E70 35d weird noise from around coolant reservoir

It will only happen when the engine is warm. When the engine is running, this noise will keep going at the same level and will fade away after shutting the engine down.

As of now, I do not notice any effect on the performance, but concern that it will eventually since the noise is getting louder and louder. Thanks for any input!

is it louder under the right side of the manifold? specifically around here?

That should be about right there where you circled.

Probably a dying pressure convener

Turned out it was from glow plug module. Now it's all good!
