Thank you for the reply.
I live in India and use the regular petrol supplied by Indian oil company.
This problem occurs only at a speed of around forty kmph, not at higher or very low speeds.
At times I anticipate the knocking and shift gears using the paddle shift. It goes into third gear and does not knock on accelerating then. Hence I thought of a problem fue to the gear shift not occurring on time.
