Help with dealer repair dispute on Clutch shudder

DIGItonium · 10-07-2011, 04:21 PM

This experience is called clutch "judder," or the violent drivetrain shaking when trying to feather the clutch.

Mine was bad out of the box. One day (16k miles) the CSC failed, and got replaced. The judder nearly went away.

The shudder returned after about 1k miles. It happens only after the drivetrain is warmed up. I suspected something like the CSC as the dealer did not replace that when they replaced the clutch. It's now more of an annoyance than anything. Perhaps I'll get lucky at some point and my csc will fail as well...

No adjustments. It's hydraulic.

That's what I figured. Just saw all these people rambling about "adjustment needed" and wondered wtf. In my short database of experience, hydraulic clutches from the factory are self-adjusting for wear and that's it.

Part of me thinks this may be caused by improper clutch break-in. Shudder with a new clutch is normal. Shift it hard or otherwise abuse it until it's broken in, and you may have more problems to deal with that won't wear-in.

I had the dealer look at mine, and they agreed there was a definite problem. They are replacing it sometime this week. Is there anything I should look out for, or make sure they replace? Resurface flywheel?

if you aren't giving enough throttle the clutch will shudder. that is the purpose of the springs on the plate itself. Clutch 101 my friend. It is absolutely normal. Throw just a little bit more throttle in and you'll be a-ok
