New clutch - now vibration at 2500+ RPM

My OEM clutch burnt out after 80k miles so I had it replaced with a new Sachs clutch. The service replaced the clutch and pressure plate but kept the flywheel because they said it didn't need replacing. I don't know if they machined it or not.

After picking up the car, I noticed that it virbates more than before. The vibration can be felt at idle or when moving in any gear. It doesn't matter if the clutch pedal is depressed or not. The vibration seems to come from 'the engine area' and can be felt through the acceleration pedal but mostly through the shifter. I have the OEM shifter. The vibration seems to get stronger after 2500RPM in all gears. I haven't taken it on the highway yet to see if it's worse after 5000+RPM. The car idles and runs OK aside from that. The clutch seems to grip very well and the DSC kicks in 2nd and 3rd if I floor it.

Can this cause any damage to the flywheel and clutch? Could the clutch not be balanced properly? Any ideas?

I have the same issue, the vibration is worse on the drivers side and will actually come up through the accelerator pedal. It is almost harmonic for me, with the worst vibration being if I am in 3rd at 50 mph.

As far as I understand the DSC, it is not necessarily good that you get it to come on. Someone can correct me here, but I believe the DSC comes on if your clutch is slipping. Again, I have a similar issue - but if I turn the DSC off, I dont get any wheelspin (this is why I think my clutch is slipping)

OEM clutch replaced at 80k miles with another OEM. Flywheel machined. I do have an engine mount that looks as though it is about to go however, which could be the source of the vibration for me. Who knows.

You don't machine our dual mass flywheels ... either leave it in place or replace it
