hi guys, about cold start sound on cfe,its vvt sound, if it is really loud, i mean really loud, than its the ocv valve on vvt. I think the assembly line people already been informed about earlier errors by the line when overtightening the ocv valve. So stupid if the same error is reoccur. But if not loud really loud, then its a normal vvt operating sound during cold start.

About iafm+, maybe i care misunderstand ur inquiry. If the knocking sound is loud, i mean really loud as previous problem on iafm unit, then its iafm problem. Another thing that will associate with this prob is really bad fc n loss of power. But the earlier prob on iafm unit already been rectify by using better high thermal plastic from before. If a slow knocking sound,There are no loss of performance n fc is as before,i think its normal, not associate with iafm unit. But better send it to check when 1st service.

But u can check youtube on earlier iafm unit problem, on how its sound. It is really loud.

rasa xda kumbang kot coz klu ada, exo bold cfe akan di update sekali. Tp xtaula, xdpt info lg.

Erm, hope everybody clear that cfe doesnt have iafm, but used fix resonance, while iafm+ unit come with variable resonance, the iafm unit.
