for now lol.
Hello ! Personally I don't recomend to go without IBS a very long time. Need to replace it. Try to find piece on FCP Euro. Lack of IBS can make more trouble than you think. Thank you.
First thing I was going to say was the IBS shorted out. Disconnect the blue connector on it and try starting it. They short out somehow in the rear fender sometimes or just go bad.
I can ordinarily keep up and follow along with a clear understanding of what is going on, but after watching this one a couple of times the only thing I'm sure I understand is that I don't understand German automotive electronic engineering, but nice work Ivan
Commenting while watching the first 5 minutes... How did the water get in there ? Did a sunroof drain hose come off the nipple where it exits at the rear ?
It has the P6666 - Code for get rid of it as its euro. Nothing makes sense on a euro... I paused it to comment I kept seeing the key on the DIC, is it not seeing the key? That scanner has live data right and if it has a comm to it see the PID brake switch. Dont forget the doors open close open close so the car goes to sleep?
LOL on the way to the junkyard... 5 years later still fixing it. as long as it starts and drives its not heading to any junkyard lol... bigger question is did he fix the leak so it all doesnt get wet again. good job especially staying away from chasing corrosion issues
Saturday morning PHD video and coffee. My brother was into aquariums. His only cost a few hundred bucks not a few thousand bucks. Do you have to be a certified scuba diver when you buy one of those. Great diagnostic and find my friend.
So this car will be driven until the wheels fall off... I bet he has no intention of junking it anytime soon... so what is the resolution on the water intrusion..thats really the first thing to fix... but nice diag, interesting

The line between Bodge and Pro Modification can be very difficult to see.
This happened to my phone once, i put it in a bag of rice for a few hours! Maybe try keeping a big bag of rice around for next time? Lol... I am obviously joking people! Great job as always Ivan! Im a little late to the party but just wanted to commend you on another great diagnosis!
Ivan!! Why are you so perfect? I have such a man crush 🤣😂.
I have watched countless videos you’ve produced. I have found myself impressed by everyone! Then I hear you speaking Russian!
May you continue to be blessed with success! Thank you for teaching us viewers so much!
how did you find the pin to wake up can? was it just one of Can's wires? and why in this module - did it matter where the Can bus was to wake up? regards
Look at that beautiful angle you can see the screen perfectly boy you are getting amazing! All the best in Canada
It's always hard on a sunny day...
If you'd known more specifics about BMW's you'd have this diagnosed in 5 minutes. the CAS wake up line fault gave it all away. If the wake up is missing no modules will communicate on PT-CAN like DME, DSC, transmission control. This car has got the old Intelligent Battery Sensor design with a metal body. On the newer cars and on the replacement part for that IBS the whole body of the sensor is moulded plastic to prevent water intrusion. Very very common issue this ;)
It was a good learning experience :) I'm not a BMW specialist, but enjoy a good challenge haha
if BMW put the fuse box in the driver footwell thats the only spot water enters, if they put it on the passenger side footwell it only leaks there. Even in the back thats the only place water leaks in!
Volkswagon put the ecu under the carpet in the passenger footwell, then disclaimed responsibility for flooding issues
I always wondered why you have a russian name and look russian, now it's confirmed.
I am learning alot from you.
Thanks for dedicating your time to making these videos.
Awesome job! I still own a Diesel E60 here in the UK and I've had previous with that sensor before. It's clever how it works but overcomplicates things bearing in mind most of these cars have standard flooded lead acid batteries! I hope you both toast victory with some Russian vodka 😁
Amazing Diag. Congrats.
You're such a magician! Such surprises every time! Thanks for the great content!
The back area fills up because the sunroof drains get clogged and the water has to go somewhere. It happened to my MB MLxxx - somewhere between 11 and 14 gallons were drained out and insurance paid for a total loss from all the electronics in the back and under the passenger compartments carpets being soaked during a heavy rainstorm, a few days after a dealer maintenance service visit.
One would hope the insurers would then claw it back from the maintainer. It incentivises them to get their shit together
@@miscbits6399 In looking at the itemized service reports, blowing out the drain lines on the MBs with sun roofs is not on the list of service items. If they had done it, it would have been an itemized charge of over $150. I blame MB for designing a crappy, inadequate drain system and not instructing dealers on proper maintenance intervals and procedures. From my service adviser, I gathered it was a common problem in my area - only one customer of that dealership had ever insisted on having his insurance company pay to have his vehicle completely repaired by fixing the drainage lines and replacing everything that was water damaged, well over $40,000 worth of parts and labor on a vehicle with an MSRP of over $65,000, and more for more expensive models. I now drive my old Ford F150, which never leaks or breaks down.
Wouldn't isolating the battery sensor effect the charging system (if its a computer controlled charging system)? Good video Ivan.
It just measures the current. Will not affect.
Please do a follow up on the “why” a battery sensor caused this. Also why that sensor is even used. And what could happen without it??? I’ve seen them missing,bypassed and reengineered without a customer complaint. Again, let us know the BMW nonsense behind this sensor. Keep your videos coming👍👍
Get down Ivan 👍 good idea using the different bulb draws.
Yes the BMW! The Ultimate Driving machine! But won't work on a Battery sensor bad? What were they thinking? Great video!
Pine Hollow/Ivan, you rock!
UPDATE 12-13-21: after listening better I noticed DCM, TCM, etc mentioned... now can follow better.
None of the modules ACRONYMS you mentions are in my GM/Chevrolet dictionary(compiled by me, lol) which speaks in ECM,BCM,TCM, etc...
So I am struggling trying to follow the logic.
...thru your videos, it has become clear to me that the scanners are of great help, but having schematics and the logic behind all the circuitry is very much critical.
My toy (Express 4500) also got annihilated by water due to super sloppy fleet maintenance, that left all distribution blocks without cover, wide open to the elements, + water leaks that were created by added equipment installations.
I am getting the 1B+,16can, and 6can on my new breakout box and a slew of nocom with all the modules except the ECM... and a million errors that make no sense... and I suspect the nocom to the BCM/ECM has a lot to do with my click/IPC blackout?! noengineturn/nocrank situation... and this thing was cranking like a purrin' kitten for the longest time.
The mechs also left dozens of stripped wires dangling all over the place, especially in the upfitter's T-Harness side where 2 extra distribution blocks live... could it be one of the circuits that limit cranking if handicap ramp or bus doors are not stowed is all the issue? ...what a clusterphck! I have to go thru the same steps you describe in a foreign language of ACRONYMS. LOL I am in pain.
Great job boss please let me know wich wiring diagram you can use boss
I could spend a two week vacation at your place and Eric O’s just observing their diagnostic skills and lean more than I have in the last ten years. Then when you get electrical problem fixed you’ll have to find and repair the water leak.
I think you should buy this car Ivan.Just so you can play with it ,in your spare time .lol
NOOOOOOOOOO! 🤣
@@PineHollowAutoDiagnostics LoL 🤣😆
BMW: Buying Many Woes
@@PineHollowAutoDiagnostics Вот насмешил! Упаси бог!
I wonder if once you pulsed the wakeup line, the scanner was keeping modules awake since they knew they were being scanned. German cars seem to all have problems with the stupid rear modules, a friend of mine has a Mercedes with the same kind of thing, intermittent rear module due to water. I have been thinking there has to be some way we could better protect those boxes; maybe some kind of water deflector? Sealing connectors with silicone? Something.
How about BMW building a better vehicle in the first place..say, one that doesn't leak water? For what those things cost, it's inexcusable.
@@adotintheshark4848 Some things we can't control, like when friends and family buy poorly designed vehicles against our protest (and of course are shocked afterwards when that 'minor issue' requires a $900 part). Believe me, I tried to talk them out of it.
@@jessicav2031 especially when poorly designed vehicles are in the BMW price range.
Nice figuring that one out. When you had the car starting only with CEL on that made me laugh. I guess the moral of that is a BMW with out an illuminated CEL is really broken.
just curious how it was charging after the sensor was removed. did the computer go into a default strategy for charging?
My thoughts exactly.
I think i read a comment to the effect of he doesn't know and doesn't care...i tend to think it matters
Ivan that was amazing! Well done. I enjoyed this case study.
Good job :D
Bit concerned the Voltage, Terminal 15, Wake Up (ACC) is staying low - 0.13V at 32:42
Maybe something on that tree got flooded out too?
No idea...customer was only concerned with the no-crank situation :)
Good find and great diag!
I would love to see what equipment you take on each off sight diag ? tools and equipment ?
Wow, that was really weird diagnosis!! That's why i don't like BMW lol!! To many modules especially in the rust belt! They fail a lot! But glad there was outcome of the problem, battery sensor!!!
Good diagnosis skills
Good one! Thx! Pays to try and keep it simple.
I like this tool, it is sized right... and presents data in a comfortable way. especially for less than $1K... but if it does not allow reprogramming of used or new modules... the savings in cost will quickly be wiped out.
That's the scary part with water incursion. It'll work fine and then oxidation will recur and the issue will be back. The only way to guarantee a fix to take apart that box and use deox it and a brass brush.
First time I heard you speak Russian! Awesome. And I understand you well.
were did all that rain water come from? through the car wash with the hatch open?
Another awesome job and video thank you!
My BMW did the same thing, but nothing was wet. The fuel pump control module burnt out and shorted out the fuel pump as well. And The Control module was pulling down the wake up wire to 0v and it was on every module. It took me 4 hours to diagnose, I knew it had to do with something with the power Feed. Last year I replaced the battery and I noticed the sensor for the battery was unhooked I thought it was bad and it was I replaced the sensor as well. No more problems for now lol.
Hello ! Personally I don't recomend to go without IBS a very long time. Need to replace it. Try to find piece on FCP Euro. Lack of IBS can make more trouble than you think. Thank you.
I am curious if you have a OBD breakout box. I think you would seen the problem at the box.
What would you see on the box?
Well done, great fix.
First thing I was going to say was the IBS shorted out. Disconnect the blue connector on it and try starting it. They short out somehow in the rear fender sometimes or just go bad.
@@JayDee-b5u Usually it's the starter after that.
Badass diag and repair sir. Thanks Ivan!
I can ordinarily keep up and follow along with a clear understanding of what is going on, but after watching this one a couple of times the only thing I'm sure I understand is that I don't understand German automotive electronic engineering, but nice work Ivan
The lack of good information plus the over-complicated wiring and logic make Euro diagnostics a special experience haha
I've seen enough German engines torn down on I Do Cars' channel to know that they do everything in the most complicated way possible.
Commenting while watching the first 5 minutes... How did the water get in there ? Did a sunroof drain hose come off the nipple where it exits at the rear ?
It has the P6666 - Code for get rid of it as its euro. Nothing makes sense on a euro... I paused it to comment I kept seeing the key on the DIC, is it not seeing the key? That scanner has live data right and if it has a comm to it see the PID brake switch.
Dont forget the doors open close open close so the car goes to sleep?
LOL on the way to the junkyard... 5 years later still fixing it. as long as it starts and drives its not heading to any junkyard lol... bigger question is did he fix the leak so it all doesnt get wet again. good job especially staying away from chasing corrosion issues
Saturday morning PHD video and coffee. My brother was into aquariums. His only cost a few hundred bucks not a few thousand bucks. Do you have to be a certified scuba diver when you buy one of those. Great diagnostic and find my friend.
Thanks Bill :)
OMG a BMW and Water!!! Junkyard will not even take it...you will need to fixit Ivan!
What scanned tool are you using? Would it be good for a DIY?
This reminds me of Diagnose Dan's "No start because of doorhandle!" BMWs are as fragile as 1mm thick glass windows.
I just remembered the same diagnose Dan episode too. I think Break My Wallet is a good moniker for the car.
Wow! Great diagnostics, Ivan! On some cars, there's just not enough chickenblood and virgins to sacrifice and make it work.
So this car will be driven until the wheels fall off... I bet he has no intention of junking it anytime soon... so what is the resolution on the water intrusion..thats really the first thing to fix... but nice diag, interesting
Great job Ivan . well don
Good job Ivan! Is the Battery Sensor repairable? Is it worth replacing?
Don't know and don't care haha
It would be smart to replace it, it most certainly was designed to perform a specific function
In addition to a BMW sensor, Hella makes a replacement at considerably lower cost and with a connector harness that is replaceable.
So ... a BMW can run just fine with 1/2 of its sensors and fancy electronics disconnected? Got it.
... kinda sorta
I was gonna say, hook it up to ignition for temporary signal ;) nice find
Dynamic Stability Control (DSC) The Dynamic Stability Control (DSC) automatically controls braking and engine torque in conjunction with systems such as ABS and TCS to help control side slip when driving on slippery surfaces, or during sudden or evasive maneuvering, enhancing vehicle safety.
Eric O. to the battery sensor - What do you want me to lady, chop it off? Lol
Hey Ivan, had your scanner ever give the code " hren evo znaet"? :)
xD
Very nice sharing
I knew you speak Russian! This is the only video that proves it, I've been wondering for a while lol
I understand most of it. Awesome work. I know, this video is 2 years old now. Haha
Never Forget. I remember seeing the smoke from the Pentagon from work
The airplane no one ever seen... Yeah ok
Aw crap! We’re getting infected with the loonies.
I realize you all like to keep your wounds open and stinging, but is there anywhere left to avoid these reminders and the inevitable loonies?
And they found the 'arab' passports in the smoldering wreckage...and 2 planes brought down 3 buildings in NYC...and....blah blah blah....now we got the "patriot act"...and even later we got the covid 'vaccine' mandate...yeah sure.
@@aday1637 WTC 7: Pull it.
Really surprised that 4v was enough to wake up the CASS. But anyways, I know that b+ sensors are known to cause havoc on Merc and Audi's. I guess I'll add Beemers to the list... Great job!
That was great Good job.
Niceeee job Ivan your a Monster👍
Hello when you bought a thinkcarpro scan bi direction how it work for you did you pay for every car you work on it or it work just like other
Very Cool thank u sir👍
IBS SENSOR CABLE, BLUE DOT PLUG. Price 138.00, or just unplug it, car starts, runs fine. My second one just went bad, not buying another one. 2007 BMW 328 XI.
Exelente gracias
The ThinkTool looks pretty awesome, but damn.... that "Pre-repair" save option placed after the "Post repair" button drives me crazy.... Pre comes before post, put the damn buttons in order dammit! LOL
The people who programmed it don't read text in that direction.... ;-)
The Hindenburg collides with the Statue of Liberty and crushes the Titanic:
- Ivan: "Now this is _really_ cool!"
You are very....VERY,,,GOOD !!
