2015 CR TDI 184 Rattle

So, this actually relates to my Leon, but it’s the same as the Octavia so wondering if anyone has any idea what this plastic sounding rattle may be? Started today.

It sounds like it’s coming from the left side of the engine, is this where the timing belt is? Car still drives and feels fine. I know the engine is noisy normally, but this is definitely a new sound.
