Hi YETTI, they said that they were able to adjust it, but also said that if it happens again, it will need replacing.
Three years on, it has been ok, HOWEVER, recently noticed a similar knocking sound when pressing the accelerator sharply. So when I step on it, 2-3 knocks and then the RPM's jump.. I guess I'll have to visit them again..
