Can't even give you a good guess other than to say it sounds like some type of vibrating rattle from a dust shield or some other type of small metal part rubbing against the rotor maybe. Best wishes for the dealer to find it and make a fast, easy repair.

After thinking about what u said about something probally rubbing i was able to reproduce it at idle holding 1kpm and after my car warns up it goes away it appears to be my heat shield

I think its your npp valves rattling. The dealer has a fix for this.

No wonder that bugs you. That sounds like rocks in a clothes dryer! That is awful. At least you now know it's nothing rubbing the wheels or in the rear diff/half shafts since the sound happens in park. Interesting that it goes away once warmed up. Maybe it's in the exhaust system as mentioned.
