Important! : sudden knocking

  1. #1
    a 2000 1.1 saxo, when driving usually on the 1st gear, a sudden knocking happens as if the car has been switched off for a few seconds.
    can anyone help me, any ideas where the problem is coming from

    Can you hear where the knocking is coming from?
    Like, from a specific wheel arch, gear box or the engine?

    Is it when you let of the throttle? Mine done it turned out to be the gearbox mount
