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.

@@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).

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.

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.

[@robcooper9265]

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.

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 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.

5:55 : that looks like a buck converter stage using the inductor of the current-fed royer converter. That's pretty typical for LCD backlight circuits.

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

Is this used to stop mould growing in the air vents thus making the AC smell bad? I cant think of any other reason for this?

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.

Hello, great description by the way, very thorough! Sorry though because i don't understand the point of doing this? Is this supposed to make the air fresher inside the car? Or are you just tinkering for the sake of seeing what happens?

I just wanted to explore the circuitry in it.

3:32 On the circuitry there is maybe a feedback to the CAN-bus diagnostics of the car.

16:20 - Interesting vandalous technique. I shall copy that

Could you figure out why the BMW M5 actuators fail? I have had 2 go bad but after looking inside couldn't find anything wrong with it.

I'm guessing there is some form of current detection which the microprocessor would use to limit consumption (max is supposed to be 830mA), but of course you bypassed all that.
