if is under warranty u can ask them to check. Might be sensor problem

when you on the way back after roll down genting like chu cheong fun, how is the weather?

Did you go over any water puddle or small flood?

Go Cose complain

i kena b4.. but not check engine light..
is the engine oill.
cause that time i travel .raining.
and water herre and ethere,
and i suspected maybe the wire wet gua,.,.
atfer drive for 1/2 hour.. the light no longer light up

Go Cose complain

Only chemical smell

last time when i drove down from cameron highland during wet weather, the light also went up.
then i ask about it here and some suggested that it might be the fuel lid not tight, but i dun think that is the reason.
then just after a day, when i start my car again, the light when off.

now i believe the probable reason will be the O2sensor. just maybe.
K.Lee, so for the moment your car no smell alr? nice.

i heard that when the engine warning lights up, a log will be made in the ECU, is it correct?
since then the engine warning never light up, and i did ask them about during my regular service to check the ECU, but they told me nothing wrong detected.

Anyone has idea on sour smell aircon?It comes out for about 5 sec afta starting the car.Then its gone..I changed the cooling coil,filter,drier.

Any solution bro?

As what I told onijoseph before, it may be a case of pressure difference in fuel tank that causes the engine check light to come on. A loose fuel cap is also possible, but I changed my views a little bit on that. A loose fuel cap may cause the engine light to come up as the fuel pump requires pressure to work (for carburetor cars), and that the change or lack in pressure can be detected by the fuel pump sensor in the tank (both carburetor AND fuel injection cars), thus causing the light to be on. If the fuel tank is tightly shut, when you go uphill/downhill there are pressure changes around the tank, but not in the tank.

Guys that've been up Genting with me before in my car would know exactly what I'm saying. All the empty bottles lying in my car that are tightly sealed expand/shrank due to pressure changes. Good demo.

But if you send your car to SC and they check, even if the light is already off, there still should be a log of what's bad.

How I wish that it's like BMW/Porsche's system where they tell you directly what's the problem on the dashboard monitor
O2Sensor? An O2Sensor that's not working will not suddenly jump back to work. I'm not saying that a faulty O2Sensor would not cause the engine light to come up, but if it's left untouched and your car is still new, there is no reason it would cause the engine check light on.

Yup need to leave there coz alot of work..Maybe izzit due to ambi pur?LOL..all these years no problem 1 leh..after i change the coil oso no prob..but a few days later,oni it comes..i even tried to off the compressor and let direct fresh air flow thru the vents..still cannot.

U muz go to main SC la..Authorized SC wan cari makan 1 la bro.

Which SC u went? Kasi blacklist!

weird

coz I suspect is just some kind of sensor is wet, hence the check engine light is on. Then after a few days, the sensor kering balik so the light is gone. Quite common case in Saga if the car went through flood. But your car dint go for a swim...

Suspect ka? Sensors that are not in the engine usually are more durable than they look la..
Sri Gombak? Any Siang Hin's SC already blacklisted lo.. Especially Gombak & Genting Klang ones..
