Clicking sound under car - C class w205

[muhib777]

Hi, i have a strange clicking sound on car which appears after driving some city journey trips. Very noticeable during idle. But sound also appears during driving with window down.

Sound appears under the car and appears constantly after few seconds, same sound and rhythm.

I first thought it was heat shield or metal expanding etc. I dont think this is the case due to the same pattern sound constantly.

Heating system is also off, i had doubts its ac related. (Could be still)

Any ideas what it could be? Please see link below to short youtube video clip.

I dont think this is the issue as the sound appears when cars on idle stationary aswell. The propshaft and brake cable wouldn't move even if the clip was broken.
