no. there was nothing shown. everything seems to be normal to me. but i do feel the kick not so powerful already unless S button is turned on.

So u pay 580 for the respray ? My door just a very small dent. To respray cost 2-3 hundreds.

Brand new Civic couldn't move which just came out from sales office less than 10 mins. Whichever brand also has problems, bear in mind

After the SC fix your problem,try to get as much details as possible. I believe we all can learn from it. Tks mate!

Hi,
Hope that your issue nothing related to carbon built-up. Read some comments from 308 FB as shown (highlighted).



Pugs Tkl: Mileage 21k. Gentle and town driving style.

Ismail Ali: Very nice and even looking carbon coating..

Pugs Tkl Ismail Ali : Yup pal...and thats only at 21k..

Razuani Rahman: No wonder when my 508 at 18k km I can feel the jerking and lost of power ..bro TKL did any 408 or 508 recently..

Pugs Tkl : Encounter only 408 once and 508 twice...The rest of Prince is 308,3008 as well as Mini..

Razuani Rahman: Waa 408 got also ..is it as bad ..the..508 month picture..how bad is the carbon buildup and at what mileage


Pugs Tkl: Razuani Rahman The owner did not answer for my permission to post their photos and info, so I have to keep this to myself..

After so many that I had done, it varies with every car. It is more depends on the driver as well as condition. Engine oil also play important factor coz oil which unable to withstand the heat or not so good quality after 5-6k km will create more vapor and burning. Besides that, those treated with chemical valve cleaner will have faster build up since the layer of carbon is already soak with chemical and then dried up again with more heat. Lately, I witness few cars with corroded coating on their intake valve. Everytime after cleaning, the valve should be sparkling clean,smooth and shiny coz the cleaning will have polishing effect. There will be some left over carbon at the end or corner of the valve which will flakes off by itself once the car start to run and temp build up.The smooth surface have better and smoother finishing compare to a new valve and should takes longer time for the carbon to build up. The few cars that have corroded coating will eventually have very much faster build up and I am unable to give it a good clean and polishing no matter how hard I tried. I have no idea currently what causes the coating to corrode and it looks like the coating is gone and start to rust, Besides that, it had a rough and matte surface. I will post some pics once I got permission from respective owner..

However, build up is there as low as 8k for first layer and it will increase over time and rob power. This will be the same as other DI engine as well but Toyotas build up is slower on their DI engine.All the above is based on my observation and for info sharing purposes.1 cent.


Razuani Rahman : On the engine oil, what is the best brand for the THP engine..

Pugs Tkl Razuani Rahman : Unable to comment much coz I only tested few brand on THP. Total and Amsoil with not more than 30weight is good. Not going to comment what is not good...LOL




BUT, some said that our new prince engine which is after upgrade to 6 mods seems like no carbon built-up issue. Read from PCM FB as shown (highlighted).



To overcome some the prince engine issue, Peugeot has upgrade the engine use in 408T among other as follows

Engine code P6CDTM (408T) carries the following mods:

1) Engine tuned to run on RON 87 petrol
2) Remapped ECU
3) New designed piston
4) New designed catalyzer.
5) New engine oil filter housing with heat exchanger
6) New turbo charger
7) New fuel tank gauge unit with lower pressure pump to handle lower grade petrol.
A fuel filter to cater for hash atmospheric condition ( third world country)

This has drastically reduce the depollution issue on the prince engine at the same time hp is increase from 156 to 163. During trial period before it is launch, the car test car clocked more than 60k km without carbon built up issue. lets hope it stays that way .



Ermmmmm....... JUST SHARING MY 1CENT. CORRECT ME IF I'M WRONG.

Glad to note EP6CDTM was test run for more than 60k km without carbon buildup.

Was this your spy shot.Good job bro.......lol Jap box aslo kena tow

This morning went to Sierra Glow to look for Mr. Choong, saw a new white 408T, with WYE plate doing the coat, owner here? Hehe...

Ya bro skyjack.

I hope it was correct information.

Posted by the car owner.. Heres the story:
Hi all,

Some of you might know what happened to me....so this is what happened few days ago.

I bought a new Honda Civic 2.0s (without GPS) from Honda Setia Alam. I took the car on Wednesday April 3rd, and drove it out around 4.10pm. I was driving around 40km/h since I was in the housing area....and tested the ECON mode. Nothing special. So I turned it off and reached the second traffic light.

Once it turned green, I tried to drive, but the car refused to move. It was like you have your handbrake ON. I could only reach 10km/h MAX. And if I lift my feet off the pedal, the car stopped IMMEDIATELY. This was like...less than 2km from the sales office?

So i stopped at the road side (luckily no car around) and called the sales guy. He said maybe no petrol, maybe hand brake didn't put down, maybe need to ON and OFF engine. I tried all, but still same. Then i forced it to drive back to my home about 1min drive away. Stopped there, and asked the mechanic to come (initially they refused).

When they reached my place, the mechanic confirmed the car should not be moved anymore. The car could not even be reversed. So they had to call the tow truck. Yes, brand new car, drove less than 10 minutes, need to be towed back to Honda Service Center.

I escalated the case straight to Honda Malaysia, even to Level 2 Customer Service. But the conclusion they came out with is - they are going to close the case because the issue has been "FIXED".

So I asked for more clarifications.

Alvin: Do you know what is the exact issue?
Honda: No.

Alvin: Then how can you say it has been fixed?
Honda: Because we could not recreate the issue in the Service Center (even the mechanic who went to my place was confused).

Alvin: Can you guarantee the car won't stop immediately while I was on the highway?
Honda: No, we cannot guarantee because anything can happen while you are on the road. And it might not be caused by this.

Alvin: So you are asking me to risk my life because you don't know what is wrong? And you assumed it has been fixed?
Honda: *silence*

Alvin: Then what have you done to the car?
Honda: We suspect there are some particles interfering with the sensor...causing the car to stop immediately.

Alvin: Huh? Why Honda cars can stop immediately with a bit of particles interference?!
Honda: *silence*

Alvin: You all said the car has been tested OKAY for 2 days. But the car has been with Honda for MONTHS. Yet, I drove 5-10 minutes and it stopped. What is your explanation?
Honda: We have done what we can.

Alvin: Can you all be sure that the fix is permanent?
Honda: Sorry, we cannot give this kind of guarantee.

Alvin: OKAY FINE, then can you give me a report of what has been "FIXED"?
Honda: No, we cannot do that.

So what is Honda Malaysia going to do next? They are going to close the case and want me to TEST DRIVE the car for them. No compensation. Nothing.

So I said, I will go to Facebook and Consumer Board, which they said "We cannot stop you from doing that". =_=

Guys, what should I do now? I'm very pissed off seriously. They are asking me to risk driving a car which can stop anytime (because they are not sure if they have fixed it) and is unwilling to help any further. What kind of nonsense is this?

I'm thinking to go to consumer board for this, and maybe see if I can contact Honda Japan. They might not help much...but this is regarding the safety of the car itself. Some other CIVICs out there might be having the same issue but has not happened yet.

Aih....i seriously long time never so angry already.

A loyal Honda supporter....now I'm becoming a Honda hater.

NOTE: the above is what I could remember from my many phone conversations with Honda Customer Service. I'm sure they have all the recordings with what have been said by Honda rep and myself.

Hi bro RON408. I believe it is true. I know details of the mods carried out to prevent premature carbon build up on EP6CDTM. If you or anyone is interested,I could writeup a summary for the benefit of all to understand this issue better.

Bro SKYjack , please do write that summary, interested to know more, is it also true that the new batch of 508 now also uses the same to prevent carbon build up?

On the 508,ECU has been remapped. This has adjusted ignition timing. Ignition now commences after inlet valve closes. This has reduced carbon buildup at the inlet valves. This improvement together with giving the 508 a good run every now and then helps reduce premature carbon buildup.

However I think ( and this is only my opinion ) 508s that are city driven or driven mildly all the time may suffer from premature carbon buildup. I will write how the problem is solved on the 408t, shortly.

Just now were you at Ampang area ?
I was beside you at the junction before Ampang Point in the 406.

looking at you, beep my horn...wanted to say hi but you didn't layan me.

Will definitely update my case here in the forum.
One question: will aggresive driving style reduce possible carbon build up, if any?

Hi,

You are almost welcome. Writeup. Share with us here.
Sharing is caring. Hehehe

Hi Skyblu3~ Yeah, yesterday my hubby and I went to have Korean food there and straight to Speed City to see ppl drift + burning their money on the track. Sorry for that. Next time horn twice for more attention coz its common if you horn once and we thought we are blocking somebody else.

I'm not sure if aggressive is the right word,but certainly taking your Lion out for a good run once a week keeps her roaring healthy! I'd say 150kmh for 30mins once a week!

Here is the summary I promised. Happy reading!

EP6CDTM
This is a direct injection turbo charged engine, presently used on 408t only, on pugs.It would not surprise me to see wider use of this engine due to it's enhanced reliability,in the near future. Whilst DI engines are more efficient, it also has sever carbon buildup prematurely.

It was widely believed this engine carried 6 mods to address reliability. I did a fair amount of research and found 8 mods were done. I see people now cut and paste the list on mods I put out. That's fine if it's going to get wider attention,I'm all for it! It will be too long to discuss all 8 mods. We'll look only at how premature carbon buildup issue is addressed on this engine. IMO all 8 mods have tremendously improved reliability of this Prince.

Meaning of some words I will use:
DI - direct injection
Carbon creep - slow process of carbon buildup
Premix - fuel/air mixed before entering cylinders
Wall wetting - fuel spray on cylinder walls
Fuel wipe - wipe tendency of fuel
Well - dug out surface in the shape of a well
Cup - circular dug out surface

Problem: Intake valves carbon buildup
On DIs fuel is not premixed and injected via the intake valves, it is independently and directly injected into each cylinder. Fuel has a cleaning agent. As a result of direct injection the valves have lost fuel wipe condition. Intake vales are open for fraction of seconds during ignition. During this period there is carbon creep on the valves. As fuel wipe is absent,over a short period of time carbon builds up on valves and prevents proper valve operation.
Solution: Remapped ECU. ECU is programmed to command ignition after the inlet valves are closed,thus preventing carbon creep.

Problem: Cylinder carbon buildup
As fuel is directly injected into the cylinders, it causes wall wetting. Wall wetting contributes to premature carbon buildup internally.
[/B]Solution: For the first time on this engine,pistons are redesigned to control this wall wetting. The redesigned pistons each incoperate a combination of a central well and periphery cups on piston heads. By this new design air/fuel mixture tend to be guided towards spark plugs. Better combustion is achieved. However rare occasions of fouled plugs. I think probably due to prolonged sedate driving. A good run once a week clears this rare tendency.

I like to remind bros, this is a very simplified version for easy understanding. I have intentionally left out a lot or details as this is only a summary.
