When I complained about overcrank to CoSE during my 10k km service, they diagnose with ECU update but overcrank still occurs.

Definitely will request for the carbon clean up during my next service. Hopefully can fix

i got rattling sound on my right dashboard when jalan on uneven road. anybody here got this problem?

You should CONTINUE give them feedbak & updated them that they have yet to resolve the overcrank issued, asked them to adv what to do next to have this resolved. Last time I also compliant to them right after my 6K service & went back to check but can't find any abnormality then claimed my Brake safety lock causes all this nonsense... Till I raise my voice only then the foremen asked to log into "MRR" to get adv for next course of action.

Since your EB need more them 3 times to overcrank frequently, why don't you video/sound record it & show to them during the complaint?? This will definitely help to speed up the troubleshooting I think..

Can you record your 1-time crank and engine start?

2-3 cranks to start is very normal for my car. It has been like that since day 1

Now i know what do you mean by overcrank mine normally 1 go. And on rare occasions, twice..

Finally able to record a video of the over crank happening.

I tried to crank the first time and the engine wasn't able to start up, I stopped after 4 cranks.
Quickly grabbed my camera to record the second start up try.

This happened at 9.30am in the morning, the weather was quite cold as it has been raining the past night.

Normal start up requires only 2-3 cranks. Over crank at least 6+ cranks for engine to start up.

Engine is able to start up after over crank, but feels very weak and will usually die, unless the accelerator pedal is stepped.

This has been happening ever since the first 1000km service. Recently had my ECU updated during my 10000km service as it was reported that the problem would be solved with the update, but obviously it has not been fixed.

Its sound like weak battery for me. Need few crank to overcome inertia. The battery may dead soon. Check the voltage in the morning. For Calcium-calcium maintenance free battery should be >12.8V. For wet battery, the minimum voltage should be > 12.6volt. I noticed water level in one of the cell in my "maintenance free" (the one closest to the engine) evaporate much faster than other and causing the over crank.

That's good & you should shown this to the service center & have them seriously look into your problems. Told them if they can't have this resolved then escalated to Proton Headquarter.

Where and how to check battery voltage?

why not just report it to proton wecare immediately?

can use multimeter . or use any voltage meter.

OBD2.

can u share where you buy it? what brand and model ? TQ

Means I must check for the battery voltage when the car is still off?

I bought from ebay, shipped to Malaysia.
LYN got ppl selling, RM30 IINM.

Guys,

For me i always practice to crank AFTER the warning signals go off - abs & airbag warnings! Been doing tis with my old cars - Wira, Spectra, Optima. So far soo good. Only start up @ the 1st crank. Only twice got issues with my EB but in that case the 'gearbox' warning sign came off. After reflushing the ECU its now ok.

Just my 2 cents...

Yeah, that's what I used to do also. I even wait for the fuel pump priming process (the 'zzzzt' sound) to complete.

But, for past 2~3 months, I'd just turn on, wait 2 seconds, and start... no problem despite fuel pump still running and ABS lights still on... let it warm up for a while then drive. It's sort of a guinea pig thing to contradict myself, and so far the car starts and runs fine.

Thanks for the info bro.

Will try it out tomorrow morning and report back

edit : which widget is it? is it the "Voltage (Control Module)" one?

edit 2 : nvm I think I got it

I used to do that ever since I got my EB. I used to wait until all the warning lights go off before cranking.

But even so, my over crank problem occurs even if I wait. Thats why I choose not to bother anymore since it doesn't make any difference
