It's European engineering in general and there's a reason. European labor is expensive, particularly in the West, and often hard to find for repetitive assembly jobs, so they try to automate as much as possible. Because there's limitations of what a robot can do, this means putting 5 snap-together plastic pieces to avoid two screws.
LaterMeansBrick were you looking at the window regulator? In my e46 the regulator looks so confusing and there are a bunch of other random parts in there as well besides the speakers and airbag. It may not be so modern anymore but everything still works as well as my parents newer chevys and fords xD
@@vincentlamb3436 Agreed, there is actually some Chinese stuff that's higher quality. OnePlus for instance makes some of the best phones around at a reasonable price. Mine (7T Pro) has proven to be decently durable, just as powerful as it's Samsung counterpart (S8), and unlike other manufacturers it's not filled to the gills with bloatware that you can't remove. Pricewise the 7T Pro is a bit cheaper than the Galaxy S8 but offers the same Processor, same RAM, and more storage per dollar. It also doesn't have a notch for it's selfie camera but instead uses a popup camera and it was the first phone with an under the glass fingerprint sensor which unlike Samsung's version never suffered from a certain major security flaw (if you used a screen protector anyone could open your phone). On the flip side it doesn't have SD card support (Mine has more storage than I'll ever need so that's not an issue), doesn't have wireless charging (the next version probably will but it's an overrated feature anyway as even 'fast' wireless is only half the power of 'fast' wired and is effectively worse than half when charging a phone that's still on and using power), and it doesn't have a waterproof rating (it's decently waterproof but the popup selfie camera probably introduces a potential water path). Admittedly I don't know what kind of shortcuts they may have taken inside the phone but from a usage perspective it's a good deal. Other than OnePlus I've heard there are some Chinese clothing manufacturers that focus on quality but I don't know of any brands off hand (I'm a simple man who doesn't shop for clothes very often and when I do it's usually just Hanes, Dickies, and occasionally Wrangler clothing though their quality seems to have dropped recently). When it comes to equipment and automotive manufacturing I don't think I've ever seen good quality from China (working in the manufacturing industry I've seen some stuff come from China that's made me wonder how the heck they screwed up so badly).
BigClive is another in the long line of folks who live to goof on technobits and spread the wealth of his understanding and his mad skillz at extracting clue from reluctant hardware. Once upon a time, this was how a good tech would troubleshoot kit they had never seen before. The advent of SAMS Photofacts for televisions and radio things were immensely valuable and a subscription to SAMS was a litmus test to distinguish a real repair shop from someone financing bass boat payments after the $DAYJOB. I will say that the mainstreaming of color television made a lot of money for SAMS because swapping a color picture tube with the requisite complete setup of convergence, purity, color levels, video drive, sweep geometry, and HV could become a real snipe hunt without the Tech Notes in the SAMS for the set in question. One could certainly get it done without the Cliff Notes, but a 2 hour job could easily become a 4 hour job, especially if using a “rebuilt” picture tube.

So, if you drive a BMW against another BMW, it's just the impact that's killing you - not the parts of the BMW that are malfunctioning. So you got that going for you, which is nice.

Going by my knowledge of german car electronics, the third wire was probably a K-Line (perhaps KWP2000) bus: the low-speed, one wire, bidirectional bus which was pretty much succeeded by CAN in the car. It's still in use in some areas of modern cars, mostly for sensors and actors like this one, which don't deserve access to the CAN bus. The seonsors are instead connected to "larger" ECUs which communicate their findings on the CAN bus (after some processing). That said, due to the pulsing communication, it does look a bit like a PWM signal.
nice video. Im a mechanic from Denmark, so i found this very interesting. In future experiments most of electric car components are wired with 12v, ground and a 5v signal. Hope you could use this in any way:)
It's amazing how i love your videos and i only understand 5% of the explanations... but i keep watching until the end. Maybe because my mind is always waiting for things to go wrong ;)
This is good stuff right here. Yeah it's too bad most modules these days require data to run. I don't know if it's always serial data, like via a CAN bus, but i do know that sometimes their "language" and/or protocols are proprietary. This means only their own modules, like a BCM, can talk to each other. Also that's only if they're programmed properly. Meaning you can't always swap the same hardware between the same vehicles either without being properly reflashed. Very frustrating.

actually there 6 cylinder engines are known to last a long time... we have 10 B.M.W'S in our yard we work on them ourselves ... vary in age .. mostly E36 +E46 .... If you know how to work on cars and have a shop.... and have a chance to own 1 of these cars .. you will know what all the fuss is about... usually people who dont work on their cars or have never owned a beemer who bitch about them... E46's are a excellent investment right now ..
@@lsd25records The E46 is an over 20 year old design, and even though I will personally always prefer pre-2000 cars, that is not what you could call "modern german car". A lot of the beemers from this decade are not quite as good.
30 ecus in a car is just silly ( I think Mercedes are even worse if you take the car battery out you then need to call Mercedes to come out and reconnect all your ECU features back up witch takes about 30 minutes to do)
Don't worry about blowing it up. Automotive components need to withstand - 100VDC pulses in testing, as well as other kinds of under- and overvoltage scenarios.
Well Joy-Joy for getting it running, several years ago I was asked to fathom an Eberspacher ... there's a £800 free standing set or 2 for £150 that are for polar regions and snap into skoda/Volvo/ect and the dodgy supplier throws in a hand drawn note as a wiring diagram... but I had no joy .. perhaps you would have fared better...
Overly complicated = typical BMW. Also it's so refreshing to hear someone pronounce solder the way it looks, I don't get what my fellow Americans were thinking when they decided they would say "sodder" instead.

Hi, Great VIdeo! BMW uses a number of communications standards to talk to the various modules its cars, but I think this device uses a system called IBUS (sometimes KBUS) . This is a single wire bus that in its quiet state is held at 12V by a resistor (aprox 10K). When a device wants to communicate it pulls the bus wire to zero volts using a UART at 9600 baud to modulate the signal. This as you found out is a little difficult to emulate with a bit of wire tapping on the gnd. :) . If you wanted to take this further then I would suggest using an arduino or raspberry pi's to operate a transistor that will pull the bus to ground as the uarts signal goes high. There's lots of stuff on the internet about how to format IBUS messages.
now i'm wanting to scour a junkyard for a couple of these modules to hack a bit and retrofit into a Ford F150 and a Jeep Cherokee, pretty sweet vid, cool video to watch
Car electronics are a fun rabbit hole if you're interested in how convoluted automakers have made components for convenience's sake. And then there's GM's OnStar CAN Data bus and a whole other can of worms to open up if you wanna get further
Nifty little device👍 I would love to have an Ionizer in my car, but I probably won't be able to afford a BMW in the near future, but maybe I can somehow incorporate a functional ionizer in my Citroën Berlingo👍
The 'spacers' are just glue dots to hold the component and secure it against vibration and cracking the solder joints. Not uncommon for larger SMD components.
I really love how you show that things can be used in other ways! Now I can't wait to find a unit like that and try to make a home air sanitizer from it! Could that be adapted to sanitize masks, maybe?
The 3rd pin will be a can line. One of my colleagues is am auto electrical genius and explained how they work. You have a 12v/14 ignition positive a can high at 2.5v and a can low at 2.5v when the bcm tells it to switch on it communicates with the controller and then sends back a message signal back to the bcm saying I'm gonna switch on as soon as I see ground. To then switch off the bcm momentarily cuts the +12v and makes the neutral become a can low again, the ioniser then says back to the bcm I'm switched off now and the cycle begins over
I wonder how often, and for how long this thing runs in an actual vehicle. I wonder if there's some sensor in the system that detects particulates and pumps in some ozone. Seems a bit excessive, but... whatever. I will say, I got a 1992 325is in early 2000's and drove that thing for about 8 years. Previous owner treated it like crap, but it was still a great car. I drove it to over a quarter million miles before finally deciding to get something newer. Strangely, it was actually the easiest car to work on that I've ever owned. Oil changes were especially quick and easy. I would have kept it, but the parts cost alone for the new shocks and struts it needed would be more than the entire car was worth. 😔
@@user-gx6jb6wc5g If you go to your Stealer it probably is. But if you are smart and buy parts else where its not bad at all. Had my E39 for 10 years now, still loving it.
@David Yeah, I'm in North America. Some general maintenance parts really weren't all that expensive compared to more common cars. Even replacing my radiator, (myself) was less than $100 if I recall correctly. The suspension, though.... that's where it really went into crazy cost territory. And by crazy cost, I think it was something around $2000 for all the parts, plus it would have required tools I don't own. I believe that car, at the time, with so many miles only had a Bluebook value of $2500 in top condition, so it really didn't make sense for me to do those repairs. It was a bit of a shame, I really loved that car. Although, I now drive a 05 Jeep Grand Cherokee that was a single previous owner that took great care of it, and it's also been treating me very well. I just wish changing the oil on it was half as simple as it was on my e36!
The single wire communication bus aka Local interconnect network. floats the line at a set voltage usually 5 volts and pulls it to ground. I still don’t think you could trick it even then, but figured I would toss my 2 cents in.
The connector on the unit is most likely Ground, Power and LIN bus. A LIN bus is a multi-drop serial bus, usually 9600bps, but can be up to 19200 bps. So you need to make some experiments with LIN bus devices.
I don't know anything specific about these ozone generators, but generally speaking as an auto tech, BMW sometimes uses single wire networks for their low bandwidth, low priority components. In that case, it would not just be a simple pwm signal that it was expecting, but actual communication. Ultimately it depends on whether or not the fault detection is only "ozone generator fault" or it it can store faults for all kinds of issues.
A common problem with car ventilation systems is that the cycling on and off of the air conditioning can lead to condensation buildup on the evaporator coil, and growth of mould - leading to a foul odour coming from the vents. I assume the ozone generator is mainly to tackle this issue, so disassembling half the dashboard to clean it out won't be required.

A lot of money goes in marketing and other bullshit while technical development is outsourced to save money.
actually there 6 cylinder engines are known to last a long time... we have 10 B.M.W'S in our yard we work on them ourselves ... vary in age .. mostly E36 +E46 .... If you know how to work on cars and have a shop.... and have a chance to own 1 of these cars .. you will know what all the fuss is about... usually people who dont work on their cars or have never owned a beemer who bitch about them... E46's are a excellent investment right now ..
@@lsd25records The E46 is an over 20 year old design, and even though I will personally always prefer pre-2000 cars, that is not what you could call "modern german car". A lot of the beemers from this decade are not quite as good.
Holy fuck you fucking killed it
Clive has found his niche , making really good videos !
I've literally never heard of such a device in cars. Granted I've always had older sports cars but this is intriguing
30 ecus in a car is just silly ( I think Mercedes are even worse if you take the car battery out you then need to call Mercedes to come out and reconnect all your ECU features back up witch takes about 30 minutes to do)
Don't worry about blowing it up. Automotive components need to withstand - 100VDC pulses in testing, as well as other kinds of under- and overvoltage scenarios.
That trick where you banged the board on the table to remove the solder was so clever.
Big Clive trying to emulate a high frequency signal from a BMW ECU by physically *quickly* tapping a wire on the contact.
You crack me up! 😃
Yeah, I was hoping it might be simpler circuitry.
Well Joy-Joy for getting it running, several years ago I was asked to fathom an Eberspacher ... there's a £800 free standing set or 2 for £150 that are for polar regions and snap into skoda/Volvo/ect and the dodgy supplier throws in a hand drawn note as a wiring diagram... but I had no joy .. perhaps you would have fared better...
I don’t even understand anything this guy is saying but it’s 4 am and I’m intrigued
One of my favorites ozone videos
"Lets try and... hot wire this thing." ...caused me to involuntarily slow blink and giggle.
Joyriders: "Let's hotwire this car!"
Big Clive: "I'm not going to hotwire the whole car, just the ozone generator."
"Its quite a big hole in there..... and then bang it"
- Big Clive, June 2020
"The spicy one." That needs to become a technical term
Totally learned a new method to clear solder from holes... Can't wait to try this in the office!
Great video! Minor comment: I think this is a Dielectric Barrier Discharge (or DBD), and not a corona discharge.
Overly complicated = typical BMW. Also it's so refreshing to hear someone pronounce solder the way it looks, I don't get what my fellow Americans were thinking when they decided they would say "sodder" instead.
Great video Clive, one of my favorites so far
I always wonder who put thumbs down on your videos...what's not to like..actually I don't waste my time wondering just find it wierd..anywhoo have a great day Mr Clive sir cheerios
Over-engineering? From BMW? Who'd have thought it!
Or are people confusing over-complicating with over-engineering. BMW and JLR are proving so unreliable in tests. Thats not engineering.
Hi, Great VIdeo! BMW uses a number of communications standards to talk to the various modules its cars, but I think this device uses a system called IBUS (sometimes KBUS) . This is a single wire bus that in its quiet state is held at 12V by a resistor (aprox 10K). When a device wants to communicate it pulls the bus wire to zero volts using a UART at 9600 baud to modulate the signal. This as you found out is a little difficult to emulate with a bit of wire tapping on the gnd. :) . If you wanted to take this further then I would suggest using an arduino or raspberry pi's to operate a transistor that will pull the bus to ground as the uarts signal goes high. There's lots of stuff on the internet about how to format IBUS messages.
16:20 - Interesting vandalous technique. I shall copy that
BigClive: How to Hotwire a BMW...
Ozone Generator
Epic click bait title! 😆😎
He totally should have made the title some variation of this!
now i'm wanting to scour a junkyard for a couple of these modules to hack a bit and retrofit into a Ford F150 and a Jeep Cherokee, pretty sweet vid, cool video to watch
Car electronics are a fun rabbit hole if you're interested in how convoluted automakers have made components for convenience's sake.
And then there's GM's OnStar CAN Data bus and a whole other can of worms to open up if you wanna get further
I like all your ozone-related videos very much.
Nifty little device👍
I would love to have an Ionizer in my car, but I probably won't be able to afford a BMW in the near future, but maybe I can somehow incorporate a functional ionizer in my Citroën Berlingo👍
The 'spacers' are just glue dots to hold the component and secure it against vibration and cracking the solder joints. Not uncommon for larger SMD components.
Oh no. He said Corona! Demonetized! :-P
Great video. It's amazing how much mad technology gets squashed into a European Car.
Please do the inner workings of a induction cooker and how the temperature is controlled.
I really love how you show that things can be used in other ways! Now I can't wait to find a unit like that and try to make a home air sanitizer from it! Could that be adapted to sanitize masks, maybe?
You can buy ozone generator modules on eBay. Be aware they operate at high voltage, though.
The 3rd pin will be a can line. One of my colleagues is am auto electrical genius and explained how they work. You have a 12v/14 ignition positive a can high at 2.5v and a can low at 2.5v when the bcm tells it to switch on it communicates with the controller and then sends back a message signal back to the bcm saying I'm gonna switch on as soon as I see ground. To then switch off the bcm momentarily cuts the +12v and makes the neutral become a can low again, the ioniser then says back to the bcm I'm switched off now and the cycle begins over
I wonder how often, and for how long this thing runs in an actual vehicle. I wonder if there's some sensor in the system that detects particulates and pumps in some ozone. Seems a bit excessive, but... whatever.
I will say, I got a 1992 325is in early 2000's and drove that thing for about 8 years. Previous owner treated it like crap, but it was still a great car. I drove it to over a quarter million miles before finally deciding to get something newer. Strangely, it was actually the easiest car to work on that I've ever owned. Oil changes were especially quick and easy.
I would have kept it, but the parts cost alone for the new shocks and struts it needed would be more than the entire car was worth. 😔
I believe it's one of the most expensive cars for parts.
Would not surprise me lol
@@user-gx6jb6wc5g If you go to your Stealer it probably is. But if you are smart and buy parts else where its not bad at all.
Had my E39 for 10 years now, still loving it.
Given the power I'd bet it probably just puts out a burp of O3 now and then, maybe tied to fan speed to keep the level in the cabin fairly constant.
@David Yeah, I'm in North America. Some general maintenance parts really weren't all that expensive compared to more common cars. Even replacing my radiator, (myself) was less than $100 if I recall correctly.
The suspension, though.... that's where it really went into crazy cost territory. And by crazy cost, I think it was something around $2000 for all the parts, plus it would have required tools I don't own. I believe that car, at the time, with so many miles only had a Bluebook value of $2500 in top condition, so it really didn't make sense for me to do those repairs. It was a bit of a shame, I really loved that car. Although, I now drive a 05 Jeep Grand Cherokee that was a single previous owner that took great care of it, and it's also been treating me very well.
I just wish changing the oil on it was half as simple as it was on my e36!
The single wire communication bus aka Local interconnect network. floats the line at a set voltage usually 5 volts and pulls it to ground. I still don’t think you could trick it even then, but figured I would toss my 2 cents in.
Yeah, I would think you'd need the whole car to monitor the line for a while and see what all it expects to see.
Broken_Yugo leave it to da Germans lol
you had me at external stimulation, thanks for keeping us entertained!
I love you, bigclive. You remind me of my lectures with Mr. Guerin
Big Gear or Top Clive?
The grand Clive?
Top Clive or Bottom Clive?
Why not both?
Lmfao
Neat, impressive hacking Clive. Cheers
The connector on the unit is most likely Ground, Power and LIN bus.
A LIN bus is a multi-drop serial bus, usually 9600bps, but can be up to 19200 bps.
So you need to make some experiments with LIN bus devices.
i could have sworn this was scott manley for a second before looking at my other screen. holy hell
The control wire is possibly CAN bus allowing the unit to talk to the car, and vice versa.
another ripper episode. this one was particularly impressive. good on ya big clive.
This was much more fun than it had any right to be.
The 32 pin QFN device is an Atmega88-15MZ, the same family of 8 bit micros used in the original Arduino.
Maybe that ceramic plate needs to be introduced to the stun gun module...
I don't know anything specific about these ozone generators, but generally speaking as an auto tech, BMW sometimes uses single wire networks for their low bandwidth, low priority components. In that case, it would not just be a simple pwm signal that it was expecting, but actual communication. Ultimately it depends on whether or not the fault detection is only "ozone generator fault" or it it can store faults for all kinds of issues.
Alright, my question has been answered, it's made by Paragon AG.
After reverse engineering a few myself (including the gfci outlet video on my channel) I have to agree.
You can use an LCR meter to differentiate the transformer windings.
A common problem with car ventilation systems is that the cycling on and off of the air conditioning can lead to condensation buildup on the evaporator coil, and growth of mould - leading to a foul odour coming from the vents. I assume the ozone generator is mainly to tackle this issue, so disassembling half the dashboard to clean it out won't be required.
Good work. I was making breakfast when you hacked it so I'll have to watch again.
Maybe the input is not PWM but LIN bus?
Oooh, very mikeselectricstuff like! I like this style very much! I would really be cool if you'd reverse engineer and disec more exotic stuff too, on top of the usual ebay chinesium. Great Vid!
gramps, you totally made me fall asleep - short story on how: after jogging and shower, found this recommandation from, JJ, EWtube and found myself with a neck pain cause I fell asleep like in a car
and I thought Freeman, Cain and Hopkins make you fall asleep but looks like big gramps can also. thanks! the nap helped so you got a like, dont care what you talk about in the video so much but the like is for the nap - "good speed" if exist such thing
had to edit cause am still sleepy from
there is probably more electronics in that one circuit than a 1960's morris minor or VW beetle!
Welcome to another instalment of rip it apart Clive. i have a mate like you, he tells me he fixes thing but what really happens is, he rips it apart throwing the screws over shoulder, figures out how it works then it goes in his scrap box, well i say box, massive shed.
But i do like your videos.
The entire world: we have the wheel,a perfect and simple circle
Germany: we can redesign and over complicate it
Customer: Build in an ionizer air freshener that's the most complicated and has a swollen BOM.
BMW: Hold my schnitzel
I have no clue what this guy is taking about most of the time.why do I find this channel so watchable?????😳
james may would love this man.
my yt ai is just giving me alot of you tonight for some reason. : o D also really fun bumblegum techno music shuffle comps as well. ive really missed this. sorry i was away for a while.
"not recommended"
