Recently I noticed that my engine bay have some kind of sound like something is not rotating smoothly... I tot it was the iafm, but my car do not face power loss while accelerating( last time my iafm faulty, i faced power loss while accelerating)... so i suspect it was the alternator that give out such a sound... my car is 2yrs old... nvr change battery and alternator before... izzit possible is alternator faulty? how to identify it?

my car have same prblm but i think not cause bt alternator... i think belting... while the engine cold in the morning, my engine got sound... & i test give the water at belting the sound got louder.... after engine was hot, the sound disable....

For my case, even after 45mins of driving, when I stop down and open my bonnet, the sound is still there >.< my car only clock at 30k km so far...too early for timing belt faulty since i remember timing belt can last for 80k km? The sound is like IAFM failure, "tak tak tak tak...."... but i only changed my iafm unit approx 6months ago.

U can easily locate the sound if u hear closely.

Regarding the IAFM,
I change mine for the 2nd time in less than 6 month on my BLM.

OH MY!!! IAFM so "fragile" ar? can spoil so easy? damn wei...i remember it cost around 200+... mine edi no warranty... din take the EWP thingy ... but i remember last time when my iafm is faulty, i can feel my car lag of power... keep steping on the pedal also the car wont pecut and i din even realize my iafm is faulty until a friendly SA from Melaka SC told me my iafm is faulty. The only way to identify a faulty iafm unit is the "tak tak tak" sound?

yes... i also change my aifm but once... until now so far so good.. true about the lack if iafm faulty.. i can feel it.. i change my iafm at 2009.... ask the sc mechanic about the price rm 600... he said the iafm price drop so far bcoz the faulty.....

[beemc]

rm600?! until now my engine bay still having that sound leh... but inside the passenger cabin i cant hear anything, only can hear that sound when i open my bonnet... the sound of IAFM faulty can be hear inside passenger cabin or not?

at my time iafm faulty, i can hear the sound from cabin... good for u to refer the prblm to a friendly sc. i think if the sound hear when open the bonet, like the motor sound of the iafm to pressure the air to engine....

[fakhrulrz]

about the price i hear from sc last in 2009, i think now the price maybe a lot less from rm 600...

Any other methods i can use to identify IAFM faulty except goin to SC?
