Hi All,
Can somebody help what can cause knocking sound which it does not appear all the time but after some driving and only in idle state, that is when the clutch is released and car is in idle state. As I can hear it looks like it comes from the right side of the engine but not completely sure. I've provided videos for more information. The car dealer said that is some default factory fault for all fabia mark 3 engines, but i'm not sure on that. The engine is 1.0 MPI 44 KW for more details.
