http://www.amt.nl Het Valeo-DMF heeft radiale veren, waar het origineel van LuK gebruik maakt van boogveren. Het nadeel van die boogveren is dat de wrijving tussen glijschaal en boogveer varieert met het toerental. Dat probleem loste Valeo op met deze variant. Valeo leverde dit type aan PSA voor eerste montage. De constructie was te duur en ging in 2006 uit productie. Sinds 2008 produceert Valeo DMF's volgens de LuK-constructie.
VW TDI Dual Mass Flywheel DMF Nightmare
Dual Mass Flywheel(DMF) on a 2003 VW Golf TDI ALH 1.9L. The Flywheel was more then 15deg off (Twisted) and off-centered. That caused a horrible and unexplainable off balance wobble in the rpm range of 0-2000 rpm. The sound was similar to a helicopter. Apparently the DMF is only rated to 100k miles and have been know to fail in as little as 50k miles. Some have said that it is designed to fail.
The flywheel removal was impossible because the center mounting bolts were inaccessible. The VW experts said that you should be able to force the flywheel back into alignment to remove the 12 point mounting bolts. I tried that for about 30 mins. I was told that if you drill out the rivets that the assembly will separate. After drilling out the 8 rivets for almost an hour, only the surface that makes contact with the clutch came off. The center hub that was covering the mounting bolts remained. The last option was to cut the center hub to allow access to the mounting bolts. This worked like a charm and only took about 15 mins to complete.
Now if you were wondering the DMF and SMF have different bolts. The DMFs bolts are a 12 point Triple Square 12mm bolts. I used Lisle(tm) 4 piece Triple Square set part no. 60750 to remove the 6 DMF bolts with a 13mm socket and moly. The Lisle(tm) set has 4 sized (6mm, 8mm, 10mm & 12mm). The 8mm is needed to remove the 12 bolts from the left and right inner driveshafts to remove the transmission to access the clutch and flywheel.
Side Note: Always support you engine when you doing a clutch or timing job. In this video I was unaware that the engine had slide out of the passenger-side mount and was only being held up but the Exhaust manifold. This is not a good thing.

Audi dual clutch transmission technology
The S tronic dual-clutch transmission is a successful technology. It combines the convenience of an automatic with the efficiency of a manual transmission, while adding its own dynamic touch. Throughout much of the model line-up -- from the A1 to the A7 Sportback -- the S tronic is available in four different versions, with six or seven gears.

TDI Dual Mass Flywheel / Clutch Noise
2004 VW TDI 5 Speed DMF/Clutch noise.
You can see the longer start at the beginning.
When I press in the clutch it gets much louder. It got a lot louder just yesterday where I can hear it in the car.
VW Passat Dual Mass flywheel failure destroys gearbox
Just in case you wonder what happens when your Dual Mass Flywheel doesn't fail correctly. . Basically a small part of the DMF broke away and pierced a hole in the side of the gearbox. The vibration happens when I lift my foot of the gas. Once I put my foot back down on the gas it stops. Nearly 3000 euros worth of damage done to car. I have now installed a metal flywheel and new gearbox and the car is a totally different beast. Why did they bother with that crappy DMF!!!
