Clicking noise at the clutch point

Hello. My car is a 2010 model 207 1.6 HDi. Lately, there's been a clicking noise in the clutch area of first gear and reverse gear that doesn't always occur. It sounds like a loose screw, especially when trying to start at low rpm or when the vibration increases on hills. The noise seems to be coming from the right side of the engine. Has anyone experienced this before? What's causing it? The mechanic looked and couldn't find it. Does anyone have any advice?

Hello, there could be many reasons. It could be the tie rod end, axial shaft, base, axles, even a loose bolt as you said. And finally, it could be caused by the flywheel.
