I am having the same problem car rattles from cold at about 2200 rpm

took it to dealer who said it was engine internal. But no real problem they suggested that if they cant get a fix from Porsche they would replace the engine on warranty

seems excessive but the rattle is driving me mad

I wonder if this has to do with ceramic coated headers...? This was a problem on some cars sometime in the 90's. IIRC, they would rattle when cold, but after the ceramic heated and swelled slightly, it resolved.
