Just wanted a second opinion before I pull the trigger on a new clutch/flywheel. I have a 2019 Si.
Recently developed this knocking/rattle noise while driving, primarily from the driver’s side, in gear for the most part, very faint when coasting in neutral. Very pronounced from 1,800-3,000rpm range Doesn’t make any noise when neutral revving or at idle like a traditional rod knock. Had a buddy listen to it while I had the car in the air, sounds coming from where the trans mates to the engine. Less noticeable with the car in the air, less weight on the drivetrain so it doesn’t need to work so hard, leading me to say it IS clutch/flywheel issues. Honestly, I’m not too worried about rodknock/piston slap right now, based off of symptoms from a couple Z’s & Altimas coming through my shop. Haven’t found anything concerning in my oil. Change it every 2-3k miles. I’m FBO pretty much, stock clutch, threw the PRL flex fuel on, flashed the 27Won W1 flex fuel basemap on. 93oct with e85, running ~e35 mix, Castrol full-synthetic 5w30. New NGK plugs done like 3k miles ago. Did a couple pulls, clutch finally gave out and started slipping, now I have this noise. Anyone else run into a similar noise? I’m leaning on the clutch & flywheel just being toast Due to the symptoms and when they actually appeared. I can drive the car fine, just vibrates even more and makes that noise. Pretty much sounds like a failing DMF but, I can’t find videos of anyone driving on it, and they’re all DSG transmissions for the most part
I’ll attach a video later on. The one I took, the file is too large, I guess cause of iPhone’s 4K. Couldn’t find anything here pertaining to this kind of trans noise
