I am almost sure this is a common issue, on cold start then it fades away, mainly due to exhaust studs?

Can you please shoot a quick video with your phone so I can hear the noise? that way I can tell for sure what's going on. You can upload it here with your response. We need to hear the noise so we know which direction to go to help you fix the car. A cold-start tick that fades as the engine warms up is very often caused by an exhaust manifold leak, commonly from broken exhaust manifold bolts/studs bit I need to hear it to be sure.
