no no, not dual mass related, the DMF and clutch were both replaced 4000 miles ago, the noise when that was on its way out was quite unique, that was a cyclical rattling noise, this is different, i linked to a recording of my engine, if you listen to that the noise is at exactly 10.5 seconds.. its like a hiss/chirp

no different if foot is on/off clutch, no different under load/no load..
