Guys, add me to the list.. New LYN member & new Personarian... XD
PE Bronze Garnet M-line, WUP 6**6, Setapak/W.Maju/Melawati area
just got my car last week, but I've been reading the thread since V1!!

Thumbs up guys!!

I love my new car..But I'm facing some problems... Mostly noise problems..

1.Cornering or simply driving on uneven road, metal knocking sound. I understand that it's the steering assembly/orifice valve thingy.

2.Dashboard rattling noises when accelerating. Really irritating, sounds like some loose screws but I'm not so sure about it.

3.Buzzing sound from driver side aircond vent, from what I read it seems like it can be solved by reprogramming the ECU?

4.Door panel sound from front passenger seat. It sounds like 2 pieces of leather rubbing against each other when I'm driving, but if I wind down the window just a little bit, like a few mm, the sound is gone. Anyone encountered this before? Seems like the rubber is pressing too hard on the window glass when the window is fully up.

5.Door panel sound from rear right passenger seat. I have no clue where it came from. Everytime I go over bumps, there's a noise, as if there's something IN the door panel that's loose. Sounds like 'tak' 'tak'. And, the sound is quite persistent and it happens 9 out of 10 bumps I drive over, no matter how slow I drive. I'm quite sure that the sound came from the door panel because I can hear it very near me, like right behind me. So far this is the most annoying and irritating sound in the car.

Anyone facing no. 2, 3,4 & 5? Going to CoSE tomorrow, maybe to let them find out what's wrong & where do the noises come from. Then maybe order parts & make another appointment. Hmm..

Also, I'm planning to change my stock rims to 17' rims. The guy at the tyre shop suggested that I should use 215/45/17, but I'm not quite sure about that.. Will 215 be a little too wide & hit the fenders while cornering or overloading? E.G; 4-5 persons in the car.

Pls advice, sifu sifu personarians out there...

I seriously hope I didn't get a lemon... So far no prob with engine & all that, only noises... Loud, irritating noises..

Jack, are ur windows tinted? If so, what kind of tint are u using?

Let me address the situations one by one.

First, I guess almost everybody in their right mind would get a proper set of lock nuts if they ever change their rims. Common sense?

Secondly, yes, I've checked my tyre pressures. And nope, 31 & 28 psi is not too high for me. The vibration came from the engine itself, not the road condition/tyre pressure, thus causing the rattling noise. I've tried it on the smoothest, newest paved road that I can find in my area, and the result is the same. If you're suggesting that I should deflate/inflate my wheels so that there would not be any vibrations, you're not offering me a solution. You're just offering a cover-up to the existing problem. If a screw is loose somewhere in that dashboard, deflating the wheels won't tighten it up, if you'd realise.

No.5 - No, the problem is not with the folding seat. I'm very sure of that, because I had someone sitting behind while I'm driving & he confirmed with me that the noises came from the door panel. As I said, as it something is inside between the door panel and the door that makes knocking sounds when I go over bumps. And, I've already took the extra step to tape the seat hook even before the seat starts making any noise.

And No.4, if it's aircond noise, I can definitely identify it because I've sat in a friend's Persona before, and the completely different sound comes from the centre aircond vent, not side. This buzzing noise that I'm hearing, even with the aircond off, it goes away a few minutes after the engine is switched off. And did you read about other forummers that had reflashed their ECU to the latest version? The buzzing sound is gone, and I'm quite sure it's the same buzzing sound that I'm sharing with them.

As for the wider wheels, I'm asking for opinions because I'm going for aesthetics rather than comfort/performance. If not, why the 17''? The thing is, I'm asking purely for opinions on tyre size. I know that most Personarians here who run on 17'' wheels sits on 205/40 or 205/45. I wanted to know if there are anyone out there right now who's running on 215, and I don't remember seeing a post on 215/45/17 wheels on Persona. Maybe there is, but I might not be able to remember that (125 pages per V x 9).

I did expected what I will get when I placed the downpayment for my Persona. I just love Persona, & the problems doesn't stop me from buying it. I'm just trying to solve them noises. And it's probably you who are lucky to get a mint Persona, because I think around 7, if not, 8 Personas out of 10 out there faces the orifice valve/steering assembly problem.

Anyway, no offense and I truly apologize if any of my words above hurt your feelings in any way, or reminded you of anyone dead or alive. Cheers.

Finally, proper answers to my questions.

My car was manufactured in September.

I know, 45 is just fine, it's the width that I'm worried about. Will the front tyres hit the fenders when making a turn or a complete turn?

I'm beginning to think that it's the tint that's too thick that caused the rubber noise. Cos mine is security film from TintMaster, and it's kinda thick, to me.



Are you running on stock rims? Erm... I thought turning radius small = easier & smaller area needed for complete turn?

Anyway, do you have the complete info on CoSE's operating hours, etc? I can't find it on Proton's website.. & I'm on wireless, it's bloody slow..

LoL. Ok.. Anyway, even if they do not have time to attend to me, I'll just make an appointment on the spot for another day, & they can just get the parts ready for me & change it later...XD

....Dyno run? My stock car... Nah... I'd be disappointingly shocked by the results.. LoL.

Aiyo, I've read somewhere, someone dyno-ed a stock Persona, only 70+ WHP leh... I'm not prepared for such news. LoL. Ur's new car?

Hahaha.. Hard to say lo.. Our Persona also not that bad la actually.. Rite?? I tried before 0-100 in 9 secs.. Auto gear, play shift.. LoL. Better than me, my car abt 2 weeks old already 1800 km.. Crap..

Hey, do you know anyone who tried retro-fitting disc brakes into B or M-line Personas? I'm thinking of doing that.. Persona's stock brakes are too crappy..

I AM getting used to the brakes... But it doesn't feel good la.. I was thinking of changing the rotors to cross-drilled ones, and high performance brake pads to compensate for the crappy saga 1.3 master brake pump... I got quoted around RM 600 from EA.. Quite a good price, but currently broke now..

There's no need to change the master brake pump.. It's just the rotors and brake pads replacing the stock ones.. Evo3? Nah, not gonna EVOlve my Persona.. LoL.
0-100-0... Ok?? XD I don't wanna burn my wheels yet, gonna trade it in for 17".. There's a shop in Gombak willing to take my set of stock wheels for 1k..

Eh sorry... I forgot to mention that RM 600 is for changing them rotors + pads for front only.. So no modifications needed, back left stock.. But I'm not sure how much it will improve the current brake system.. Yeah, need to change servo if modifying the rear to disc.. I've checked, the rear set of disc brakes from original persona/gen2 = 1.1k

Sure, I'm interested to know too. But my friend did once if im not mistaken, it's around 7.5-8 kg plus for rims alone. Gotta rectify this by weighing my own rims
17" rims... I'm dying for it

U'd be surprised.. It might seem like a no-brainer, but it truly makes a lot of difference.. MyVivian last time also used this method... Brakes makan kaw kaw.. I don't know la, but maybe cos the brakes suits my driving style.. RM 600 for both brake rotors & 650 CC brake pads, I think it's worth it.. The way I drive, my brake pads usually go dead in just a few months.. And my rotors always bengkok wan.. E=brake from 200-0? Dude.. 150 also I saw my future d... How to drive 200?

LoL? Sure, I'll try to ask.. Leaving now, haha.. TTYL.

Just came back from CoSE. Apparently their schedule is full for walk-ins today, and I blame the accident at KM 50 Kesas for causing me to be late. Anyway, I was able to make an appointment there for this Wednesday, and the reception guy said that they'll check and fix all probs on Wednesday itself. Sweet.

Mesmerized by all the Lotus there tho o.o

One thing is, I'm quite impressed with the service and agree with the reception guy; I told him about my car problems and how the mechanics at PEKELILING SERVICE CENTRE handled them. They said that they've already solved the problem but the noises are still there, and they claimed that it would take up to 2 months to order a set of steering pipe/orifice valve. 2 months?? Seriously?? The receptionist at CoSE told me that it's ridiculous, & that they're just lazy. They didn't fix the noise problems and all because they're lazy, and because they think that they're protected by a statement in Page 13 of the Warranty/Service booklet, 4.1.10 "Slight irregularities not recognized as affecting quality or function of the vehicle or part, functional phenomena", No. 2 - Slight noise or negligible vibration affecting vehicle operation or function of components.

Slight? Hello, the door panel on the rear right passenger seat sounds like it's about to come off whenever I go over bumps. How is that slight?

Pekeliling SC mechanic: "Oh, itu bunyi biasa la. Kita tak boleh repair. Bukan under warranty. Bukak volume radio tinggi sikit tak dengar lah tu. Sikit je."

And in 4.1.10 - "Any changes occuring with time under normal use of the vehicle....."

My car only 1 week old leh. And I detected the sound 4 days after getting my car.

Screw them Authorised SC. I'm gonna service my car at CoSE after this. No more outside Authorised SC. I rather pay extra to get the job done, if there's any additional charges.

I asked them.. They said it's possible.. But then they ask me back "If wan retrofit airbag & ABS why didn't just get H-Line? U get leather seats, sport rims, front back disc brakes & double airbags too." I really that time. LoL. But it makes sense. The cost for retrofitting airbag & ABS is more or less about the same as the price difference between B-line & H-Line. And retrofitting will void warranty for the brakes, and you have to change the steering wheel cos B-line steering wheel cannot fit airbag.

I know, but I'm not sure Serdang where. I will take pics, of cos. Useful to forummers here

Yea, but I think the cost is not from the ECU tho. It's from the airbag & ABS itself..

Wah, how old are u? Student already can afford H-line? Mine was also because of the loan prob.. Darn PubIc Bank, 9 years x 4%... Damn shiong...

Last time my airbag deployed in my Myvi, it cost 7k to fit another new one. How much do you think the Proton's airbag would cost?

ABS doesn't work with drum brakes? If I not mistaken I've seen my Myvi's rear brake locking & unlocking very rapidly when my friend drove it.. Test brakes Just do the same style as Myvi lah.. Front ABS.. Enough d la.. Condemned Proton? LoL.. Must see what's the reason the car is condemned first... I'm sure you won't wanna spend your cheese on a set of brakes that failed to save it's previous owner, rite?

Yes bro.. But no matter how much it cost, the money spent is nothing compared to your own life.. That's why I opted for ML.. Altho no ABS but I can still have that chance of survival if I ever get into an accident.. Touchwood. Been through that once, never want it to repeat again

Denso Iridium XD

K&N drop-in o.o This is wear & tear rite? I don't think it would void the warranty, tho I wouldn't guarantee. Hey, it rhymes!

The spark plugs, yes, you might find a difference and worth. Easier to start engine, accelerator feels lighter & more sensitive. The drop in air filter, on the other hand.. It's washable, and it's much better than the original Proton's air filter, IMHO. I'm sure you've read threads here about how some Persona's air filter got bent, probably due to heat, and allowed unfiltered air into the engine. It's really not good.

Added on December 6, 2010, 3:22 pmThe last time I got K&N original for RM 120 wor.. Dealer's price, bought in bulk with 20-30+ other Myvians

O.o I see I see.... Hah.. Now I've got all the power under the hood to tapau Vios yet I don't dare cos no ABS. LoL. Life more precious lah. Last time always cry Myvi kena tapau by Vios. Now get to tapau Vios a few times also cry cos scared die. =.= But no ABS fun leh... Can slide here slide there
