Ready to race!
Had some interesting info on the dmfw setup this weekend. Guy at cars & coffee has an S4 with the biturbo v6.....fx400 clutch with the OEM dmfw. Chewed through the dmfw in 30k miles and had to do a whole new smfw and clutch setup. He said the disc was too aggressive for the OEM unit. Just a thought.
Could be that it was his original dual mass flywheel had already been resurfaced to much, because the dual mas flywheel with the FX400 6 puck disk is one of the most chosen setups for the B5 S4 2.7t and nearly all of those people daily driver their cars.
I have been selling CM kits in the Audi community for over 5 years now and I haven't seen anyone having that issue with the CM 6 puck or any of the other clutch kits I have been dealing with for the last 12 years.
But it does bring up a relevant question about longevity. My next question would be, how do we know the dmfw is bad?
butchered by autocorrect
Are you asking about the friction area of the flywheel or the spring that applies tension to the part of the flywheel that rotates?
It will take a long time till the spring gets soft enough, you can go thru a few clutch kits before it becomes an issue.
When the DMFW fails you will start to hear a clunking noise as the tension gets too soft, allowing it to rotate to quickly till it hits the full lock position.
Now I wish I did get a DSG lol
That is till the DSG clutch assembly needs to be rebuilt and then you will have wished you bought a manual.
