2.0 TDI rattle sound

[Kvint]

Hello everyone
Have Audi A4 B9 2019 2.0 TDI 190 ps, DETA
Starting from 1500 rpm an unpleasant rattle sound is heard, which disappears when the gas pedal is released. This sound is clearly audible at the driver's feet. I tried to record this sound:
Maybe somebody have ideas? I changed fuel pump. fuel injectors - no change(

Still nothing unusual to hear unfortunately.

“Hi, I can hear the same vibrating sound when I accelerate, but it disappears when I release the gas pedal!”

“Did you manage to figure out what was causing it?”

Hey, did you find out what it was? Got the same sound coming from my car.

There's no point posting these types of videos as the background noise makes it difficult to isolate anything untoward. If it's a rattle, then nine times out ten it's a heat shield under the car. The fasteners corrode and the heat shield rattles. Also check brake dust shields, but this would be unusual on a 2019 B9. Lastly check the main exhaust straight pipe where it joins after the catalytic convertor. The exhaust clamps eventually corrode. Mikalor stainless clamps are the best you can fit.

If you can trace and localise the sound, that's different, as you will be able to get a more detailed video.

Well problem is that you can hear this sound only at certain speed or rpms, like in my car you can hear it above 30km/h.

Listening to audio recordings has always been a problem for us. We each become attuned to the noises our own car makes, so when an unusual noise occurs the human brain can mentally filter out the normal noises and hear the abnormal noise. Unfortunately when a stranger hears an audio recording he hears every noise and can not distinguish the abnormal one.
