Some say it affects performance, but I think it's mostly just noise unless the actuator for switching between the long/short intake is stuck. I heard that the rod may eventually break if it's left in its current state, so it's probably a good idea to get the thing serviced, I.e. Shorten the rod if I'm not mistaken.
Later I upload my video to utube den will post here cause I'm.not sure that sound is iafm or normal engine sound... It sounds like both to me lol..
yea, noisy a bit but no decrease in power or so.. loud screeching sound?
Screeching sound is high pitch right ? It's not high pitch when k hear it..something like trumpet sound..duno how to describe properly but its really loud.. Now they helping me skim my disc brake...see how it goes
Some persona have this problem, not sure what's the issue there
mine always got high pitch screeching sound when apply break in low speed ( <20 km/h), can help me ask them what is the problem? perhaps is the wet brake pads (since always rain recently)? I'm using ceramic brake pads thanks bro
Dem. Sorry bro. My phone out of battery just now..didn't get to ask for u ..
Guys, is it common problem for persona with steering audio control ? My vol+ mute vol- changed radio frequency instead of volume lol.. Den seek track forward, and backward change the source (CD/usd/radio) while the mode button does ntg lol
last time i had a chat with Proton mechanic in Glenmarie,they say the tak tak tak sound may came from 2 sources.
The IAFM and purge valve canister.
For me ,i will just replace the purge valve canister first.if your FC seem worrying from time to time.Change this.Much more cheaper and easy to replace.
CODE
A canister purge valve is a solenoid valve controlled by the Power Train Control Module. The Power Train Control Module is a control unit that determines the ignition timing, fuel amounts and other parameters needed to keep the engine running.
Function The canister purge valve serves as part of the emission control system in a car, and it measures the flow and amount of fuel vapor that is recycled into the combustion process via the charcoal canister, or fuel vapor storage device. Canister purge valves are also used in "leak tests," by allowing a vacuum to be created throughout the fuel storage system when the valve is closed, thus preventing outside air from entering the system.
Performance Factors that can affect the performance of a canister purge valve include unclean valve conditions and valve blockage. Valve blockage is caused when an obstruction becomes lodged in the opening of the valve, causing a backup of the fuel and air mixture.
According to the computer, it said 8.1L/100km. Mine is auto. Is the FC normal for PE? City drive only
Just notice my car tyre damn noisy on uneven road.. When I look at the tyre used by previous owner,
1) 2 biji is ecotopia or ecopia.. forgot exact name 2) 1 biji is bridgestone 3) 1 more biji I no see..
Btw, still got question to ask since Im new to PE. When I'm inside my car with engine on, after I unlocked the car door, I open and close, it will auto lock again after close. normal kah?
and now i notice got some rat sound when braking low speed. probably due to cheap brake pads
Yes if your handbrake is down. If your handbrake is up it will not autolock when u close the door.

As long as your hand brake is not engaged and you are pressing the brake pedal, your door will auto lock if you open and close the door, or if you press the brake pedal when your hand brake is not engaged and the door is not locked.
Edit: Should be Ecopia, and it is from Bridgestone.
oo..thats very good since crime is everywhere now.. some people after open door forgot lock back..
Previously no rat sound? I thought rat sound is like screeching squealing when low speed braking... By the way the stock persona's brake pads is noisy too. I solved my braking sound problems after I changed all pads to Treator Metallic plus.
Nope. Cc5 in my previous car is quite. Currently using bridgestone ecopia
Ok guys. Now when reverse brake no sound. But moving forward low speed brake got sound. Sound start noticeable at speed 60kmh below.
Most of the time is krok krok krok krok sound. Sometimes like got metal sound. Den got one is squeaking sound. Got a few tines is ngek ngek soubd. Issit brake pad problem ? Brake performance is okay jz the sound abit annoying. Already skim the disc btw
One more more thing is, sometime when I'm on uneven road, I can hear jit jit jit sound like rat lol

Had this problem since the day I got my car. Got worse since the mechanic removed the brake insulation layer. Noise came back about two days after applying lithium grease on the back of the brake pads.
Is the wooong sound very loud ? No solution at all?
With the insulation, it was loud but still acceptable. Without it, the sound is terribly loud and annoying. Luckily it's only when the brakes are not hot.
I think the only solution would be brake pads with proper shims to reduce noise and vibration etc.
Actually what is the actual cause of it? Will affect brake performance? I damn scare one day suddenly brake failed..
Try Googling for sources of brake noise. If the problem lies with the lack of noise reduction material on the pads themselves, I suppose that there's no reason to worry about brake failure.
Thanks. After googling, found that rust on the disc also can cause brake. Somehow my rear disc is very rusty while front discs not rusty at all lol..
Maybe it's because the rear brakes aren't as heavily used as the front pads. Get a bunch of people to sit in your car so that the EBD system will make the rear brakes work harder.
I'm currently searching for a proper brake lubricant, and it seems that it's very difficult to find them in Malaysia. . I'm going to pay a visit to Ace Hardware one day to see what they have to offer.
Hahahahah. Maybe since 99% of the time I drive alone.. Shall take a photo of my PE to set new picture ~
How do u define a proper brake lubricant? how to see whether is good or bad brake lubricant? First time buy own car lol.. So many things duno..still learning.
