.I need an advice. Only when driving in any gear, including reversing, can I hear knocking under the bonnet. When I set to neutral, the knocking sound disappears. Knocking sound speeds up along with higher speeds. Knocking is heard from about 10km / h. The tachometer shows 105,000km. I wonder if it was time to change the clutch? How will a bad clutch manifest itself?Thank you very much
