@digifish Ignore my last post, I must have misread your post. You are right about vibration isolation failure.

No it wasn't. It was old rubber rings that were passing vibrations further into the cabin trough body. They're part of the bracket that holds the valve.

The part number is 046 131 887 if anyone would be interested.

So today I've changed rubber grommets (part number 20 in the diagram a few posts above) and the noise disappeared

I've replaced the pressure converter but the sound still remains. So it must be some part of it's holder that's transferring the sound into the cabin. I've also ordered new grommet, but I don't have it yet.

So I know what's causing it. A kind user on different forum found out that the noise is produced by Exhaust Pressure Converter (part number 1K0 906 627 B). It is fasten right to the other side of dashboard. I don't know yet if it caused by the converter itself, or by bad grommet. I've ordered new converter and will let you know.

Hi, I recently bought this car and it starts making low tone noise at around 1100 rpm. It's hard to describe so I've included link to video where you can hear it. It's happening in regardless of gear and also in neutral, when stationary and moving, mostly when throttle is applied, but I've heard it a few times without throttle applied at speed around 50 km/h. Do you know what could be wrong with it? Engine: 2.0 TDI CR 110kW Transmission: 6-Gear DSG Model year: 2016 Link to video: https://www.youtube.com/watch?v=DPM4KIdDazs Thank for all responses.
