Help me out guys. I’ve been hearing this knocking/ratcheting kinda noise for quite some time now, but couldn’t really pinpoint the circumstances it occurs at. Looks like on light gas pedal tap (below 1,500 rpm) it becomes apparent, like something is flapping around/knocking. Don’t hear it pressing the gas pedal firmer. No codes, fresh oil, looked at all live parameters and everything is in spec. I think the sound was around for at least 2 yrs, maybe even more
