DSG Transmission - Explained
HTML-код
- Опубликовано: 28 сен 2024
- What is a DSG transmission? How does a direct shift gearbox work? A DSG transmission is a dual clutch transmission used by Volkswagen. A DSG uses two wet, multi-plate clutches to activate separate drive shafts which send torque via the even or odd gear sets. Because the gear sets are on separate shafts, this allows for preselecting the next gear, allowing for nearly instantaneous gearshifts without a total loss in torque. DSG tranmissions operate a lot like manual transmissions, but they are electronically controlled and thus the gear selection can be either automatic or manual, but does not require the use of a clutch pedal as this is all activated automatically.

NEW VIDEO EVERY WEDNESDAY!
This is probably one of the best demonstrations of a VW DSG transmission I've seen yet on RUclips.
Thanks for having me on the video and hanging out at the garage. :)
Always a pleasure dealing with the elderly.
Engineering Explained what's that sonny....
Excellent "explainer" video guys. Thx.
HumbleMechanic Would you ever do a video discussing the effects and pros cons of a dsg tune??
I see a lot of CO brewery stickers on the toolbox. Are you here in the state?
I am amazed at how well you explained that! I have always had a vague explanation from others, and as an engineer it always bugged me. Great explanation, and having one to SHOW was amazing.
I'm a retired ex mechanic who spent the last 15 years of my life as a mechanic Repairing/Reconditioning Vehicle Transmissions It was fantastic to watch this video As it supplied so many Flashbacks But also Looksees into what's happened since I left the job THANK YOU
Hurts my brain trying to understand is wizardry, the designers of this are incredible
They are called engineers. If you like the idea, look into "machine design" in engineering, and engineering school is awesome :)
There's a video explanation of ZF 8HP on WeberAuto channel. Check it out
Honestly I think I picked up a good portion of this surprisingly. Whenever people tried to explain how a manual trans works to me when I was younger, trying to learn stick, they honestly just confused me so much more than if they told me how to use the clutch and not explain how the transmission is actually working. However if I watched this video it would’ve made much more sense now.
same here bruhhh xD xD
The cost to maintain one also incredible
As always, a simple and efficient presentation of a comparatively complex engineering solution. Keep up the good work!
I really liked how you half- built a DSG to allow for a very clear and easy to understand visual of how the system works :) This allowed me to help explain how a DCT transmission works and why he was greeted with hesitation
Collaboration of HumbleMechanic and EngineeringExplained... Internet Win!!
Jeff R Thank you :)
I just got a DSG car (ford fiesta) and have driven a 5-speed manual for many years. I heard a lot of complaints about the dual-clutch being jerky and not good at low speeds, but I've driven this 'new' car like I would have driven a stick, and it's not given me much problems. The clunky sounds it makes always makes me cringe, but this video really helps explain how my transmission is working. I've heard "it's a manual that shifts automatically" but this really gave me insight as to what that actually means.
Thanks!
VW's DSG is great to drive. Drove a GTI with one and I fell in love with it.
Hear That? Yeh but wait till it breaks....wallet emptier

I have an 06 Audi tt with dsg and really like it a lot . I was happy to learn that the C8 Corvette has an 8 speed DSG. I'm a guy who grew up with, and really like the standard transmission , but if you only have one car you drive daily there is a point in your life that you get tired of pushing in the clutch in stop-and-go traffic just to move ahead 20 ft. For me the DSG transmission is the best of both worlds. Sport mode regular mode paddle shift bump shift offers a lot of variety in a lot of fun without wearing out your knee. My brother-in-law had a Mazda Miata that he put 250,000 miles on with a standard transmission. He needed to have his knee replaced. I asked my sister which knew it was, she said his clutch knee.
Thank for this amazing video. I love the way you explained the transmission with an actual unit.
looks like this one had the same problem as my dct box has currently. the synchromesh rings are worn out causing heavy grinding on the thin gears which are needed so the shifter rings can engage upon them. this problem is pretty common for dct transmissions because of the frequent need for oil change (every 60k km) which IS NOT specified by the manufacturer. If the mechanic over sees this and your driving style is on the sporty side the synchromesh rings will start to wear out way before you hit the 200k km. The brain of the gear box does not know if the synchro is worn so it shifts without giving enough time for the gears to line up which is something you can do with a manual box. thanks for the video this is exactly what i needed to see.
I really enjoyed this video, it has two of my favorite youtube hosts (Y)
Appreciate it! Charles is a rad man.
+Engineering Explained ---Ok so I get DSG, I have a 2014 gti drivers edition and..... what causes DSG farts. I had my resonator deleted today, basically so I could just have a deeper sound, and it does sound really nice, but can now hear the farts more. thanks
As has long been explained by lot of people, that is how it works, there are very funny videos on youtube about DSG and farting minions, check them out, and deal with it.
What is the actual cause of the dsg fart?
@@mbulelomankonkwana8038 First, the ECU cuts timing during the shift, but fuel delivery continues for a brief moment. So, some unburnt fuel makes it into the exhaust, which is hot. So the fuel gets ignited, making the sound. The reason for the timing being cut is to prevent the engine from revving while the shift is occurring.
Great explanation all around.
A more common preselection error would be gently accelerating to close the gap on a 2 lane road before reaching a passing zone. All indications to the computer are that the next higher gear will soon be more efficient at a higher speed. When you reach the passing zone, if traffic is clear, you step on the gas to use more power and shorten your passing time, best done in a lower gear.
Also, I question the location of the gears as stated, you might check those. If 5th and 6th are run from the same shaft, there's no physical possibility of preselecting 6th.
Honda claims on their DCT all even gears are separate from all odd gears to achieve the same effect. I have not looked at the DSG, but in an attempt to achieve the same task, it just doesn't make sense for any consecutive gears to use the same power shaft. Well, we hope there's a stop before reverse anyway, but not the others.
I used to have a Mark5 Golf GTI. Occassionally it would take 1-2 seconds to engage after putting my foot down after creeping forwards waiting to turn at lights. I think you nailed the explaination in that the conntrol unit was confused and expecting to down shift. The dealership had absolutely no idea!
Also in sports mode the downshift from 3rd to 2nd was very harsh as it changed as a much higher RPM.
Now drive a Renault Clio RS, which I think has a similar assembly
Thank you Engineering Explained
I appreciate the video you had made earlier with the dual clutch
And now a better understanding video.I am only 16 and i know almost everything about how car works
Because of you. Its so much better than watching illegal car races
Salute to you Jason from Engineering Explained and Charles !!!!!
Jeremy Yeo Very welcome, glad you enjoy the videos!
Jeremy Yeo Thanks man!!!!
thanks for disassembling the transmission.
Always wanted to know how the hollow shaft looks like.
This shaft has to take a lot of force. Is it extra treated ? Better hardening process, another steel, or so?
Great video! I am an engineer working on the GTR gr6 transmission and you explained how the dsg works very well.
Awesome! Let me know if you or Nissan would be interested in making a video on it! Cheers.
Engineering Explained I work for a private transmission company that is not associated with Nissan, but we almost exclusively work on/build the gr6. Unfortunately most of it is confidential but I will surely see if the logistics of doing a video with you are feasible!
Jacob Shields OrangeFiero Sounds good to me! You'll find a business e-mail on my "About" page of YT. Thanks!
Jacob Shields OrangeFiero
COOL!!!
Very interesting. I like it. But you'll never change my mind on a conventional manual transmission. I just love the feel of a clutch pedal under my left foot and a shift knob in my right hand. "If it feels good do it!!"
Joseph Inman I don't think you'll hear any resistance from Charles or myself. We both love our manuals.
Engineering Explained Definitely can't beat a clutch pedal and a manual gearbox.
The best DSG transmission video I have seen, puts everything into perspective
thanks guys! was experiencing that "jerky" behavior every now and then and this provided a great explanation for what's going on in the engine when that happens.
Love the DSG in my S3...so smooth and quick, yet had some of the same quirkyness of a manual (bite on initial pull off).
Joe Joe love mine too in S3 2016
Nice job tag-teaming and explaining the DSG. As one with auto and manual trans experience in a previous life, everthing made perfect sense! :D I WAS disappointed not to see a duet from you two as an encore! ;-)
So basically its a manual transmission using an automatic transmissions clutch packs and pistons. With the combination it might last longer then both wear wise because you don't have to worry about all the clutch packs a normal automatic has or the clutch going out like a manual. Since it's all computer controlled, as long as the electronics hold up, it should have over 100,000 miles of life or 200,000+ maybe.
Just don't bottom wash your car
you would think.....
Hahahahahahahahahaha longer life than a manual
My brother told me about the encounter with the engineer that initially had the idea of the first dsg. He described me a truly genius person that was passionned by mechanics and quite socially awkward. A little bit like a mechanic -crazy Sheldon Cooper.
You should do a video on the fabled CVT transmission. Loved the video btw!
Finally I know why it would sometimes take a second or two to get into gear! Thank you!
Thanks for the video... My car have a DSG7 and it s great, so great I barely miss my old manual impreza
good job very clear , I understand how a gear can be pre selected now, I didn't understand how that was possible before
humor and engineering both combined. great video. thanks guys
Thanks :)
HumbleMechanic you very welcome, nice presentation,

wow I never seen a dsg taken apart before...its seems simple yet complicated...I had to watch a few time to understand everything...thanks for the video
Could you explain the engineering decision to use gears that have angled teeth vs gears that have perpendicular teeth (similar to lego gears, for lack of a better visual example)
+Matkat Music helical gears are significantly quieter, thus far more common (but more expensive). Straight cut gears are cost effective, but very loud, so typically only used in motorsport, or for reverse gears.
Very cool. We need a video showing how the valve bodies for Automatic Transmissions work. I don't think your channel does animation videos tho...
Ever watch world rally racing? That is what straight cut gears sound like.
yes straight cut gears have a distinct whining sound... almost like a supercharger if you will. you can really hear them in a Honda while they are in reverse
True, WRC are mostly strait cut- and sure adds awesomeness to in car audio :)
Thank you as I had no clue what '11spd DSG' meant on an an auction site I was looking at!
Good Job Guys, I had my trainee's subscribe to your page to help them grasp some of these topics. I think I meet Jason at SEMA in 2013 with a N54 crazy looking Twin turbo setup. Hows everything going?
Escondido German Auto Thanks for sharing the videos. I've never been to SEMA, though I'd love to!
i drove a 2015 Skoda Octavia diesel in Scotland and I think the Skoda used this trans. The car shut the engine off instead of idling at a stoplight (should have seen the looks on our faces first time it stopped) . Seemed to work real good, but had a couple of scares on steep hills when stopped. You had to release brake to restart engine, but then car freewheeled backwards and couldn't seem to cut back in forward. Took a couple of restarts but finally pulled forward, scared the guy behind too. Might just have been my lack of experience. Put about 1800 miles on. Seemed powerful enough for a fair size car with only a small engine, hauling 4 adults and lots of luggage.
Charles is awesome! Jason I liked this duo explanation! Great work! =)
watched so many explanations before this never understood how it could preselect gears until i watched this one
I really dont know who can put any mean comment, you guys just rock! Keep it up!
loving this guys beard.
astonfan188 awe, thanks :)
HumbleMechanic Thanks for making this video, I'm doing a college essay on the Volkswagen DSG gearbox and I found this video explained to me how it works :)
Great job guys, love the way you explained DSG.
Great dissection of the popular DSG transmission system.
When gear lever is moved to the park mode, what actions happen inside the box? Does it lock the output shaft?
There's a gear on the output shaft and the transmission sticks a pawl (piece of metal) in it.
Little gearbox fairies come out the woodwork to throw a small anchor. When you select D, the fairies go back in their box.
Hi Jason,
I just bought a 2017 audi a3 e-tron which is a plug-in hybrid with an interesting triple clutch gearbox DQ400e (also used in Golf/Passat GTE).
I found some information on it (looks like electric engine is integrated with the gearbox?) but I'd LOVE to see a video explaining this drivetrain a bit more. I think it's quite unique also in the way the power from the electric motor goes to the wheels through the gearbox which usually is not the case (unless it's a CVT maybe).
Anyways if this seems interesting, please make a video on it. Keep up the good work! Cheers from Poland!
Charles has one epic beard
MrTURBOJOHN Thanks :)
HumbleMechanic didn't expect you actually replying. You did a great job in this video.

Gerçekten çok güzel videolar çekiyorsunuz Hepinize çok teşekkür ederim Türkiye'den selam Oto Servis olarak sizlere takdir ediyorum
Drove a 2023 Tiguan with DSG and I didn’t like it at all. It’s not as smooth as a traditional Automatic, and not quite as intuitive as a person driving a real manual. For some reason when I came to a stop it was clearly jumping from 2nd to 1st, giving a little extra oomph against the brake pressure leading to a secondary small lurch. Dealership said it’s common when you first drive them and I’ll adapt to it?!
Make sense, no wonder my Passat some times has kicking feel when I step on the brake and then follow by some gas. Explained a lot.
Question: I thought you said that the main purpose of a dual clutch transmission is to separate odd and even gears for speed, but in this video you state that the output shaft #1 had the gears 1, 2, 3, and 4. The other shaft handles the rest of the gears. And one clutch is connected to one shaft, which means that the purpose of this DGS is just wrong. What am I missing? :)
That's actually 2 shafts, one above the other, just like in the whiteboard video. 1 & 3 on the top shaft, 2 & 4 on the bottom.
They didn't explain how 5 & 6 work on an extra shaft, I can only assume at least one of the first four gears acts as an idler???
Anyway, all those (big) cogs look like loads of rotating mass, you'd barely need to engage a clutch to keep feeding torque to the wheels!
as I understand it, the shafts that separete the odd and even gears are the input shafts (the concentric ones), not the output.
I need to see the bloopers reel for this video. Great video featuring peak engineering bromance.
best explanation on DSG i can find, thanks!
You explain the engineering and the biggest problem (for me ) with DSG- that is the delay when you come off the throttle and then back on quickly. This is a HUGE engineering flaw IMO and one that has totally put me off my DSG and I will be going back to manual ASAP so I have total control.
I've seen dual clutches before. So I had knowledge of how they work as an install option with racecar with manual trans. I didn't know the newer "twin clutch" tech drive 2 separate input shafts. I run a 92' 4g63t motor and would love to fit/engineer a Evo X trans to my engine in my 94' awd eagle talon.
as far as pre-selecting the next gear is concerned, didn't the old french car 'Talbot Lago' had one of these.. u select the next gear with the hand lever BUT the gear change doesn't happen yet UNTIL u step on the clutch pedal.. they say it was good for racing, cause u already select the next gear, and activate it later on by pressing the clutch pedal
Learning so much from your videos! Thanks again from a fell Portland Native. Hope to run into you someday.
It's so easy to understand. Its a bit like: Your heel bone connected to your ankle bone, Your ankle bone connected to your leg bone
you didnt explain how the mechatronics transmission control unit works pre select the gears. You provided examples did failed to explain how it makes those choices. Other than this, i love this video and as an owner of the tdi diesel, gotta say one of the best engines I have ever owned.
Sad to think that in a few years, all this knowlege will be lost to history as all vehicles are electric with no traditional transmissions.
Thanks to environmental alarmists and Elon Musk, all cars will become as boring as Samsung smartphones. After that happens, I stop caring about cars and just buy the cheapest a-to-b ipad on wheels.
@@betterbeavailable that has always been the case. It is just a different power plant. Gas is not going anywhere for a long time friend, but i do think that our car hobbies might get a little more expensive as time goes on.
Sad? It will be a relief to get rid of this mess!
@@betterbeavailable ok grandad
Hopefully hydrogen cars will get more popular
Great video with those gears, selectors and shafts on show.
Amazing how "small" the clutch friction disks to be transferring the power from a car engine... I imagine the pressure pressing the disks together must be great!
Can confirm, DSG is great. Had it on my Polo tsi, smooth and fast, very good.
Hi it's been 9 months. Is your Polo DSG still running well?
S-Tronic is love.
S-Tronic is life.
I think what people describe mostly about DCT transmission is in stop an go traffic especially if they were used to a torque converter tranny that is only felt in first gear and reverse Charles you should mention that there is a version in the Jetta hybrid with dry clutches and seven speed.
V10PDTDI I avoid talking about the Hybrid at all costs LOL! :)
what are your opinions on dual clutch transmissions? are they good/reliable?
Spawn223311 Transverse 6 speeds (wet clutch) are very good. Some early versions had problems with their mechatronic units, though they have been adressed and fixed. They are very strong boxes and this have been proved from the tuning scene. Stock clutches can handle huge amounts of torque if the box has been remaped. Gears are also pretty good for a 350nm rated gearbox. They can handle almost 750-800nm before giving up. Keep in mind though that they need to be serviced every 40k miles (fluids and filter) and this is really important for gearbox life.
Later 7 speeds (dry clutch) are not so reliable.( Im not talking about ttrs/rs3 dq500 units, those are 7spd wet clutch and really good) They have some issues with their clutch packs and their mechatronic units (completely different from 6spd) seem to fail often. I really hope that vw has adressed the issues.
Keep in mind that im talking about transverse versions. I dont know about longitudinal found in audis
they suck
it's really neat to see how all these things work, love these kind of videos.
The two greatest remaining mysteries of my life are electricity and gearboxes no matter how explanations are presented in either reality or animation. Admittedly I own a Suzuki with a DCT and it’s remarkable. Fast and economical. Might just leave it at that.
Last Wednesday, my Volkswagen's dsg broke while driving on the highway.
Compared to the classic AT, dsg is crap and last twice less km, like anything in modern cars vs older ones.
What mileage was on your car when it broke?
What happens if I want to shift down 2 gears??
Great video.
Pity VW didn't put as much effort into other technologies as they did into dieselgate.
so what is causing so many to fail, VW has recalled so many DSG fitted vehicles world wide?
Robert Smith its german...designed to break like most german cars
@@alanbrand7681 haha, sure, unlike American crap that no one in the world buys
Aleksandr but it doesnt change the fact that germans are trading on their past reputation
@@alanbrand7681 I've always owned German cars from different years (1999, 2010, 2017) and I never had any major problems with them because I service them properly and regularly, same with people I know, even with non German cars. Maybe when you start taking care of your car, your car will take care of you
i swear this is my fav channel
Perfect explained!! Congrats folks!!! This "delay" issue...is definitely there...tks
I just rebuilt my first DSG. Came out great. Really simple unit. Probably undershot the price a bit. Think I can charge slightly higher on the next one.
+Lynx Star Automotive (Gabe V) pretty much a huge motorcycle clutch pack?
Jthumper Manual transmission with a huge motorcycle clutch pack for a torque converter.
+Lynx Star Automotive (Gabe V) Simple? Like simpler than the video makes it look or as easy as a standard clutch, Because from the video I don't think you could pay me to work on this (that's why I'm not a professional mechanic :)
uncreativename Well in a mechanic's world. Simple. I've since done 3 more. I am knocking them out same day. Pull it in the morning. Ready to go back in by 3:00pm
How long do they last? And what breaks first the DSG or the transmission?
An amazing piece of technology. I think it is only a matter of time before all automatic transmissions are based on a similar concept (unless everything becomes electric).
Does the DSG differ between models within the VW group? Maybe VW vs Audi? If so, how? Loved the video! Thank you.
I just found out my new 2010 vw cc sport has this dual clutch dsg and this explains it great!!
Hi there! Can you please explain the proper ways of driving DSG vehicles in order to minimize faulty of the gearbox. I think it's crucial to share this kind of knowledge to DSG users.
Absolutely agree,, i am considering a vw ,, and would love to know if i am making the right decision
I've been driving with a DSG for the last three years in a now 8 year old car. I drive it pretty hard sometimes and take it easy sometimes. It's great in auto when you want to relax but if you want to go fast I click the paddles and it changes gear amazingly fast. I love it.
Two smart guys made a great video. Thank you
This guy sounds like Bill Nye.
The science guy...?
Install a stand alone oil cooler and a 2nd line filter,runs so much cooler,clutches clamp harder,shifts smooth, and the extra oil and filtration give peace of mind
Thanks for that, very explanatory video. Perfect for helping with my college assignment
I have the DCT in my motorcycle and it's basically the same thing. Lot of fun to ride.
Would be great to see an explanation of how the ZF8 transmission works and compare it with the DSG :)
Both of these guys are awesome. Keep making videos together if you can, please
Serge Rey Thanks, I always have a blast with Jason
thank you. Question: when they say a service on a VW DSG transmission is $500, that needs to be performed occasionally, what does this entail?
Great video - finally someone has explained it easily.
So if the Dual-Clutch Transmission does the shifting why would some cars still have the paddle shifter? is it because of more driver control? I know that F1 cars are DCT but have paddle shifters. I mean ultimately, wouldn't it be self-defeating for a DCT to be controlled manually again ?
+TheGreenCommunity It's nice to be able to control what gear you're in (that's the only way it works in motorsport). Also, F1 does not use DCT.
+Engineering Explained Thank you very much for your response. I assume F1 drivers also use manual transmission because they have more control with manual then ?
So basically even though it's classed as automatic it does have a manual mode?
@AmDolan That's correct.
+Am Dolan VW call it Tiptronic, basically you move the gear handle to the right (while it's on D) and then push it forward/pull it backward to control the gears manually. (Or if the car has flappy pedals then you just use those).
works even in a better way than i thought. thanks for that explanation.
Excellent job explaining the process, and thanks for the demonstration. Cheers!
this gearbox is a disaster !!
yes its very smooth, very fuel friendly,
but, it breaks a lot!! no matter what the car is VW, Seat...etc a lot of complains specially with the heating issue when driving on a low speed continuously or in traffic
you'll have to shift it to manual in traffic or sport mode just to keep the clutch for longer time period
Early VW and Audi models did have problems but most if not all were rectified by 2014. I have a 2015 S4 DSG with 82k haven't had an issue yet. The problem is most people will not service the DSG under the dealer recommendations therefore shortening the life of the DSG causing premature failure.
Actually the first clutch Disengage before the second clutch engaged. You can’t engage two gears at the same time.
To think someone thought this up to invent is incredible.
You know I've had a 2017 gli for a year now and I've always told my friends that this is an automatic that treats itself like a stick shift. Its nice to know how hard I hit the nail on the head before watcning this lol
Great explanation! Clear, great demo , good to see all the parts.Thank you
Amazing Guys it's exactly what i'm looking for about DSG, I like a lot your videos and channels, actually suscribed in both. Thanks a lot!!!
Bryan Nuñez Thank you. Glad you liked it.
As much as these types of transmissions being claimed are better I personally hate them, in slow moving traffic they are all over the place in gear selection, out on the highway when you go to overtake a slower moving vehicle when the computer sets the gear box up to go to the next higher gear and you put your foot down and have to wait for it to wake up and select a lower gear, at least with a traditional auto trans there is no waiting for a lower gear to be selected, you put your foot down and done, and with the 3 vehicles I've driven with these DSG trans non of them where smooth with gear changing thud and clucking noises every gear change, feel the gear change shock through the vehicle makes for unpleasant driving experience and a personal dislike for DSG trans.
Damn I was really wanting a VW DSG, either a GTI or GLI but this comment section is pushing me away.
Bigshows93 Same here. I’ve driven a manual for a little over 5 years now and I wanted my next car to be a DSG Gti, but I’m not so sure about the DSG now..
Sooo you basically like the traditional auto transmission? The DSG feels like this because it's like a manual transmission without a clutch pedal! If you hate all the jerkiness, thuds and clunking definitely stay away from a manual you'll hate it ;)
Thanks heaps guys. Totally make sense. What a great design!
Thanks guys! Great vid! I`m planning on going back to school for a career certificate in auto repair. I`m a little scared because it`s a career change, I`m 44 now and worried about the career change at my age. I wanna open my own shop and work for myself.
Don't worry about it, the industry needs some maturity. But not too much ;)
Hey where can i get good mechanic tool sets but without paying an arm and a leg for?
VWGTI
HAHA, I want to say that you can't ;)
I started with Craftsman. I still have many of those tools today.
HumbleMechanic Thanks......and thanks for the encouragement too. :(
Just wanna say that if you wanna go into automotive make sure you love it more than anything or you won't wanna stay long. Lot of BS in the automotive industry. Find a good shop and you should be good.
you should explain why these transmissions are unreliable as f**c.
+TheRealDeal Then you should show the evidence that DSG transmissions are unreliable as f**k. You are asking for an explanation which relies on your statement being fact. In your evidence you should give the failure rate compared to other transmission types, the average service lives, the number of failures per vehicle service life, the number of days off the road due to DSG failure compared to other transmission types. Also you could include number of warranty claims for DSG failures and the average cost of DSG failures compared to other transmission types. Do you have personal experiences with DSG reliability? If you have had a vehicle with DSG, how was the car driven? Was it serviced properly, was it thrashed/abused? How many miles did it reach before failure/problems?
They are less reliable than a typical 4-speed torque converter transmission because they are more complex and have clutches. Drive both a Mk6 & Mk7 GTI with DSG. The Mk6 is making a scratching noise upshifting to 4th. That said, dry dual-clutch transmissions are the ones with major problems. They have no oil bath.
+TheRealDeal had to replace the mechatronic control unit on my a3 2006. Fortunately it was real easy to replace and code, but the price just for the unit alone was $1285. Unit started failing at 70,000 miles, car now has 98,000. Doing some research, I see that its such a common issue that Audi/VW extended the warranty of 2007 - 2013 for the dsg. Also, if the new a4 is any indicator I think Audi/VW will eventually stop using dsg.
+TheRealDeal The clutch is unreliable, because it is an expendable part and always needs replacement after some time. All people I know who have DSGs and are driving in Moscow traffic jams, are going through clutch replacement about every 80.000 kilometers. Maybe their clutches would last forever if they have driven only on highways.
The competition between DSG producers is not high yet, so they don't care about the cheapness of repair at all. It happens so that for my manual Lada Samara the clutch was engineered like expendable part, and the new clutch costs 18$ + 2 hours of mechanic's job, but in DSGs the clutch is engineered like a part of gear box, so the new clutch can cost more then 1000$.
Илья Медов The same for my ford escort, when i swapped 2.0l engine in it, i also changed the clutch. On a car simple like lada classic for example changing the clutch is almost as simple as changing brake pads.
This was very interesting! Thanks for making this video!
But not as reliable as the Japanese transmissions
As a Golf DSG owner. Watching this makes me worried about repair bills. Looks a complex bit of kit to fix.
