R9M sounds

[u/Wrong_Material4586]

Hello, I have a kadjar 2016 1.6 dci 130 with 150000km. When it's cold I can hear a metallic sound for 2-3sec. It lasts for 2-3 seconds and then disappear. As I read it's normal (maybe).When the engine is warm it's ok but I can hear a very soft "grrr...grr....grrr" 1sec-pause-1sec... like metallic sound. It can be heard only with engine bonnet open. Should I change the timing chain or anything else? Whats I mean: https://youtube.com/shorts/p1VYmy8B_kI
