Send the car to pml to have it checked. SA says its normal. Even the techs says its normal too. Any suggestions?

I understand it's from the ball joint of the stock absorber which is made of some plastic material. Changing to after market suspension setup will resolve the knocking sound.

If its an adaptive suspension it will be a waste to change to aftermarket suspensions...
