Boxer 2.2Hdi engine sound

[Drago94]

Hello to everyone. I own the Peugeot Boxer 2.2Hdi 88kw 2010. I have a question about engine sound. When the engine is cold, so
it makes a weird sound when I hit the gas (idle). The warm engine makes a noise also but better.
There is my video of sound: https://www.youtube.com/watch?v=fMeIZoFgP18

Thank you

What happens if the clutch is activated in the process? Sounds like a defective dual mass flywheel. Have a local professional assess the case.

Dual mass flywheel and clutch were changed about month ago.

But then it didn't last long. Coupling must be pre-tensioned on the model before tightening. Have the noise checked again in a specialist workshop, maybe it is something else.
