hello all.

my wife elegance suddenly having problem with "check engine" light. It happened yesterday while going downhill bukit tinggi. we went to genting on 1st march, check in, and 2nd march check in at bukit tinggi.

so far nothing wrong with the car. petrol consumption is ok, no sudden engine died in the middle of the road. I drove from bukit tinggi back home in ipoh yesterday without any drama. i tried to reset the battery n ECU, still the same.

today my wife send to SC somewhere in ipoh. the mechanic check the ECU and found that it is giving unrecognized error code. they recommends to replace the ECU. my wife car elegance 2010

i wonder that the downhill caused the damage to the ECU box

i'm thinking the same too, seems like the reply is a bit cincai. so the easiest is to replace. They quote rm800 for the ecu including labor.

during our getaway between genting and bukit tinggi, we had plenty of uphill and downhill few times. As i dont want to rely too much on the brakes, i always use engine braking (auto gear btw) shift to 3, and stays on 2 most of the time. if the downhill got too steep, then i brake harder and changed to L. Of course from 2 to L, i made sure that the engine speed was adequate before changing to L.

roger that, now trying to go to other SC for second opinion. If the second SC also said the same thing, then no choice lor.

what i scared the most if change the ECU, then things get worse than before like car stranded etc. If i were driving, then i can manage something during emergency. But since my wife drive it all the time to work, a bit worry if she is alone somewhere.

will consider your offer depending on what the second SC diagnosis, thanks

unfortunately i'm from ipoh, too far

today my wife sent to a different SC. to our surprise, this SC said from their computer, the ECU code is showing the O2 sensor faulty. So now proceed to change the O2 sensor since it is way cheaper. and yes, the warning light finally gone. Thanks for your advice guys, especially to double check with a different SC

the proton SC from yesterday really cincai

i'm using the black sellotape as well
