Haha - watched Dan one night, Jake the next for the same show!? Awesome

Dude that was awesome! You just out-NPRed Diagnose Dan! 🤣👌 I wonder where that oil leak is coming from... If left unchecked it will definitely throw the belt and blow the engine LOL

Diagnose jake fixed it again 😂😂, but i agree diagnosedan is an awesome and smart fellow.. great video thanks for sharing..

Yup..diagnose dan dude should be amazed aand happy..its the best way to share info and help others.cheers

Diagnose Jake fixed it again 🤣🤣👍👍

DiagnoseDan, Ivan, and you all rock! Pretty sure DiagnoseDan doesn’t solder, so you have another tool in your belt! Love the shout out o Dan. Another great vid.

DD TSB 💪🏻❤💪🏻

Lucky for both you and Dan your cars are left hand drive! The gateway on right hand drive cars req removal of the wiper frame to access it behind a cover accessed from below the windscreen. It sits on to of the pedal box, almost impossible to access from inside the car. May help others looking for the gateway on RHD Golf and Skoda Superb around 2012 ish.

Diagnose Dan is awesome , but ghis time The man Jake fixed it , good job man , thanks fir sharing your videis and testing procedures

Nice diag as always, cool to see the gateway coming back to life with some heat

I love Diagnose Dan also! Love this video and your teaching.

How does this dude not have 100k subs yet. Valuable information

Diagnose Dan fixed it again! He is a smart dude

I really enjoyed this one! Thanks for the component descriptions! And yeah Dan is awesome!

It does looks familiar, Now let's fix it , Together! 😂👍

One aspect I like with some of these scan tools now is the topology scan, where it scans all the modules and lets you know which ones are working or have codes in them.

I saw Dan's video and I knew this would be exactly the same. Ivan would be proud of your NPR repair. I'm sure that module would probably be fine but as a professional, you can't warranty it so a new gateway module is the only way.

5:45 Those look like inductors or common mode chokes but I could be wrong. I believe the can bus lines are bi-directional so they wouldn't be opto-isolators because opto-isolators normally aren't bi-directional. You would use a common mode choke to prevent common mode noise from getting to the can bus transceiver. It basically cleans up the noise before the signal gets further cleaned by the bus transceiver.

I did see Dan's video, he didn't take it as far as you did Jake. And even though it needs replacing for warranty. You took it where few techs in your field are willing or able to go my friend. Great Job. 👍

Great job Diagnose Jake!

Great diagnostic, Jake! Reflowing solder joints can bring modules back to life, but it's a gamble - good decision on the replacement of the gateway (if it fails on the road, it's dead in the water). You and Dan got the same fault, almost simultaneously - what are the odds :-)

What’s going on is referred to as latent cold solder joint failures. Was major item we used to look and test for when manufacturing populated circuit boards. (Not for automotive industry) If the automated equipment heat and flux settings on a pick and place system we’re wrong during assembly, this can happen. Testing included repeated testing during a series multiple extreme heat and cold cycles. This would expose bad solder jobs and require a “controlled” reflow process and retesting.

Ha yeah … Diag Dan & Diag Jake are two great technicians and coaches . Gotta love their cool sounding accents too !! 👍🏼🔧

As RainmanRaysRepairs says, things (carproblems) seems to come in waves. Not the first time DD and Ray tackle the same problem at the same time, it's your turn now as it seems 😄

Awesome....

TOP MAN IS OUR DAN .

You got it running with a quick fix but like you said it may only be temporary. Good one Jake!

I like these videos very useful I saw Dan video before your u guys both do fantastic explanation

The reflow reminds me of all the xbox360's with the 'Red Ring of Death' fixes, reflowing the boards, they usually failed again though, so yeah, gateway board should be a recommended change.👍🙂

Beautiful diagnostic brother keep it up

I’ll keep a watch on sale for Black Friday and they can thank you and the marketing department that sent you that. Seeing it in your videos helped me make a choice for sure.

Hello. New to the channel. I watch all the heavy hitters in the diagnostic world. I can see you have my same passion.

Nice, just watched DDs video 😆 must be clock in them to break 😅

👍You and Dan are the man!

Nice video and easy diag after watching Dan. Let’s fix it together. 😂😂

deja vu hey dan have you dan something with your hair

There is no Optoisolator on this board, the components you are showing in 5:53 are 'Ferrite Chip Common-mode Filter' (In most cases dual 51µH Coil). Components are used for CAN-BUS Filtering.

Saw Dan's video too, must have been the same sunspot that took them both out. I was hoping you'd try and fix it, at least check the voltage regulators on the board but reflowing worked! For now. And those are isolators, but not opto-isolators. The opto-isolators wouldn't be wire wound, they are LED based, hence the opto part, but you know that. Those are more like magnetic / inductor type isolators, like used in Ethernet jacks and other com equipment. Which makes sense, it is com signals after all.

Another good one, reflow-a go-go, I'm a fan of reflow using leaded solder, as modern leadfree is not as reliable. The aerospace and avionics industry use leaded solder for safety, I guess the auto industry does not that reliability!

As always , great video .

I bet it comes down to Powers and Ground on a deeper level. That gateway uses a voltage regulator that's probably fried. If curious, check pin 5 (far right) of the V4276 chip for voltage around 5vdc. Invput voltage of 12 should be on pin 1.

Yep saw Dan's video as well.😂😂

Good work

that 5 pin chip to the right is a voltage regulator total failure of a module it more likely to be something common to the whole operation of the device so i would go with checking that chips outputs

🤣🤣🤣 what are the odds of that watch a video and then a few days later get a car with the same fault . or perhaps as you stated it’s a common issue with the vw 😱😱😱😱 . over the years i have done that reflow a few times on modules and xbox’s but like you I always suggest they get a new module . however a buddy of mine i did it to his gem module about 3 yers ago he said yeh yeh i will get one but its still rolling with the reflowed item every time i talk to him i ask you got that new module yet 🤣🤣🤣

👍Greetings from NL.

An interesting coincidence! Does the TOPDON scanner have a full-fledged browser built in?

Those are not optocouplers, they're common mode chokes. They filter EMI but are otherwise a low resistance connection for the signal. The CANbus transcievers are likely integrated in the main microcontroller.

Here in Germany we have a word for VW not Volkswagen we say Völlig Wertlos translated into English totally worthless. But in German the first letters writ better of course. I saw Dan yesterday too, need to make an appointment with him soon. Got a missfire and can't find the problem it's roughly a 500km ride. But Dan is pretty busy.

You fixed again

After year 2000, there was a change to lead free solder, this resulted in electronics failure due to poor bonding to component pins that didn't have the correct plating. Perhaps the gateway has this issue, if the part number has been superceded, likely the problem has been resolved, just a thought based on experience.

I guess it's gateway season!!

Back to back cool video

Those gray components are just inductors, not oscillators. They are used for noise decoupling.

Excellent video 👍

Good job on heating up the module, to prove it is bad.

It was the gateway module

I'd take a bet on it being Lead free solder that caused it.

Don't forget Check Engine Chuck too!

😂 Quite the coincidence

Jake fixed it again 😊

Funny thing I saw that one yesterday from dan

Interesting, My scanner has the FCA gateway subscription. I c also have the bypass pigtail that you can unplug gateway module, plug in pigtail and bypass module entirely. Awesome for this kind of diagnosis. Just a thought. Please note that there are 2 pigtails I am aware of. But you can unplug module, plug in, and then just plug in scanner to pigtail. Its the 12-8 connector (12 in 1, 8 in the other)

good job 👌👍

👍

"Let's fix it, two getter!"

Lol,thats cool

Cold solder joints

VW is just like a Ford!

I funny I work only on European cars and VW is one of the most common one I work on and I have yet to replace one I guess I’m lucky but good to know if I get no comm with the scan tool and no start.

You and Dan got the same fault😃😃😃

👍👍

Therminal chip reset....

Grasias

pin 1 on eprom had slight grey shading as if poor connection?????

Something a little off topic. you mentioned Good Friday sale for TopDon. My Autel subscription is up in 3 days. It is old and it does not have the topology. Just curious if Topdon has J2534 device with their tool. I was curious what is your go to J2534 device you use the most. Thanks for the time you take to do these videos.

nice how do you video sceen on tool when making videos

I wrote the link to this video in the comment section of Dan's video also stating that you mentioned Dan and had the same fault. Unfortunately he deleted my comment right after a minute 😞

It is in a great place cold air at summer hot in the winter what can go wrong

I would like to see you in Europe working with European cars.

Great vid! So how do you 'reflow' a pcb? Does that involve hot air or a solder gun? I have an annoying dot matrix LCD display on a on old 01 Mercedes that ONLY works when warmed up and I cannot find where the fault is exactly but I know for sure it's on the PCB board because I blasted it with a hair dryer.

How would you check the oil before you crank on the newer non dipstick cars?

Hello dear I asked dan by comment and asking you now My question it is possible to bybass the gateway? Please your clarify

deja vu 😂😂😂😂

How about the voltage regulator on the gateway?

If you put in a new gateway, do you need a J2534 to program?

Hello does that scanner tool come with all data pack
