Hi there, hope you can help. The clutch is making a knocking noise when close to biting point and when in gear the noise escalates when accelerator is pressed however when taken out of gear the noise disappears. I don't know much about cars but seems to me maybe the clutch but have various different diagnosis's. What would be the safest guess/diagnosis and how can I be sure? Thank you very much and am very interested in any help on resolving this.
