might be the air filter box is loose, which happened for my case, just check whether the box is loose anot.

i always hear this metal coming from the left of the car when seated in the driver seat when i start and move off.. one metal knock at 10kmph then 5metal knocking sounds when at 30kmph... its been bugging me... so its the ABS testing sound???

as for the rattling when accelerating and can be heard clearly in multi storey when your car is surrounded by walls, i had that before also...

confirm its engine knocking due low octane fuel used. try higher octane fuel.... really remove the knocking.

Hi,

I also encountered the same problem, went down to kelvin's workshop to check.
Was told is common among lation.... Try higher octane fuel, the noise reduce.. But sometimes still can hear..

Bro, I thk my sound gone ord. Went to Kelvin's plc to change some things n clean throttle body. After doing that he plug in the OBD device to reset back the engine settings n now engine is more responsive, smooth, FC improved n torque increased. Like what Jazz said engine ping could be the cause(guessing only) n I'm still using 95oct petrol. :thumbsup: :thumbsup:
