well, if the noise goes away when you press the clutch in, then the throwout bearing should be ok, as this is when the load on the bearing is the greatest..

I would probly look at a defective part, or an installation error..

how bad is the noise? we talkin' overly obvious, or you can hear it if ya listen for it?

Yes, the chatter goes away when you press the clutch in in neutral. I would best describe the noise as a true chatter, very similar to the dry clutch on a Ducati for us bike guys out there. Def obvious...

The real problem, is I have absolutely no interest in pulling the gearbox off the car AGAIN to deal with this.

bmwm750,

Seems like the chatter is common with the lightweight flywheel :

best performance mods.....

You might want to PM edevlin and compare notes...

I've heard this is normal from a few people, but I don't really understand why it would be. The flywheel is bolted to the engine, and simply spins with the crankshaft, so I don't see why you'd have chatter from it being single vs dual mass.

Maybe it chaters because of the lack of springs, as in the dual mass flywheel? I would suspect the dual mass is quite a bit better a dampening any chatter, whereas the solid (it is solid, right?) light flywheel has no chatter dampening.

The alu. flywheel is a solid mass,(well aluminum with a steel plate where the clutch contacts it..), If that was going to make noise, sumtin' might be loose...
