The reasons for the abnormal noise at idle speed that disappears when the clutch is pressed: It may be caused by the loosening of the release bearing on the clutch, or it could be due to loose input shaft bearing of the transmission, transmission gear failure, or transmission fork failure. When there is noise in the engine compartment and the noise disappears when the clutch is pressed, it can be determined that the noise originates from the transmission side, specifically the area of the clutch and transmission. To check the noise from the clutch release bearing, this is caused by the loosening or detachment of the release bearing. The shaking produces a rattling noise, and pressing the clutch pedal presses the bearing against the clutch pressure plate, causing the bearing to rotate and the noise to disappear. Replacing the release bearing will solve the issue.
