List of issues with mine so far with "possible" solutions..

8. Really poor performance & response when driving under 2k rpm.
    - this is when the engine is at operating temperature. When my engine is cold, performance is good and snappy most of the time (I'm not really sure is this all the time or not). Could be due to ecu pump rich a/f ratio during cold.
    - Also when driving at low speed and moderate rpm, when the aircon compressor kicks in, can definitely feel  my rpm dropped and a braking force exerted to my cars engine. In other words it sorts of jerked. In a manual...
    - Also, sometimes when shifting back to neutral and braking towards a stop. rpm stays at 1.5k and later on drops. refering to this (persoan vvt group)    https://forum.lowyat.net/topic/4011234/+1540  , could be due to faulty brake stop switch. Will check with SC on my 3rd problems trip there.

9. Metal rattling sound coming from engine bay when engine is under load or at a hill and warmed up below 2k rpm (could be during cold but mostly during warm).
    - Sample similar sound here at around 00:10s (sry duno embed)    https://www.youtube.com/watch?v=wCbi3FnuhTM...rLLRr-Q&index=1 
    - At first really worried as this might be pinging or pre-detonation sound coming from within my engines combustion chamber as in the short/long run will cause serious damage to my engine. I've researched that this is a common issue with campro engines especially during gen2 era (No one has a solid solution for this yet).
    - could be due to engine too hot and the mixture detonated before piston reaches top dead center. could be knock sensor problem. could be ron95 not compatible. could be bad cooling system. could be ecu problem. really lost here...

    - However from the video sample shown with similar sound, his solution was actually looking into the exhaust heat shield that was found to be loose. Thus this could be whats causing the issue. During my next trip to SC I will have them check this out also...
    - PLEASE BE EXHAUST HEAT SHIELD ISSUE...

---------------------------------------- End of issues currently with my Saga VVT manual 2016-------------------------------------------------------------

I will get myself an obd2 scanner as well for myself to diagnose my car to check if everything is supposed to be running as it should.

Again, car drives great but this issues (especially issue 7,8,9) must be solved asap before it gives birth to other issues. I guess in my case, its true that when u buy a proton u learn more about ur car and will have regular visits to the SC....

I am still keeping my calm as the car is still drive-able and not staying in SC emergency ward overnight....

i think because of the aircond compressor punya horsepower

I check out my car with obd2 already. No errors found. Everything should be running fine. Saw that my engine is constantly changing its ignition advance (must be my ecu handling it).

But I am however hearing pinging sound now on all gears under higher load when reach operating temperature.

If I'm cruising at moderate speed at a higher gear (let's say 80kmh on gear 5) the pinging sound is audible but I don't feel any jerking or vibration from my engine or my steering wheel, does that mean I don't have pre-ignition problem and this pinging sound could be coming from somewhere else?

1. Coolant is good.
2. Oil level is good.
3. Not due service for another 3500 km
4. It happens all the time when in low gear and higher load. Like gear 3 in sub 30kmh.

Could be loose heat shield as I've discovered from other people's solution to this problem over the Internet.

Also ron95 should be no problem since this car is designed to run on 95. And Ron97 is not cheap.

It was in gear 2. In this case in the video yes it can be said I am lugging the engine since I sudden depress the accelerator massively at low speed and on a hill. This just to show case the pinging sound. However this sound happens way to often now even on straight rounds at high speeds in every gear when accelerating. I suspect it has got to do with my ecu ignition timing.

The sound wont appear only if I constantly keep my rev above 3k rpm at least before accelerating be it gently or harshly. In order to avoid this pining sound from happening to often i need to drive my new car like i stole it. Trying to keep it above 3k and shifting gears from 3.5k ~ 4k rpm.

When i got the proton saga aeroback like 15 years ago (manual as well) it did not have this sound at all as a new car until it has surpassed 10 years old. haizzzzzzzzzzz

i've tested this out.

1. Car is stationary in neutral gear.
2. On air-conditioning (A/C on)
3. Place feet on accelerator lightly (around 5% depression) and not moving my feet as hard as i can. RPM stays @ 2500 rpm.
4. Wait for air-cond compressor to turn on.
5. Air- cond compressor comes on.
6. RPM drops 500 to 2000 rpm while feet still constant at the accelerator.
7. Compressor turns off. RPM goes back to 2500 rpm.
Now the question is, is it supposed to be like this? Isn't my ecu supposed to tell my engine to compensate that loss of 500 rpm??? Something is definitely not right here.

My car really drives good when air cond is turned off and sucks significantly when it is turned on.

Cool. Just realized saga used their bare basic saga to do the asean ncap. But why din't they did the premium one as well like how bezza did for their lower tier and top tier bezza?

Their marketing strategy really questionable as well as not even adding on basic abs on their low tier car . I guarantee if they offered executive with a manual I'll buy that within a heartbeat

Don't know whether Proton has updated the steel used in the 12 year old chassis but I'm thinking maybe certain elements of the platform design i.e crumple zone or more weak points  is why it didn't score as well as newer platform cars like the Iriz, Bezza etc.

Maybe when the GDI engine arrives early next year the Saga will have EEV certification. I've seen the reports say some of the parts like the cylinder head will be made of aluminium and the exhaust manifold is integrated as well which saves some weight.

Interestingly though, the GDI lineup does include a 1.3 engine which is the same displacement as the current VVT engine. There might still be a possibility that the engine will be making its way to the Saga, just in the higher trim variants like the Premium. The Standard variant would likely still have the VVT option.

I'd say if P1 chooses to keep the old VVT engine, then the first thing they do following the partnership with either Geely or PSA is to improve on certain flaws of the VVT engine technology and sell the engine tech on a license to another company for their small cars. That way, the engine remains relevant for a few more years and P1 gets some extra profit should a company purchase the license to the technology.

Their engine might perform better, but it won't be as reliable as Campro.

It's proven by existing proton cars that used Renault engine and transmission.

Here's the fuel consumption after driving Saga Premium a month;

Urban-suburban (no jam), 80~110km/h : 11km/L, ~9L/100km
Highway (JB-KL), constant 120km/h : 15.7km/L, ~6.4L/100km

Odd thing is I could only pump ~33L when the low fuel warning comes up.

At Proton Cose now to settle some minor complaints.

About proton campro vvt pinging. Confirmed by the proton technical team that it's meant to ping due to double overhead cam adjusting between advance and retardation in milliseconds (something like this la he says). It is indeed misfiring but will not damage the engine in any way. It is designed like this.

He owns an Iriz and is facing similar symptoms. He mentioned using fully synthetic does help to reduce the occurance. Maybe I'll try in next service. Maybe (too expensive )

Even if EPS is included, Saga still couldn't get EEV status because it's heavy.

bezza i know blogger test bezza engine die twice lol high spec and auto

can, but i hear engine knocking sound, been using ron95 for 5 month before, but after trying 97 in few pump, never turn back
