My 2016 developed a rattle noise in the right front passenger area engine bay that occurs when accelerating under boost between 2500-3000rpms. When I'm sitting parked and I Rev the engine to 3000rpms there is no rattle.

Does anyone have this noise? My dealer said that the exhaust manifold valve can make a noise that he said is common in the Speed6....

Whatever,... It's not normal to me
