Proton IAFM Engine
Maybe this is not the right place to discuss on cars and motors, but I would like to share this information with Proton users who have similar problem. I used to search for related information in few car forums. Of course they help with some clues but most of the comments are irrelevant. Therefore, I hope this post helps those who are looking for information about Proton IAFM engine.
Proton has implemented the Integrated Air-Fuel Module (IAFM) technology on their recent products including Proton Persona and Proton Saga. Without any argument, the technology is an advantage in the performance and fuel saving wise.
My family bought our Proton Persona last year and given the chance to upgrade to Campro IAFM engine by adding only RM500. Without second thought, we took the offer. Overall, the car is cool. (except some noise from the dashboard).
After the 10,000 km service, the engine started to make noise. It’s kind of wind sound (like water boiling sound) when the speed reach 110 km/hour. Not only that, when the vehicle slow down after the ‘high-speed’ run (just to describe this scenario..ahem), the sound can be heard clearly too especially when the vehicle started to move.
I started to search in the car forums, hoping that someone is already come out with a solution for similar problem. Unfortunately, no one is having the water boiling sound. However, some of them were talking about the noise from the IAFM. Taking for granted, I assumed the noise is caused by the IAFM too.
So what is next?
Some suggest to replace the IAFM before the warranty end. And one of them suggest to replace the defect modulator which will eliminate the noise.
I sent my Proton Persona for the forth service last week. I told the mechanic what I have read from the forum and requested him to replace the modulator for me. He agreed to replace the modulator but he told me it was definitely not the modulator which causes for the noise.
What cause the ‘wind’ sound from Proton Persona engine?
So far, he did not receive any complaint on the ‘wind’ sound. And while he was testing my car, the noise does not exist because the engine was not exhausted enough I guess. Any way, he suspected it got something to do with the vacuum valve but there are few of them in total. Some more, he did not hear the sound at all, so he neglected my first complaint.
Then how is the noise of IAFM sounds like?
It sounds like the old taxi engine (tak tak..tak tak….) When he stepped on the fuel pedal hardly and I can hear the noise. Then I asked him if I can replace the IAFM? Yes I can, but there are 30 cars on the waiting list. Some of them register for the second time because the noise appear again after it was fixed.
Any way, i decided not to go for the replacement. You know why? When we were in the middle of the discussion, a Proton Saga BLM came and the IAFM noise was so loud. It was clearly heard even with the car bonnet covered. I rather not to take the risk, who knows the noise might become worse later.
If the modulator does not cause the noise, what is it about?
Rather than making noise, it is actually controls the fuel meter. For Proton Persona owner, do you notice that the fuel meter never show FULL even though you have a full tank? Tell the mechanic during your next service and they will replace for you. Make sure your warranty is not end and bring along your car grant (photo copy will do). The modulator cost more than RM400 in the market, wao..
My front right wheel is making noise when the road is not even, what is going wrong?
I hate the first mechanic, he tried to ignore all my complaints by staring at me like he did not know anything. (I would like to clarify that, he is not the one who explain to me about the IAFM and the modulator) I asked for the supervisor instead. This time, he asked me to drive and show him the wheel noise. I drive through some uneven road and he noticed the noise.
But guess what, he declared that he could not find the cause after checking for half an hour. The solution for the ‘wind’ sound and wheel noise is to send my car to the Proton Service Headquarter at Shah Alam. They are just dealer who fix standard problem. Okay, I got it.
If any of you out there who has similar problem and got a solution, please share with me.
I have bought persona H line, since day 1 having an issue like late respond on breaking system even the services include as Electronic Brake-force Distributor (EDB) and Anti-locking Brake System (ABS). There is some other minor problem like (Air cond outlet spoil left hand side and ect… that I never bother. I also found same problem as you facing “My front right wheel is making noise when the road is not even”. I went to few service outlet at rectify this issue, but still unresolved. Lastly I went to Glenmarie (PROTON PARTS CENTRE) one on the mechanic inform me it could be problem on staring rack. He inform me to call proton i.care centre and report to them.
I have call to i.care customer feedback centre, they inform me the issue still under investigating and there is many customer have complaint on this issue but till now haven’t take any action due to their manufacture which is “PROTON” did not provide any solution for them replace the parts. VERY GOOD SERVICE!!! I don’t know when they going to solve this issue, finally I’m decided launch complaint to Hal Ehwal Pengguna e-aduan@kpdnkk.gov.my.
hi guy,i jz booking a b line prsona….haven take yet….but i till vy wori bout the quality….can giv me some comment
hi see toh,
besides the standard local made car issue like dashboard loosing sound, proton persona is still a good car..i have friend who bought one with no issue so far, that’s is his luck..
therefore, if you plan to have one..you might go ahead..petrol saving, power and price wise, i guess it’s a good choice..
if you are unfortunate to have some issue with your proton persona in future, what you have to do is to go to the service center more often..hopefully they could solve the problem for you..
some more, the car has been launched for years..they should have improved the quality for the newer batch..
just my two cents..
hi,noname
thank for your comment…wat u say was true…this car reli value for money.45k got 1.6l engine,family size car and high performance.think tid time proton reli work hard for ti.
Fuel modulator problem as stated above is due to the modulator cannot provide sufficient current to the meter and this only happens to Bosch Modulator.
Basically tak-tak noise is due to 2 problems and both are in Proton Bulletin Recall as I type this.
1) There’re a batch of IAFM is having such noise due to freeplay in the internal mechanical structure
2) There’re a batch of Campro engine’s timing belt pulley giving out similar noise as it’s wobbling when the engine is under load.
Dealer might not aware of this but a Proton Edar SC will quickly identify the problem.
Hi,
I know this post is overdue, but Im so glad to find out there’s someone having the same problem with me! The wind sound really annoys and sometimes quite worrying! So far I dont know what causes the sound. I didnt complaint with SC because the sound is on ’sometime’ basis. uhuh.. if you find out whats the problem.. pls do tell..
hi there Gen2 user, thanks for dropping by at putra permai community blog…
so far, i’m still not able to figure out what causes the ‘wind sound’…but i’m pretty sure it got nothing to do with the IAFM…i have my IAFM replaced two months ago after the SC mechanic confirmed that it was malfunction…but the ‘wind sound’ still exist after that..
i have complained to the SC mechanic but they said i need to book for another slot, purposely to test the car with me…since they claimed that they did not hear the ‘wind sound’ during the testing after service..but i have not do so yet
same to you bro..if so happen that you find out what is the cause, please share with us here…
note: one of my friend said it might be something to do with the compressor
Hi,
I jz got my new persona elegance last week, me also facing the same problem, my front right wheel and dashboard/steering area making flimsy noice when the road is not even. Can anybody advise me what should i do? bring to SC or direct to glenmarie? is there any solution? from what i heard, the technician always give bullshit excuses during complains. i’m planning to send my car for 1st service at Proton SC Bukit Puchong, anybody here got any experience at Bkt Pchong SC?
Wao Jai, the elegance is nice
What a coincident, i service my car at the puchong service center…the industrial area behind the binary college…i guess they are fine…the firm noise at the front right wheel can be fixed…i used to have the same problem too but it is okay now…just tell them the problem during your first service later..
enjoy and welcome to the persona family..
Yup its a very nice car…TQ bro… lucky i dont have any prob with the engine…is luck also…
no problem bro
share with us if you have any other new information about your persona…
Persona or Myvi? which one better, since the price of persona and myvi are almost same.
Please give some advice cause i plan to buy a new car.
hi ant, it’s a very subjective question…
i believe both persona and myvi owners will prefer their choice respectively…
check this link out http://forum.lowyat.net/topic/556814 and you might get some ideas..
hi there.. just got my persona elegance about one month ago.. for the problem that you hear like boiling water, i think it is same like me.. i’ve sent to service centre and do complain about that and they told me it is normal sound due to aircond compressor… and this noise only can be heard when u on your air cond…how about you? do u hear the sound even the aircond is off??
i think it got nothing to do with the aircond..the sound still exist although the aircond is switch off…but the sound will only be heard when the speed is more than 100km/h and even after i have slow down after that..
The new persona elegance really impress me a lot. I was thinking to get one to replace my 14 years old iswara aeroback. But after reading the feedback and issues, I am very disappointed by Proton. After so many years in the industry, such problem “dashboard/steering area making flimsy noice” still exists. Is a RM60k (if H-line) car, Persona shouldn’t have such “local made car dashboard loosing sound” issue anymore.
Secondly, from Mr Amer feedback, persona elegance still have the same problem “hear like boiling water”. So, meaning that persona elegance still inhererit the same problem which happen from previous version persona. Proton NEVER rectify and resolve the problem at all. But just changing side mirror with signal light, rear LED light, skirting, and front grill. so disappointed.
newbuyer – I’m also thinking to replace my 11 years old Isware for Elegance or Saga but after surfing here and there … found out that Proton “Talk More” then “Solve More” … Once U purchase it … then U will be “regular” customer of the SC!
I wondering what are they doing – Engineer – QA/QC – Purchaser ? Playing PSP / Computer / Online game in office ?
Isn’t that they have fully tested it before release the product into market … I suggest those not doing their job – do pls just resign let those who really want to help Proton to grow rather blocking their direction.
i got my persona elegance H-line (auto) 1++ mth ago and its mileage is about 2200km. I had sent my car for 1st 1000km service in Johor Jaya PE SC and used Petronas Semi Synthetic Oil for RM 150.
It’s really a nice car judging from its appearance and pricing, but from performance wise, the handling, fuel efficiency and acceleration is still not as good as Vios/City. I found the engine responded slower than it should be compared to my friend’s Vios. It takes about 5 seconds to accelerate especially after i stopped at the junction. Besides, my engine had dead for twice thus far when my car was idle (free gear, at the traffic light junction) but fortunately i can restart the engine after i switched it on again. The other issue is when my car stopped at the traffic junction which is on the high rise area, my car would still go reverse even though the gear is set at D4. I heard from my friend that Auto gear car are designed in such a way that it won’t go reverse when the gear is set to D. I think i should send my car to SC tml to fix all these problems…
Hi guys,
I bought a persona elegance last month.
Yes it has the “hisssing” sound since my first day, but not while im doing more than 100kmh, it happen when i turned on the aircond. In fact when to the SC in ampang, as usuall they didnt find anything wrong.
Second is the “front right wheel and dashboard/steering area making flimsy noice when the road is not even” this is very annoying as it quite scary when you r driving. Seem like smthing when broken or break. Also when to SC to check on this, again not satisfying answer.
WIll call the i-care and ask them.
daniel, cheaper price for a few second slower…i guess it’s worth
faiq..i’, very interested with the steering sound issue…actually not only the sound, you will feel your steering is loose too when the road is bumpy…for twice i had bring up this issue to SC when i sent my car for service, they claimed that they have change something for me..it’s for the power steering but soon the same issue will occur..
so, do let us know if they are able to solve your problem…
Hello…Got my persona elegance AT briliant red last friday. check thru the car wen collecting it. found tat the gear knob couldn’t change from P to R or D…etc…stucked…changed forcefully n it is like going to break it…then get it dealt with at the SC. but wen bringing it back, cant shift it to P when parking @@. At the same time, the front passenger side door’s lock cant be opened when using remote control. super hard to pull up to open it, again did it forcefully. so decided to go back to SC. Found out something broken in the gear knob, wat kind of QC, wondering in my mind, broken stuff in new car. was told no stock to change it, n they will call me wen there is stock…and wen trying to demo on the lock’s problem, it seemed ok. but it came back wen i reached home. it seemed to come back after leaving for some time. so decided to go back on saturday to get it dealt with. they tot is the button too tight and scrapping off some plastic to try to solve it and was informed if problem remained then it is some mechanical part inside…n today is sunday, it happened again…so surely something is not right…sigh…
n wen pressing on accelerator, during transmission of gear, it seems like it is vibrating during transmission, my feet can feel it wen pressing…wondering if it is something wrong also @@
Hi…sent my car for the 3rd time to SC…gear’s problem resolved, but the lock at the door for front passenger side doesnt seem to resolve…they changed something during the second time but it comes back…today sent for the 3rd…it is really inconvenient to need to send for so many rounds, especially when u need to work…i really hope i wont need to live this kind of new live after getting this car…
I’m driving 2 yrs old blm, 1st IAFM module change was 8 months new car due to tak tak tak sound and was ok until 4 months ago where its back.
I don’t have warranty for my car already, any1 know the price for changing this part ?
I’ve found out that when this problem will lead to high FC.
hi eric, i remember the staff at the service center did mentioned to me before it’s about 1k ++ but i do not know the exact amount…maybe you should inquire at the sc during your next service..
my 10 month persona is giving me headache…..it gave me tak tak tak tak sound all the time…. is it because the iafm module problem?.. going to what so call ‘ centre of excellence’ tomorrow to rectify the problem….
most probably it’s because of the IAFM…they will check for you and advice you to change if it’s defect…
recently my car also come out the “tak tak tak” sound problems, just solve at CHOON SHENG AUTO SERVICE (at bdr putra permai, jlu 3/3). the mechanic told me that is the wheel problems… may be u can try it.
ya,proton car alway got that problems, the wheel problems, tak tak tak sound can be solve at the workshop,but after few mth will come out the problems against, bc it is the car fitting problems, the quality of material problems.
IAFM engine is not suit for all the car to use, bc it is up to ur car power. i heard from mechanic advice, it is not useful and fix it just bring more problem for the car only…
i driving my proton persona 7months ago, it give me a lot of problem such as break system and noise. I just change my brake pad and disk brake yesterday, it cost me RM400. Last week i just almost having a accident at Sunway due to my break inefficiency. The following is my proton persona problem:
a) break system (M Line)
b) noise at behind Sit, however i put umbrella behind the sit to stop the noise
c) proton accessories poor quality
i so disappointing about proton persona, i decide to sell my car next year if my sales was improving. I worry about this car safety issue such as break system and cornering. I drive viva 660 before to do sales, it never give me any problem, what happen to proton ?I will never want to buy proton car any more, better i target Toyota vios 2006 version.
Hi, I have experienced the wind sound after my first change on the ECU unit on my Persona Elegance M-Line at Glenmarie due to engine check light always ON. The engine produce wind sound and loss power when i step on the throttle. After my second change on the ECU again, it went back to normal and with great power.
For the front-right knocking sound, the kind Glenmarie technician help reduce the sound on my first visit, but he said it is impossible to totally make it disappear. He claimed that was the power steering unit and it will only create the sound when we steered on the uneven road.
When I first get my new car, I have 8 problems and more and more problems appear when some have been fixed:-
1. Engine Check Light always ON
2. Rear boot cannot be opened using key
3. Hazard light switch panel not function
4. Front passenger door knob not coming up
5. Right front knocking sound on uneven road
6. Rear seat vibration sound
7. Braking sound is tremendous
8. Windscreen water leakage
I have gave Proton a second chance but still the quality is so bad. Not only on their cars, their service centers too.
One thing for sure, I will not purchase a Proton again for my next car!
phew………………. i have actually decided to see pesona sales person tomorow; but i think now that i have so much infor from you guys ( big thank you); i will not purchase a pesona la.
but what do you think of proton new to be launched inspira (mitsubishi lancer rebadge) ya?? heard 1.8cc is going for only RM75k… tru or not?
yes, the inspira 1.8 manual is about 75k only..the appearance is almost same with the original lancer but maybe not expect too much in terms of power..but if you are actually aiming at persona in the first place, the inspira might be a better car then
i heard that the first 200 model of inspira is japan setting, all original, just put the mitsubishi logo with proton, thats all. but later one will be malaysian made, since the ‘die’ is still not ready, (just what i heard from my friend which his friends work at proton building the machine)
i drive a 2008 proton persona h line~~never had any of the mentioned problem except for the sound from the rear seat which it had been resolved~~i think for proton car, it is your luck~because some can drive without a single problem happening to the car. i avoided accident almost thrice thanks to the abs that really function. for the car, getting to know it is the key point. i full throttle it before which the sound is really loud, dont know whether other car is that loud because my previous wira dont sound that loud even reaching the red line. My FC is also quite satisfied as a full tank filled when the tank is really almost empty which maximum reached RM70 for Ron 95 can clocked up to 450km sometimes pushing the car real hard. I once clocked 512km for a full tank without hard driving. (i must tell that the FC of my car is in city) if travelling on highway, from jb to kl just took me half a tank. i am also able to run at 170km/h thats so far that i dare to go.
izinkan saya promot untuk sama2 berkongsi gambar dan pendapat… di Blog Prodas.. bagi sesiapa yang mahu perkembangan serta gambar2 Proton dan perodua..

I do have this “tak tak tak” ticking sound from my engine whereby Proton identified it as an IAFM issue. From the forum, someone stated that this problem has a tendency of arising again. Is this true? has proton found a permenant solution to this IAFM issue yet?
I just bougth my persona elegance 3 weeks ago, and having the same problem which is when driving through uneven road, there will be some noise from front wheel, dashboard or steering area. i went for the first service and has told the mechanic about this issue, but he told me to keep using the car first , if untill second service, still have the noise, then he will look into it. according to his explaination the car is still new, and he afraid might “the part might not yet get use to each others yet”
After read this forum, then only i realise this is “common issue” which almost everyone is having. Is anyone can recommend me which SC you go for to fix this problem?
Yesterday,when driving uphill, i heard some “tak, tak” noise from left front side part, but it only last for few second..
now istsrting to worry..
Hoping someone can recommend me the SC that they went to fix the problem.
Thank you in advance
Hi guys, was searching around and saw you blog here regarding saga BLM problem. well hope i can share some of my experiences about my saga BLM manual model 2010 .
(1) first week after i bought my car, i having the “tak tak tak sound” well we known as IAFM problem. i sent my car to proton HQ granmarie, they mention by tune the valve abit and the noise was gone. yes they was right, it gone but for temporary !!!
Until the next 2 week later, i sent back to proton HQ again. this time the sound getting louder and more noisier.
my problem maybe the worst case from others because i need to replace the whole set of the manifold due to the faulty IAFM. yes since under warranty, they decided to replace it all, but i need to wait for 1 week for spare part issue. replacement done all in just in 1 day and engine run smooth without any noise sound.
(2) when i reach my 20k for service time, i having gear loose problem, i didn’t realize it until i can shift my gear ( 1st gear and reverse gear ) without need press the clutch !!! fix this gear loose problem only by replace a small spring under the gear part which cost me only rm3.25 ( if not mistaken) at service center. they mention the spring need to be checked every 20k.
(3) my air-con having problem( i think when i reach 30k), which suddenly the air become so hot. the more you turn to high fan, the more hot air enter the car. well i sent my car to service center, they just smile and open my dashboard next driver part, which hidden the air-con filter part. yes the filter was dirty and after wash it, the air-con function normal back.
(4) i noticed my car the front side more higher than the rear side ( tyres part ), which the gap for front fender can fit 4 finger, while the rear only can fit 1 finger. the rear spring is soft for the BLM version so you might having this problem.
(5) my fuel meter seem weird, after i put petrol for full tank (rm55) it mention the meter at full rate, but after drive for few moment, the meter will show empty sign fuel. well at 1st i thought maybe my fuel meter part having problem and i sent to service center for check it. sadly, they didn’t do anything bout it.
few time when i put petrol (no matter less or full tank) and the problem keep happen again, i decided to check it my own self. i take off the back sit part and check the wire connection that thru to my fuel tank. noticed the wire seem like been pressed by heavy thing(maybe when back people sit on it). try to bend or straight the wire carefully, duck tap it nicely. and place back all the sit properly. since then, problem solved. try this, it might help.
p/s : well my car now reach 45k and the IAFM problem coming back….. tak tak tak sound coming back !! still under waranty?? replace manifold again??? same thing keep repeated again and again….
cheer !~~
i just bought new persona h line 3 months ago. but after one month of using it the car broke down. SC claim the problem due to fuse to meter that why when i start i goes straight to rpm 8. but the same problem occurred and they claim wiring then to ecu board then to the engine disk. this is very3 frustrating. been paying to the bank without using it for almost 2 months. sigh…..
I got my persona elegance on march 2011, well so far ok just that my car engine compartment got some area was got rust , new car also got rust @.@
2nd is the steering when turn until max got groooooo sound, if turn max and hold on position then rev, it will be more loud.
send to SC check, they just say is normal . =.= Un-normal loud sound = Normal ????
its good 2 know there are so many problems arrising from the new persona,will definately look out for the common problems mentioned,but got my person H-line on may 17,so far,the problem im having is:
1. Inside the aircond at d center there is this noise that sounds like something is loose,when u accelerate the noise gets louder,went 2 SC they say they will change the whole thing inside due to the part is faulty. ok? >.>
2. whenever I start my engine there is a whistling noise thats very irritating. ask the technician in SC he say its normal…
3,window at the back of driver seat,whenever I try to wind it up it makes a noise like the window is going 2 drop off, havent complain to SC yet.
4.front brakes is making a sharp screeching noise when braking like the noise we use to hear from old cars when they brake. but if happens sometimes only,but defienately fill complain to SC.
5.remote to oepn the car boot need 2 press 2 times only open,when opening it manually its really hard to open with the key and its feels like ur key is going to break only it can be open.
6. Even though I pump full tank the meter is never at F. havent resolve this yet as i forgot to mention due to other excesive problems. and its seriously NOT fuel saving. full tank can only drive less than 400km
Proton cars are very popular with many Malaysian ‘cos after more than two decades, they still produce cars with never ending QC problems.
Anything that’s really ab-normal, they’ll tell you it’s normal.
eg. sticky tape & glue are often found on their new cars to hold the bits-n-pieces in place.
When these items become loose and start to vibrate (eventually falling off), they’ll tell you that’s normal.
Over time, the staffs at SC become so bored about the QC problems that they look like zombies when you ask them to service your problem-ridden new car.
While all these are happening, the top management are probably enjoying their holidays overseas.
If you don’t buy their cars, they say you don’t support Malaysian made product.
If you buy it, they let you “enjoy” the QC problems while they may be having a good laugh.
proton se stop while driving
my pesona se just 1year got this problem so many time. engine stop while driving,steering lock,tyre lock… don know y. lucky not in a highway
how to nsolve this
This is definitely something serious…send to service center immediately
thanks for all the info… i always wanted to buy persona… coz i felt it is nice and powerful… i went to website and check… mostly they all recommend this car to ppl… but sumhow i dun feel right… coz in reality… ppl told me persona hav too much problems.. so i went to search persona PROBLEMS.. XD i found this website… with all the comment above… i had decided to choose myvi 1.5 instead… i had a 4 years myvi in my house… it does have problems like windows cant move… but it is still in good condition… no engine failure… XD and also no tak tak tak sound…. eventhough i dun really like the myvi design… but i rather have an ugly design car then a problematic car… XD thanks guys…!!!!
Buying Proton is still depend on individual luck..i’ve seen my frens drving proton without major problem.. While my proton is no longer a proton. It already becomes 80% Mitsubishi.. imagine that.
I bought my Saga 1.3 FL 4 months ago from Jakarta (Indonesia). The mileage is currently 4,000 km. It is a good car for its price and almost had never found any major problem. The only problem was the rear right wheel, it got jammed but has been fixed by lcoal SC and the problem never come back
In Indonesia most of Saga/Persona is used as taxi. Before I bought the car, I interviewed some taxi drivers who drove Saga/Persona. I asked them if there was any problem with the car. They said Saga/Persona is a good car, even after 300,000km (3 years). The only problem is the reliability of Saga’s suspension which is very poor and need frequent replacement. And also poor stability when cornering at relatively high speed (80km/h above).
Compare to their Korean counterparts : Kia Rio, Hyundai Avega, & Chevrolet Kalos, Proton still give better value. But due to scepticism of most people the resale value is below the other brand. Very ironic.
Thank you for sharing bro!
