I think that the clutch surface gets more and more waved over time, because of some kind of oscillations which are the real cause of the problem.
Perhaps this document helps: http://www.schaeffler.com/remotemedi...loquium_en.pdf (page 23 ff.) |
Wow 22 pages of a 180 page document on clutch chatter! Father Guido Sarducci would say, “It’sa da friction. Dat’s all you gotta know.”
Regardless, I’m sure BMW will retrofit the flawed part soon. Thanks for the information. Good luck to those having the problem. Judder is a very annoying problem.
