Hi all
Recently my wife gotten the delivery of her Viva Elite auto, and have been driving it for the past 2 months. Have done the 1000km service, and now scheduled this weekend for the 5000km service.

Before the car goes off for service, I would like to ask, does anyone here have problems with the engine knocking? I m surprised to see the new Viva does ping when going uphill, or under heavy right foot. We have also tried RON95 and RON97 fuel, but with no avail, the engine still knocks, which is very very strange as the knock sensor would at least stop the knocking.

Does anyone have this problem, and how can I resolve this? Do we need to get Perodua to plug in the computer to check on the sensors or re-tune the car? Please advise, thanks !
