Cel

[Guest raymond]

Want to know whether have anyone here has similar problem.

Drove my C230 up to KL and returned yesterday. Filled the car with Shell V-power at Johor side and after which the CEL (Check Engine Light) lit. I have checked the engine oil level - normal and also tightened the fuel cap again.

The car feels normal in all conditions even though the CEL is on.

I am going to STAR tomorrow to find out, but in the mean time, anyone with similar experiences?.

[Guest jhun_4040]

Is ur CEL still on after u switch off and on ur engine again ??

[Guest raymond]

Yes, Still on. I also did a ECU reset ie- fully depressed the throttle while key in ACC position for X second, etc....still on as well.

Huh? ECU reset like that one meh?

[Guest io5885]

Try these steps to reset.

Key positions:

Position 0: when the key is just inserted into the slot without any turning.

Position 1: turn the key one click to the right (clockwise).

Position 2: turn the key another click to the right (clockwise). This should be the last position before you crank the engine. To confirm that u are in this position, all your dash board warning signs will be displayed like a christmas tree decoration

Position 3: Crank position if u turn the key one more click to the right (clockwise) but note that this position will automatically return to Position 2 once you release the presure on the key.

Rest ECU/TCU steps:

1) Make sure your car is stationary with the engine switched off and key out of the ignition and in your hand

2) sit in the driver seat

3) insert the key into position 0

4) turn the key 2 clicks clockwise to position 2

5) step on the accelerator pedal fully to the floor (until you activate the kickdown button at the end of the pedal travel) and hold for > 5 seconds. Don't need to be exact but I usually wait for about 10 seconds just to be safe..

6) now with your right foot still fully depressing the accelerator pedal, turn your key counter-clockwise to position 0 and hold for >1 second. I usually hold for 3-5 seconds with detriment to the effort.

7) now release your right foot from the accelerator. Your key should still be in the ignition hole at position 0.

8) Wait for about 4-6 minutes (the timing have been reported to varies across different models)

9) in the mean time do not touch anything electrical/buttons in the car as the ECU/TCU sort of "reboot".

10) when time is nearly up, listen for a single "tack"-sound coming somewhere from the steering column. That is indication that your reset is successful

11) now take out your key from the ignition hole and you are done.

12) if you want to drive off immediately, still must complete step (11) before re-inserting the key to start your car as usual.

After reset, you will notice that your car holds the gear longer as you drive around. Some say drive around your usual style so that it will learn it and adjust to your style optimally. Some say drive it aggressively for 10Km so that it will learn the more aggressive driving shifting and your car will be more responsive. What ever it is....you can try both ways...it's free anyway.

Thank for the assistance guys. Star Black told that from the error code, the CEL is for a misfiring in Cylinder no. 4.

So far they are not able to replicate the problem....so I guess I have to keep my finger cross that this won't happen again.

The importany question is why

[Guest raymond]

Unfortunately, they could not find out "WHY". Told that they have tested each cylinder individually and still could not find any problem.

I had the same problem pumping Boleh land Shell and my car stalled in the middle of heavy traffic in downtown Penang. Went to authorised workshop and was asked the first thing, "Did you pump Shell?" Even they knew about it.

Since then, which was about 3 years ago, i vouch never to pump petrol Shell again,... even in Singapore. And i could not replicate the same problem I had then again.

Across the causeway now, i always pump Petronas as i understand their fuel quality is the best.

[Guest io5885]

I :second: that!!

为什么?...为什么?...为什么??? 十万个为什么??? ：confused：

So far i never had problem with spore shell... but i dont trust the brand anymore.

[Guest subaru67]

[Guest hannson]

Thanks bro for sharing info!!!!

I have similar experience with SPC in Singapore

CEL after pumping highest SPC grade.

Couldnt determine why either

[Guest io5885]

Is it in the period after some china company bought over SPC?

For CGI cars, they are made to drink RON95 best. If anything higher, it's possible that the firings in the pistons are too hot or premature...giving rise to CEL.

hi bro

er.. higher.. means Ron 98 or Ron 92?

Usually the bigger the Ron number .. means less likely to "pre-ignite".

"The Octane rating is a measure of how likely a gasoline or liquid petroleum fuel is to self ignite. The higher the number, the less likely an engine is to pre-ignite and suffer damage."
