It always amazes me that for decades things have worked perfectly, then comes along some bright spark who decides to make something simple more complicated, and in the process bring complexity and problems to something that has always worked fine?
My thoughts exactly. I am still not convinced it is actually helpful or intentionally creating more service needs. I am not a mechanic therefore did a little digging and still don't understand why we actually need this "improvement". The argument I found was that modern cars are more powerful and normal clutch can't handle that. Errmm... My son has a 1.4l petrol engine with DMF... I am pretty sure that my 1.6i sports car was way more powerful 20 odd years ago and that had regular flywheel. I just knew how to use the clutch? Confused...
@@Cheepchipsable Common rail Diesels = big torque spikes. Traditional spring damped clutch plates (people like to forget this) no longer provide enough damping.
Try driving a diesel that has several hundred pounds of feet of torque below 2000rpm and can pull a 36mph per 1000rpm 6th gear from as low as 1200rpm. The dual mass absorbs the movement that occurs each time a cylinder fires at very low rpm. This movement would bottom out a standard clutches springs straight away or they would need to be stiff enough that the gearbox would have to absorb the pulses instead. As engine speed increases this disappears. If you only drive over 2000rpm or so you can get away without one but surely that defeats the point of buying a very modern Diesel engine with all that low end in the first place.
But its not that simple is it, put a SMF on a modern diesel, good luck driving that bitch at less than 1500 rpm, cos it will judder like a male dog smelling an in heat bitch. It smothes out the power strokes and there worth there weight in gold. The piss take with them is they could easily be made to last the life of the car, and you can get aftermarket jobs that will do the life of the car, my A3 has 220,000 miles on the clock (BKD) and the flywheel is now on its forth clutch and still rock solid, yes, it cost me more than a grand to buy, but there £300 each for OEM ones and HAVE to be done with the clutch, so its £1000 for OEM, every 50,000 miles or so, or £1000 upfront, and £200 clutches every 50,000 miles. Had the same on my Focus CMAX DM02, 350,000 miles before it went to scrap, DMF had more clutches than a hooker does clients on a friday night in soho.
One of the main reasons a DMF is there is to absorb vibration and kick from the engine before it gets to the transmission. DMFs provide a dampener for your transmission and enable manufacturers to produce lighter and less robust transmissions. That translates to cheaper lighter and weaker. Fitting a SM flywheel is more likely to knock out a bearing or damage another transmission component rather than damage the engine
No it's completely wrong! I used to be a plant manager of the company that invented them (luk) and I guarantee this is wrong! The dual mass fly wheel is a torsional damper.
Same😢 @humblemechanic I know this vid is like half a decade old lol, but maybe you could shed some light on replacing the DMF with a SMF in DSG MK6 Golf R?
My old dmf started squeaking and cherping at idle thought a family of birds where nesting in the bell housing it would make a rattle when the clutch was half down, eventually it rattled all the time, wasn't really that worn when I took it out, but loose enough to rattle, they are an awful design and designed to fleece the customer even more never hear anything good about dmfs designed by dickhead, I changed it to single mass flywheel conversion.
I actually ended paying the mechanic a total of aprox 3500$(in Norway) for replacing clutch + dmf. I was thinking of getting a smf but was warned against it and they then told me that the vibrations in a smf would wear out the transmission/gearbox way faster, do you know if this is true? Great video btw, keep up the good work.
My nissan almera 2.2 diesel DMF went after 40000 miles!! replaced with SMF 24 years later and nearly 300000 miles on the clock slightly more rattley not one fault and still going strong and my wallet is bigger!!
I've just replaced the DMF and clutch on my 2008 Golf Mk5 TDI. My clue that there was a problem was a rattling/grinding noise at idle - not as bad as in HM's video, but definitely there; it sounded like it was coming from somewhere deep in the engine bay, and it went away when you pressed the clutch pedal. I used a mechanic's stethoscope to confirm it was coming from the transmission. It's a pretty straightforward job to replace it, it's mainly just time-consuming, although I was completely unprepared for how heavy the transmission was and while I was able to use gravity to get it out, it was impossible for me to bench-press it back in while laying on my back. I had to call a mobile clutch guy just to wrestle the box back in for me. FWIW, from the point of originally noticing the noise to actually fixing it took over a year. The car is my daily and drove just fine in that time. When I got the old DMF out, it wasn't *that* loose; I was expecting it to be in a much worse state than it was.
Great explanation of the VW DMF failure. I had signs of DMF problems in my MK1 Seat Leon ASZ 1.9TDI (MK4 Golf), it started with a grinding feeling when the clutch plate engaged, but also a 'chattering' noise at the point of flywheel to clutch engagement. Ended up fitting a stronger clutch plate and single mass flywheel, it was well worth doing. Yes there was increased noise and vibration at lower revs, but not something you would notice unless looking for it, none of my passengers ever questioned the noise. Changing the clutch and flywheel took around 6 hours on a gravel driveway with a pair of axle stands and trolley jack. Certainly a DIY job for those with time and basic tools. (And the willingness to give it a go). That car has been scrapped now, but it did 202000 miles whilst the body and subframe deteriorated around it. In the end I had to get rid of it because getting it through an MOT here in the UK was going to cost too much in parts alone for a tatty car. The engine and gearbox.... Not started in 4 months yet cranked strongly straight away when someone came to take it off me. Thankfully the engine and possibly gearbox live on inside someone's MK4 Golf 😁
Had a severe failure on an ARL Seat Leon 1.9. Rattle on shutdown. Ran fine for a minute, then noticed the gearstick violently shaking back and forth and the vehicle making extremely unusual sounds as it tried to shake itself apart. I found multiple hot spots on the dual mass. That much play I'm surprised it was still in one piece. And finally, a hole in the bottom of it with something poking out. Surprisingly there was no damage to anything on the engine or the gearbox
Great vid! I have an '03 GTI VR6 with almost 150K miles on it, that has been vibrating a lot lately, and not shifting crisply/smoothly. It was just diagnosed with a damaged DMF and probably worn clutch. It amazes me that after 22 years of ownership as my daily driver, that the DMF and clutch lasted this long! Yes, the car has been garaged & 'babied' all these years, and maintained well, and driven normally (rarely aggressively). I've never changed the 6-speed manual transmission oil though. So even though i've had 22 year old oil in the gearbox, the transmission has held up nicely. Anyway, a local well respected garage that specialized in Euro cars, especially German, quoted me $1950 for the job, and they're putting in a SMF. The engine is perfect, so I could probably get another 10 to 20 years out of it, I figure!
I like SMF in a mk4… but I guess with the low end torque in a diesel a lot of people say the DMF. At the end of the day we out here trying to keep these ol baddies on the road as long as possible 😂
They say DMF protects transmission. On the other hand, second hand transmission is a lot of cheaper than a DMF. Just of curiosity, did you switch to SMF and how it performed?
I loved the video Charles! I have a MK4 2004 VW Jetta GLI 2.8L 24v VR6 6 speed Manual 02M. Planning to buy a South Bend Daily Stage 3. Do I need to buy a new Dual Mass Flywheel, or should I keep the one that came with my car as OEM? I think mine is DMF LuK 240mm. Should I buy a brand new DMF from LuK that matches mine? Mine is almost 20 years old or should I switch to a Single Mass Flywheel? I hate to install a brand-new aftermarket Clutch of this caliber and keep the old DMF. If you recommend replacing the DUAL MASS FLYWHEEL, with a SMF brand model, will it go well on the MK4 platform for this car? Sorry for these type of rookie questions, I am pretty sure you get asked these all the time, my apologies, but someone told me that you are the MK4 expert in the whole east coast.
Had this happen on my last two VW-based cars, a SEAT Leon TDI (based on a Mk4 Golf) and a VW Sharan, the latter actually destroyed the whole gearbox. Both cars had over 100,000 miles on them. I replaced the SEAT's with a SMF and I really couldn't notice any difference in vibration. These days I drive an automatic Mercedes...
I hate those flywheels. I drive a Nissan Navara (Frontier) and about 50.000km ago the thing was replaced. Now it's back to the rattle in the can. This time I go for a SMF one. I'm sick of this cr.p.
Audi, VW, Same shit. I'd never touch one again.I'd way rather drive Japanese than German crap. Japanese way outlasts German crap with a fraction of the maintenance costs. I had a V6 Audi and while it was the nicest drive ever, it was also the most unreliable shit I ever owned and cost a bloody fortune to maintain. That's why they have no resale value.
And what about dmf for dsg? How can i upgrade it? I have a dsg tt 08 with k04 and flywheel die every track day... Sachs said that it only support 300 lbft. And my car have more than that. I already have tcu tune... maybe tcu problem or dmf are at the limit?
Could something like this occur from a catastrophic event, say driving through water or something that could lodge between the plates if the car floats for a short period of time?
in east Europe are some good shops that rebuild them (if the damage is not definitive) by resurfacing , balancing , replacing the springs, etc. this is not possible for all models , it depends of the spare parts , quite hard to find. the cost is around 180 $ / unit.
Hi there, great video. My vw T5 has just started rattling about a month ago. It has got progressively more noticeable. It’s definitely nowhere as bad as your example in the video. It mainly rattled when starting the car and accelerating/going over bumps in the road. Just wondering if you think the car is still safe to drive for much longer? I want to go on a trip this weekend, only 2 hour drive, but nervous about something going wrong. Thanks
Been searching for a few days on this problem, that's the exact same noise that has stated in my Passat b5 DSG, ive got a added squeel when deaccelerating, gave me certainty on what part to buy, thank you 👍
I bought my GTI new and the dual mass flywheel went out at 54K miles. I'm mechanically inclined and can fix most anything on a car. I skipped the warranty and replaced it with a one piece flywheel because I had intentions to do an APR flash. In the end, I decided against the APR flash as my car is plenty quick for me. I have 113K on my GTI on the original engine and the only other problem I had was the intake manifold needed replace. $170 for a new intake and I cleaned the intake valves while I was at it. My car has been great other than these two things.
Hey Charles, are the DMF failures more prevalent on the MK5 TDIs or the MK5 2.5 gas engines? I see tons of youtube failures on the TDIs only. I am suspecting this dual-flywheel wear stems from the TDIs low end torque coupled with spirited stop and go driving. I've never heard of a single mass flywheel failing BEFORE a clutch failing.
Hi, I'm waiting for the buyback of my TDI (Canada), my DMF started to make sounds 20 000 km (12 000 miles) ago and in the last month it started to slip when changing from 1st to 2nd. My question is: should I park the car and stop using it in case the DMF completely fails? Currently it's only when the car is cold, does it gives you any ideas on on worse it is ?
Lucas Côté had that problem myself and the dealer wont redo the work and wants another 1700 I should have got a solicitor but later on I changed it myself. Made to rip people off.
I've been driving manual transmission cars and trucks all my life (61' bug, 65' mustang, 59' chevy fleet side, and currently a 2014 taco) and always thought smooth engagement was up to the operator! Never had chatter problems or longevity issues. Sound like DM flywheels are another way to up the price of repairs to me. Really!
4 cylinder diesels in audis like 1.9tdi vibrate quite a bit, it is good having a dual mass. I had two 1.9tdi’s one with dual mass and one without it Imo worth it Although a lighter flywheel would be better for perfomance
One of the reasons for dual mass 'technology' is to prevent deterioration of gearbox components, many of which are now plastic or composites..so the DMF is meant to help prevent those components from failures...However, as I contemplate the replacement of my DMF on my VW LT35 (not available in North America butt basically a Merc Sprinter) I also note the very expensive replacement kits, as mentioned by Charles. 'Stealerships' will charge well over 1500-00 Pounds for replacement, including parts...You can easily find LT35's for sale or being stripped because these parts make them uneconomic to repair..Shame really, they are decent vans.
not every operator is going to super smooth with the gear changes the dmf also increases transmission life and is cheaper to replace than a broken transmission. I have seen cars converted to SMF and the transmission went out after a few months
i have a b8 s4, my mechanic says its the DMF and to go to SMF but i dont hear any noise, i just have a hard time getting into 1st/2nd as i think the clutch isnt totally disengaging when the pedal is depressed.
My 07 Audi needs a clutch job, mechanic quoted $1900 CDN for the DMF. Found that LuK sells them for $650 CDN. Now just got 9 hours of labor to save for.
How come you can't get a DMF refurbished IF its only a few springs worn or damaged in side of it? I'm sure they wont cost a $1000. Its just an other way garages rip people off
You are epic! I’ve got a VW Passat 06 and have heard this noise for ages. I thought it was probably to do with the clutch as when I depress the clutch the noise goes away ta-dah. That video you play at 2:29 is the EXACT noise coming from under my engine. Now I know what the issue is I can do some research before going in blind to a mechanic. Thank you!!
Hello ! I have a volkswagen cc tdi DSG from 2013 and i have to change the flywheel but i was wondering if after the change my car will go smoother , the car is vibrating at lower Rpm like 1200 - 1400 rpm , will the change of the flywheel resolve this problem also ? If u're reading and answering this Thankyou Verry Much ! :D
Get that beard trimmed,it scares me being a being a beardie.! you would not be allowed into any workshop,especially drills/grinders/things revolving etc.. etc..they would tear you face off..!!
Hello, can you explain to me the Gds gearbox, the advantages and disadvantages, and how many kilos to change the oil, and is it the same as the normal gear, why some cars when the brakes are worn out, and some when the brakes are worn out? Thank you, engineer.
I had this seize up on my Subaru XV crosstrek after only 60,000 Km. Thought the clutch was bad. Turns out it died and killed my clutch so I had to shell out 2,000€ to replace both. Mine didn't make any noise at all. Just started smelling clutch burn.
Kermit the Frog Useful comment , thanks . The exact same symptoms on my 2.5 Focus at 39.000 miles. No noise but burning smell and slight vibration on low revs.
Hey Humblemechanic I would like to pose a question. I had my clutch disc go qt 17k on my 2013 tdi. They knew it was a bad disc and stated they would replace with upgraded part. However I was able to see the part they took out it had holes all around within the friction material and the other side the friction material separated. I had asked them to replace the DMF as well so as not to have to come back but they left the DMF. I was not really happy at all. IT has been 20k now and the clutch is exhibiting similar signs again. Why would the tech not replace the DMF at this time to avoid further issues.
gsleve That is a good questions with a lot of different possibilities. I sure as hell would replace the DMF. IT may be due to warranty costs at the dealer being high, it could be laziness, it may be that he just didn't know any better. I think I will push this to a Q&A show if that is cool with you? I find it very interesting.
Great video! I got a brand new DMF sent but uppon inspection it has some broken chips on the outside circunference of the face, not the teeth ring. Nothing seems to be lose inside nor funny noises. Do you think I should send it back? Thanks
I have exactly the same noise coming from under the hood... but it's an automatic transmission on a 2006 jetta tdi... Does it also have a flywheel? Didn't think so, so what else could it be? Thanks for any suggestions...
I was changing oil in my friends turbo diesel 2006 Jetta, and heard the dreaded Rattle. She had 80K on the car. Volkswagen would not warranty it, so she sold it on Craigslist. When I researched the issue, I found it was a common problem, esp. for that year. I'm a heavy diesel tech., and early Ford powerstep kestrel had the same problem. I lost all respect for Volkswagen after that.
I have a rattle on my 15 Jetta TDI DSG. It’s sporadically rattles even with the belt off this eliminating ac and alternator. Does the DSG auto have a DMF? Car has 223000 miles fuel economy still 50 + mpg.
I have a 2016 Skoda octavia, 115000km on clock. I get intermittent rumbling when I start to accelerate from a stop. more so if i accelerate heavily.some people I have spoken to have said that it is DMF issue. Others have said that it needs a clutch kit. Not sure what it's more likely to be? Do both need replacing? Car drives perfect otherwise. Any ideas?
Hello Humble mechanic. Please help I have a 2011 vw caddy maxi 7speed DSG. I’ve had three gearboxes, clutch packs and mechatronic units but now I’ve got the death rattle coming from I think the flywheel. Is there anything I need to be checking or will it be yet another 5k bill ? Thank you
Would you or do you have any videos with a single mass flywheel commentary or review? id love to see you review the Valeo SMF kit for the 02M mk4... 6spd...
Hi Humble Mechanic! I'm in the middle of converting auto to manual in my vanagon camper.. I have an 01 VW Jetta, TDI engine, and was running auto, but am going manual tranny, because I can install the LSD, and a locker option, while staying 2wd. :) Is there a best technology/brand to use for DMF on this engine? Would you choose to run a TDI on a SMF? I was looking on a AUDI TV channel video describing the advances in a design called "Dual-mass flywheel with centrifugal pendulum absorber". The video is at th-cam.com/video/YRxrajJCLr0/w-d-xo.html for reference. I am unclear if the LUK/Sachs or other brands use this technology in the DMFs.. I actually emailed Thanks! I love your videos!!!!!
149,000 miles on my '06 Ibiza 1.9 PD and the DMF has just started to knock. They can last a decent amount of time if you drive the car in a certain way, ie. not lugging the engine at low RPMs, not holding the car on an incline with the clutch instead of the brakes, not dropping the clutch hard and not pulling away without bringing the revs above ~1100-1200RPM
It’s a good explanation! A lot of shops will say it’s a bad bearing if they don’t know much about dual mass flywheels and they suggest replacing the whole trans! When I’m reality, it’s just a dmf.
Hi Charles, I have a rattling/vibration coming from my clutch system when in neutral but when I push the clutch pedal down just a half inch it goes away. Is this a bad throwout bearing?
HumbleMechanic the car is the "newer" 1.9 tdi bls with dpf and known for weaker conrods and crankshaft.the car was very wobbly from the dmf and after 7h of driving and 700km the engine started to knock .
I bought a 2009 TDI CBEA common rail with what sounded off like bad lifters. You know, that clacking noise..... Ordered from Latvia, replaced them suckers, put all back together to find out that clacking noise was still there. F....CK... Should have realized this was piston slapping from the beginning. Any tips or advice how to differentiate between these two? Think that will help a lot of us out there to keep from replacing what is otherwise fine and determine the real cause of the problem - this kind of problem at least. Thanks a lot love you videos for their simplicity and down to earth language.
My flywheel isn't making that noise but I think it's warped because my car trembles A LOT when engaging the clutch from a stand still, and it does not have much momentum so I have to accelerate. Can I just swap out my DMF for a solid flywheel or will my clutch not be compatible with it? I have a 2016 3.7L V6 Mustang and I don't have the money right now for a DMF replacement 😔
Hey can anyone recommend or tell me what I should also replace while I’m putting a new DMF on 2011 Volkswagen Jetta tdi with 6speed automatic DSG? Thanks so much for anything helpful!!
I have a 2013 Skoda Octavia RS 2.0 TDI 6sp DSG making the dual fly wheel failure sound, it only happens when the cars in park and engine is cold. Should I be worried about this? And if I want to get it fixed, I can swap it over for a single fly wheel?
I have to have mine done - diagnosed today - yes, very expensive job! You just mentioned a manual transmission, but this is a VW Passat with auto 6-spd wet clutch DSG. Is it essentially the same set-up?
Do you have a video of a CVT 7 speed flywheel I think my has gone but not 100% was going 70 mph and can't pulled me to a stop will drive but as soon as I put 2000 MRP on it starts to judder?
Exactly if you don't take care about the first simpthoms like vibrations after replace the dual mass flywheel by the cheap one (single mass) that's it will be whole transmission &transaxle assembly and the rear differential damage, I know it by own experience...
Just had my vw crafter done £1400 not cheap I would have done it myself but no ramp 😭 I was looking at fitting a solid state flywheel but was advised it can cause gearbox problems
I have an high-pitched noise in my GTI Mk6, exactly as in this video: th-cam.com/video/tcVwmub1Uzs/w-d-xo.html Is the TO bearing or the flywheel? Thanks for the help.
...flywheel biting the dust..and I just paid for timing job....why can't this stupid car spread the expenses out apart idk myabe wait 6 months not like 4 days and decided well either the engine is toast. Oh wait it's actually the dsg flywheel going out.
Hello. Sorry to bought you with this , but my way to inform myself is a little obstruct by the information I can't find or I am to stupid to find . I have a vw cady 1.6 dsg and last year the problems start with this car . First the megatronic unit brok and because I didn't have enough money to go to vw I used local mechanics how didn't know very good about the problem. This year the head gasket below up on 120000 miles and I repeat it with Steel Seal but still have a lick somewhere , probably is the water pump, and with the water pump I have changed the belts to. So my problem is, can I put a 2.0 litre motor with a different gearbox in the place of a 1.6 litres.?
Care to do a single vs dual mass flyweel on the same car, ex. VW to see whats the difference. Im thinking to switch to regular flyweel but I dont know how much vibrations is really.
Please Help, My ford focus has a dual mass fly wheel has over 160,000 miles on it I just installed a new clutch kit in July due to the clutch pedal falling on the floor & the ability change gear. I installed a new clutch kit but after 2 months of driving after the clutch pedal started to fall to floor and pulling the clutch pedal back up stop working. I replaced the master cylinder twice because I lacked the ability to build clutch pressure. I went to a transmission shop and was told to the clutch slave cylinder was the cause and was leaking. I replaced the clutch slave cylinder and was able to successfully bleed the air, build pressure and to get the clutch pedal was hard like it is supposed to happen. Upon engine start up the clutch pedal fell to the floor and would not rebound. I did notice that brake fluid was coming from the transmission. I contacted tech support and was told the slave cylinder over extended and busted at start-up of the engine. I was told by the tech support from the Master Cylinder manufacture to replace the DMFW because that was the cause of the slave cylinder over extension. I called the manufacture of the clutch kit and they felt the DMFW is working find and the pressure plate was the cause and to get a new clutch kit and to install it. So far I have not noticed any odd vibrations and unusually noises. I did notice with the fly still installed on the car and the pressure plate uninstalled that when I push on the edges of the flywheel it tilts a little. I am not sure if it is considered normal and should i just replace the fly wheel anyway. I do not want to put my car together for 3rd time and to have the slave cylinder to fail for a 3rd time but i can't afford to just purchase a new fly wheel just because. Is there a test can preform on the fly wheel to verify if it is bad or not. What do you suggest.
There's also, of course, the advantage of weight and resulting increase of moment of inertia, although that's probably not a big enough advantage compared to the NVH increase for a daily driver.
***** Agreed, I wouldn't go so far as to say lightened flywheels unless it's a track car but if mine broke I'd definitely go SMF especially for fast road use, comfort is not something I care about most in my cars, within reason of course. maybe when I'm old... but by then everybody will probably have EVs anyway and definitely no manuals :s.
I have an 05 Audi A4 2.0, manual and my car was towed and they put it into nutrual somehow and now my car has a mean vibration and it's like my clutch is engaged all the time. My car revs high when driving it like I am riding the clutch. Any advice?
So why has mine gone bad? Makes no noise and only notice it at idle, sometimes you don’t know anything’s wrong but sometimes the engine shakes like f***, until you put strain on the flywheel then it stops shaking 🤷🏻♂️🤨
Hello...i need your help..if you can give me some advice I would appreciate it a lot. th-cam.com/video/yPQKXYERb2I/w-d-xo.html Do you know is its a flywheel issue or something else? It makes this noise when I press the clutch. I can hear it in first gear and in reverse. Car is a hyundai tucson awd diesel hybrid.
Well.... Fuck. That video at 2:20? That sounds a bit like my car. Maybe not with the same intensity, but it's getting there. Guess what i need to buy next.
Do they ever fail without warning? Was driving up a hill with no issues or noises and on the down side I put it in neutral to coast down the other side. A bit down the road input it into 5th and let the clutch out and the engine revved like it was in neutral still. Tried 4th and 3rd no go..... Pulled off and stopped the car, it felt like it would go into gear, but nothing when I let the clutch out.....
My 2012 GTi wouldn't go into gear one night. Turns out the clutch failed. With only 47K miles on it!! I find this rather shocking as my previous car was an '04 Golf TDi with 148K miles at trade in for this car.......it was on the OEM clutch still. I can drive rather fast at times and tend to downshift all the time. But still it isn't like I'm riding the thing or not matching RPM. But FFS 47K miles?!? So, the OEM parts were some $1400.....said nuts to that....had them install a stage 2 kit with Teflon. Hopefully this one will last a bit longer! Thanks for the video man! I'm going to watch the rest of your VW series for sure!
Hay HumbleMechanic, You didn't explain why the DMF in your video has the center cut out. I don't want to get into if the dealer classifies this as a defect, but would you? How many other main drive train parts have to be cut out upon failure? TDI love from Chicago
The over consensus I'm getting from every mechanic who has posted a video about these dual mass flywheels is that they're junk. I've driven vehicles with both dual and single mass flywheels and frankly I don't see any advantage to the dual mass system, (or at least not to the point where I could ever justify replacing one with the same part). If I ever have to do a clutch job on a vehicle that has one, it's getting swapped out for a traditional flywheel.
+Rangerman9404 I like the way that DMF drive. To me it has a slightly smoother engagement. Not life changing, but nice. That being said, I am probably going SMF when I put a clutch in the GTI
It always amazes me that for decades things have worked perfectly, then comes along some bright spark who decides to make something simple more complicated, and in the process bring complexity and problems to something that has always worked fine?
My thoughts exactly. I am still not convinced it is actually helpful or intentionally creating more service needs. I am not a mechanic therefore did a little digging and still don't understand why we actually need this "improvement". The argument I found was that modern cars are more powerful and normal clutch can't handle that. Errmm... My son has a 1.4l petrol engine with DMF... I am pretty sure that my 1.6i sports car was way more powerful 20 odd years ago and that had regular flywheel. I just knew how to use the clutch? Confused...
Apparently more do do with the uptake of diesel in the consumer car market.
The vibration thing seems to be more of a diesel problem.
@@Cheepchipsable Common rail Diesels = big torque spikes. Traditional spring damped clutch plates (people like to forget this) no longer provide enough damping.
Try driving a diesel that has several hundred pounds of feet of torque below 2000rpm and can pull a 36mph per 1000rpm 6th gear from as low as 1200rpm. The dual mass absorbs the movement that occurs each time a cylinder fires at very low rpm. This movement would bottom out a standard clutches springs straight away or they would need to be stiff enough that the gearbox would have to absorb the pulses instead. As engine speed increases this disappears. If you only drive over 2000rpm or so you can get away without one but surely that defeats the point of buying a very modern Diesel engine with all that low end in the first place.
But its not that simple is it, put a SMF on a modern diesel, good luck driving that bitch at less than 1500 rpm, cos it will judder like a male dog smelling an in heat bitch.
It smothes out the power strokes and there worth there weight in gold.
The piss take with them is they could easily be made to last the life of the car, and you can get aftermarket jobs that will do the life of the car, my A3 has 220,000 miles on the clock (BKD) and the flywheel is now on its forth clutch and still rock solid, yes, it cost me more than a grand to buy, but there £300 each for OEM ones and HAVE to be done with the clutch, so its £1000 for OEM, every 50,000 miles or so, or £1000 upfront, and £200 clutches every 50,000 miles.
Had the same on my Focus CMAX DM02, 350,000 miles before it went to scrap, DMF had more clutches than a hooker does clients on a friday night in soho.
One of the main reasons a DMF is there is to absorb vibration and kick from the engine before it gets to the transmission. DMFs provide a dampener for your transmission and enable manufacturers to produce lighter and less robust transmissions. That translates to cheaper lighter and weaker. Fitting a SM flywheel is more likely to knock out a bearing or damage another transmission component rather than damage the engine
One of the best explanations so far of a dual mass flywheel. Well done!
+JulianJunior Thank you
Yes, but talking a bit too fast.
No it's completely wrong! I used to be a plant manager of the company that invented them (luk) and I guarantee this is wrong! The dual mass fly wheel is a torsional damper.
@@stevemarks9360 lol now we know why you used to be one
My flywheel just did this ☹️
Oh no!!!!
Same
Think mine has too 🙄🤦🏻♂️😤
Common fault on the audi mine cost £630 to get fixed. Better than that noise though
Same😢 @humblemechanic I know this vid is like half a decade old lol, but maybe you could shed some light on replacing the DMF with a SMF in DSG MK6 Golf R?
My old dmf started squeaking and cherping at idle thought a family of birds where nesting in the bell housing it would make a rattle when the clutch was half down, eventually it rattled all the time, wasn't really that worn when I took it out, but loose enough to rattle, they are an awful design and designed to fleece the customer even more never hear anything good about dmfs designed by dickhead, I changed it to single mass flywheel conversion.
I actually ended paying the mechanic a total of aprox 3500$(in Norway) for replacing clutch + dmf. I was thinking of getting a smf but was warned against it and they then told me that the vibrations in a smf would wear out the transmission/gearbox way faster, do you know if this is true? Great video btw, keep up the good work.
Yes
My nissan almera 2.2 diesel DMF went after 40000 miles!! replaced with SMF 24 years later and nearly 300000 miles on the clock slightly more rattley not one fault and still going strong and my wallet is bigger!!
I've just replaced the DMF and clutch on my 2008 Golf Mk5 TDI. My clue that there was a problem was a rattling/grinding noise at idle - not as bad as in HM's video, but definitely there; it sounded like it was coming from somewhere deep in the engine bay, and it went away when you pressed the clutch pedal. I used a mechanic's stethoscope to confirm it was coming from the transmission. It's a pretty straightforward job to replace it, it's mainly just time-consuming, although I was completely unprepared for how heavy the transmission was and while I was able to use gravity to get it out, it was impossible for me to bench-press it back in while laying on my back. I had to call a mobile clutch guy just to wrestle the box back in for me.
FWIW, from the point of originally noticing the noise to actually fixing it took over a year. The car is my daily and drove just fine in that time. When I got the old DMF out, it wasn't *that* loose; I was expecting it to be in a much worse state than it was.
Great explanation of the VW DMF failure.
I had signs of DMF problems in my MK1 Seat Leon ASZ 1.9TDI (MK4 Golf), it started with a grinding feeling when the clutch plate engaged, but also a 'chattering' noise at the point of flywheel to clutch engagement.
Ended up fitting a stronger clutch plate and single mass flywheel, it was well worth doing. Yes there was increased noise and vibration at lower revs, but not something you would notice unless looking for it, none of my passengers ever questioned the noise.
Changing the clutch and flywheel took around 6 hours on a gravel driveway with a pair of axle stands and trolley jack. Certainly a DIY job for those with time and basic tools. (And the willingness to give it a go).
That car has been scrapped now, but it did 202000 miles whilst the body and subframe deteriorated around it. In the end I had to get rid of it because getting it through an MOT here in the UK was going to cost too much in parts alone for a tatty car.
The engine and gearbox.... Not started in 4 months yet cranked strongly straight away when someone came to take it off me. Thankfully the engine and possibly gearbox live on inside someone's MK4 Golf 😁
Had a severe failure on an ARL Seat Leon 1.9. Rattle on shutdown. Ran fine for a minute, then noticed the gearstick violently shaking back and forth and the vehicle making extremely unusual sounds as it tried to shake itself apart. I found multiple hot spots on the dual mass. That much play I'm surprised it was still in one piece. And finally, a hole in the bottom of it with something poking out. Surprisingly there was no damage to anything on the engine or the gearbox
Great vid! I have an '03 GTI VR6 with almost 150K miles on it, that has been vibrating a lot lately, and not shifting crisply/smoothly. It was just diagnosed with a damaged DMF and probably worn clutch. It amazes me that after 22 years of ownership as my daily driver, that the DMF and clutch lasted this long! Yes, the car has been garaged & 'babied' all these years, and maintained well, and driven normally (rarely aggressively). I've never changed the 6-speed manual transmission oil though. So even though i've had 22 year old oil in the gearbox, the transmission has held up nicely. Anyway, a local well respected garage that specialized in Euro cars, especially German, quoted me $1950 for the job, and they're putting in a SMF. The engine is perfect, so I could probably get another 10 to 20 years out of it, I figure!
Would you recommend a Single Mass Flywheel in a Daily 1.9 TDI 02M?
I like SMF in a mk4… but I guess with the low end torque in a diesel a lot of people say the DMF.
At the end of the day we out here trying to keep these ol baddies on the road as long as possible 😂
Soon I have to replace the clutch in my mk4 TDI but I am In dilemma Tu put smf or dmf? The last one is very expensive Your advice thanks
They say DMF protects transmission. On the other hand, second hand transmission is a lot of cheaper than a DMF.
Just of curiosity, did you switch to SMF and how it performed?
I loved the video Charles! I have a MK4 2004 VW Jetta GLI 2.8L 24v VR6 6 speed Manual 02M. Planning to buy a South Bend Daily Stage 3. Do I need to buy a new Dual Mass Flywheel, or should I keep the one that came with my car as OEM? I think mine is DMF LuK 240mm. Should I buy a brand new DMF from LuK that matches mine? Mine is almost 20 years old or should I switch to a Single Mass Flywheel? I hate to install a brand-new aftermarket Clutch of this caliber and keep the old DMF. If you recommend replacing the DUAL MASS FLYWHEEL, with a SMF brand model, will it go well on the MK4 platform for this car? Sorry for these type of rookie questions, I am pretty sure you get asked these all the time, my apologies, but someone told me that you are the MK4 expert in the whole east coast.
Had this happen on my last two VW-based cars, a SEAT Leon TDI (based on a Mk4 Golf) and a VW Sharan, the latter actually destroyed the whole gearbox. Both cars had over 100,000 miles on them. I replaced the SEAT's with a SMF and I really couldn't notice any difference in vibration. These days I drive an automatic Mercedes...
Yeah cause you drive over 2000rpm
@@teinepolaarsus6728 er... wut?
Great video. I have a DMF from a different make but the clear explanation and especially the video that showed the failing sound was brilliant.
I'm getting really sick of my "very reliable" TDI's. Even if the engine is good every damn thing else breaks or leaks on the stupid thing.
I hate those flywheels. I drive a Nissan Navara (Frontier) and about 50.000km ago the thing was replaced. Now it's back to the rattle in the can. This time I go for a SMF one. I'm sick of this cr.p.
@Hassan Ali And you probably drive a Ford... ;-) lol
@Hassan Ali Nailed it, didn't I? Lol
@Hassan Ali My sympathies, almost as bad. ;-) Hehehehe
Audi, VW, Same shit. I'd never touch one again.I'd way rather drive Japanese than German crap. Japanese way outlasts German crap with a fraction of the maintenance costs. I had a V6 Audi and while it was the nicest drive ever, it was also the most unreliable shit I ever owned and cost a bloody fortune to maintain. That's why they have no resale value.
SMF for me guys I'm tired of worrying about my dmf
What modern diesels have got SMF these days?...
And what about dmf for dsg? How can i upgrade it? I have a dsg tt 08 with k04 and flywheel die every track day... Sachs said that it only support 300 lbft. And my car have more than that. I already have tcu tune... maybe tcu problem or dmf are at the limit?
I had mine replaced on my VW this week to a Single mass. Noise is gone, car vibrates a little more, but hey..it's fixed! (2015 VW Polo).
Could something like this occur from a catastrophic event, say driving through water or something that could lodge between the plates if the car floats for a short period of time?
I don’t think submersion in water would cause such a failure. If you’re that deep in water you’d have other problems.
Why do I have a feeling you drove through a deep puddle
Will a single mass conversion do any damage to the gearbox or engine due to more vibration?
Sasho read stories of cranks snapping due to it
1 out of every 1000
More stress on the trans with a single mass.
I did this conversion and I am quite pleased of it. I have a polo 1.9tdi. There is some chatter noise it its bearable
Mine sounds just like that when I idle my Jetta. But it goes away once I rev it up from 800 rpm to 1000 rpm. Any thoughts?
Its failing if it makes any noise. Replace before it becomes more expensive
Just noticed it was 4 years old, my bad. Hope it all worked out ok for you
So what you did after 4 years???
VW DMF are ridiculously expensive. Smooth but expensive.
NOOOO Doubt!
In europe the kit is round 350e or $370
Yep in America they like to fuck everyone.
Bakanelli in finland flywheel will cost 650€
if you can wait few days for shipment from germany your good, otherwise your fucked by intermediary companies
in east Europe are some good shops that rebuild them (if the damage is not definitive) by resurfacing , balancing , replacing the springs, etc.
this is not possible for all models , it depends of the spare parts , quite hard to find.
the cost is around 180 $ / unit.
Get the single mas conversion kit guys. Done it several times - YOU CAN NOT FEEL DE DIFFERENCE.
Greetings from Germany!
totally!!!
1000 dollars for a DMF? Is it because of the fact it is sold in the US? For other cars they are much cheaper here in Europe.
Hi there, great video. My vw T5 has just started rattling about a month ago. It has got progressively more noticeable. It’s definitely nowhere as bad as your example in the video. It mainly rattled when starting the car and accelerating/going over bumps in the road. Just wondering if you think the car is still safe to drive for much longer? I want to go on a trip this weekend, only 2 hour drive, but nervous about something going wrong. Thanks
How long did you wait?
Did you ever take your trip?
Been searching for a few days on this problem, that's the exact same noise that has stated in my Passat b5 DSG, ive got a added squeel when deaccelerating, gave me certainty on what part to buy, thank you 👍
I bought my GTI new and the dual mass flywheel went out at 54K miles. I'm mechanically inclined and can fix most anything on a car. I skipped the warranty and replaced it with a one piece flywheel because I had intentions to do an APR flash. In the end, I decided against the APR flash as my car is plenty quick for me. I have 113K on my GTI on the original engine and the only other problem I had was the intake manifold needed replace. $170 for a new intake and I cleaned the intake valves while I was at it. My car has been great other than these two things.
Hey Charles, are the DMF failures more prevalent on the MK5 TDIs or the MK5 2.5 gas engines? I see tons of youtube failures on the TDIs only. I am suspecting this dual-flywheel wear stems from the TDIs low end torque coupled with spirited stop and go driving. I've never heard of a single mass flywheel failing BEFORE a clutch failing.
Hi, I'm waiting for the buyback of my TDI (Canada), my DMF started to make sounds 20 000 km (12 000 miles) ago and in the last month it started to slip when changing from 1st to 2nd. My question is: should I park the car and stop using it in case the DMF completely fails? Currently it's only when the car is cold, does it gives you any ideas on on worse it is ?
Lucas Côté had that problem myself and the dealer wont redo the work and wants another 1700 I should have got a solicitor but later on I changed it myself. Made to rip people off.
I don’t care about it failing everything does. How to fix it? How to make it stronger better and for less 💵
Learning how it fails is the pathway to making it better.
Most people swap it out for a single mass
I've been driving manual transmission cars and trucks all my life (61' bug, 65' mustang, 59' chevy fleet side, and currently a 2014 taco) and always thought smooth engagement was up to the operator! Never had chatter problems or longevity issues. Sound like DM flywheels are another way to up the price of repairs to me. Really!
Terry Goyan exactly how I feel about it
4 cylinder diesels in audis like 1.9tdi vibrate quite a bit, it is good having a dual mass. I had two 1.9tdi’s one with dual mass and one without it
Imo worth it
Although a lighter flywheel would be better for perfomance
One of the reasons for dual mass 'technology' is to prevent deterioration of gearbox components, many of which are now plastic or composites..so the DMF is meant to help prevent those components from failures...However, as I contemplate the replacement of my DMF on my VW LT35 (not available in North America butt basically a Merc Sprinter) I also note the very expensive replacement kits, as mentioned by Charles. 'Stealerships' will charge well over 1500-00 Pounds for replacement, including parts...You can easily find LT35's for sale or being stripped because these parts make them uneconomic to repair..Shame really, they are decent vans.
not every operator is going to super smooth with the gear changes the dmf also increases transmission life and is cheaper to replace than a broken transmission. I have seen cars converted to SMF and the transmission went out after a few months
i have a b8 s4, my mechanic says its the DMF and to go to SMF but i dont hear any noise, i just have a hard time getting into 1st/2nd as i think the clutch isnt totally disengaging when the pedal is depressed.
My 07 Audi needs a clutch job, mechanic quoted $1900 CDN for the DMF. Found that LuK sells them for $650 CDN.
Now just got 9 hours of labor to save for.
Ouch
How come you can't get a DMF refurbished IF its only a few springs worn or damaged in side of it? I'm sure they wont cost a $1000. Its just an other way garages rip people off
You are epic! I’ve got a VW Passat 06 and have heard this noise for ages. I thought it was probably to do with the clutch as when I depress the clutch the noise goes away ta-dah. That video you play at 2:29 is the EXACT noise coming from under my engine. Now I know what the issue is I can do some research before going in blind to a mechanic. Thank you!!
Hello ! I have a volkswagen cc tdi DSG from 2013 and i have to change the flywheel but i was wondering if after the change my car will go smoother , the car is vibrating at lower Rpm like 1200 - 1400 rpm , will the change of the flywheel resolve this problem also ? If u're reading and answering this Thankyou Verry Much ! :D
Good video, I am still curious what sound in early fail stage this dual mass flywheel has on vw golf 6.
Get that beard trimmed,it scares me being a being a beardie.! you would not be allowed into any workshop,especially drills/grinders/things revolving etc.. etc..they would tear you face off..!!
My 2005 mk 5 done 225000 km eng packed up. Reraired motor. Clutch pack worn plate. NO BURNT SPOTS ON FLYWHEEL AS WEL PRESSURE PLATE.
That's what I say, it's just Nut n' Bolts... No biggie really...
That's what they taught me in the navy. Even if it puts out 30,000 hp, it's still put together with nuts and bolts, and maybe an occasional rivet.

Hello, can you explain to me the Gds gearbox, the advantages and disadvantages, and how many kilos to change the oil, and is it the same as the normal gear, why some cars when the brakes are worn out, and some when the brakes are worn out? Thank you, engineer.
I had this seize up on my Subaru XV crosstrek after only 60,000 Km. Thought the clutch was bad. Turns out it died and killed my clutch so I had to shell out 2,000€ to replace both. Mine didn't make any noise at all. Just started smelling clutch burn.
Kermit the Frog
Useful comment , thanks . The exact same symptoms on my 2.5 Focus at 39.000 miles. No noise but burning smell and slight vibration on low revs.
Hey Humblemechanic I would like to pose a question. I had my clutch disc go qt 17k on my 2013 tdi. They knew it was a bad disc and stated they would replace with upgraded part. However I was able to see the part they took out it had holes all around within the friction material and the other side the friction material separated.
I had asked them to replace the DMF as well so as not to have to come back but they left the DMF. I was not really happy at all. IT has been 20k now and the clutch is exhibiting similar signs again. Why would the tech not replace the DMF at this time to avoid further issues.
gsleve That is a good questions with a lot of different possibilities. I sure as hell would replace the DMF. IT may be due to warranty costs at the dealer being high, it could be laziness, it may be that he just didn't know any better.
I think I will push this to a Q&A show if that is cool with you? I find it very interesting.
Great video! I got a brand new DMF sent but uppon inspection it has some broken chips on the outside circunference of the face, not the teeth ring. Nothing seems to be lose inside nor funny noises. Do you think I should send it back? Thanks
I have exactly the same noise coming from under the hood... but it's an automatic transmission on a 2006 jetta tdi... Does it also have a flywheel? Didn't think so, so what else could it be? Thanks for any suggestions...
low transmission oil or really dirty change it
question! If you drive too long with bad dmf can you damage the crankshaft bearings? Sory if bad english
I was changing oil in my friends turbo diesel 2006 Jetta, and heard the dreaded Rattle. She had 80K on the car. Volkswagen would not warranty it, so she sold it on Craigslist. When I researched the issue, I found it was a common problem, esp. for that year. I'm a heavy diesel tech., and early Ford powerstep kestrel had the same problem. I lost all respect for Volkswagen after that.
I have a rattle on my 15 Jetta TDI DSG. It’s sporadically rattles even with the belt off this eliminating ac and alternator. Does the DSG auto have a DMF? Car has 223000 miles fuel economy still 50 + mpg.
2006 Jetta TDI how much does it cost to replace clutch & flywheel? Book value is about $3,000 what do I do?
Georgette Fass I would fix the clutch. Even if it cost $1000. That gen TDI holds its value VERY well.
I have a 2016 Skoda octavia, 115000km on clock. I get intermittent rumbling when I start to accelerate from a stop. more so if i accelerate heavily.some people I have spoken to have said that it is DMF issue.

Maybe. There are only 3 repairs. 1) mech unit. 2) Clutch pack. 3) entire unit.

Would you or do you have any videos with a single mass flywheel commentary or review? id love to see you review the Valeo SMF kit for the 02M mk4... 6spd...
Can you just replace the springs or rivets. Rather than spend a load of money on a new DMF?
I’ve never seen one that’s serviceable
Hi Humble Mechanic!
I'm in the middle of converting auto to manual in my vanagon camper..
I have an 01 VW Jetta, TDI engine, and was running auto, but am going manual tranny, because I can install the LSD, and a locker option, while staying 2wd. :)
Is there a best technology/brand to use for DMF on this engine? Would you choose to run a TDI on a SMF?
I was looking on a AUDI TV channel video describing the advances in a design called "Dual-mass flywheel with centrifugal pendulum absorber". The video is at th-cam.com/video/YRxrajJCLr0/w-d-xo.html for reference.
I am unclear if the LUK/Sachs or other brands use this technology in the DMFs.. I actually emailed
Thanks! I love your videos!!!!!
149,000 miles on my '06 Ibiza 1.9 PD and the DMF has just started to knock. They can last a decent amount of time if you drive the car in a certain way, ie. not lugging the engine at low RPMs, not holding the car on an incline with the clutch instead of the brakes, not dropping the clutch hard and not pulling away without bringing the revs above ~1100-1200RPM
thank you Humble Mechanic
It’s a good explanation! A lot of shops will say it’s a bad bearing if they don’t know much about dual mass flywheels and they suggest replacing the whole trans! When I’m reality, it’s just a dmf.
Question, will a SM flywheel increase gas mileage due to less rotating mass or do the DM and SM weigh pretty similar?
No
Hi Charles, I have a rattling/vibration coming from my clutch system when in neutral but when I push the clutch pedal down just a half inch it goes away. Is this a bad throwout bearing?

I bought a 2009 TDI CBEA common rail with what sounded off like bad lifters. You know, that clacking noise..... Ordered from Latvia, replaced them suckers, put all back together to find out that clacking noise was still there. F....CK... Should have realized this was piston slapping from the beginning. Any tips or advice how to differentiate between these two? Think that will help a lot of us out there to keep from replacing what is otherwise fine and determine the real cause of the problem - this kind of problem at least. Thanks a lot love you videos for their simplicity and down to earth language.
My flywheel isn't making that noise but I think it's warped because my car trembles A LOT when engaging the clutch from a stand still, and it does not have much momentum so I have to accelerate. Can I just swap out my DMF for a solid flywheel or will my clutch not be compatible with it? I have a 2016 3.7L V6 Mustang and I don't have the money right now for a DMF replacement 😔

I have a 2013 Skoda Octavia RS 2.0 TDI 6sp DSG making the dual fly wheel failure sound, it only happens when the cars in park and engine is cold. Should I be worried about this? And if I want to get it fixed, I can swap it over for a single fly wheel?
I have to have mine done - diagnosed today - yes, very expensive job! You just mentioned a manual transmission, but this is a VW Passat with auto 6-spd wet clutch DSG. Is it essentially the same set-up?

Hello. Sorry to bought you with this , but my way to inform myself is a little obstruct by the information I can't find or I am to stupid to find .
I have a vw cady 1.6 dsg and last year the problems start with this car . First the megatronic unit brok and because I didn't have enough money to go to vw I used local mechanics how didn't know very good about the problem.
This year the head gasket below up on 120000 miles and I repeat it with Steel Seal but still have a lick somewhere , probably is the water pump, and with the water pump I have changed the belts to.
So my problem is, can I put a 2.0 litre motor with a different gearbox in the place of a 1.6 litres.?
Care to do a single vs dual mass flyweel on the same car, ex. VW to see whats the difference. Im thinking to switch to regular flyweel but I dont know how much vibrations is really.
Please Help, My ford focus has a dual mass fly wheel has over 160,000 miles on it I just installed a new clutch kit in July due to the clutch pedal falling on the floor & the ability change gear. I installed a new clutch kit but after 2 months of driving after the clutch pedal started to fall to floor and pulling the clutch pedal back up stop working. I replaced the master cylinder twice because I lacked the ability to build clutch pressure. I went to a transmission shop and was told to the clutch slave cylinder was the cause and was leaking. I replaced the clutch slave cylinder and was able to successfully bleed the air, build pressure and to get the clutch pedal was hard like it is supposed to happen. Upon engine start up the clutch pedal fell to the floor and would not rebound. I did notice that brake fluid was coming from the transmission. I contacted tech support and was told the slave cylinder over extended and busted at start-up of the engine. I was told by the tech support from the Master Cylinder manufacture to replace the DMFW because that was the cause of the slave cylinder over extension. I called the manufacture of the clutch kit and they felt the DMFW is working find and the pressure plate was the cause and to get a new clutch kit and to install it. So far I have not noticed any odd vibrations and unusually noises. I did notice with the fly still installed on the car and the pressure plate uninstalled that when I push on the edges of the flywheel it tilts a little. I am not sure if it is considered normal and should i just replace the fly wheel anyway. I do not want to put my car together for 3rd time and to have the slave cylinder to fail for a 3rd time but i can't afford to just purchase a new fly wheel just because. Is there a test can preform on the fly wheel to verify if it is bad or not. What do you suggest.
There's also, of course, the advantage of weight and resulting increase of moment of inertia, although that's probably not a big enough advantage compared to the NVH increase for a daily driver.
***** Agreed, I wouldn't go so far as to say lightened flywheels unless it's a track car but if mine broke I'd definitely go SMF especially for fast road use, comfort is not something I care about most in my cars, within reason of course. maybe when I'm old... but by then everybody will probably have EVs anyway and definitely no manuals :s.
I have an 05 Audi A4 2.0, manual and my car was towed and they put it into nutrual somehow and now my car has a mean vibration and it's like my clutch is engaged all the time. My car revs high when driving it like I am riding the clutch. Any advice?
So why has mine gone bad? Makes no noise and only notice it at idle, sometimes you don’t know anything’s wrong but sometimes the engine shakes like f***, until you put strain on the flywheel then it stops shaking 🤷🏻♂️🤨
Hello...i need your help..if you can give me some advice I would appreciate it a lot. th-cam.com/video/yPQKXYERb2I/w-d-xo.html
Do you know is its a flywheel issue or something else? It makes this noise when I press the clutch. I can hear it in first gear and in reverse. Car is a hyundai tucson awd diesel hybrid.
Well.... Fuck. That video at 2:20? That sounds a bit like my car. Maybe not with the same intensity, but it's getting there. Guess what i need to buy next.
Do they ever fail without warning? Was driving up a hill with no issues or noises and on the down side I put it in neutral to coast down the other side. A bit down the road input it into 5th and let the clutch out and the engine revved like it was in neutral still. Tried 4th and 3rd no go..... Pulled off and stopped the car, it felt like it would go into gear, but nothing when I let the clutch out.....
I uploaded a video on my account of My car making similar noise when starting the car, do You think it might be the flywheel ?
I have that thing but mines an automatic transmission. 2010 vw Tsi maybe I’m calling it something wrong

Something ripped my Trans in half (me) and I'm having a hard time finding a new one. Any tips?
Does this apply to auto transmissions? I have a 2006 Audi a3 2.0 fsi that makes that noise, auto 6 speed
On our car we have problem with, transmision, flywheel and clutch bearing
My 2012 GTi wouldn't go into gear one night. Turns out the clutch failed. With only 47K miles on it!! I find this rather shocking as my previous car was an '04 Golf TDi with 148K miles at trade in for this car.......it was on the OEM clutch still. I can drive rather fast at times and tend to downshift all the time. But still it isn't like I'm riding the thing or not matching RPM. But FFS 47K miles?!?
So, the OEM parts were some $1400.....said nuts to that....had them install a stage 2 kit with Teflon. Hopefully this one will last a bit longer!
Thanks for the video man! I'm going to watch the rest of your VW series for sure!
The clutch on my 2013 golf just failed at 50000km. The clutch plate failed where It is riveted to the springs. $1600 repair.
How can I get the single mass flywheel to purchase for my 2012 amarok?
My car rattles on idle but when the clutch is pressed it stops the rattle, golf mk5 19tdi bxe
Hay HumbleMechanic, You didn't explain why the DMF in your video has the center cut out. I don't want to get into if the dealer classifies this as a defect, but would you? How many other main drive train parts have to be cut out upon failure?

I just replaced my clutch nd pressure plate both brand new nd the car has no power after that can it be my dual mass flywheel. ?
The over consensus I'm getting from every mechanic who has posted a video about these dual mass flywheels is that they're junk. I've driven vehicles with both dual and single mass flywheels and frankly I don't see any advantage to the dual mass system, (or at least not to the point where I could ever justify replacing one with the same part). If I ever have to do a clutch job on a vehicle that has one, it's getting swapped out for a traditional flywheel.
+Rangerman9404 I like the way that DMF drive. To me it has a slightly smoother engagement. Not life changing, but nice. That being said, I am probably going SMF when I put a clutch in the GTI
audi quattro 2.5 v6 diesel sport avant 2004 dual mass fucked do they do a normal one for this
What the reason of noises when I release the clutch pedal and only when engine is cold and 1 or 2 gear?
