I've always been a bit unsure of the wizardry that goes on inside a DSG gearbox. What an excellent video, everything is clearly explained, good audio and good camerawork.
Just a tip for those that don't know, in DSG dry-clutch models built before 2015 their is a design issue where the pressure accumulator can crack at the base. This results in a pressure loss that prevents gear changes happening. There is a recall in some countries and VW/Skoda/SEAT are replacing the mechatronics units as a warranty issue.
Old school auto tech here, what a perfect training lesson on dual clutch gearbox, full description of mechatronic unit operation and repair and a good Diagnostic route to find it. Enjoying each one I am running into and love the logic bombs you work through.
Thoroughly enjoyed it Dan. And even though there was a TSB it was good to see the tear down to prove it and that no other apparent issues were present. Thanks!
I was supposed to be on a DSG repair/overhaul training seminar this week, but it was cancelled for obvious reasons... Good thing you came to the rescue!
Came here after seeing others commenting about @DiagnoseDan on Saving Salvages RS3 DSG Mechatronic issue. Am not mechanically minded, but found this video so interesting, and learnt what the DSG gearbox is and how it works. Excellent video, even for those of us non-mechanics!
I got the VW DSG 6 gear box that has given me night mares....this sheds a lot of light thanks @DiagnoseDan will definitely consult in case of any questions :-)
Dan, I have so much respect for your approach to your craft my friend. Not only do you attempt to find the part causing the symptoms, but you always effort to find the “why” behind the problem. Which is what those with truly talented gifts for repair indeed do. I Enjoy all your videos!
I love the way he's so casual about it. Taking the pump apart, etc. The big problem is that a lot of mechanics are afraid to take things apart. They only replace the parts and don't try to know how they work. It's not rocket science, nor is it magic. I love the video. Well done, Dan.
@@Diagnosedan its a simply gearbox, why they can do it right? NOW they using mineral oil....... Same with engine oil. I use still till today mineral oil..... these are better for the engines.
Dear Dan, Thank you for all the things that you show us. A funny side note - I noticed my 65 year old wife has been watching your video's. Recently my wife has started asking questions about various automotive technologies. Last night she asked a question and I got the answer wrong, as a DIYer that happens. She informed my that Diagnose Dan says this is really the issue. The really interesting thing is my wife is not an automotive or technology person, but now I feel secure she would be able to take her car to a dealer and not get taken. The only down side is that I can no longer hang out in my garage telling her that I am working on a problem.... 🙂
@@LeverPhile Except when at a stop. But if stopped on a hill, don't use the throttle to hold the car like you can with a real automatic because that slips the first gear clutch rather than a torque converter.
@@andyanderson1612 Right, neither clutch engaged at a stop. But absolutely no way I'd use the transmission to hold the car on a hill ... auto, manual or DSG ...

mixalis Hi, Just curious. What was the dealers response? I mean, if only a few months old, it should be difficult not to carry out any repair under warranty... (even for VW;)
Dan, there is a simpler way to test for short circuits. Instead of installing a new fuse, connect a 12 V tester to both fuse terminals. In the event of a short circuit, the light in the tester will turn on and stay on (12 V on one side, short to ground on the other). Otherwise, it can turn on a split second, dim and turn off. Thanks for your effort for this video.
very good show DD, i have a 7 speed dsg, skoda 2009 model, people can easily get confused with oils and maybe someone changed the oil and used the wrong oil in the mechatronic's unit, i changed mine just to see the oil at 105000 klms the oil was still the green color oem oil, it was clean, so I put new oil from VW, 1 litre, they say it never needs changing, I also changed the main gearbox oil with 75w whatever which is purpose made for the 7 speed box, was nice and clean as well, people should be aware the 6 speed DSG uses a particular oil made for wet clutches.
Yet again another superb video; you are certainly a master of both automotive fault diagnosis AND producing clear, interesting, informative, enlightening and educational videos, thanks Dan, I enjoy every second watching you work, every single time.

Good video as always ! A recommendation from my side. First remove the TCU from the hydraulic block and only afterwards remove its cover. Inside the sealed enclosure you have either a ceramic substrate with bare die electronic components (gen. 1) or a HDI PCB with the same bare die components (gen. 2). By removing the cover while you are still disassembling the unit you risk touching the board. If that happens there is a high risk of damage to the wire bonds or the actual bare die electronic components which are a lot more fragile than the normal, packaged ones. Keep up with the good work !

Hey Dan , just stumbled across you channel . What a great tutorial on the DSG gearbox . I owned one in a VW EOS 2008 model , never had any problems with it . As a car guy I really appreciate the fusion of the two manual gearbox & clutch setups , controlled by the mechatronic and your very good explanation of how it works . Great work !
Thank you Dan for taking us through this i have always stayed clear of these l now have some confidence to take it on next time one comes to me. Subscribed. Respect from London UK.
Good job Dan! Oil specification is very important! For those manual gear box required GL-4 oil, don’t use GL-5 oil because the additive for EP of GL-5 contains sulphur which could cause wear of soft metals of synchromesh gears, the worn soft metals caused a short circuit in the VW dry DSG.
My god what a clear explanation and video , it is the best tutorial I have seen on you tube .It was so good although I came onto it in error and have niether the same car or fault I sat and watched in amazment well done your the man .
Great video! For checking a 3-phase-motor you can also just make sure, the resistance between the phases is the same and infinite against the housing. Way less effort, same result ;)
This is one of the best transmission videos I have ever seen...your step by step explaianation is another level. Have to subscribe and want to learn more. Well done.. Great content.
Thank you to shared this video. Checked the price of DQ200 DSG trans refurbished (550 pound) and the tcu (125 pound) on ebay to understand the reason why you decided to the refurbish direction. All the other components were in decent shape as you told, maybe would worth a try to change the tcu only. Of course additional programming would need in this case. It would be great to check the damage of the tcu further to assess wether it is repairable or not at reasonable work investment. Somtimes two or three cheap (less than 3 USD per piece) components are burned and that is all. What a waste of material and money. Anyway I enjoy your videos find details very usefull all the time. Keep posting!
No more programming is required if you copy the data over from one tcm to the other. you are correct though the tcm should have been changed only. It was a waste of customers money.
Brilliant video as ever Dan. Sulphurised oil eats copper and attacks copper alloys. Well known fact. Wonder how the VW Engineers missed that? My Dad had a VW Beetle and it kept jumping out of gear. Beautifully made car. He blamed himself for a while for failing to put it in gear properly. I said no, gearbox fault and indeed it was. Been off Volkswagens ever since!
Excellent explanation and autopsy of a dead DSG. They also had a known fault in the early days that caused the DSG to have a incorrect gear selection at high speeds that would cause fatal crashes.
Amazing how many points of failure this transmission has. It's almost like there was a competition on who could make it fail the most ways. Excellent video as always!! One of the best channels to learn from.
@@Diagnosedan Well, designing a transmission that totally fails because it's own gear oil leaked into itself makes you a good contender for first place! Absolutely ludicrous design in this day and age. There's no need for this. None.
@@Diagnosedan Hai. Skoda rapid dsg 6 speed 1,3,5 gears are not engaging properly and 2,4,6 gears are engaging properly. Cleared the error code but came back again and not moving
Am new to your channel. But i son as i saw the detailed way you started explaining 50 % of transmission problems. Are due because of low battery voltage. I was hooked. I thank you. I subscribed already.!!
I've had two cars with DSG gearboxes, and never had any issues with them, but they do give me the fear. I'm not sure how many people are out there who'll do diagnosis at this level. I now have a car with three pedals and a lever that you wobble around. ;-)
I must admit its one of those reason I avoid these new fangled Automatics like the Covid. Old fashioned Slush boxes were slow and burned more fuel, but jesus they were simple. Manual for me too.
@@DasArab whaaa?? since when are torque-converter autos "simple"?? have you ever taken one apart and tried to put it back together, or seen those valve bodies?
I have a 2011 Audi A7, which has just thrown a Gearbox Malfunction fault at me. It's on 98,000 UK miles, and now I'm faced with a Mechatronics replacement, after a VCDS scan, points to Valve 1 on the transmission. This video was excellent, in helping me understand how the device works. Thanks...
Truly excelent, when i count possibility about this Yetti coming from factory with manual gearbox, then we ended without this video, and milions of peoples worldwide can spare on repairs, when something like DSG doesnt exist. Servis intervals are too short... 🤣
40+ years of experience as a professional mechanic, and I can say without reservation: YOU are the man. You did not say it, but you should have mentioned to put the multimeter on AC when testing the motor. I would recommend a milliohm meter and megger as additional tools for the modern technician. Thank you for your work.
Am always impressed Dan the way you keep the workshop clean and tidy and everything that you might need is right there at hand, I wish a lot of workshops would do the same!
When I was an apprentice my boss told me “check the basics first! 90% of most problems are something basic eg. Faulty battery). Thanks for the great video. Very helpful.
Wow I knew the DSG box was a great feat of engineering but never realised it was so complicated. Dan you are a magician sir,,,,truly knowledgeable. Great video. Thanks for posting.
I live in Los Angeles with a 2014 VW GLI with 200K miles. I'm starting to have some drivetrain issues so I appreciate your video. Not that it solved my particular problem. But it was very interesting to watch and very informative. Thank you.
That was awesome, Dan! Very cool to see a DSG gearbox teardown and explanation! I'll stick to my regular old-school foot clutch for now...seems to be more reliable...until my left leg blows a fuse haha :D
Superb video, s3 came in today and the accumulator housing cracked pushing the accumulator forward bending the front cover,A right royal mess it’s made, new subscribers here very educational video , I applaud you dan 👍
Thank you Dan for as always interesting and excellent content! Just like to add, if you like to use an oscilloscope to measure three phases, that you can, if there is no neutral point like the three phase motor in your video, add three equal resistors from each of the three phases into a star point. Well, now you have a neutral point and can connect three channels to each of the phases and ground to the star point made up of the three resistors. It could be done just for fun! ;-) Keep up the good work Dan, love your videos!
Thank you, my friend, for the information. I have a problem with my car, it is byd, the bst transmission system, and I want to test the clutch lever No. 2, please. If I have any other program to communicate, it is preferred.@@Diagnosedan
I have heard that VW transmissions are not designed or built to last, and now I have seen proof. That repair must have cost some serious money in the Netherlands. Thanks for a very interesting video, Dan. And your English is phenomenal.:)
this video was excellent . clearly showing Dan,s high class skill level.. Interestingly the original fully synthetic oil was corrosive .. I hope the expensive Motul 100% synthetic oil I lovingly use on my engine doesn,t contain any corrosive additives . Just for your interest radio control model electric brushless motors are also three phase .. so any R/C electric motor controller would drive the three phase oil pump motor in that Skoda DSG transmission . mr . average mechanic is not going to go to the lengths you go to. even at 76 years young I followed your thinking all through . a double excellent score for you .
What an excellent video! Dan you are exceptionally gifted. I hadn't got a clue about DSGs, mechatronics or any of that but needed to know as my 2014 Audi Q5 has just started playing up with only one side of the gear train driving (1, 3, 5, 7), warning message says Gearbox Fail No Reverse Gear. Leave it and it might resort to normal (1, 2, 3, 4, etc) but then fail again. It's the DSG 0B5 gearbox, which I understand is a wet clutch system (Great explanation of twin clutches, pre-select next gear). All I need to do is get it fixed .................... at great expense here in the UK !!! Getting the right diagnosis may be the first problem. Thank you.
Thanks, I really learned alot about DSG’s from your video. A woman died in Australia when her Volkswagon’s DSG failed on a highway and her car stopped suddenly. Common fault in DSG’s. Can’t believe it was all due to an oil additive.
Excellent video. Clear speech, logically laid out, every step visible. Uncut shot of battery diagnosis was really cool. I'll return to your tidy workshop soon 👍
You just helped me understand my Passat TDI with a DSG, this is the first DSG I have ever owned and before I bought my Passat I'd never heard of a DSG transmission. Tusen takk!
Utterly brilliant education there Dan. Thanks a lot and I mean that. In 1970 I did 'Advanced Motor Mechanics' at college and then ran a little repair garage. All I learned about ZF and Borg Warner auto boxes was that they are so complex you don't take them apart, give them to an expert. Your video here tells me I can probably fix the DSG on my Golf out in my driveway. Now I have no need to go looking for a brand new 1990 Mercedes :)
Hi Dan You are a amazing diagnostics technician which I ever scenes.im working in volvo truck dealership in Australia. and your videos helping me alot for gained up my diagnostics skills. Thanks alot
With videos like this trade schools may go out of business. Excellent content with large amount of nuggets to help out those fearful taking on this twisted form of automated manual transmission.
Brilliant video, this has just happened to my brothers private hire Taxi, 2014 Skoda Octavia 2.0 diesel Auto. Learned lots from this video. Thanks, Vinny. 😊
Always mechatronic failure, although I've seen clutch failure, flywheel failure, slipper bearing failure, solenoid and actuator failure.... the best is hydraulic pump failure! What a mess!
For the accumulator failure you have to be careful with disassemble. Last time we had a lot of problems with customers who putted the wrong oil in the mechatronic 😁
I really like your talking approach to the audience. You make your diagnostic methodology and the reasons for it quite clear. This is quite a bit better than doing it only while you are doing the work. It's very good to discuss the plans first. Thx very much.
The most mind blowingly clear description and diagnosis of the dreaded VW dry clutch DSG setup. I’m no longer afraid of DSGs.

Hai.
Skoda rapid dsg 6 speed
1,3,5 gears are not engaging properly and 2,4,6 gears are engaging properly.
Cleared the error code but came back again and not moving
Am new to your channel. But i son as i saw the detailed way you started explaining 50 % of transmission problems. Are due because of low battery voltage. I was hooked. I thank you. I subscribed already.!!
I've had two cars with DSG gearboxes, and never had any issues with them, but they do give me the fear. I'm not sure how many people are out there who'll do diagnosis at this level. I now have a car with three pedals and a lever that you wobble around. ;-)
😂😂👍
I must admit its one of those reason I avoid these new fangled Automatics like the Covid. Old fashioned Slush boxes were slow and burned more fuel, but jesus they were simple. Manual for me too.
@@DasArab whaaa?? since when are torque-converter autos "simple"??
have you ever taken one apart and tried to put it back together, or seen those valve bodies?
@@raoulrr its simple, everything is on 1 shaft.... and valves follow oil pressure.

I have a 2011 Audi A7, which has just thrown a Gearbox Malfunction fault at me. It's on 98,000 UK miles, and now I'm faced with a Mechatronics replacement, after a VCDS scan, points to Valve 1 on the transmission. This video was excellent, in helping me understand how the device works. Thanks...
Excellent tutorial, beautiful lighting and camera angles! I would love to see you do a DSG fluid change on a VW GTI.
Truly excelent, when i count possibility about this Yetti coming from factory with manual gearbox, then we ended without this video, and milions of peoples worldwide can spare on repairs, when something like DSG doesnt exist. Servis intervals are too short... 🤣
Hello,
Great idea , The GTI has just entered the family and need some care.
Thanks for this great channel

40+ years of experience as a professional mechanic, and I can say without reservation: YOU are the man. You did not say it, but you should have mentioned to put the multimeter on AC when testing the motor. I would recommend a milliohm meter and megger as additional tools for the modern technician. Thank you for your work.
Hello,
Could you please tell e what is a Megger and it's purpose .
Thanks
Tigo
i love how you always find the root cause of a failure.
Thank you 👍
Am always impressed Dan the way you keep the workshop clean and tidy and everything that you might need is right there at hand, I wish a lot of workshops would do the same!
An excellent talk, concise and precise, very informative. Thank you!
My videos teach me a lot you are a real professional.
Please continue to upload more videos
More people like you Dan !!! Amazing enthusiasm and patience. Thank you
When I was an apprentice my boss told me “check the basics first! 90% of most problems are something basic eg. Faulty battery). Thanks for the great video. Very helpful.
If I have to rate 10/10 I’ll even give 20/10.
U explain and show everything very well.
Very helpful !
Wow I knew the DSG box was a great feat of engineering but never realised it was so complicated. Dan you are a magician sir,,,,truly knowledgeable. Great video. Thanks for posting.
Hey Dan you did a great job with this video, your a born natural. Very interesting well done.
Let's diagnose this...... together! back 1 yeasr later.. this information is priceless.. Thanks Dan!!""
Looking forward to 'diagnosing this together'! Or maybe I'll just sit and watch you do it. 😉
Keep them coming Dan. 👍🏻
Abbott Automotive 🤣🤣☺️ look at that, fixed it without even getting my hands dirty. 💪🏽👌
@@HandyC haha! yes, it wasn't a bad one was it. 😉 😂
Why did you let me do all the dirty work😉
@@Diagnosedan we all know you love getting dirty
@@Diagnosedan you were doing such a good job so I thought I'd leave it to you. Plus I was just supervising. 😋
I live in Los Angeles with a 2014 VW GLI with 200K miles. I'm starting to have some drivetrain issues so I appreciate your video. Not that it solved my particular problem. But it was very interesting to watch and very informative. Thank you.
That was awesome, Dan! Very cool to see a DSG gearbox teardown and explanation! I'll stick to my regular old-school foot clutch for now...seems to be more reliable...until my left leg blows a fuse haha :D
Ha ha manuals must be rare in the States.
Yes, they are almost becoming exotic. Most people don't know how to operate a manual, and think of their car as an appliance :(
Well-diagnosed! It's always a good feeling finding the problem. Many workshops would simply replace the unit, or worse, the entire gearbox.
Love watching a master of his craft well done Dan greetings from Australia cheers mate 👍
Thanks Damien😁
Superb video, s3 came in today and the accumulator housing cracked pushing the accumulator forward bending the front cover,A right royal mess it’s made, new subscribers here very educational video , I applaud you dan 👍
Thank you Dan for as always interesting and excellent content! Just like to add, if you like to use an oscilloscope to measure three phases, that you can, if there is no neutral point like the three phase motor in your video, add three equal resistors from each of the three phases into a star point. Well, now you have a neutral point and can connect three channels to each of the phases and ground to the star point made up of the three resistors. It could be done just for fun! ;-) Keep up the good work Dan, love your videos!
Thanks for the comment
@@Diagnosedan Hi, how do you depressurize the accumulator before opening? can it shoot out and injure someone?
Thank you, my friend, for the information. I have a problem with my car, it is byd, the bst transmission system, and I want to test the clutch lever No. 2, please. If I have any other program to communicate, it is preferred.@@Diagnosedan
I have heard that VW transmissions are not designed or built to last, and now I have seen proof. That repair must have cost some serious money in the Netherlands. Thanks for a very interesting video, Dan. And your English is phenomenal.:)
Thanks for watching Paul
Thank you for sharing. I’ve wanted to know more about DSG since I started driving my a few years back. 👍🏻
Thanks for watching 👍
this video was excellent . clearly showing Dan,s high class skill level.. Interestingly the original fully synthetic oil was corrosive .. I hope the expensive Motul 100% synthetic oil I lovingly use on my engine doesn,t contain any corrosive additives . Just for your interest radio control model electric brushless motors are also three phase .. so any R/C electric motor controller would drive the three phase oil pump motor in that Skoda DSG transmission . mr . average mechanic is not going to go to the lengths you go to. even at 76 years young I followed your thinking all through . a double excellent score for you .
Great dissection of the inner guts of DSG.
Dear Dan, do you also get an extra bolt or screw leftover after reassembling things ?
What an excellent video! Dan you are exceptionally gifted. I hadn't got a clue about DSGs, mechatronics or any of that but needed to know as my 2014 Audi Q5 has just started playing up with only one side of the gear train driving (1, 3, 5, 7), warning message says Gearbox Fail No Reverse Gear. Leave it and it might resort to normal (1, 2, 3, 4, etc) but then fail again. It's the DSG 0B5 gearbox, which I understand is a wet clutch system (Great explanation of twin clutches, pre-select next gear). All I need to do is get it fixed .................... at great expense here in the UK !!! Getting the right diagnosis may be the first problem. Thank you.
Nice work Dan, I love your thoroughness.
Thank you very much 😀
Thanks, I really learned alot about DSG’s from your video. A woman died in Australia when her Volkswagon’s DSG failed on a highway and her car stopped suddenly. Common fault in DSG’s.
Can’t believe it was all due to an oil additive.
Can't wait, hope business is still ok, stay safe Dan!!!!
Work is very slow but we are all Safe.
Excellent video, logical, technically sound and easy presentation with no back ground music or silly ego stunts. Liked and subbed. !!
Thank you mr Dan. Found that really interesting. keep them coming please. Take care 👍
Thanks for watching Chris
Excellent video. Clear speech, logically laid out, every step visible. Uncut shot of battery diagnosis was really cool. I'll return to your tidy workshop soon 👍
Keep those great videos coming... my wife is driving me up the walls!!!
Ha ha ha 😂😂
I want to start a small local shop and I love your videos reminds me of automotive school back in 2009.
Brilliant mate that’s a great video, learnt a lot as usual!
That's great Michael
You just helped me understand my Passat TDI with a DSG, this is the first DSG I have ever owned and before I bought my Passat I'd never heard of a DSG transmission. Tusen takk!
Thank Q Dan the man done it again.... very informative Webinar.....
Thanks for attending
Dan , after watching this you were indeed correct! MODERN CARS HAVE GOT STOP STOP TECHNOLOGY! Great diag Take care
This transmission makes me appreciate my 2001 Mercedes transmission.
Thanks for watching Marcus
Nothing more Bullet Proof than 722-5 Transmission.
Utterly brilliant education there Dan. Thanks a lot and I mean that. In 1970 I did 'Advanced Motor Mechanics' at college and then ran a little repair garage. All I learned about ZF and Borg Warner auto boxes was that they are so complex you don't take them apart, give them to an expert. Your video here tells me I can probably fix the DSG on my Golf out in my driveway. Now I have no need to go looking for a brand new 1990 Mercedes :)
This is a great channel, I wish you done videos more often!
Hi Dan
You are a amazing diagnostics technician which I ever scenes.im working in volvo truck dealership in Australia. and your videos helping me alot for gained up my diagnostics skills.
Thanks alot
Maybe you can do a dq250 or any of the wet clutches.Cheers 🍻
No problem 😁
6 speed wet qlutch DQ250 would be cool and interesting
With videos like this trade schools may go out of business. Excellent content with large amount of nuggets to help out those fearful taking on this twisted form of automated manual transmission.
Thanks for watching 👍
5:55 Too many useless devices making our lives more expensive!!!
Brilliant video, this has just happened to my brothers private hire Taxi, 2014 Skoda Octavia 2.0 diesel Auto. Learned lots from this video. Thanks, Vinny. 😊
29:13 Me, when a new video is out.
me to :-)
Never forget to celebrate your accomplishments.
Ha ha ha😂😂
You're the man Dan. We badly need someone like you here.in Vancouver, British Columbia, Canada. Do you know of transmission guy like you here?
Always mechatronic failure, although I've seen clutch failure, flywheel failure, slipper bearing failure, solenoid and actuator failure.... the best is hydraulic pump failure! What a mess!
You forget the broken Acumulator 😉
@@Diagnosedan Totally, that looks awesome when they fail.
For the accumulator failure you have to be careful with disassemble. Last time we had a lot of problems with customers who putted the wrong oil in the mechatronic 😁
I really like your talking approach to the audience. You make your diagnostic methodology and the reasons for it quite clear. This is quite a bit better than doing it only while you are doing the work. It's very good to discuss the plans first. Thx very much.
50% of all roadside break down are related to battery or charging? Sound like someone is trying to sell something I don’t need.
That is actually true especially in winter or during a cold snap.
From Holland verry clear diagnostic as clear as water 💧 this man is a masterr👍👍
Thanks for watching 👍
👍👍👍
