Rattle Noise CR TDI CFBG Engine - Diagnosis

Hello,

My Golf GTD CFBG now has almost 25,000 kilometers on the odometer, and it's now making strange rattling noises under partial load, specifically in the RPM range of approximately 1500 to 2200. The problem seems to only occur when the engine is warm; in the morning, when the car has been standing, everything is quiet, but after driving for a while, the noise starts.
It's not loud, but it's clearly audible when the radio is off.
It's definitely only audible under partial load conditions.
People read about similar problems in various Skoda and Seat forums, and in those cases, it's often attributed to the high-pressure pump. However, according to the state of the art.
Can anyone comment on this? My car is only just under 1 year old, and it already sounds broken.

Hello SLG60,
Listen to mine.

Is it the same thing? Some people only do that when it's warm.

Hello,

That's not happening in your car, but it only happens in mine when there's a change in load or when the engine is running at partial load.
I've also noticed that there are days when it's gone... I'm quite at a loss.
