Hello folks, can anyone identify this rattle?
It appears when the car is fully warmed up, and is mostly present when standing in place in Drive mode. It's goes away as I accelerate. It's not persistent, but like 80% of time it's there.
It went away for a short while after I replaced the transmission side engine mount, but came back after few days.
It's not very audible from outside or from the engine bay, only clearly audible from the interior. Sounds like it's coming from below center console area, but I may very well be wrong, it;s hard to pinpoint.
Any idea what could it be?

 

Exhaust heat shield maybe?
