An important announcement coming up soon.

Added on April 13, 2011, 6:46 pmTO ALL FELLOW PPLYNC MEMBERS WHO ARE DRIVING PERSONA ELEGANCE:

If you have ever experienced sounds (tak tak tak tak tak) coming from your engine during cold start in the morning, then it MAY BE one of the infamous Proton's manufacturing defect: the IAFM problem. IAFM noise is most noticeable during cold start, and you may hear the frequency of the noise going up or down depending on the RPM that the engine is running at. The noise is identical to a diesel truck or lorry's engine idling noise. Once the engine has warmed up, the noise will become softer or totally eliminated. This is because the plastic components on one of the valves on IAFM expands with heat.

So far the problems that may be associated with IAFM noise are nothing major, but in certain cases it may cause severe throttle lag, and the noise may get louder over time. Some owners have even experienced increase in fuel consumption and bad engine response.

If you visit the service centre and the mechanic or service attendant tells you that the noise is not caused by IAFM as our Persona Elegance comes with new batch of IAFM modules, DO NOT believe what they said.

You may:
1.) Ask them to diagnose and tell you what exactly is the problem since they insisted that it's not IAFM module noise.
2.) If the mechanics at CoSE tell you that the noise is not caused by IAFM, go to a few different SCs, have them to check your IAFM module for imperfections on the valve, then get them to write a report each. Compile these reports & bring it to CoSE's customer service and file a complaint, give it to their higher authority.

Now, do remember that they may not be able to figure the noise out if you send your car to SC as the engine has already warmed up. Park your car and leave it there for an hour or so for the engine to cool down, then get the service attendant or mechanic to listen to the noise as you start the engine.

Again, I would like to stress on this main point as I've experienced this myself and wasted almost a month plus before sending it to a different SC just to have the noise diagnosed as IAFM problem; If the guys at CoSE tells you that it's not IAFM problem but your guts and 13 other SCs tell u that it is, then it IS IAFM problem. In my case they never even bothered to check as the engine has already warmed up and the sound was gone by the time the mechanic laid his hands on my car.

This serves as an important announcement to all Persona Elegance (PE) owners as to not overlook this small issue that may lead to greater problems in the future. The price of IAFM modules has dropped since year 2009 (from RM 1200+ in late 2008 to RM 2xx in 2011) because of the frequency of Campro IAFM engines having this problem. Still, it's our right to claim the IAFM modules as they are covered under warranty and malfunctioned units are manufacturing defects. We should not wait till the warranty period is over and then pay them RM300+ including labour to fix a defect that is there from day 1 of ownership of the car itself.

I hope all the Persona Elegance owners out there take note of this issue and do not keep an eye closed.

Salam 1 Malaysia, & Harap Maklum.

xandras,, u should let me see this 2 months ago... arghh....haha

Sorry lar, I also just recently found out & replaced my IAFM module.

so if iafm problem,the noise should be very obvious during cold start?

Yes, very obvious. At initial stage of IAFM going kaput, the noise is slightly softer, maybe even undetectable or covered up by noises from other part of the engine. Over time it may get louder and louder during cold starts.

Cheras KL area bro. Let me try to take it.

nais info....

Ok, will wait for ur video to be uploaded.

Hmm, in the end got persuaded to buy ENEOS 5W-30 for RM 105
Reason being, the shopowner guaranteed me satisfactory experience, if not go back find him lol. He said he himself compared it with castrol and he says Eneos is better. So im gonna give it a shot, if not im gonna shoot him LOL

By the way he is offering me RM 96 for Castrol Magnatec

Thanks Xan should put it at the main page for the common problem of persona area.
