Lmao don’t worry jego. My first car was a 2007 jeep compass and the cvt junked out on it. Had no clue what a good car was at the time. Now on my third strong car ‘22 Hyundai Elantra N DCT
A massive Thanks for sharing that video, it has really helped me understand the DSG box and the way it works. I have just brought a skoda yeti 2016 with a 1.2 DQ 200 7 speed dsg box and I never had any idea what was going on in the box. I understand the workings of everything now. when im out on the road I can understand what going on. I really appreciate you sharing this👍👌
Thank you boss. This is the best explanation to date on TH-cam. That clutch readiness precision is insane engineering. Those pneumatic actuators inside the gearbox need to perform precision operation under all kinds of stress conditions. That's pretty impressive
This is another one those urban legends that pops up and I always look at the person telling me with the “yes, I can’t imagine ANYBODY in the engineering department over there EVER thought of THAT” face.
Thanks, very informative video and I like the manner in which you did this.👌 I guess no need for me to put the car in neutral any longer when sitting at a red light, was really scared that I might damage something in the long run💯
Nice video, it would be cool to see how reverse is done. I know the DSG uses clutch 1 for reverse gear and I have noticed if you are not completely stopped and the transmission is still in 2nd gear it will be slightly quicker to get into R since it doesn’t have to disengage the clutch first, but this was on a Gen 1 DQ250.
The only thing people need to worry about/realize with these transmissions is when in bumper to bumper traffic, you dont want to constantly inch your car forward. That causes excessive wear on the clutch as it's constantly doing partial engagement. Thanks for showing just that.
I don’t have a VW but I have a car that uses wet dual clutch transmission. Would it be better to go on neutral rather than just hitting the brakes or engaging the auto hold function and creep through traffic?
No way they designed it to slip in a stand still, the pressure is only there to stand by. Put it in drive/sport/M and hold it with your brakes as long as you want
Great video . The logic and common sense of the explanation prove to me that you know very much about this . Reading the comments some are pretty on point as well . Good video.
Great video in understanding the dynamics of DSG transmission. Now the I am armed with inside knowledge of this transmission, I am curuous to kwow what would be best mode to drive in bumber to bumper traffic to increase the longevity of the clutches? I believe drive mode would cause many shifts. Will manual be better than sports?
I had a old 2007 VW with FSI motor and DQ250, the flywheel was worn out, I’ve noticed the clutch didn’t completely disengage at a stop and created extra heat unless put in Neutral. But now I have a new 2017, with same DQ250 (obviously updated and not worn). I can feel the clutch completely disengages at a stop.
Thats because your older car needed to have had a clutch adaptation done. Something that any good euro mechanic knows how to do. That would of told the car where the bite point is. Every DSG should get an adaptation done every DSG service i.e. every 4 years or 60,000km/40,000mi. This teaches the DSG where the bite points are on both clutch packs as they wear out over time.
@@timeformetoact6I think that has to do with lack of cleaningness in the work procedures and improper flushes or wrong level left and the use of a different DST fluids. As in regular hidraulic oils, mixing 2 different hidraulic fluids can cause foaming, because of the 6 plus liters the dsg uses on a regular change only 4.5 liters are changed. Further more the oil level setting procedure has to the done with the engine running at a specific temperature. So, without being annoying, make sure the mechanics have enough experience and minimally know what they are doing.
Another great video! It also now makes more sense to me why we need DSG tunes for more power now too. If they came from the factory already "DSG Tuned" with more clamping power then would be required perhaps it would seem to me at some risk of stalling the engine, or at least like the engine output isnt matched for a nice transition with the torque slip, especially at higher Tq demand/spirited riving.
Havent thought about that but you may be right. Ive notice since being tuned over a year now in 1st-3rd the shifts are much harder and slower then the higher gears. With what you mentioned that actrually makes sense as lower gearing makes more torque then higher gears. So it has too clamp harder in lower gears for that very reason. I find into 4,5,6,(never reved out 7th) shift instant and dont lurch your body. But into 2 and 3 its like 100%power cut for half a second then 100% power on.
Hello, i find very interested and helpful your data! I will like to make a question. This time in video, that you explain the all thing about engage and disengage of clutch .. you use the electric handbrake? I guess that you don't use it.. but if you use it , in the auto hold function, what it will happen when you are stopped and waiting (maybe) in the red light? Sorry for my english! I hope to understand my question!
Could you please also explain that how to use DSG, bumber to bumber traffic.While waiting for the green signal, do we need to put it on N as I see that clutch engagement can be avoided which helps long life of DSG?
Excellent video. First time you can actually see difference between N and D. For me, the only question is why there is pressure in clutch, when you are in D and breaks engaged? What that pressure means exactly? Clutch is engaged still somehow, but not slipping? And torque gets generated only when you drive? Or torque will be generated when clutch is slipping?
I can explain for that. At a stop and the car is in drive, there is clutch pressure because First gear is selected and fluid is pumping in order to cool the DSG when rolling. I did a test and on my DQ250, in D I consume 0.36 Gallons per Hour at a stop and in Neutral I consume 0.28 Gallons Per Hour.
So in the end, what do *you* do when waiting at a red light? What do you recommend? I personally decide to go the neutral only if I know it's going to be a long wait, like more than 40-60sec on the traffic lights' timer. If it's less than that I don't even bother.
if you had a manual....would you hold the clutch pedal down that long? treat being in "drive" with brake pedal on as if you are holding down the clutch pedal. It will wear the release bearing.
This makes me wonder which is better over all for clutch and possible engine. Putting car in neutral and leaving engine idling at a stop. Or alternatively leaving in drive and letting auto stop kick in so engine stops completely and clutch not in use at all?
Always wondered what strategy was used, I have a 2015 POLO GTI that seems very "aggressive" in it's strategy for shifting causing me to worry about the life of the clutch packs.
@EVERYTHINGcpo Does using sport mode helps DSG gearbox to last longer because of less gear changes happening? Even though it comes at the cost of higher fuel consumption?
What can damage the clutch is stop and roll or go type driving in heavy traffic sitting at a stop the clutch decouples but if the car is moving slightly it tries to engage the clutch but slippage happens cause it doesn't fully engage thus causing some ware
Thanks for the data. Have you tried any while utilizing the brake “hold” feature. I keep it on and find myself removing my foot from the brake pedal until the light turns green and then I just press the throttle. I wonder if I’m allowing the clutches to go into that “ready to engage” mode prematurely
Hey my dsg jerks and feels like it’s going to stall from complete stop. No other point doesn’t do it. Have tried a few different possibilities but nothings changed. Thinking of getting vagcom cable to do basic reset. Not sure what to do
LoL. It doesn't. the gear level is a electric switch. Mechanically the only thing it actuates is the park locking mechanism inside the gearbox. But the lever is locked off sliding into that position until the wheels are completely stopped. Just make sure to - Press the brakes properly when sliding the gear lever in or out of the P position.
Great video. Very useful. Do you how this relates to the auto hold feature fitted to VW's. Is it the same as holding on the foot brake i.e no clutch engagement
And what happens when in D mode the auto start-stop system turns the motor off at the red light and then turns the motor on and starts the car by brake release ?
Could you explain how the auto hold feature works? Is the clutch engaged as your foot is off the break when stopped? Great video and explanation. Thanks
Yes, I've been wondering about this too. We tend to use this a lot as it's an handy feature but it's our first Auto and I'm not sure if it's a good idea to use it too much. I'm sure it's all programmed into some kind of control system and I'm assuming because it's technically holding the brake for you the clutch is disengaged but is it and how close is it to bite point? It must be close because it goes pretty much as soon as the accelerator is pressed so is this causing wear to the clutch system?
Interesting! My Skoda Fabia DSG7 is currently in the workshop for clutch change. Have you noticed any difference in clutch pressure depending on how hard you press the brake when stationary? I feel that the revs drop and possibly the engine shuts down to save the environment when you press the brake hard. If I step loosely on the brake, it feels like the clutch pulls a little. Maybe that's why my clutch needs to be replaced after 6400 mil. I didn't think about this as the car was new and usually had very little brake pressure so that the engine wouldn't shut down.
Great video thank you. Would like to see the actual gear selection next to the torque data…simply because my low band brain needs just a little easier visual to calculate what’s going on
when you see the power go from one clutch to the next, a gear shift happened. its not easy to tell which way the gear change is since in a dual clutch the first clutch handles all odd gears and 2nd clutch handles all even gears, making it directionless unless you know the gear numbers. that sudden rise in current and pressure that you see in the other clutch before a shift is likely the other clutch getting ready to engage and "catch" from the current clutch.
It seems the clutch pressure increases with torque. In a manual the clutch is always applying the same pressure on the flywheel when you're off the pedal, if I understood it correctly. Interesting
The dsg compares the rotation speed of the shafts and if they are slipping it increases the pressure until there's no slippage. That happens in milliseconds.
thanks a lot, one is never to old to learn, in my case anyway.very good explanation of how everything works. Maybe you can help me with the following DSG question, is it possible to rev match a DSG in downshifting with the shifters of course. Pardon my english ,I am Dutch so.....
It rev matches every time I downshift whether using the paddles or the shift lever manually or if it auto downshifts. The fast I stop (harder I brake) the sooner it downshifts and rev matches.
I guess it matters what type of DSG you have. If it is with dry or wet clutch pack. For the dry clutch unit, if you go to neutral, at a stop light, you are going to save one of the pressure bearings in the clutch unit, not applying pressure for a long time, to keeping the engine decupled from the gearbox. For the one with wet clutch system, my thinking is that it doesn't matter what you do at stop. I think it is only applying pressure on the clutch pack when the car is moving. But I'm not very familiar with this type of gearbox. (This is just a logical assumption)
So it seems to me there is a difference between manual and drive/sport modes. In drive/sport, the clutch not engaed prepares fro the next shift by building some positive pressure. In manual mode this does not happen beause it cannot anticipate when you will shift and in which direction. So manual shifts feel different when you're driving around in manual mode. Am I right?
(Idont think it was that made said comment) but I did trully believe that sport mode was burning the clutches at a stop. I thought it left them half enaged due too the higher rpms and more importsntly the much faster engagement upon brake release... compared to normal drive which has a huge delay upon release until engagement the sportmode engagement feels instantaneaous(like it was already engaged). I now can tell i was clearly wrong and im actrually really happy i was because ive found normal drive too be super rough in first gear but its much smoother in sport mode(for multiple reasons ie-faster engagment better acceleration/smoother shift into second gear above light acceleration). Awsome:i shall now leave my car permanently in sport mode... okay this leads me too believe that leaving the differential in sport mode is also not bad??
I never concerned myself with the DSG, I'm just a car goes point A-B person. But I watched anyway, All this was so interesting because I'm a Data kind of guy. Thank you for making this video!
I knew putting the transmission in neutral would do something. If I have the foot brake applied, transmission in drive then rev the engine it does not sound and feel as smooth as if I put the transmission in neutral. Maybe this is done to help mimick a power launch in a real automatic transmission. Rev the engine and when you feel some resistance let go of the brake and fully dump the accelerator pedal.
Think of it as if you are driving a manual car. Will you depress the clutch and leave the gearbox in 1st gear all the way till the traffic light turns green? Technically speaking for DSG, when you shift to neutral, the solenoids will 'rest'.
What's the little circle within the rev needle on the digital cluster that moves with it? Does it flash when you hit redline or anything? Also how much of a pain was it coding the speed limit sign recognition to work?
Ok so what doing fuel consumtion (evonomy) difference? when you stop and on Drive mode and foot on brake pedal and fuel consumption is 0.7 l/h and same you stop but put transmision on Neutral and there is fuel consuption 0.6 l/h. How you explain that?
Really enjoying your technical content very well done!! Just wanted to ask about your open IE intake set up with the Do88 intercooler. I've just purchased the Do88 cooler and looking for a nice intake and considering the IE one but worried high IATs of an open intake will rob me of power/performance. Do you think the cooler equals things out and keeps temps at a happy power making level?
It's funny you ask. I am actually looking into perhaps changing up the intake for that very reason. Even with the do88 I feel like my intake temps are a little on the high side. I'm looking for an enclosed solution that takes advantage of grabbing as much airflow as possible. I think the open design has been good enough... sounds great... but I want to FORCE more air in... not just let warm air sweep past and let the turbo suck in what it needs.
There was once where I put my car (having DSG trans) in M1 mode while I was stuck in a traffic jam, and was just crawling in M1, suddenly my gearbox high temp alert came on, and I had to park the car on the road side to let the gearbox cooldown. Question, is my putting of M1 gear while crawling the root cause of gearbox overheat?
For some reason when in M1 and letting the car role it over heats some kind of clutch module I can’t remember what’s it’s called it may not be an exact module but it’s something like that and it over heats
Great video, the question is, is it better to use “autohold” than putting it in N, or is putting it in N better for preventing wear & tear? Thank you for informative video.
I found out my Audi must go into neutral at a stop because of this lag it had after taking my foot of the brake to accelerate. That's the way DSG is designed. I did a reset with the OBDeleven and now it works with no delay, and you can change the engagement time with the OBDeleven also. If you don't have an OBDeleven for you Audi or VB, get one. There are so many changes you can do to your car.
i just got an obd11 last week and i was looking into the transmission tab (bc my clutch/trans has been slipping and been really rough with jolting ect). i saw some options in there about the clutch ect. do you know what i could try to change? i cant find any info on what they all do.
@@ShowTimeSchoweSorry, I believe it's under apps, then workshop, then look for adaptation. Or try under transmission. Like where codes would be stored. Not 100 percent, but there should be some vids on TH-cam for the procedure. Also you can send OBDeleven a question.
When stopped, why is the torque different between the two clutches if both are disengaged? If a clutch is disengaged, the torque will be zero. The zero point for torque seems to be -74 ft.lbs. When stationary clutch 1 increases torque from -74in.lbs to -9in.lbs. How does it do that if the clutch is disengaged? BTW negative torque makes no sense unless there is a change in direction of the applied torque. This video creates more questions than it answers.
Surely the whole point of sport mode is that you want it to set off faster so it would be fairly pointless if it was not good for it to sit at lights etc?
in sports mode at least does the gear changes faster so doesn't take long in take to the 3rd gear and 4th gear thing that in drive mode happens but with certain lag, that I noticed I have tried using the sports mode and just that I noticed in a Skoda Fabia now doesn't know if have the dry clutch dsg or the wet version of the DSG gearbox
@@megacap55 Yeah, my personal experience is that in sports mode an auto car will rev higher between shifts and so accelerate more between gear changes. Arguably auto does change quicker but then auto also has more gears to change to achieve the same high speed having maybe 7 or 8 gears (possibly more on some cars) instead of 6 so I would say it's smoother rather than quicker than someone good at manual changes. I drive both but not high power cars so maybe I don't see as much benefit from auto.
Great video! Really answer my curiosity about the clutch engagement in real time. I have another question! Very often we're told to drive a dsg differently as compared to an auto car, by not releasing brake to inch forward (it's like a half clutch effect in manual car) during traffic jams, but rather to ensure there is enough space in the front and apply gas so as ensure clutch is fully engaged when we move. Is there anyway we can prove this theory on how the clutch is half or fully engaged?
In his videos you see the clutch current on the two clutches that indicate how much they are engaged/disengaged. Current in mid ranges indicate how much half-clutching the car is doing at that point AFAIK.
the video proves, he does parking lot stop/go and hits over 6bar, then under acceleration he only hits 5.7bar -- the wear and tear on the DSG from "stopping" is actually stop/go/creeping. The video also shows his hypothesis was incorrect and that shifting to neutral DOES relieve pressure from the plates, but he played it off like he wasn't wrong.
My observation would be if you are in Drive and you are stop the pressure in the transmission is on clutch two and transmission has pressure on clutch one so when you need to go the transmission is ready, but this is my observation.
so what happens when you stuck in traffick and cant switch from n to d every 2 seconds to "avoid" the clutch to be worn ? also anyone else has their car jump when accelerating in cold weather ?
I am sorry if my question sounds stupid. Can i summarise the take away as at a stop light, it’s theoretically best to switch to neutral since it disengage everything, including all the minuscule torque and engagement of the clutch. While best practice, it is unnecessary. Is that right? I am buying a golf 7 next week and been researching on how to look after the gear box. Plenty of horror stories I have heard from gearbox that’s badly looked after. Thanks in advance.
True. I'm driving a 2019 Skoda Octavia vrs with a DQ381 DSG Gearbox. I did monitor the engine load via obdeleven when the gearbox is in neutral and in 1st gear. There is a bit of engine load when the gearbox is in 1st gear whilst waiting at a traffic light.

Yes, I've been wondering about this too. We tend to use this a lot as it's an handy feature but it's our first Auto and I'm not sure if it's a good idea to use it too much. I'm sure it's all programmed into some kind of control system and I'm assuming because it's technically holding the brake for you the clutch is disengaged but is it and how close is it to bite point? It must be close because it goes pretty much as soon as the accelerator is pressed so is this causing wear to the clutch system?
Interesting! My Skoda Fabia DSG7 is currently in the workshop for clutch change. Have you noticed any difference in clutch pressure depending on how hard you press the brake when stationary? I feel that the revs drop and possibly the engine shuts down to save the environment when you press the brake hard. If I step loosely on the brake, it feels like the clutch pulls a little. Maybe that's why my clutch needs to be replaced after 6400 mil. I didn't think about this as the car was new and usually had very little brake pressure so that the engine wouldn't shut down.
Great video thank you.
Would like to see the actual gear selection next to the torque data…simply because my low band brain needs just a little easier visual to calculate what’s going on
when you see the power go from one clutch to the next, a gear shift happened. its not easy to tell which way the gear change is since in a dual clutch the first clutch handles all odd gears and 2nd clutch handles all even gears, making it directionless unless you know the gear numbers. that sudden rise in current and pressure that you see in the other clutch before a shift is likely the other clutch getting ready to engage and "catch" from the current clutch.
It seems the clutch pressure increases with torque. In a manual the clutch is always applying the same pressure on the flywheel when you're off the pedal, if I understood it correctly. Interesting
The dsg compares the rotation speed of the shafts and if they are slipping it increases the pressure until there's no slippage. That happens in milliseconds.
thanks a lot, one is never to old to learn, in my case anyway.very good explanation of how everything works. Maybe you can help me with the following DSG question, is it possible to rev match a DSG in downshifting with the shifters of course. Pardon my english ,I am Dutch so.....
It rev matches every time I downshift whether using the paddles or the shift lever manually or if it auto downshifts. The fast I stop (harder I brake) the sooner it downshifts and rev matches.
I guess it matters what type of DSG you have. If it is with dry or wet clutch pack. For the dry clutch unit, if you go to neutral, at a stop light, you are going to save one of the pressure bearings in the clutch unit, not applying pressure for a long time, to keeping the engine decupled from the gearbox. For the one with wet clutch system, my thinking is that it doesn't matter what you do at stop. I think it is only applying pressure on the clutch pack when the car is moving. But I'm not very familiar with this type of gearbox. (This is just a logical assumption)
that was a nice experiment it shows a lot of interesting info. many thanks and greeting from Egypt
So it seems to me there is a difference between manual and drive/sport modes. In drive/sport, the clutch not engaed prepares fro the next shift by building some positive pressure. In manual mode this does not happen beause it cannot anticipate when you will shift and in which direction. So manual shifts feel different when you're driving around in manual mode.
Am I right?
(Idont think it was that made said comment) but I did trully believe that sport mode was burning the clutches at a stop. I thought it left them half enaged due too the higher rpms and more importsntly the much faster engagement upon brake release... compared to normal drive which has a huge delay upon release until engagement the sportmode engagement feels instantaneaous(like it was already engaged). I now can tell i was clearly wrong and im actrually really happy i was because ive found normal drive too be super rough in first gear but its much smoother in sport mode(for multiple reasons ie-faster engagment better acceleration/smoother shift into second gear above light acceleration). Awsome:i shall now leave my car permanently in sport mode... okay this leads me too believe that leaving the differential in sport mode is also not bad??
But sports mode uses more gas
A question, im in manual mode and Approaching the traffic light, do i need to shift back or just let her shift back to first gear? 😁
@@attilaszabo1215 either is fine
@@EVERYTHINGcpo Great thanks!
I never concerned myself with the DSG, I'm just a car goes point A-B person. But I watched anyway, All this was so interesting because I'm a Data kind of guy.
Thank you for making this video!
I knew putting the transmission in neutral would do something. If I have the foot brake applied, transmission in drive then rev the engine it does not sound and feel as smooth as if I put the transmission in neutral. Maybe this is done to help mimick a power launch in a real automatic transmission. Rev the engine and when you feel some resistance let go of the brake and fully dump the accelerator pedal.
So should we switch to Neutral in Red traffic signals, so that the gear will be totally disengaged and will get more life for DSG ?
Think of it as if you are driving a manual car. Will you depress the clutch and leave the gearbox in 1st gear all the way till the traffic light turns green? Technically speaking for DSG, when you shift to neutral, the solenoids will 'rest'.
What is regulaiting the clutch preassures? Thought it is spring loaded?
Awesome video... Just wondering what happens when it's in P or R
What will be the status of the clutch when cruising on a highway ? At a constant speed and in the top most gear ?
Wondering this! Thank you for clarifying.
nice, were i can buy the dongle?
What's the little circle within the rev needle on the digital cluster that moves with it? Does it flash when you hit redline or anything? Also how much of a pain was it coding the speed limit sign recognition to work?
Ok so what doing fuel consumtion (evonomy) difference? when you stop and on Drive mode and foot on brake pedal and fuel consumption is 0.7 l/h and same you stop but put transmision on Neutral and there is fuel consuption 0.6 l/h. How you explain that?
Really enjoying your technical content very well done!! Just wanted to ask about your open IE intake set up with the Do88 intercooler. I've just purchased the Do88 cooler and looking for a nice intake and considering the IE one but worried high IATs of an open intake will rob me of power/performance. Do you think the cooler equals things out and keeps temps at a happy power making level?
It's funny you ask. I am actually looking into perhaps changing up the intake for that very reason. Even with the do88 I feel like my intake temps are a little on the high side. I'm looking for an enclosed solution that takes advantage of grabbing as much airflow as possible. I think the open design has been good enough... sounds great... but I want to FORCE more air in... not just let warm air sweep past and let the turbo suck in what it needs.
@@EVERYTHINGcpo cool keen to see what intake you go for. Will probably just do the intake mod on the OEM intake for the time being. Cheers
@@EVERYTHINGcpo i also want to take do88 and mst performance intake & inlet i should pass my dsg6 to stage one?* or stock is fine?
I use sport mode to be obnoxious because it stays in 4th for ages which makes my exhaust obnoxiously loud hahaha
lol!
im always in sport manual, rather it stay in the gear i want, im very rarely in auto
hello there, this is a really interesting video/information. what is the app on your tablet? Thank you.
There was once where I put my car (having DSG trans) in M1 mode while I was stuck in a traffic jam, and was just crawling in M1, suddenly my gearbox high temp alert came on, and I had to park the car on the road side to let the gearbox cooldown. Question, is my putting of M1 gear while crawling the root cause of gearbox overheat?
For some reason when in M1 and letting the car role it over heats some kind of clutch module I can’t remember what’s it’s called it may not be an exact module but it’s something like that and it over heats
What is the maximum clutch pressure after tuned?
Is there a different comparing to stock calibration?
Please, can anyone tell me why the torch remains at -9
Great video, the question is, is it better to use “autohold” than putting it in N, or is putting it in N better for preventing wear & tear? Thank you for informative video.
I found out my Audi must go into neutral at a stop because of this lag it had after taking my foot of the brake to accelerate. That's the way DSG is designed. I did a reset with the OBDeleven and now it works with no delay, and you can change the engagement time with the OBDeleven also. If you don't have an OBDeleven for you Audi or VB, get one. There are so many changes you can do to your car.
how do you change engagement time with OBD?
i just got an obd11 last week and i was looking into the transmission tab (bc my clutch/trans has been slipping and been really rough with jolting ect). i saw some options in there about the clutch ect. do you know what i could try to change? i cant find any info on what they all do.
@@ShowTimeSchoweSorry, I believe it's under apps, then workshop, then look for adaptation. Or try under transmission. Like where codes would be stored. Not 100 percent, but there should be some vids on TH-cam for the procedure. Also you can send OBDeleven a question.
When stopped, why is the torque different between the two clutches if both are disengaged? If a clutch is disengaged, the torque will be zero.
The zero point for torque seems to be -74 ft.lbs. When stationary clutch 1 increases torque from -74in.lbs to -9in.lbs. How does it do that if the clutch is disengaged?
BTW negative torque makes no sense unless there is a change in direction of the applied torque.
This video creates more questions than it answers.
So if I get it right the best way to keep your clutches for a long time is to put on N while waiting ?
Thanks for sharing
No, has no effect on clutch life.
Surely the whole point of sport mode is that you want it to set off faster so it would be fairly pointless if it was not good for it to sit at lights etc?
in sports mode at least does the gear changes faster so doesn't take long in take to the 3rd gear and 4th gear thing that in drive mode happens but with certain lag, that I noticed I have tried using the sports mode and just that I noticed in a Skoda Fabia now doesn't know if have the dry clutch dsg or the wet version of the DSG gearbox
@@megacap55 Yeah, my personal experience is that in sports mode an auto car will rev higher between shifts and so accelerate more between gear changes. Arguably auto does change quicker but then auto also has more gears to change to achieve the same high speed having maybe 7 or 8 gears (possibly more on some cars) instead of 6 so I would say it's smoother rather than quicker than someone good at manual changes. I drive both but not high power cars so maybe I don't see as much benefit from auto.
I drove my S3 2015 only in dynamic mode. No issues with the dsg and I had it for 9 years 100k miles.
From my opinion Manual mode or S mode are absolutely good to use DSG
There is an article called DSG SOP 5.0 which I can learn how to properly use DSG
Great video! Really answer my curiosity about the clutch engagement in real time.
I have another question! Very often we're told to drive a dsg differently as compared to an auto car, by not releasing brake to inch forward (it's like a half clutch effect in manual car) during traffic jams, but rather to ensure there is enough space in the front and apply gas so as ensure clutch is fully engaged when we move.
Is there anyway we can prove this theory on how the clutch is half or fully engaged?
In his videos you see the clutch current on the two clutches that indicate how much they are engaged/disengaged. Current in mid ranges indicate how much half-clutching the car is doing at that point AFAIK.
the video proves, he does parking lot stop/go and hits over 6bar, then under acceleration he only hits 5.7bar -- the wear and tear on the DSG from "stopping" is actually stop/go/creeping. The video also shows his hypothesis was incorrect and that shifting to neutral DOES relieve pressure from the plates, but he played it off like he wasn't wrong.
what happens if you rev it in netural or park i wanna see the results and if its damgaing your transmatition
Hello Brother, I need to know what oil you are you use?
Came here after worrying forum posts about DSG, thanks. I guess I will be fine as a slow-paced defensive driver.
What if we put in park mode
when in in heavy traffic i use manual mode or S also and use N at stop, i also even feel shencsr just sliping, its like manual car
Very interesting and nice video, for me too much time in a redlight neutral, i dont like the pressure you make too your brakes.
Does the parking, hand brake have any effect?
My observation would be if you are in Drive and you are stop the pressure in the transmission is on clutch two and transmission has pressure on clutch one so when you need to go the transmission is ready, but this is my observation.
This is a great and very well detailed video.
Excellent video, very informative 👍👍
Great explanation! 🤙🏼
What milage intervals do you change the dsg fluid? Does the milage change when tuned and modded? And how hot is too hot for dsg fluid?
Every 40k but if you race it a lot, you should do it more often. Checking fluid level at 95F-113F. There are plenty of DIYs on-line.
VW says every 40k. Tuned I'd go with 20-30k tbh. Especially with high torque tunes.
Wow
Very nice and informative video ever about DSG.
THANKS MAN.
Does this apply to DQ200 dry clutch gearbox too?
But why is the rpm going up and where does the vibration come from when stopping in D/S? The video only answer half of the question😆
so what happens when you stuck in traffick and cant switch from n to d every 2 seconds to "avoid" the clutch to be worn ? also anyone else has their car jump when accelerating in cold weather ?
be reasonable, even with a manual foot pedal clutch, 2 seconds, most people would just hold down the clutch pedal.
Thank you so much for this explanation!
any tutorial for setup up this?
Nice
I drive in manual all the time
Most of the time in the city so firs and second gear will not change so often back and forth all the time
I am sorry if my question sounds stupid.
Can i summarise the take away as at a stop light, it’s theoretically best to switch to neutral since it disengage everything, including all the minuscule torque and engagement of the clutch. While best practice, it is unnecessary.
Is that right?
I am buying a golf 7 next week and been researching on how to look after the gear box. Plenty of horror stories I have heard from gearbox that’s badly looked after.
Thanks in advance.
True. I'm driving a 2019 Skoda Octavia vrs with a DQ381 DSG Gearbox. I did monitor the engine load via obdeleven when the gearbox is in neutral and in 1st gear. There is a bit of engine load when the gearbox is in 1st gear whilst waiting at a traffic light.
Brilliant video! Thanks 🙏🏻
