Mine's a diesel though, dealership said it was a normal turbo noise. I don't think so.

I'm just trying to get more evidence on it, but life takes over :-/

Yes, hitting the throttle reproduces the noise, both on the increase and decrease, but only when the engine is at that 1000 rpm mark. If throttle is held there, noise will be constant.
