Technical Rattle above 2000rpm

[DSPLY1]

Hello , for a while now I’ve had this rattling noise occur whilst driving. When the car is sitting at around 2000rpm there’s a rattling noise as shown in the video below and no one can diagnose the issue. Any help will be much appreciated

The things that rattle on my cars most often are loose heat shields.

I’ve looked and I can’t see anything. It’s been at 3 garages and they can’t diagnose it. We thought it was exhaust and others say clutch but I don’t know. When holding it above it 2000rpm or whilst driving it’s worst and then as soon as you dip the clutch it goes away?

I've also had a loose oxygen sensor on the exhaust.

The airbox can rattle like that too.

Ideally you need your head under the bonnet when someone else revs the engine.
