Thanks, I have checked their website and reached out to them too. They replied that it's solid (single). On the other hand fiat seems to suggest it is dualmass so I am confused and not sure. That's why I was wondering if anyone with the same car might help. I feel a vibration on the clutch pedal when slightly pressed (if pressed all the way I can't feel it anymore). When releasing the clutch pedal I also hear a noise not loud but present (hard to describe but similar to a scratching noise ).
I have just replaced the right engine mount as the whole car was vibrating at idle, especially the steering wheel and I thought it was the flywheel causing that, but that's now fixed.
I don't think the vibration on the clutch pedal is normal though so any thoughts or suggestions are welcome. Knowing for certain if the flywheel is solid or dualmass would help. Thanks!
