Just get fault code 404 - Page not found for the topdon EU link
I have a autel maxisys elit. Is The topdon phoenix max a good upgrade compared to The autel? Best regards from sweden
Great video. I also get an error on US link
@@hamberg91it's similar, both very good tools
Are Volkswagen cars really that unreliable or is it just media bias?
Great to see someone doesn’t just go “oh, it’s a gateway module” and throw one in. It’s diagnosed thoroughly and properly. Great work.
No one wants to pay us to thoroughly and properly diagnose…therefore most who can have left the field
Especially in this case it easy to confirm the wiring.
@@andrewcimochowskii guess that really depends on the customer.
As an old bloke I appreciate your contortionist efforts to film under the dash for us. Thanks Dan.
you think you're old, I took my test in a series E Morris
@@mrgrumpy5116that's nothing. According to my kid, took mine on a T-Rex! 🤪
With you on that aussie.😅
Another Aussie agrees with you. After working on my car, even my aches have aches.
A comment like this makes it worth while. Thanks😁👍
Who doesn’t love a new diagnose Dan video! Very interesting, learn something new every day. Thanks Dan 👍😃
DD is a bossss!!
I learned never to buy a German car.
Thanks Simon!
Man I was expecting a bad ground, no parts required repair 😄
Great diagnosis Dan! Having the donor module on hand was very helpful! 🙂
I'll leave the "No parts required" videos up to you🤣 Having a donor module was helpful Indeed. The customer agreed to installing a new one and i programmed that using Odis👍
I would like to greet Dan and thank him for his video from 2017 that solved my problem of difficult first engine start on 2.0 TDI passat B8,2014 year. According to his diagnosis, which he did at the time on golf VII, I replaced the VVT valve in an authorized vw repair shop (housing with solenoid and executive valve) and now the engine starts without problems. Even vw experts could not guarantee that the repair would work, but it worked. Many thanks for your great expertise. Greetings from Bosnia.
Thats great to hear!
Another fantastic video. It's clear why other shops send their problems to you - your outstanding diagnostic skills. Appreciate you bringing us along. Looking forward to the next video.
Thanks Frank 👍
A Volkswagen that cranks itself. No wonder, it's basically Herbie's great-great-grandson 😅
Great video again Dan! Good stuff
🤣🤣🤣
The in depth knowledge of electronics that Dan had it's amazing. This the guy that when everybody else tried and did not succeeded, is the one that will. My 2 cents. Thank you for sharing Dan.
A comment like this makes it worth while. Thanks for taking the time to watch my videos and leave a comment
Another really useful video, thanks Dan. I’ve built up an extensive collection of your videos in my “Saved” list, so if I get a problem, I simply go to this folder and search for your relevant video. It’s already becoming a comprehensive and invaluable library.
😎
Ha ha thats great!
I’m sure you aren’t the only person in the world with such a confident and thorough knowledge of the black magic of modern CANBUS systems, but you are the only one I know of and it’s very reassuring that it isn’t actually magic or “weird”. It’s all stuff that can be symptomatic and for the right person possessing the proper knowledge and experience, it’s just following the chain down to the problem, like any other problem on a car.
@DiagnoseDan I had a similar issue with a Skoda Octavia of the same age. Came into our shop with an oil leak, that once fixed by my colleague, the engine was steam cleaned off by him with it running. He drove it back in the shop saying the dash was lit up like a Christmas tree with warning lights. After switching off, it would not restart. There was no comms either with a scan tool. I half expected the fault to be under the bonnet from the steam cleaning, but (long story short) testing with scope found the bus shorted to ground, which I located to the gateway. I removed it and water ran out of it! Turns out, a poorly fitted replacement windscreen meant the steam cleaner pushed water through a gap in the windscreen sealant and down the bulkhead sound insulation straight into the top of the GW module! So we had to buy the customer a new GW module and inform them their windscreen needed resealing. Bad luck for us, but a lesson learned.
You wouldn't believe the amount of faults i have diagnosed because of poorly installed aftermarket windshields!
The reason Dan is so successful is that he takes the time to DIAGNOSE the ISSUE and not just thumb suck to make a quick buck. if dealers actuality took the time to diagnose a vehicle i am sure they would find the faults, but people are lazy. Keep it Up Dan
Thanks for watching
On a cold wet January morning in the UK and being a retired Electrical Engineer I enjoyed the video. Keep em coming. 👌
Brilliant again Dan, can’t understand why people use other garages rather than going to the man who diagnose,s and does it properly, hi from Ireland
😁🇮🇪👋
I guessed right! Would be interesting to look at the wiring diagrams to see if a voltage spike (from damaged alternator) could scramble the gateway.
It could, but the gateway is not 12V. It's probably 3V3 or 5V. So a 50C voltage regulator is probably all it needs.
@@giusdbgTrue, the gateway is probably toast. And the electronic did have some voltage spikes and then faiiled. If the regulator failed, it would have burned the print.
Thanks for your interesting comment. I didn't think about that since the alternator was already replaced
@@Diagnosedan You nailed it right away, anyway! (that's why I'm here- to learn) I was just trying to think how the complaint came to be: what changed? accident; what happened in that accident? alternator was replaced. (you checked for water damage in the central gateway*; water damage messes up the electrical components; voltage spikes, from, perhaps, a compromised alternator, could also damage the electrical components) * I have an MB W211 car and I follow various issues with these cars and have discovered that water incursion, from poorly sealed windshields, result in failed/failing central gateways: fortunately I haven't had this issue.
Thanks for the great content Dan! Those shops must be thankful to have such an intelligent guy close by who can help in a pinch!
Thanks for watching 😊
You are the man,diagnose Dan,it’s always great to see you work on the difficult problems,thanks
Thanks for the great comment
Brilliant. Not only the process but the clarity of explaination (especially as English is not your first language). ❤
Thank you
car tried to crank itself.... does that make this episode the Halloween special? 😂😂😂
😂😂
@@arga1966 I had a Lexus that had a strange problem before. After I turned and removed the key, the engine would continue to run. The engine continued to run for another 2 or 3 minutes and then turned itself off. You would probably think that the key cylinder was bad and needed replacing. That was my first thought as well. But the problem continued after the key cylinder was replaced. Turned out that it was the car's ECU that was faulty. The replacement part was around $2800. Fortunately, the car was still under factory warranty at the time, so I didn't have to pay. It's still running great today, after almost 230,000 miles.
@@S_Paoli 😱thanks God it was under warranty mate.
That is expensive 😞
Exactly 😂
🤣🤣
Thanks so much for this video! I have my Vento Variant (Golf variant in my country), same as the one in the video with the same issue after a front crash. The mechanic was going crazy trying to figure out a solution. I will suggest this.
Dan, I just wanted to say thank you for everything you teached me and others. Thank you.
Thats great to hear!
I guessed right from the topography which is just like a wiring diagram.
Where I guessed, you proved.
That is what the customer wants. 💯
Great thinking 😁👍
So nice to see a real expert who is using deeper tools to diagnose thing rather than just plugging a scanner and saying “don’t know” when it’s not coming back with nothing.
New subscriber from this video.
Thanks for subscribing!
Fantastic Dan, your methodical problem solving is something to behold
Thank you!
Great one as usual. Common sense is key to a successful diagnosis 👍👍👍
Exactly!
Was so scary but had an idea of where to start. Thanks Mr Dan. I wasn't expecting it so short😂. That was so cool. Im helping yu to diagnose from southern Africa 😂😂😂
Yes short diag this time😊
You're a legend Dan! Your knowledge never ceases to impress! Tip of the cap to ya.
Tip of the cap, i had to look that up😂 thank you Jacob 😁👍
This has become my favorite computer repair channel.
🤣🤣
Love this!! My 15 Sportwagen TDI went in for a random check engine light and it ended up having a short in the wiring harness, needing a new ECM, and some other items were replaced under an aftermarket warranty and the TDI warranty. I wonder if the issue was the wiring harness/engine loom all along. Luckily, I didn’t have to cover all the parts and labor.
your videos have helped me with diagnosing vehicle problems immensely. Thanks again Dan!
Hi Mike, thats great to hear. I hope one day we can meet in person
@@Diagnosedan I'm re retiring sometime in the near future and I got my passport! I'll let ya know!
I suggest that the channel be called professor dan, I enjoy watching how you solve complicated electrical problems on vehicles and at the same time explain to us in a simple way how to solve the problem. Thanks for the shared knowledge and expertise.
Its a pleasure max
Thank you very much for such an educative video
I always make sure I watch at least five of your videos before I go to bed and it’s really worth it to me as an undergraduate student
Ha ha dont you get nightmares😂
@@Diagnosedan haha just as you’ve said so 😂😂😂😂😂😂
Hi Dan. Just stumbled on your video clips and had to subscribe. Your enthusiasm, excellent communication skills in explaining, diagnosing and repairing a faulty unit is faultless. Car dealerships should take time to learn a tips from watching your channel. Keep up the good work on your channel 😊
Great job as always. How understandable diagnostic could be when someone explain it on this way. Bravo 👏
Keep it simple!😁👍
Just watched Jake doing the same thing, awesome Dan you fixed it again!!
Yes what are the chances!
Dan's most powerful weapon, mechatronics!!!! Fascinating how it diagnoses, tests, verifies, communication signals between modules. Supply voltages of the modules.......fabulous! Congratulations Dan! Thanks for the feeling of sharing your achievements with different cases of car defects. God bless you! Good health!
That is not what mechatronics is
Thanks for your great comment it's really appreciated
Your videos are so well presented and clear thank you 😎
you are the best greetings from Germany💯
First decent RUclips content today, thankfully I subscribed 😀
Thanks for subscribing and i hope to see you more often Steve👍
Good job again,Dan👏
Right diagnose it is 99% successful repair.👋
Thanks for watching
VERY impressed with your communication skills as well as your step-by-step logic in diagnosing. 😃
Thank you
Well done Dan, the way you present the problem, it looks easy, but actually this is one of the more complicated problems and few of the garages, even importer garages, will solve the problem in a short time, they have the advantage of having a stock of spare parts. By the way, I purchased TOPDON a long time ago, an excellent scanner with lifetime support
I can imagine that some technicians are lost if they can't read codes.
Is there a car you can't or couldn't fix ? I watch your materials & also learn some things. Good work !
Thanks for watching!
Good diagnosis and checking the basics, I know someone who ordered and installed a new ECU only to find a blown fuse.
Thats sucks😬
Great case study Dan, thanks for the in-depth footage and a breakdown of your own thoughts here. Hopefully if I get a similar fault at the workshop I'll remember this video
Thank you very much
Thank you Dan for your excellent diagnostic videos. I learn from each one you do.
Thats great to hear
well done dan i play around with my vw golf mk6 i got plenty of spare parts line around so if my car breaks down i can change out parts to see if i can fix it my slef. so i got hold of a second hand unit out of second hand car swap it out to see what would happen and the car started up with may be one or to light on the dash so if i go throw the coding on my gateway module and have to change a digit of two it works fine but i would always take a back up coding of the module just in case. But it really not something to play around with. Thanks dan for sharing
Of course you can only back up the coding if you can read the old unit😁 But dont worry there are other ways to code the module without the backup
You are so lucky with a LHD vehicle. On a RHD car it is located above and behind (looking from inside) the onboard powers supply module (09) and the way to get at it is by removing the windscreen scuttle, wiper motor and sealed access cover. As you can imagine water damage is quite common!
I like that pragmatic approach to problen solving and never get tired of your videoes Dan. There are a real treat here on you tube 😁👍
😁😁😁😁😁
Massive respect Dan from the UK 🇬🇧 and Ireland 🇮🇪
Thank you
Ik heb met veel aandacht jouw verhaal gevolgd.
Het was even heel goed opletten, maar ik heb het begrepen.
Mijn dank is dan ook weer groot omdat je de moeite heb genomen om er een video aan te wagen.
I have followed your story with great attention.
It took a while to pay close attention, but I understood.
Thank you again for taking the time to make a video about it.
Dat is geweldig om te horen, dit soort berichten zijn precies de reden dat ik deze videos maak!
Dan, Your title says the best: brain dead V.W, and the same is also true for anyone buying a V.W 😂
Putting jokes aside, you are the KING of car diagnosis !
Thank you very much
Excellent job Dan an easy fix shame they spent out on a new alternator when it was the module. Keep the videos coming 🇬🇧👍👍👍👍👍
Thanks for watching Michael
First time I coment on your videos , and all I can said , is you are the best mechanic , not only cuz you fix the problems. But cuz you are a good person, you care about customers. I love German cars, i have a few, but have a bad experience whit it, and the worst. Is that I'm a mechanic on American brands, and I cat solve mayor problems whit my own cars, thanks for share all of your experience
Thanks for taking the time to leave a comment its really appreciated.
Fantastic Diagnosis Dan. I think! If a friend brought me his car with all those symptoms, I would have curled up in a corner and started whimpering. 😩😩😩. 😂
🤣🤣
Happy to watch your new and very interesting videos. Thanks Dan❤❤❤
Great!😁👍
You are better than any school!!!
Hartelijk bedankt.
Graag gedaan 😁👍
My working VAG does the same, if start stop is on, and lets say I stall it, it will restart by itself. Have done that from new.
I had the same age and the same 1.6tdi golf, and in winter when it used glow plugs i just held the brake and turned quickly to start the position and the car would crank and start automatically after the glow was done.
This one doesn't 👇

I've said it before and I'll say it again, THE best diagnostic channel on RUclips.
The best for YOU! There are other channels that have the same (or better) level of expertise than Dan.
@@desertstar223 which ones?
@@jeffreybell5454 Pine Hollow Auto Diagnostics, South Main Auto, Ford Tech Makuloco. You want more?
Thank you
@@desertstar223yes of course but you dont have to tell me that😂😂😂😂
Just started watching, paused at 1:04
The situation you've described happend a couple of years ago to my grandfather's car.
This was a Ford Mondeo, one time during a storm, a tree fell on top of the car.
It went into the dealer's shop, they "fixed" it, then it started to do weird things, been back to the shops like 6 times and they couldnt replicate or find the problem.
It ended with the car starting itself and driving down a hill without anyone inside, landing on top of some metal poles, totaled, luckily nobody was hurt.
(My grandfather had seen his car starting itself(lights turning on) and driving off through the kitchen window when he was eating breakfast)
Turns out it was the windshield, the tree that fell onto the car busted among other things the windshield, they replaced the windshield but apparently theres some circuitry or sensors inside or connected onto the windshield and they were supposed to calibrate or reset a module or computer, which they forgot or didnt know, these systems were brand new at that time.
I don't know the exact details but that's what my grandfather told me happend and what caused it to happen.
Anyway, going to watch the video now, I wonder if it's a similar problem.
Edit: Well, it wasn't the same, stil interesting though. Thank you Dan! Informative and entertaining.
Thanks for sharing that interesting story!
As always Dan, thank you for sharing, you make it look so easy but when you are an expert like your good self well enough said. 👍👍
Thanks for the great comment, and sorry for the late response 😊
No worries Dan, I know that you are busy. 👍
Great video again Danny. Must admit I thought it was going to be water ingress issue with all that debris along the scuttle and drains!!
Me too!
Your spot on with your diagnosis techniques.
Love your videos.
Please put out more.
Thank you
from what I've seen , some mechanics or customers trying to fix it themselves, during diagnosis process or installation , they grounded a wire related to the modules by mistake and fried them (since there's no diode in between to prevent this) . As for example not disconnecting negative terminal during the alternator replacement.
Yes! Once I hear that Dan has posted a video that's me a happy man!
Thank you 😊
Love seeing you have new videos.. Thank you!! 🇺🇸
Thanks for your comment
Thank you for this very informative video. A very difficult problem made to look achievable.
Awesome diagnosis again Dan, epic 🎉
Thanks!
You fixed it again, Dan! I really appreciate your professional standards. Once again, you have proved that an oscilloscope is a great tool to have in a car repair shop. The coding of the gateway will be a challenge if nobody saved it before but it is not impossible. Great job and thanks for sharing your knowledge!
Many vehicle manufacturers today have a database with the vehicle options and configurations today, but they may request that it's programmed by a dealer. It's a grey zone of repairability there.
To me a gateway module makes sense primarily to protect the vehicle from issues that could impact the CAN bus traffic from the OBD port.
Some cars are exposing their main CAN bus on the OBD port and that could cause some headaches if you plug in the wrong accessory on the OBD port.
@@ehsnilsSome VAG vehicles have a sticker in the trunk with the complete options. Some have it in the owner's manual.
@@repairingmaster I see, I had some experience with Volvo trucks where the amount of options is much larger. I'd hate to read them from a sticker.
@@repairingmasterYes, you’re right, but that are options from the factory. If one adds afterwards for example a towing hitch the module for commanding the trailer lights has to be programmed into the gateway as an other audio system that will be replacing the old one. That’s the VAG way.
@@DrDre-ir4gu Correct. I once had a challenge with a new beetle that reported troubles with the sliding roof mechanism but was lacking one. Turned out that the entire piece was replaced with one piece rooftop after a vehicle rollover during a crash.
Very good job Dan. Keep up the good work! I enjoy your videos very much but maybe would make sense to warn people to don't try ECU swapping for testing on the newer generation cars because problems can appear. For example on BMW where the BDC is the gateway too if you swap it for testing with a module from another car it will trigger component protection on headunit.
Great point👍
very enjoyable Dan and another great diagnose. cheers Dave NZ
I always learn something from your videos. Thank you 🙏
Thats great to hear
WoW Man you're AWESOME👍🏻
DiagnoseDan Fixed it Again😎
Stay Safe BRO👍🏻
Thank you
I had a similar issue a year ago with an Audi a7. Car went to a few shops and no one still able to fix it. I got a pathways now because of you’re video to see If it’s same issue. But I was the same issue. But if I had the hazardz turned on and driver door open. It would communicate but still no start
On top we are a bodyshop and the car had rear end damage
I think you should investigate what wakes up the network. When you put the hazards on the networks wake up. On some cars we would put the hazards on while programming to make sure the network doesn't go to sleep.
Interesting! 😮
Good to see you again Dan. Thanks for these great videos. Stay Safe.
Thanks!
I would of been Soo confused, sad thing is I used to be a VW tech but never ran into this but makes so much sense. Great video
Its not uncommon for these modules to fail

Great and short path to figure out the roots of the problem as usual great Job!
Thank you
Nicely done Dan 👍🏻
Thanks!
DAN, brother of course enjoyed the video and bravo to ur thought process and approach always learning from the best thanku for taking the time to do this. cheeeers
Thats great to hear
When Dan uploads a video, I first click like, then watch 😊
🤣🤣👍👍
Excellent work Dan 👍
Thank you
Good to confirm before replacing. Would always have suspected the gateway. Like you was expecting it to be water damaged. Have recently seen 2 Golf MK6's with water damaged CAN gateways and parking sensor modules.
Water and electronics definitely don't mix.
Thanks for watching
Great find this one Dan 👍
Hello Dan ,great video ,as always very detailed for us on how to diagnose ,tank Dan ,you fixed again 😀 👍
😁👍
Como siempre el más chingon 💪 dan great job
Thank you
Yikes not only fuel and electrical but no we have to worry about networks to make the car run.
Thank you for another fun video Dan
Thanks for watching Andy
Dan, you’re a car scientist.👏🏻👏🏻👏🏻👏🏻

Great strategic diagnosis. As always Dan fix it again!
Thank you very much
Good work. Lucky to have a donor car to check. Always hated going though all the checks and it tells you to install a known part. Never easy to find unless buy a new part.
Thanks for your comment
Another cool video Dan love your thought process.
Thanks
Love watching your videos! Great work as always.
Thanks!!
This video was very useful for me ,, thanks Dan for such good explanation
Thats great to hear, glad you liked the video
Hi Dan, I love your videos and have been a subscriber for a while now. You never cease to amaze me with your skills. I would like to fix an issue with my car in the uk but wondered if I would need an oscilloscope to fix the issue. Vauxhall (Opel) Zafira tourer 1.4 turbo 2017 model. I had a retrofitted CarPlay system (NavInc) fitted by the dealer but they could never get the touchscreen of the car to work with the navinc system. Any ideas?
No Sir i think you need to ask this question to someone who is specialized in retrofitting audio systems
you made quick work of that one. I was expecting you to find a ground problem related to the front end work...
Unrelated this time😉
As usual very educative thanks Dan!
Thanks for this informative video. I know these videos take time to make, and some of them take a lot of time to make.
Yes it takes some time but reading the comments make it all worth it.
A lovely early MGB in Iris Blue. No CAN bus problems there :-)
Certainly not😂
