after chg lub also same problem... SC mech still cant find the real cause.


I don't think its the lube problem. Since normal Campros don't have this noise, maybe it is unique to CFE as it was reported that CFE has a very high percentage of new components. Maybe the new design didn't retain enough lube after engine/oil pump is switched off.

My 4G92P took about 5days or above for the FS lube to settle in the oil sump and rattle like the youtube video upon cranking. Kancil 660 also took about the same; <>5days before got that noise but on SS lube. If it is really engine internal design oversight, then jialat lo.....

If it is starter problem mentioned by chargerguy, then it should be easy to solve as it won't affect long term reliability.

But then, TS's problem may not be related to the noise mentioned in the youtube videos.

once i drove friends flx cvt . put reverse before the engine is up to operating temperature and its sounds like so. maybe the system is trying to maintain the idle repeatedly in conjunction with the load given by the transmission when the engine is still cold. vom vom is safer than voooooooom that it might push or surge the car or extra effort on brake.

just guessing. the right answer should be well explained by proton engineer somehow.


To correct a bit. the sound I heard is like some kind of spinning sound. It does not go away even when engine is hot (after driving). I always hear this spinning sound when I put into reverse gear but brake is applied. Guess something to do with the CVT gearbox or maybe it is 'macam ini punya' for Proton.

I don't have the engine-starting sound as posted by NTC above.

So far very satisfied with exora. It feels solid when driving. Just hope this feeling last me for at least 5 years smile.gif.
