How I recently buy my Alfa, after fiew days I started to see that my car shudders on startup(not sooner because I was using the clutch like a petrol car with more throtle on startup) and suspected that the flywheel is broken, but interestingly the problem passed away for fiew days and started to think that might be just water in the gear fluid(the engine was presure cleaned before I got the car), but the shudder still came back but not allways the same, sometimes more seveer, sometimes just a little but the shudder it is there around 70% of the time, especially after I go with the car 20-30 minutes.
More interstingly 3 weeks after I noticed the shudder a metal vibration sound came too when I throtle the engine between 800-1300 RPM.
Could all this be because of the flywheel? Or humidity geting in to the gearbox? Or something else? I want some opinions becase If I go to a service they will just start changing parts..
