Very good! As my parents always said no one can take away an education. Besides if you enrolled in most mechanic programs in this country few would give the detail of Ivan or Eric O.
This is why I watch, I might pick up some little tidbit that will help me down the line as well as general knowledge. I'm retired and finally have time to do some automotive learning, since I have always been my own mechanic.
@@Paramount531 This is me too. I've been retired for over five years now and have been studying this stuff for the past three years. I've learned a lot and have a lot more to learn.

@@calholli Well with the cost rise and that silicon chips aren't as cheap or abundant anymore. We may see regression in this, not as far as the Russians have to do with their cars, but you may get simple setups again if this keeps up.

Ivan, That's why it's so cool to have you here with us. Not only that we all know you'll do "almost" anything to make customer satisfaction. You are the man...Pete
It would have been interesting to try an turn off the bit's in the original door module one by one, to see if the draw went away. Another great video , Ivan !
Hi Ivan! At the coding part, each octet or slot you were referring are actually just hexadecimal numbers for the binary digits, what you can edit. Each "slot" in the long code has 1 byte of space, that is 1111111 in binary or FF in hexadecimal. You can set each extra-option like heated mirrors and such with a single bit like 0 or 1, then it's convereted to a hexadecimal number, to fill the slot/ocetet in the long code. In this case it was 01011110 to 5E. Good video as always!
I will also add that for binary to hex, split it in 2 groups of 4 bits. 01011110 = 0101 1110 Now, each position is worth: 8 4 2 1, so you have 4 and 1, that make 5 And 8 4 2 = 14, for 10-15 you use letters, A B C D E F... 14 would therefore be E Which make 5E
Typically, each byte is 8 bits . you used 7 in the first example and 8 in the second. I know....but being a good programmer, or auto diagnostician, you have to be a bit obsessive compulsive OC.
Great job Ivan finding the problem but the curious part of me wanted to see if the door module coding change fixed the mirror functionality. I really wanted to see the mirrors fixed too. Almost a cliff hanger!
Since the problem began after the damaged mirror it probably still won't work BUT the damaged mirror might play havoc on the replacement module. Perhaps repairing or replacing the mirror could be the ultimate repair.
I was wondering that also. The 'new" module was showing no DTCs but the mirror movement wasnt commanded. Would have been interesting to see what would happen during the special function test mode...
How can something with that many circuits, modules, sensors, connections, etc... honestly be reliable? Simple (usually) equals reliable. That thing is a rolling bag of service calls! And if that isn't bad enough, the new Mustang Mach E has an extra mile of wire it doesn't need! The design trend nowadays is toward failure rather than reliablity! Great diag, Ivan! 👍
I do wonder if there is a more precise way of locating an issue such as this on an EV? I think of what a Tesla must be like when it drives itself for the most part? It is a nightmare being a closed repair ecosystem.
It would be interesting to see where they invested all that extra copper considering weight and cost being a factor. I have to think it was invested in redundancy for safety but I've been wrong before and will be again.
@@InsideOfMyOwnMind I hear that the wire adds an extra 300lbs to the already "heavy as hell" car! You don't save energy or anything else by adding 300 needless pounds!
@@basshunter428 300lbs is insane. I would like to see somebody come in here with some actual facts about the car because so far it sounds like we're all kind of doing hearsay. No disrespect.
Coding in VWs (and Audis etc by extension) is pretty amazing. You want to install some heated mirrors? If you install the OEM stuff you don't need a new module. Just change the coding, and the car knows. Want to use a module from a car with different options? Also no problem, just change the coding to match your old module.
Another great job Ivan. I was hoping that you would open up the module (I'll be that you did) so we could see if this was another module taken out by water intrusion.

Ivan I would like to make a request. You are a busy guy so this may be a bit much to ask. Would you consider doing a video on the Pico 4 channel (or some alternatives like you showed here) and the accessories that you find most useful. This could include the physical items you use with your scope as well as the best wiring diagrams be it Alldata or Mitchell. Many of us could save our cars from the junk yard as you do. Some people say a $4K scope is way over the small garage mechanic or the home mechanic. I would say if I can save a $40K to $70K car or truck from having to be purchased I have done my job. Also since many mechanics are parts changers some people could leverage this to a part time job. I am in Calif. so having my car towed to your house might be a tad pricey. Besides we have Gavin Newsom and he fixes everything. Thanks for your time.
Great finish and insight into the coding. Also, I liked how Ivan explored the mirror being a potential module awakening issue too just in case since it was known problem. Great study.
I remember when windows had crank handles. If it rained you could just crank them up without running back into the house to get your keys. But of course Ivan, that was before your time.
Those Number are hex numbers (Base 16). Long coding lets you turn on and off different options. Some of those might not be installed, but you'll find out when you play with it. Do record everything though. One possibility mentioned in another comment is that the module was coded wrong which made the module behave erratically (not going to sleep). Definitely play with it, but maybe on a Golf, or other model with modules that are more accessible. We have a 2017 Golf. I read up on it and got myself an ODBCII reader to play with it. And being in IT helps a lot. Love your channel! I learn a lot; it's fascinating what electronics can do with cars.

Cool! I have one of those tiny DM volt meter's too! Love it. OK... I have a 2004 V10 Touareg, 500K miles. Dreaded battery drain problem. Occurred at the same time my outside door lock. button stopped locking the car. I put a amp meter on the battery under the seat (which is easy to flip up the seat). And traced the power usage by pulling fuses and relays. Turned out to be a short in the driver side door handle outside button. It became corroded. So the car thought the button was being pushed all the time. Thus activating all the key-fob radios. 5 amp drain, 24 hours a day. Devours batteries, kills the alternator. I peeled open the button, ripped out the surface mount switch and epoxy filled it. I get no thrill using that button.
Just got my scope, neat little thing. 1 small issue to report that might help folks. I turned it on when i got it and it seemed to work just fine but the batt indicator said low batt. Next day I turned it on, plugged in the cable to charge it and the battery must have been too weak to power the device and it sorta crashed. I could see a (very faint) big battery sign on the screen with a thin red line showing it was low, but there was no response from any buttons, even a long or super long press of the power button. I took out the 4 screws on the back and unplugged the battery and it is now working just fine. I know nothing about scopes, thats why I bought this lil fella, cheap education :)
Awesome diagnosis and fix. A friend of mine talked to an Amish buggy builder and is about ready to get one of those. 😂😂 The state sells the wild horses cheap with a clean bill of health and the entry model buggy is about $3500.00. 🤔
Pico and probably others have a decoder for Can and probably more that may be able to get the address of the module(s) talking on the network. Not a typical DIYer tool but if you know who is who on the network you get the address and the data being sent. The cat man was looking into it.
I don't think knowing the ID of the module that is sending a particular network packet would help in a 1-off diagnosis like this one. After decoding the ID (priority), you would still have to figure out which device uses that ID. It's not like a home computer network, where each device has known MAC and IP addresses that you can look up in the device configuration. I do think that feature could be very useful when diagnosing more complex CAN problems or building / modifying CAN-enabled devices.
@@n124lp The id’s “addresses” are usually not published by the mfg but there is some info online. “OG” has a GM database started that was very detailed but may not be allowed on TH-cam. I found a VW site also. One rule of thumb was that the lower the ID the higher the priority on the can bus.
Good work. Well done. ...on the end, parked in town but still sitting inside, I thought: 'and then there was a seat sensor and due to the driver is still inside the car won't go to sleep again!'. But clearly not. Well done.
Ivan, Thank you for lead on scope. I have been wanting to get one but could not justify the cost of Peco which keeps going higher and higher. This is a great alternative. Thank you!
I went ahead and snagged the scope! It's faster than getting out the laptop, figure the big boy scope can come out when you need to look at things in-depth. Great video!
Another excellent video Ivan! Always learning something from you! I like the small oscilloscope. I've been using the Hscope 402 home made and it works really well, too. Thank you for sharing and I am ready for the next one. Take care.
I would think that 2020 and newer vehicles are almost impossible to fix by us diy'ers especially since it was a chip that was the reason for vehicle shortage which I never understood. Great diagnosis and fix!✌🏻
Plenty of budget scopes out there now - Hantek 1008C - 8 channel USB Automotive scope with signal generator for around $100, OWON HD272S scopemeter (dual channel 70MHz) for around $200 with signal generator, ZOOLARK circuit debugger - dual trace scope you can practically hide in your wallet for around $100. the OWON and Zoolark have the benefit that despite a small onboard display they can work with a laptop. The OWON will even work on the laptop as an oscilloscope / signal generator WHILE you are using it as a Multimeter. The toys for technicians are becoming very, VERY good without breaking the bank.
DIY electrical troubleshooting without factory schematics is getting less viable. Indeed, this was insane level of research for a specialist with all the tools.
wow GREAT diag Ivan, your a parasitic drain detective champ and yes looks like extra tools like a scope+ record keeping otherwise the head might spin around in confusion..That size battery massive, battery reminds me of a diesel i owned when in early 20s was massive, cost a packet to replace too..
Good one Ivan! Nice 2 channel scope also! My first 2 channel scope was a Fluke 98 and at about $3000.00 it was used as often as I could use it. Was not easy to use, but it did have "flight record" which was a BIG help, especially with intermittents and when needed a 2nd digital multimeter.
The replacement module was older with an older software version and it worked. Unless the ecu or other modules were updated and the original door module wasn't there's no reason they shouldn't work together as they were working together before.
That's pretty cool info with the "long code" stuff. I've seen it in my Launch before, but I never really messed with that. Good to know. So, both folding mirror motors are dead? It's kind of a cool lazy man feature to have. it's really not necessary though. But if the mirror is flopping around, they might want to get that fixed. Anyway, another satisfied customer. Nice work Ivan.
Let's pretend that I had a moment of insanity and purchased a lovely Volkswagen like the one featured in this video. As a DIYer, I feel this would be beyond my skill set. So, I would simply go to your website and make an appointment. (From my house to Clarion, Pennsylvania is about 12 hours.) I understand Pennsylvania Furnace is nice this time of year. This buying stuff from Flea-Bay, Ivan? I would probably insist on component-level repair. All of these hexadecimal numbers for the binary digits for coding? Sounds like fun! Of course, I'll never be fortunate enough to own one of these nice cars. Gee, the ol' Marquis has heated mirrors and after 28 years they still work! Great video!
neat little scope. don't mind if I do. plenty of uses for this little guy, even if you have a pico (which I don't as a DIY). if your laptop falls off the car even once while doing a simple LIN scan or relative compression, it's worth it's weight in twonies (yep im canadian). save the pico for ignition/spark/timing analysis or other detail oriented tasks.
To quote what somebody one told me. "The day you stop learning is the day you start to die." Nice work my friend. I was never a fan of the u-scope. I may have to check out the one you used. It would beat breaking out the snap on for issues like this one.

Great diag. Finally I get closer to seeing the difference between Coding and Programming on VAG vehicles. Coding is just a way of disabling or enabling options on modules (depending on trim level and model). It would appear that Programming goes beyond this to stuff like VIN registration,etc?
The reason to put more modules into a car is that customer is forced to go back to the dealer network for diagnosis. You are lucky that you can replace the module. I believe in one of Alfa Romeo models (do not remember which one) Climatronic module can be programmed only once to the car. If fails need new one. That is very common in Europe, but I know is is coming to US also (Cadillac I think).
Wow, lil bitty module going bad!!?? Wow, that's cool too see the scanner can do the long coding and making changes etc. It's good thing you double checked it to be sure if it's that offending module! Nice job of testing and checking it. Awesome video!! Many thumbs up 👍 👌 i wonder if that scanner can make changes of the coding to add features to the vw? Curious to know if it can do it
The long code is the same for all cars it is actually referred to as variant config. Basically if you on a can bus request to read a data identifier e.g A1. A1 on Holdens are the variant configs for the module the Module will respond with what it has in that memory location 2E,7F,5A,4R. Changing 7F to 3E will enable tpms or 2E to AA will enable hsv mode (NOT ACCURATE HEX VALUE FOR HOLDEN JUST EXAMPLE)
Nice diag Ivan! It's crazy how complex modern cars are...one really has to wonder if all that complexity is really worth it though. The old VW in my garage has exactly 10 fuses total and zero modules...so easy and simple anybody can troubleshoot it. How times have changed. And thanks for the recommendation on that scope...was actually looking for a decent inexpensive scope and your recommendation of the Leolov is good enough for me. Hopefully you'll get a few bucks from the sale 😉
Hopefully I never need this little scope, but for $111 I’ll buy it since The Man (Ivan) says it’s pretty good. I only work on my own vehicles, haven’t needed one yet. But it would’ve helped, so what the heck. Thanks Ivan
You seem like an expert at tracing these. I have a problem for you thats similar, 2011 dodge grand caravan crew 3.6 L V6. Please help if you can I’m at my wits end I’ve been looking over this thing for two months

It's not like a home computer network, where each device has known MAC and IP addresses that you can look up in the device configuration.
I do think that feature could be very useful when diagnosing more complex CAN problems or building / modifying CAN-enabled devices.
@@n124lp The id’s “addresses” are usually not published by the mfg but there is some info online. “OG” has a GM database started that was very detailed but may not be allowed on TH-cam. I found a VW site also. One rule of thumb was that the lower the ID the higher the priority on the can bus.
Good work. Well done.
...on the end, parked in town but still sitting inside, I thought: 'and then there was a seat sensor and due to the driver is still inside the car won't go to sleep again!'. But clearly not.
Well done.
Ivan, Thank you for lead on scope. I have been wanting to get one but could not justify the cost of Peco which keeps going higher and higher. This is a great alternative. Thank you!
I went ahead and snagged the scope! It's faster than getting out the laptop, figure the big boy scope can come out when you need to look at things in-depth. Great video!
Nice work again dude, your diaganostic skills are second to none
thanks to you and eric o i have a better understanding of networks and wiring. great diag and repair.
You are geniuses in diagnosis ❤
Another excellent video Ivan! Always learning something from you! I like the small oscilloscope. I've been using the Hscope 402 home made and it works really well, too. Thank you for sharing and I am ready for the next one. Take care.
I would think that 2020 and newer vehicles are almost impossible to fix by us diy'ers especially since it was a chip that was the reason for vehicle shortage which I never understood. Great diagnosis and fix!✌🏻
Plenty of budget scopes out there now - Hantek 1008C - 8 channel USB Automotive scope with signal generator for around $100, OWON HD272S scopemeter (dual channel 70MHz) for around $200 with signal generator, ZOOLARK circuit debugger - dual trace scope you can practically hide in your wallet for around $100. the OWON and Zoolark have the benefit that despite a small onboard display they can work with a laptop. The OWON will even work on the laptop as an oscilloscope / signal generator WHILE you are using it as a Multimeter. The toys for technicians are becoming very, VERY good without breaking the bank.
Ваня как всегда молодец!!!! Нравиться твой канал ! Спасибо большое
DIY electrical troubleshooting without factory schematics is getting less viable. Indeed, this was insane level of research for a specialist with all the tools.
Great diagnosis Ivan. I love your methodical approach to finding the issue. You must have a long list of repeat customers.
wow GREAT diag Ivan, your a parasitic drain detective champ and yes looks like extra tools like a scope+ record keeping otherwise the head might spin around in confusion..That size battery massive, battery reminds me of a diesel i owned when in early 20s was massive, cost a packet to replace too..
Love the parasitic draw videos. Very cool haw you hunt them down. I'm liking that little scope too!
Good one Ivan! Nice 2 channel scope also! My first 2 channel scope was a Fluke 98 and at about $3000.00 it was used as often as I could use it. Was not easy to use, but it did have "flight record" which was a BIG help, especially with intermittents and when needed a 2nd digital multimeter.
Wonder if you could update the module with your other scanner through the internet. Maybe it wasn’t the module but a update
The replacement module was older with an older software version and it worked. Unless the ecu or other modules were updated and the original door module wasn't there's no reason they shouldn't work together as they were working together before.
That's pretty cool info with the "long code" stuff. I've seen it in my Launch before, but I never really messed with that. Good to know. So, both folding mirror motors are dead? It's kind of a cool lazy man feature to have. it's really not necessary though. But if the mirror is flopping around, they might want to get that fixed.
Anyway, another satisfied customer. Nice work Ivan.
brilliant diagnosis
Great skills.... definitely know what your doing....
Let's pretend that I had a moment of insanity and purchased a lovely Volkswagen like the one featured in this video. As a DIYer, I feel this would be beyond my skill set. So, I would simply go to your website and make an appointment. (From my house to Clarion, Pennsylvania is about 12 hours.) I understand Pennsylvania Furnace is nice this time of year. This buying stuff from Flea-Bay, Ivan? I would probably insist on component-level repair. All of these hexadecimal numbers for the binary digits for coding? Sounds like fun! Of course, I'll never be fortunate enough to own one of these nice cars. Gee, the ol' Marquis has heated mirrors and after 28 years they still work! Great video!
I bought a scope been looking for one I can justifie for DIY thanks Ivan
neat little scope. don't mind if I do. plenty of uses for this little guy, even if you have a pico (which I don't as a DIY). if your laptop falls off the car even once while doing a simple LIN scan or relative compression, it's worth it's weight in twonies (yep im canadian). save the pico for ignition/spark/timing analysis or other detail oriented tasks.
I have learned so much from your vids , thanks
Thank you Ivan!
These tips and tricks save hours of "learning the hard way".
Your videos are like hours of experience, in short, absorbable chapters!
What a complete ball ache. Top work!
Nice and correct call once again as usual 😊
To quote what somebody one told me. "The day you stop learning is the day you start to die." Nice work my friend. I was never a fan of the u-scope. I may have to check out the one you used. It would beat breaking out the snap on for issues like this one.
@@Runco990 Which model Owon? I started with an OWON DSO 7 years ago, and then upgraded to one with a battery pack. Then got a used MODIS 4 channel and then a Verus 4 channel :)
@@Runco990 Looks neat! I like the built-in multimeter :)
Thanks Ivan, I just ordered the 2 ch Oscope using the 20% off Code, this will be a nice addition my troubleshooting bag. Love your videos, keep them coming...
What code did you use I can’t get it to work thanks
@@ericvandenk5991 they said that they are low on stock thanks to this video 😂
Send them an email at help@leolovus.com and ask to hold a unit for you with the big discount 🙂👍
Hi Ivan
You are super prof, you can reed schema, and understand howe things works togheter,
You have verry
high education
Car mecknik dont have that they just can switch parts they see on computer this is out of order and put new things in the car. They dont anderstand
1 2 3 of no 1 is wrong they follow to no 2 and 3
This is the problem with mecaniks
When you works with newer cars you must use the brain and have education
You are outstanding one of the best 👌
Great diag. Finally I get closer to seeing the difference between Coding and Programming on VAG vehicles. Coding is just a way of disabling or enabling options on modules (depending on trim level and model). It would appear that Programming goes beyond this to stuff like VIN registration,etc?
The reason to put more modules into a car is that customer is forced to go back to the dealer network for diagnosis. You are lucky that you can replace the module. I believe in one of Alfa Romeo models (do not remember which one) Climatronic module can be programmed only once to the car. If fails need new one. That is very common in Europe, but I know is is coming to US also (Cadillac I think).
Thanks for the video,
Dude, you’re a bulldog! Excellent job.
Planned obsolescence for sure. Not only electronics but major important mechanical components it’s a big problem on new/newer vehicles
Wow, lil bitty module going bad!!?? Wow, that's cool too see the scanner can do the long coding and making changes etc. It's good thing you double checked it to be sure if it's that offending module! Nice job of testing and checking it. Awesome video!! Many thumbs up 👍 👌 i wonder if that scanner can make changes of the coding to add features to the vw? Curious to know if it can do it
Awesome diag and video, Ivan! Getting kinda "scary" when your only viable source for replacement parts is ebay.
The long code is the same for all cars it is actually referred to as variant config. Basically if you on a can bus request to read a data identifier e.g A1. A1 on Holdens are the variant configs for the module the Module will respond with what it has in that memory location 2E,7F,5A,4R. Changing 7F to 3E will enable tpms or 2E to AA will enable hsv mode (NOT ACCURATE HEX VALUE FOR HOLDEN JUST EXAMPLE)
Pretty rare for a VW not to have heated mirrors. My base model 2019 Jetta has them and pretty much every VW we've had has had them.
If the code was ON that would have said no heated mirrors. Code OFF said YES they are heated
@@jima7925 well ok. Just saying it's rare for a VW not to have heated mirrors.
my base model 96 Mercury has heated mirrors...no power locks or windows or cruise control, but heated mirrors. So weird haha
Nice diag Ivan! It's crazy how complex modern cars are...one really has to wonder if all that complexity is really worth it though. The old VW in my garage has exactly 10 fuses total and zero modules...so easy and simple anybody can troubleshoot it. How times have changed.
And thanks for the recommendation on that scope...was actually looking for a decent inexpensive scope and your recommendation of the Leolov is good enough for me. Hopefully you'll get a few bucks from the sale 😉
I paid $82 delivered for that scope a few months ago from aliexpress, it did take 3 weeks to arrive though.
Thanks for you vidéo Ivan 👍
Ivan, just fyi 5E in hexadecimal (base16) converts to 01011110 in binary in that module long code
Hopefully I never need this little scope, but for $111 I’ll buy it since The Man (Ivan) says it’s pretty good. I only work on my own vehicles, haven’t needed one yet. But it would’ve helped, so what the heck. Thanks Ivan
darn it, I had to buy one to go with my Hantek 1008b and DSP5202p
It would be fun to see a quick disassembly of these bad modules. Even if we can't see smoking guns, a quick tour inside would be interesting.
Great Job 👍.
That's crazy a door module caused this draw.
Hah that was the reason for the INSANE title 😅
Great work as always Ivan! I bet the customer was relieved to have it fixed 👍
You seem like an expert at tracing these. I have a problem for you thats similar, 2011 dodge grand caravan crew 3.6 L V6. Please help if you can I’m at my wits end I’ve been looking over this thing for two months
The oscilloscope also has a waveform generator, which could be very useful, if it works well. I did not watch any reviews that tested this feature.
Good job Ivan.
Challenging one always learn from your videos thanks
Great work Ivan.
I am in Central New Jersey. There isn't a shop anywhere near here where this diagnosis and repair could even be made.
would be interesting to open up the controller
where did you connect the o-scope to monitor network signal? thanks awesome video
Thanks, I was cutting wires. Now I know to pull a fuse
Great video, thanks for the coupon on the scope, just what I was looking for.👍
The modules have small micro switches which usually go bad due to foreign matter and/or failure which causes battery drain
Great diag and fix👍
I keep a bag of those trim clips handy because at least one breaks every time those panels come off 😕
Great Job as always!
I think you should complement VW for at least make its modules go to sleep quickly, I know you don't like Euro stuff Ivan, but I remember videos of you waiting quite a bit for modules go to sleep on American cars...😊
I don't mind Euro cars...they are just a little different than most other cars here in the states :)
@@PineHollowAutoDiagnostics You did say Fords were some of the worst.
Any crusties on that old modul?
